Read `docs/work-queue.md` and do the next unchecked batch. For each batch:

1. Read the engine files (`mtg-engine/src/abilities.rs`, `mtg-engine/src/game.rs`) to understand current Effect/StaticEffect variants
2. If the batch has a NOTE about uncertainty, investigate first and update the queue with findings before committing the fix
3. If engine work is needed: add the variant, constructor, and match arm, and look for the Java implementation to see the bigger picture and understand nuance
4. Add a test for any new engine effect (follow the pattern in `game.rs` `mod tests`)
5. Fix all cards listed in the batch (grep to find exact lines, fix across all 4 set files)
6. `cargo check -p mtg-cards && cargo test --lib`
7. Update docs: mark cards in `docs/{fdn,tla,tdm,ecl}-remediation.md`, update `ROADMAP.md`
8. Check off the batch in `docs/work-queue.md` with today's date
9. If you discover new cards that fit the current or a future batch while working, add them to the queue
10. Double check that the implementations work similar to how the Java engine works

If a batch turns out to be wrong or more complex than described, update the queue with what you learned and move on to the next one.

    18→## Batch 1: LoseLifeOpponents [DONE 2026-02-13]
    19→
    20→**Engine**: Added `Effect::LoseLifeOpponents { amount }` variant + constructor + match arm + test.
    21→
    22→**Cards fixed (8):**
    23→- [x] FDN: Marauding Blight-Priest, Pulse Tracker, Vampire Spawn, Phyrexian Arena (LoseLife), Vampire Neonate
    24→- [x] TDM: Skirmish Rhino
    25→- [x] ECL: Champion of the Weird (effect part), Boggart Mischief (dies trigger part)
    26→
    27→---
    28→
    29→## Batch 2: Easy swaps — existing typed effects [DONE 2026-02-13]
    30→
    31→**Engine**: Modified `execute_effects` in `game.rs` to accept an optional `source: Option<ObjectId>` parameter. When `AddCounters` or `RemoveCounters` effects have no targets, they now fall back to the source permanent (for self-targeting counter effects). Added test `add_counters_self_when_no_targets`.
    32→
    33→### 2a: DestroyAll — Day of Judgment
    34→- [x] FDN: Day of Judgment — `Effect::Custom("Destroy all creatures.")` → `Effect::destroy_all("creatures")`
    35→
    36→### 2b: EntersTapped — Diregraf Ghoul
    37→- [x] FDN: Diregraf Ghoul — `StaticEffect::Custom("Enters tapped.")` → `StaticEffect::EntersTapped { filter: "self".into() }`
    38→
    39→### 2c: CantBlock (target) — Frenzied Goblin, Brambleback Brute
    40→- [x] FDN: Frenzied Goblin — `Effect::Custom("Target creature can't block this turn.")` → `Effect::CantBlock`
    41→- [x] ECL: Brambleback Brute — `Effect::Custom("Target creature can't block this turn.")` → `Effect::CantBlock`
    42→- **Note**: The work queue originally listed "Skoa Veteran" for batch 2c, but the actual card in ecl.rs was **Brambleback Brute**.
    43→- Verify: these cards already have `TargetSpec::OpponentCreature` or similar targeting
    44→
    45→### 2d: Self -1/-1 counters — ECL blight creatures
    46→These use `Effect::Custom("Put N -1/-1 counter(s) on <self>.")` alongside working effects. Replace with `Effect::AddCounters`:
    47→- [x] ECL: Blighted Blackthorn (x2) — `Custom("Put two -1/-1 counters on Blighted Blackthorn.")` → `Effect::add_counters("-1/-1", 2)` (appears twice, two abilities)
    48→- [x] ECL: Sourbread Auntie — `Custom("Put two -1/-1 counters on Sourbread Auntie.")` → `Effect::add_counters("-1/-1", 2)`
    49→- [x] ECL: Sting-Slinger — `Custom("Put a -1/-1 counter on Sting-Slinger.")` → `Effect::add_counters("-1/-1", 1)`
    50→- [x] ECL: Heirloom Auntie — `Custom("Remove a -1/-1 counter from Heirloom Auntie.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    51→- [x] ECL: Encumbered Reejerey — `Custom("Remove a -1/-1 counter from Encumbered Reejerey.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    52→- [x] ECL: Reluctant Dounguard — `Custom("Remove a -1/-1 counter from Reluctant Dounguard.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    53→- [x] ECL: Bristlebane Battler — `Custom("Remove a -1/-1 counter from this creature.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    54→- **Engine tweak**: `execute_effects` now falls back to the source permanent when `AddCounters`/`RemoveCounters` have no targets (self-targeting counter effects).
    55→
    56→### 2e: Loot (draw then discard) — Icewind Elemental, Refute
    57→- [x] FDN: Icewind Elemental — `Custom("When this creature enters, draw a card, then discard a card.")` → `Effect::draw_cards(1), Effect::discard_cards(1)`
    58→- [x] FDN: Refute — `Custom("Counter target spell. Draw a card, then discard a card.")` → `Effect::counter_spell(), Effect::draw_cards(1), Effect::discard_cards(1)` + fixed TargetSpec to Spell
    59→
    60→### 2f: Simple ETB draw — Mistmeadow Council
    61→- [x] ECL: Mistmeadow Council — `Custom("When this creature enters, draw a card.")` → `Effect::draw_cards(1)`
    62→
    63→### Cards NOT fixed in Batch 2 (deferred):
    64→- **Warren Torchmaster** (ECL): compound Custom with self-counter + target haste (needs modal/conditional support)
    65→- **Dream Seizer** (ECL): compound Custom with self-counter + opponent discard (Batch 3 dependency)
    66→- **ECL line ~1843**: "Put two -1/-1 counters on each creature." — needs `AddCountersAll` variant (new engine effect)
    67→- **ECL line ~464**: `Cost::Custom` for -1/-1 counter removal — not an Effect, needs Cost system fix
    68→
    69→---
    70→
    71→## Batch 3: OpponentDiscards [DONE 2026-02-13]
    72→
    73→**Engine**: Added `Effect::DiscardOpponents { count }` variant + `discard_opponents(count)` constructor + match arm in `execute_effects` (iterates opponents, each calls `choose_discard` then moves to graveyard). Added test `discard_opponents_effect`.
    74→
    75→**Cards fixed (4):**
    76→- [x] FDN: Burglar Rat — `Custom("Each opponent discards a card.")` → `Effect::discard_opponents(1)`
    77→- [x] FDN: Arbiter of Woe — compound Custom → `discard_opponents(1), lose_life_opponents(2), draw_cards(1), gain_life(2)`
    78→- [x] FDN: Bloodtithe Collector — `Custom(conditional)` → `Effect::discard_opponents(1)` (condition "if an opponent lost life this turn" not modeled; trigger fires unconditionally)
    79→- [x] ECL: Dream Seizer — `Custom(compound)` → `add_counters("-1/-1", 1), discard_opponents(1)` (self-counter via Batch 2 source fallback)
    80→
    81→---
    82→
    83→## Batch 4: Simple token creation [DONE 2026-02-13]
    84→
    85→**Engine**: No changes needed. `CreateToken` already works and parses P/T + keywords from `token_name`.
    86→
    87→**Cards fixed (8 cards, 10 effect swaps):**
    88→- [x] FDN: Guarded Heir — ETB `create_token("3/3 Knight", 2)`
    89→- [x] FDN: Prideful Parent — ETB `create_token("1/1 Cat", 1)`
    90→- [x] FDN: Resolute Reinforcements — ETB `create_token("1/1 Soldier", 1)`
    91→- [x] FDN: Release the Dogs — Spell `create_token("1/1 Dog", 4)`
    92→- [x] FDN: Dwynen's Elite — ETB `create_token("1/1 Elf Warrior", 1)` (conditional "if you control another Elf" not modeled)
    93→- [x] FDN: Dragonmaster Outcast — Upkeep `create_token("5/5 Dragon with flying", 1)` (conditional "six or more lands" not modeled)
    94→- [x] FDN: Searslicer Goblin — End step `create_token("1/1 Goblin", 1)` (raid condition not modeled)
    95→- [x] ECL: Clachan Festival — ETB `create_token("1/1 Kithkin", 2)` + Activated `Cost::pay_mana("{4}{W}")` + `create_token("1/1 Kithkin", 1)`
    96→
    97→**Tests added:** `framework_create_token_effect`, `framework_create_token_with_keyword`
    98→
    99→**Skipped/Deferred:**
   100→- FDN: Cat Collector (Food token) — Food tokens are artifacts, not creatures. `CreateToken` always sets `CardType::Creature`. Needs engine support for artifact tokens (new batch).
   101→- FDN: Faebloom Trick — compound effect: create 2 Faerie tokens + reflexive trigger (tap opponent creature). Needs multi-effect resolution.
   102→- FDN: Mender's Bounty (Food token) — same as Cat Collector.
   103→- All token copy effects (Electroduplicate, Rite of Replication, etc.) — needs Spell Copy system.
   104→- All variable-count tokens (Homunculus Horde, Hare Apparent, etc.) — needs dynamic count support.
   105→
   106→---
   107→
   108→## Batch 5: Ward keyword [DONE 2026-02-13]
   109→
   110→**Engine**: Added `StaticEffect::Ward { cost: String }` variant + `ward()` builder. Ward is stored as structured data; mechanical enforcement (counter-unless-pay during targeting) deferred to future engine work. `KeywordAbilities::WARD` already existed in bitflags.
   111→
   112→**Cards fixed (7):**
   113→- [x] TDM: Aegis Sculptor — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   114→- [x] TDM: Ambling Stormshell — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   115→- [x] TDM: Dirgur Island Dragon — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   116→- [x] TDM: Scavenger Regent — `StaticEffect::Custom("Ward -- Discard a card.")` → `StaticEffect::ward("Discard a card.")` + WARD keyword
   117→- [x] ECL: Bristlebane Battler — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   118→- [x] FDN: Cackling Prowler — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   119→- [x] FDN: Tolarian Terror — already had `KeywordAbilities::WARD` but no Ward ability; added `StaticEffect::ward("{2}")`
   120→
   121→**Tests added:** `static_effect_builders` extended with Ward variant checks
   122→
   123→---
   124→
   125→## Batch 6: Enters-tapped-unless (conditional ETB tapped) [DONE 2026-02-13]
   126→
   127→**Engine**: Added `StaticEffect::EntersTappedUnless { condition: String }` variant + `enters_tapped_unless()` builder. Condition is stored as structured data; mechanical enforcement (actually checking land types on ETB) deferred to future engine work.
   128→
   129→**Cards fixed (2):**
   130→- [x] TDM: Cori Mountain Monastery — `StaticEffect::Custom("Enters tapped unless you control Plains or Island.")` → `StaticEffect::enters_tapped_unless("you control a Plains or an Island")`
   131→- [x] TDM: Dalkovan Encampment — `StaticEffect::Custom("Enters tapped unless you control Swamp or Mountain.")` → `StaticEffect::enters_tapped_unless("you control a Swamp or a Mountain")`
   132→
   133→**Tests added:** `static_effect_builders` extended with EntersTappedUnless variant check
   134→
   135→**Note:** ECL Blood Crypt has a related but different pattern ("pay 2 life or enters tapped") — shockland mechanic, not a land-type check. Left as Custom for now.
   136→
   137→---
   138→
   139→## Batch 7: Mass keyword grant / mass boost until EOT [DONE 2026-02-13]
   140→
   141→**Engine**: Added `Effect::BoostAllUntilEndOfTurn { filter, power, toughness }` + `boost_all_eot()` constructor and `Effect::GrantKeywordAllUntilEndOfTurn { filter, keyword }` + `grant_keyword_all_eot()` constructor. Both implemented in `execute_effects()` with filter matching and "you control" controller check. Uses P1P1/M1M1 counters for boost (same simplification as single-target `BoostUntilEndOfTurn`). Keywords use `granted_keywords` which are cleared at EOT cleanup.
   142→
   143→**Cards fixed (8, 12 effect swaps):**
   144→- [x] FDN: Crash Through — `Custom` → `grant_keyword_all_eot("creatures you control", "trample")` + `draw_cards(1)`
   145→- [x] FDN: Overrun — 2× `Custom` → `boost_all_eot("creatures you control", 3, 3)` + `grant_keyword_all_eot("creatures you control", "trample")`
   146→- [x] FDN: Make a Stand — 2× `Custom` → `boost_all_eot("creatures you control", 1, 0)` + `grant_keyword_all_eot("creatures you control", "indestructible")`
   147→- [x] FDN: Heroic Reinforcements — 2× `Custom` → `boost_all_eot("creatures you control", 1, 1)` + `grant_keyword_all_eot("creatures you control", "haste")`
   148→- [x] FDN: Balmor, Battlemage Captain — `Custom` → `boost_all_eot("creatures you control", 1, 0)` + `grant_keyword_all_eot("creatures you control", "trample")`
   149→- [x] FDN: Claws Out — `Custom` → `boost_all_eot("creatures you control", 2, 2)`
   150→- [x] ECL: Timid Shieldbearer — `Custom` → `boost_all_eot("creatures you control", 1, 1)`
   151→- [x] ECL: Catharsis — `Custom` → `boost_all_eot("creatures you control", 1, 1)` + `grant_keyword_all_eot("creatures you control", "haste")`
   152→
   153→**Tests added:** `boost_all_and_grant_keyword_all_until_eot`
   154→
   155→**Skipped/Deferred:**
   156→- TDM: Craterhoof (variable +X/+X) — needs dynamic count support
   157→- ECL: Kithkin conditional ("+1/+0 + first strike for Kithkin only") — compound conditional filter
   158→- TDM: Modal spell with mass buff option — needs modal framework (Batch 11)
   159→
   160→---
   161→
   162→## Batch 8: Fight/Bite mechanic [DONE 2026-02-13]
   163→
   164→**Engine**: Added `Effect::Fight` (mutual damage) and `Effect::Bite` (one-way damage based on power) with proper two-target selection. Added `TargetSpec::Pair { CreatureYouControl, OpponentCreature }` and `TargetSpec::fight_targets()` builder for spell-based fight/bite. `select_targets_for_spec()` handles target selection by asking the decision maker. `resolve_fight_pair()` resolves fighter/target from explicit targets, source+target (ETB), or fallback auto-select. For compound effects (e.g. counter+bite), pre-fight/bite effects only apply to `targets[0]` (your creature), matching Java's per-effect target assignment.
   165→
   166→**Cards fixed (6):**
   167→- [x] FDN: Bite Down — `Custom` → `Effect::bite()` + `TargetSpec::fight_targets()`
   168→- [x] FDN: Affectionate Indrik — ETB `Custom` → `Effect::fight()` + `TargetSpec::OpponentCreature`
   169→- [x] FDN: Felling Blow — `Custom` → `Effect::add_p1p1_counters(1), Effect::bite()` + `TargetSpec::fight_targets()`
   170→- [x] ECL: Assert Perfection — `Custom` → `Effect::boost_until_eot(1, 0), Effect::bite()` + `TargetSpec::fight_targets()`
   171→- [x] TDM: Piercing Exhale — `Custom` → `Effect::bite()` + `TargetSpec::fight_targets()`

   176→**Skipped/Deferred:**
   177→- TDM: Dragonclaw Strike — "Double P/T then fight" — doubling not implementable
   178→- TDM: Dragon land (bite with Dragon-specific targeting) — custom target spec
   179→- FDN: Primal Might — X-cost + fight (Batch 15)

   186→## Batch 9: AddCountersAll (mass counter placement) [DONE 2026-02-13]
   187→
   188→**Engine**: Added `Effect::AddCountersAll { counter_type, count, filter }` variant + `add_counters_all()` constructor + match arm. Supports "you control" filter for controller-only targeting.
   189→
   190→**Cards fixed (2):**

   203→## Batch 10: Compound self-counter + target effects
   204→
   205→**Engine**: These cards need the ability to put counters on self AND apply a separate effect to a target in the same triggered/activated ability. The self-counter part now works (Batch 2 source fallback), but combining it with a target effect in one resolution needs verification.
   206→
   207→**Cards:**
   208→- [ ] ECL: Warren Torchmaster — begin combat: may blight 1 (self -1/-1 counter) to give target creature haste until EOT. Needs `add_counters("-1/-1", 1)` + `gain_keyword_eot("haste")` with target.
   209→- [ ] ECL: Dream Seizer — ETB: self -1/-1 counter + each opponent discards (also depends on Batch 3 OpponentDiscards)

Now I understand the problem. When `AddCounters` has targets from `TargetSpec::Creature`, it applies to the target creature, not self. I need to add an `Effect::AddCountersSelf` variant that always applies to the source permanent. Let me also check if there's a Java implementation of Warren Torchmaster.

Now I understand the full picture. The Java uses `BlightCost(1)` + reflexive trigger. In our engine, I need `Effect::AddCountersSelf` to keep the counter on self while `GainKeywordUntilEndOfTurn` targets the chosen creature.

Let me implement this. I'll work on:
1. Add `Effect::AddCountersSelf` variant + constructor + match arm
2. Add a test
3. Fix Warren Torchmaster
4. Mark Dream Seizer as already done (it was fixed in Batch 3)

Let me also search for other cards that might benefit from `AddCountersSelf`.

    11→**Recently implemented:** The following Effect variants were previously no-ops but now have working implementations in `execute_effects()`: `Scry`, `SearchLibrary`, `ReturnFromGraveyard`, `Reanimate`, `GainKeywordUntilEndOfTurn`, `GainKeyword`, `LoseKeyword`, `Indestructible`, `Hexproof`, `CantBlock`, `Sacrifice`, `DestroyAll`, `DealDamageAll`, `RemoveCounters`, `CreateTokenTappedAttacking`, `BoostPermanent`, `SetPowerToughness`, `LoseLifeOpponents`. Token stat parsing is also implemented (`CreateToken` now parses P/T and keywords from `token_name`).
    12→
    13→**Batch 2 engine change (2026-02-13):** Modified `execute_effects` to accept an optional `source: Option<ObjectId>` parameter. When `AddCounters` or `RemoveCounters` effects have no selected targets, they now fall back to the source permanent. This enables self-targeting counter effects (e.g., blight creatures putting -1/-1 counters on themselves) without requiring explicit target selection. Test: `add_counters_self_when_no_targets`.
    14→
    15→**Batch 5 (2026-02-13):** Added `StaticEffect::Ward { cost: String }` variant + `ward()` builder. Ward is a triggered ability that counters targeting spells/abilities unless the opponent pays the cost. The engine stores it as structured data (not yet mechanically enforced during targeting). Replaced `StaticEffect::Custom("Ward ...")` on 7 cards across FDN/TDM/ECL and added `KeywordAbilities::WARD` flags.
    16→
    17→**Batch 6 (2026-02-13):** Added `StaticEffect::EntersTappedUnless { condition: String }` variant + `enters_tapped_unless()` builder. Stored as structured data; mechanical enforcement deferred. Replaced `StaticEffect::Custom("Enters tapped unless ...")` on 2 TDM lands (Cori Mountain Monastery, Dalkovan Encampment).
    18→
    19→**Batch 7 (2026-02-13):** Added `Effect::BoostAllUntilEndOfTurn { filter, power, toughness }` and `Effect::GrantKeywordAllUntilEndOfTurn { filter, keyword }` variants with constructors and match arms. These mass-buff effects apply to all creatures matching the filter controlled by the effect's controller. Replaced Custom effects on 8 cards (6 FDN, 2 ECL) with 12 effect swaps total.
    20→
    21→**Batch 9 (2026-02-13):** Added `Effect::AddCountersAll { counter_type, count, filter }` variant + `add_counters_all()` constructor + match arm. Puts N counters of specified type on all creatures matching filter, with "you control" support. Fixed ECL Darkness Descends and partially fixed TDM Barrensteppe Siege (Abzan mode only).
    22→
    23→| Effect Variant | Description | Cards Blocked |
    24→|---------------|-------------|---------------|
    25→| `GainControl` | Gain control of target permanent | ~5 |
    26→| `GainControlUntilEndOfTurn` | Threaten/Act of Treason effects | ~5 |
    27→| `GainProtection` | Target gains protection from quality | ~5 |
    28→| `PreventCombatDamage` | Fog / damage prevention | ~5 |
    29→| `MustBlock` | Target creature must block | ~3 |
    30→| `SetLife` | Set a player's life total | ~2 |
    31→| `Custom(String)` | Catch-all for untyped effects | ~400+ |
    32→
    33→Note: `Custom(String)` is used when no typed variant exists. Each Custom needs to be individually replaced with a typed variant or a new variant added.
    34→
    35→### Missing Engine Systems
    36→
    37→These are features that require new engine architecture, not just new match arms:
    38→
    39→#### Equipment System
    40→- No attach/detach mechanics
    41→- Equipment stat bonuses not applied
    42→- Equip cost not evaluated
    43→- **Blocked cards:** Basilisk Collar, Swiftfoot Boots, Goldvein Pick, Fishing Pole, all Equipment (~15+ cards)
    44→
    45→#### Planeswalker System
    46→- Loyalty counters not tracked as a resource
    47→- Planeswalker abilities not resolved (loyalty cost/gain)
    48→- Planeswalker damage redirection not enforced
    49→- **Blocked cards:** Ajani, Chandra, Kaito, Liliana, Vivien, all planeswalkers (~10+ cards)
    50→
    51→#### Modal Spells
    52→- No mode selection framework
    53→- `choose_mode()` decision interface exists but is unused
    54→- **Blocked cards:** Abrade, Boros Charm, Slagstorm, Valorous Stance, Coordinated Maneuver, Frontline Rush, Sarkhan's Resolve, Seize Opportunity (~20+ cards)
    55→
    56→#### X-Cost Spells
    57→- No variable cost determination
    58→- X is not tracked or passed to effects
    59→- **Blocked cards:** Day of Black Sun, Spectral Denial (partially works), Genesis Wave, Finale of Revelation (~10+ cards)
    60→
    61→#### ~~Fight/Bite Mechanic~~ (DONE)
    62→`Effect::Fight` (mutual damage) and `Effect::Bite` (one-way damage) implemented with proper two-target selection via `TargetSpec::Pair { CreatureYouControl, OpponentCreature }`. Matches Java's `FightTargetsEffect` / `DamageWithPowerFromOneToAnotherTargetEffect` pattern. Compound effects (e.g. +1/+1 counter then bite) correctly apply pre-fight/bite effects only to `targets[0]` (your creature). Fixed 6 cards (Bite Down, Affectionate Indrik, Felling Blow, Knockout Maneuver, Piercing Exhale, Assert Perfection). ETB triggers (Affectionate Indrik) use `TargetSpec::OpponentCreature` with source as fighter. Remaining fight/bite cards blocked by modal spells (Batch 11), X-cost (Batch 15), or other missing systems.
    63→
    64→#### ~~Token Stat Parsing~~ (DONE)
    65→`CreateToken` now parses P/T and keywords from `token_name` strings (e.g., '4/4 Dragon with flying' creates a 4/4 with flying). Cards using correctly-formatted token names now work.
    66→
    67→#### Aura/Enchant System
    68→- Auras exist as permanents but don't attach to creatures
    69→- Static P/T boosts from Auras not applied
    70→- Keyword grants from Auras not applied
    71→- **Blocked cards:** Pacifism (partially works via CantAttack/CantBlock), Obsessive Pursuit, Eaten by Piranhas, Angelic Destiny (~10+ cards)
    72→
    73→#### Impulse Draw (Exile-and-Play)
    74→- "Exile top card, you may play it until end of [next] turn" has no implementation
    75→- **Blocked cards:** Equilibrium Adept, Kulrath Zealot, Sizzling Changeling, Burning Curiosity, Etali (~10+ cards)
    76→
    77→#### Spell Copy
    78→- No mechanism to copy spells on the stack
    79→- **Blocked cards:** Electroduplicate, Rite of Replication, Self-Reflection, Flamehold Grappler, Sage of the Skies (~8+ cards)
    80→
    81→#### Replacement Effects
    82→- `ReplacementEffect` struct exists in `effects.rs` but is not integrated into the event pipeline
    83→- Events are not interceptable before they resolve
    84→- **Blocked features:** "If a creature would die, exile it instead", "If you would gain life, gain that much +1", Doubling Season, damage prevention, Dryad Militant graveyard replacement
    85→
    86→#### Additional Combat Phases
    87→- No support for extra combat steps
    88→- **Blocked cards:** Aurelia the Warleader, All-Out Assault (~3 cards)
    89→
    90→#### "Behold" Mechanic (ECL-specific)
    91→- Reveal-and-exile-from-hand mechanic not implemented
    92→- Many ECL cards reference it as an alternative cost or condition
    93→- **Blocked cards:** Champion of the Weird, Champions of the Perfect, Molten Exhale, Osseous Exhale (~15+ cards)
    94→
    95→#### "Earthbend" Mechanic (TLA-specific)
    96→- "Look at top N, put a land to hand, rest on bottom" not implemented
    97→- **Blocked cards:** Badgermole, Badgermole Cub, Ostrich-Horse, Dai Li Agents, Earth Kingdom General, Earth Village Ruffians, many TLA cards (~20+ cards)
    98→
    99→#### "Vivid" Mechanic (ECL-specific)
   100→- "X = number of colors among permanents you control" calculation not implemented
   101→- **Blocked cards:** Explosive Prodigy, Glister Bairn, Luminollusk, Prismabasher, Shimmercreep, Shinestriker, Squawkroaster (~10+ cards)
   102→
   103→#### Delayed Triggers
   104→- "When this creature dies this turn, draw a card" style effects
   105→- No framework for registering one-shot triggered abilities
   106→- **Blocked cards:** Undying Malice, Fake Your Own Death, Desperate Measures, Scarblades Malice (~5+ cards)
   107→
   108→#### Conditional Cost Modifications
   109→- `CostReduction` static effect exists but may not apply correctly
   110→- No support for "second spell costs {1} less" or Affinity
   111→- **Blocked cards:** Highspire Bell-Ringer, Allies at Last, Ghalta Primal Hunger (~5+ cards)
   112→
   113→---
   114→
   115→## Phased Implementation Plan
   116→
   117→### Phase 1: High-Impact Engine Effects
   118→
   119→These unblock the most cards per effort invested.
   120→
   121→1. **Token stat parsing** -- **DONE** -- Parse power/toughness/keywords from `token_name` string in `CreateToken`. Unblocks ~30 cards that already create tokens but with wrong stats.
   122→
   123→2. **Fix easy card-level bugs** -- Many cards use `Effect::Custom(...)` when a typed variant already exists. Examples:
   124→   - ~~Phyrexian Arena: `Custom("You lose 1 life.")` -> `LoseLife { amount: 1 }`~~ **DONE**
   125→   - ~~Pulse Tracker/Marauding Blight-Priest/Vampire Spawn/Vampire Neonate: `Custom("Each opponent loses N life")` -> `LoseLifeOpponents { amount: N }`~~ **DONE**
   126→   - ~~Skirmish Rhino (TDM), Champion of the Weird (ECL), Boggart Mischief (ECL): opponent life loss Custom -> `LoseLifeOpponents`~~ **DONE**
   127→   - ~~Diregraf Ghoul: `StaticEffect::Custom("Enters tapped.")` -> `StaticEffect::EntersTapped`~~ **DONE**
   128→   - Incomplete dual lands: copy the Azorius Guildgate / Bloodfell Caves pattern
   129→   - ~~Sourbread Auntie/Sting-Slinger/Blighted Blackthorn: self-counter Custom -> `AddCounters` targeting self~~ **DONE**
   130→   - ~~Day of Judgment: `Custom("Destroy all creatures.")` -> `DestroyAll`~~ **DONE**
   131→   - ~~Frenzied Goblin/Brambleback Brute: `Custom("can't block")` -> `CantBlock`~~ **DONE**
   132→   - ~~Icewind Elemental/Refute: loot/counter Custom -> typed effects~~ **DONE**
   133→   - ~~ECL RemoveCounters cards (Encumbered Reejerey, Reluctant Dounguard, Heirloom Auntie, Bristlebane Battler): Custom -> `RemoveCounters` with source fallback~~ **DONE**
   134→   - ~~Mistmeadow Council: Custom -> `draw_cards(1)`~~ **DONE**
   135→   - ~~Guarded Heir, Prideful Parent, Resolute Reinforcements, Release the Dogs, Dwynen's Elite, Dragonmaster Outcast, Searslicer Goblin: token creation Custom -> `create_token()`~~ **DONE**
   136→   - ~~Clachan Festival (ECL): token creation Custom + Cost::Custom -> `create_token()` + `Cost::pay_mana()`~~ **DONE**
   137→   - ~~Burglar Rat/Dream Seizer/Arbiter of Woe/Bloodtithe Collector: opponent discard Custom -> `DiscardOpponents { count }`~~ **DONE**
   138→
   139→3. ~~**Fight mechanic** -- New `Effect::Fight` and `Effect::Bite` variants. Fight = mutual damage, Bite = one-way. Fixed 6 cards.~~ **PARTIAL** — auto-selects strongest creature instead of player choice (needs multi-target `TargetSpec`). ETB triggers correct; spell-based is heuristic.
   140→
   141→### Phase 2: Key Missing Mechanics
   142→
   143→4. **Equipment system** -- Attach/detach, equip cost, stat/keyword application. Unblocks ~15 cards.
   144→
   145→5. **Modal spells** -- Mode selection in `PlayerDecisionMaker` trait, mode-conditional effect resolution. Unblocks ~20 cards.
   146→
   147→6. **Impulse draw** -- "Exile top N, may play until end of [next] turn." Track exiled-playable cards in game state. Unblocks ~10 cards.
   148→
   149→7. **Earthbend** (TLA-specific) -- "Look at top N, put a land to hand, rest on bottom." Unblocks ~20 TLA cards.
   150→
   151→### Phase 3: Advanced Systems
   152→
   153→8. **Replacement effects** -- Event interception pipeline. Required for damage prevention, death replacement, Doubling Season, "exile instead of dying."
   154→
   155→9. **X-cost spells** -- Variable cost determination + passing X to effects.
   156→
   157→10. **Aura attachment** -- Auras attach to targets, apply continuous effects while attached.
   158→
   159→11. **Spell copy** -- Clone spells on the stack with new targets.
   160→
   161→12. **Planeswalker system** -- Loyalty as a resource, planeswalker abilities, damage redirection.
   162→
   163→13. **Additional combat phases** -- Extra attack steps.
   164→
   165→### Phase 4: Set-Specific Mechanics
   166→
   167→14. **Behold** (ECL) -- Reveal-from-hand alternative cost/condition.
   168→15. **Vivid** (ECL) -- Color-count calculation for dynamic X values.
   169→16. **Learn** (TLA) -- May discard to draw keyword action.
   170→17. **Renew** (TDM) -- Counter-based death replacement.
   171→18. **Mobilize** (TDM) -- Create N 1/1 Soldier tokens. (Partially works via `CreateToken` already.)
   172→
   173→---
   174→
   175→## Per-Set Status

```

## Assistant

**Batch 10 complete.** Here's the summary:

**Engine change:** Added `Effect::AddCountersSelf { counter_type, count }` variant + `add_counters_self()` constructor + match arm in `execute_effects`. Unlike `AddCounters` (which falls back to source only when targets are empty), `AddCountersSelf` always applies counters to the source permanent regardless of other targets. This enables compound effects where one part targets self and another targets a chosen creature.

**Cards fixed (1):**
- **Warren Torchmaster** (ECL) — `Effect::Custom(...)` → `add_counters_self("-1/-1", 1)` + `gain_keyword_eot("haste")` with `TargetSpec::Creature` + `.set_optional()`. Matches the Java implementation's `BlightCost(1)` + `ReflexiveTriggeredAbility` pattern.
- **Dream Seizer** was already fixed in Batch 3 (noted in queue as already done).

**Test added:** `add_counters_self_with_separate_target` — verifies that in a compound effect, `AddCountersSelf` puts -1/-1 on the source while `GainKeywordUntilEndOfTurn` grants haste to the target, with neither effect bleeding to the wrong permanent.

**All 255 tests passing.**

 These `Effect` enum variants exist in `abilities.rs` but have no implementation in `execute_effects()` -- they fall through to `_ => {}` and silently do nothing at runtime.
 
-**Recently implemented:** The following Effect variants were previously no-ops but now have working implementations in `execute_effects()`: `Scry`, `SearchLibrary`, `ReturnFromGraveyard`, `Reanimate`, `GainKeywordUntilEndOfTurn`, `GainKeyword`, `LoseKeyword`, `Indestructible`, `Hexproof`, `CantBlock`, `Sacrifice`, `DestroyAll`, `DealDamageAll`, `RemoveCounters`, `CreateTokenTappedAttacking`, `BoostPermanent`, `SetPowerToughness`.

    41→- [x] ECL: Brambleback Brute — `Effect::Custom("Target creature can't block this turn.")` → `Effect::CantBlock`
    42→- **Note**: The work queue originally listed "Skoa Veteran" for batch 2c, but the actual card in ecl.rs was **Brambleback Brute**.
    43→- Verify: these cards already have `TargetSpec::OpponentCreature` or similar targeting
    44→
    45→### 2d: Self -1/-1 counters — ECL blight creatures
    46→These use `Effect::Custom("Put N -1/-1 counter(s) on <self>.")` alongside working effects. Replace with `Effect::AddCounters`:
    47→- [x] ECL: Blighted Blackthorn (x2) — `Custom("Put two -1/-1 counters on Blighted Blackthorn.")` → `Effect::add_counters("-1/-1", 2)` (appears twice, two abilities)
    48→- [x] ECL: Sourbread Auntie — `Custom("Put two -1/-1 counters on Sourbread Auntie.")` → `Effect::add_counters("-1/-1", 2)`
    49→- [x] ECL: Sting-Slinger — `Custom("Put a -1/-1 counter on Sting-Slinger.")` → `Effect::add_counters("-1/-1", 1)`
    50→- [x] ECL: Heirloom Auntie — `Custom("Remove a -1/-1 counter from Heirloom Auntie.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    51→- [x] ECL: Encumbered Reejerey — `Custom("Remove a -1/-1 counter from Encumbered Reejerey.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    52→- [x] ECL: Reluctant Dounguard — `Custom("Remove a -1/-1 counter from Reluctant Dounguard.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    53→- [x] ECL: Bristlebane Battler — `Custom("Remove a -1/-1 counter from this creature.")` → `Effect::RemoveCounters { counter_type: "-1/-1", count: 1 }`
    54→- **Engine tweak**: `execute_effects` now falls back to the source permanent when `AddCounters`/`RemoveCounters` have no targets (self-targeting counter effects).
    55→
    56→### 2e: Loot (draw then discard) — Icewind Elemental, Refute
    57→- [x] FDN: Icewind Elemental — `Custom("When this creature enters, draw a card, then discard a card.")` → `Effect::draw_cards(1), Effect::discard_cards(1)`
    58→- [x] FDN: Refute — `Custom("Counter target spell. Draw a card, then discard a card.")` → `Effect::counter_spell(), Effect::draw_cards(1), Effect::discard_cards(1)` + fixed TargetSpec to Spell
    59→
    60→### 2f: Simple ETB draw — Mistmeadow Council
    61→- [x] ECL: Mistmeadow Council — `Custom("When this creature enters, draw a card.")` → `Effect::draw_cards(1)`
    62→
    63→### Cards NOT fixed in Batch 2 (deferred):
    64→- **Warren Torchmaster** (ECL): compound Custom with self-counter + target haste (needs modal/conditional support)
    65→- **Dream Seizer** (ECL): compound Custom with self-counter + opponent discard (Batch 3 dependency)
    66→- **ECL line ~1843**: "Put two -1/-1 counters on each creature." — needs `AddCountersAll` variant (new engine effect)
    67→- **ECL line ~464**: `Cost::Custom` for -1/-1 counter removal — not an Effect, needs Cost system fix
    68→
    69→---
    70→
    71→## Batch 3: OpponentDiscards [DONE 2026-02-13]
    72→
    73→**Engine**: Added `Effect::DiscardOpponents { count }` variant + `discard_opponents(count)` constructor + match arm in `execute_effects` (iterates opponents, each calls `choose_discard` then moves to graveyard). Added test `discard_opponents_effect`.
    74→
    75→**Cards fixed (4):**
    76→- [x] FDN: Burglar Rat — `Custom("Each opponent discards a card.")` → `Effect::discard_opponents(1)`
    77→- [x] FDN: Arbiter of Woe — compound Custom → `discard_opponents(1), lose_life_opponents(2), draw_cards(1), gain_life(2)`
    78→- [x] FDN: Bloodtithe Collector — `Custom(conditional)` → `Effect::discard_opponents(1)` (condition "if an opponent lost life this turn" not modeled; trigger fires unconditionally)
    79→- [x] ECL: Dream Seizer — `Custom(compound)` → `add_counters("-1/-1", 1), discard_opponents(1)` (self-counter via Batch 2 source fallback)
    80→
    81→---
    82→
    83→## Batch 4: Simple token creation [DONE 2026-02-13]
    84→
    85→**Engine**: No changes needed. `CreateToken` already works and parses P/T + keywords from `token_name`.
    86→
    87→**Cards fixed (8 cards, 10 effect swaps):**
    88→- [x] FDN: Guarded Heir — ETB `create_token("3/3 Knight", 2)`
    89→- [x] FDN: Prideful Parent — ETB `create_token("1/1 Cat", 1)`
    90→- [x] FDN: Resolute Reinforcements — ETB `create_token("1/1 Soldier", 1)`
    91→- [x] FDN: Release the Dogs — Spell `create_token("1/1 Dog", 4)`
    92→- [x] FDN: Dwynen's Elite — ETB `create_token("1/1 Elf Warrior", 1)` (conditional "if you control another Elf" not modeled)
    93→- [x] FDN: Dragonmaster Outcast — Upkeep `create_token("5/5 Dragon with flying", 1)` (conditional "six or more lands" not modeled)
    94→- [x] FDN: Searslicer Goblin — End step `create_token("1/1 Goblin", 1)` (raid condition not modeled)
    95→- [x] ECL: Clachan Festival — ETB `create_token("1/1 Kithkin", 2)` + Activated `Cost::pay_mana("{4}{W}")` + `create_token("1/1 Kithkin", 1)`
    96→
    97→**Tests added:** `framework_create_token_effect`, `framework_create_token_with_keyword`
    98→
    99→**Skipped/Deferred:**
   100→- FDN: Cat Collector (Food token) — Food tokens are artifacts, not creatures. `CreateToken` always sets `CardType::Creature`. Needs engine support for artifact tokens (new batch).
   101→- FDN: Faebloom Trick — compound effect: create 2 Faerie tokens + reflexive trigger (tap opponent creature). Needs multi-effect resolution.
   102→- FDN: Mender's Bounty (Food token) — same as Cat Collector.
   103→- All token copy effects (Electroduplicate, Rite of Replication, etc.) — needs Spell Copy system.
   104→- All variable-count tokens (Homunculus Horde, Hare Apparent, etc.) — needs dynamic count support.
   105→
   106→---
   107→
   108→## Batch 5: Ward keyword [DONE 2026-02-13]
   109→
   110→**Engine**: Added `StaticEffect::Ward { cost: String }` variant + `ward()` builder. Ward is stored as structured data; mechanical enforcement (counter-unless-pay during targeting) deferred to future engine work. `KeywordAbilities::WARD` already existed in bitflags.
   111→
   112→**Cards fixed (7):**
   113→- [x] TDM: Aegis Sculptor — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   114→- [x] TDM: Ambling Stormshell — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   115→- [x] TDM: Dirgur Island Dragon — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   116→- [x] TDM: Scavenger Regent — `StaticEffect::Custom("Ward -- Discard a card.")` → `StaticEffect::ward("Discard a card.")` + WARD keyword
   117→- [x] ECL: Bristlebane Battler — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   118→- [x] FDN: Cackling Prowler — `StaticEffect::Custom("Ward {2}")` → `StaticEffect::ward("{2}")` + WARD keyword
   119→- [x] FDN: Tolarian Terror — already had `KeywordAbilities::WARD` but no Ward ability; added `StaticEffect::ward("{2}")`
   120→
   121→**Tests added:** `static_effect_builders` extended with Ward variant checks
   122→
   123→---
   124→
   125→## Batch 6: Enters-tapped-unless (conditional ETB tapped) [DONE 2026-02-13]
   126→
   127→**Engine**: Added `StaticEffect::EntersTappedUnless { condition: String }` variant + `enters_tapped_unless()` builder. Condition is stored as structured data; mechanical enforcement (actually checking land types on ETB) deferred to future engine work.
   128→
   129→**Cards fixed (2):**
   130→- [x] TDM: Cori Mountain Monastery — `StaticEffect::Custom("Enters tapped unless you control Plains or Island.")` → `StaticEffect::enters_tapped_unless("you control a Plains or an Island")`
   131→- [x] TDM: Dalkovan Encampment — `StaticEffect::Custom("Enters tapped unless you control Swamp or Mountain.")` → `StaticEffect::enters_tapped_unless("you control a Swamp or a Mountain")`
   132→
   133→**Tests added:** `static_effect_builders` extended with EntersTappedUnless variant check
   134→
   135→**Note:** ECL Blood Crypt has a related but different pattern ("pay 2 life or enters tapped") — shockland mechanic, not a land-type check. Left as Custom for now.
   136→
   137→---
   138→
   139→## Batch 7: Mass keyword grant / mass boost until EOT [DONE 2026-02-13]
   140→
   141→**Engine**: Added `Effect::BoostAllUntilEndOfTurn { filter, power, toughness }` + `boost_all_eot()` constructor and `Effect::GrantKeywordAllUntilEndOfTurn { filter, keyword }` + `grant_keyword_all_eot()` constructor. Both implemented in `execute_effects()` with filter matching and "you control" controller check. Uses P1P1/M1M1 counters for boost (same simplification as single-target `BoostUntilEndOfTurn`). Keywords use `granted_keywords` which are cleared at EOT cleanup.
   142→
   143→**Cards fixed (8, 12 effect swaps):**
   144→- [x] FDN: Crash Through — `Custom` → `grant_keyword_all_eot("creatures you control", "trample")` + `draw_cards(1)`
   145→- [x] FDN: Overrun — 2× `Custom` → `boost_all_eot("creatures you control", 3, 3)` + `grant_keyword_all_eot("creatures you control", "trample")`
   146→- [x] FDN: Make a Stand — 2× `Custom` → `boost_all_eot("creatures you control", 1, 0)` + `grant_keyword_all_eot("creatures you control", "indestructible")`
   147→- [x] FDN: Heroic Reinforcements — 2× `Custom` → `boost_all_eot("creatures you control", 1, 1)` + `grant_keyword_all_eot("creatures you control", "haste")`
   148→- [x] FDN: Balmor, Battlemage Captain — `Custom` → `boost_all_eot("creatures you control", 1, 0)` + `grant_keyword_all_eot("creatures you control", "trample")`
   149→- [x] FDN: Claws Out — `Custom` → `boost_all_eot("creatures you control", 2, 2)`
   150→- [x] ECL: Timid Shieldbearer — `Custom` → `boost_all_eot("creatures you control", 1, 1)`
   151→- [x] ECL: Catharsis — `Custom` → `boost_all_eot("creatures you control", 1, 1)` + `grant_keyword_all_eot("creatures you control", "haste")`
   152→
   153→**Tests added:** `boost_all_and_grant_keyword_all_until_eot`
   154→
   155→**Skipped/Deferred:**
   156→- TDM: Craterhoof (variable +X/+X) — needs dynamic count support
   157→- ECL: Kithkin conditional ("+1/+0 + first strike for Kithkin only") — compound conditional filter
   158→- TDM: Modal spell with mass buff option — needs modal framework (Batch 11)
   159→
   160→---
   161→
   162→## Batch 8: Fight/Bite mechanic [DONE 2026-02-13]
   163→
   164→**Engine**: Added `Effect::Fight` (mutual damage) and `Effect::Bite` (one-way damage based on power) with proper two-target selection. Added `TargetSpec::Pair { CreatureYouControl, OpponentCreature }` and `TargetSpec::fight_targets()` builder for spell-based fight/bite. `select_targets_for_spec()` handles target selection by asking the decision maker. `resolve_fight_pair()` resolves fighter/target from explicit targets, source+target (ETB), or fallback auto-select. For compound effects (e.g. counter+bite), pre-fight/bite effects only apply to `targets[0]` (your creature), matching Java's per-effect target assignment.
   165→
   166→**Cards fixed (6):**
   167→- [x] FDN: Bite Down — `Custom` → `Effect::bite()` + `TargetSpec::fight_targets()`
   168→- [x] FDN: Affectionate Indrik — ETB `Custom` → `Effect::fight()` + `TargetSpec::OpponentCreature`
   169→- [x] FDN: Felling Blow — `Custom` → `Effect::add_p1p1_counters(1), Effect::bite()` + `TargetSpec::fight_targets()`
   170→- [x] ECL: Assert Perfection — `Custom` → `Effect::boost_until_eot(1, 0), Effect::bite()` + `TargetSpec::fight_targets()`
   171→- [x] TDM: Piercing Exhale — `Custom` → `Effect::bite()` + `TargetSpec::fight_targets()`
   172→- [x] TDM: Knockout Maneuver — `Custom` → `Effect::add_p1p1_counters(1), Effect::bite()` + `TargetSpec::fight_targets()`
   173→
   174→**Tests added:** `fight_and_bite_effects`, `fight_auto_selects_creatures`, `compound_bite_counters_only_on_your_creature`
   175→
   176→**Skipped/Deferred:**
   177→- TDM: Dragonclaw Strike — "Double P/T then fight" — doubling not implementable
   178→- TDM: Dragon land (bite with Dragon-specific targeting) — custom target spec
   179→- FDN: Primal Might — X-cost + fight (Batch 15)
   180→- FDN: Tyvar's Stand (Choose one with fight) — modal (Batch 11)
   181→- ECL: Kithkin Whirlwind (Choose two with fight) — modal (Batch 11)
   182→- TLA: Earth Rumble — stub with no abilities defined
   183→
   184→---
   185→
   186→## Batch 9: AddCountersAll (mass counter placement) [DONE 2026-02-13]
   187→
   188→**Engine**: Added `Effect::AddCountersAll { counter_type, count, filter }` variant + `add_counters_all()` constructor + match arm. Supports "you control" filter for controller-only targeting.
   189→
   190→**Cards fixed (2):**
   191→- [x] ECL: Darkness Descends — `Custom("Put two -1/-1 counters on each creature.")` → `Effect::add_counters_all("-1/-1", 2, "creatures")`
   192→- [x] TDM: Barrensteppe Siege (Abzan mode only) — `Custom("Put +1/+1 counter on each creature you control.")` → `Effect::add_counters_all("+1/+1", 1, "creatures you control")`
   193→
   194→**Tests added:** `add_counters_all_effect`
   195→
   196→**Skipped/Deferred:**
   197→- TDM: Felothar — compound: sacrifice + then put +1/+1 counter on each creature (reflexive trigger)
   198→- TDM: Barrensteppe Siege (Mardu mode) — "each opponent sacrifices a creature" (different effect)
   199→- TDM: Barrensteppe Siege (ETB) — modal choice not modeled
   200→
   201→---
   202→
   203→## Batch 10: Compound self-counter + target effects [DONE 2026-02-14]
   204→
   205→**Engine**: Added `Effect::AddCountersSelf { counter_type, count }` variant + `add_counters_self()` constructor + match arm. Unlike `AddCounters` (which falls back to source only when targets are empty), `AddCountersSelf` always applies to the source permanent regardless of other targets. This enables compound effects where one effect targets self and another targets a chosen creature (e.g. blight self + grant haste to target).
   206→
   207→**Cards fixed (1):**
   208→- [x] ECL: Warren Torchmaster — `Custom("Put a -1/-1 counter ... Target creature gains haste ...")` → `add_counters_self("-1/-1", 1)` + `gain_keyword_eot("haste")` with `TargetSpec::Creature` + `.set_optional()`
   209→- [x] ECL: Dream Seizer — already fixed in Batch 3 (`add_counters("-1/-1", 1)` + `discard_opponents(1)`, no separate target needed since both effects are self/global)
   210→
   211→**Tests added:** `add_counters_self_with_separate_target`
   212→
   213→---
   214→
   215→## Batch 11: Modal spells (Choose one/two)
   216→
   217→**Engine**: Modal framework — player chooses mode, effects resolve based on mode selection.
   218→
   219→**Cards (~15+):**
   220→- [ ] FDN: Abrade, Boros Charm, Slagstorm, Valorous Stance, Charming Prince
   221→- [ ] TDM: multiple
   222→- [ ] ECL: multiple
   223→
   224→---
   225→
   226→## Batch 12+: Larger systems
   227→
   228→These require more significant engine work:
   229→- Equipment attach/detach (Batch 12)
   230→- Planeswalker loyalty (Batch 13)
   231→- Token copy (Batch 14)
   232→- X-cost spells (Batch 15)
   233→- Aura attachment (Batch 16)
   234→- Impulse draw / exile-and-play (Batch 17)
   235→- Sagas / lore counters (Batch 18)
   236→- Set mechanics: Earthbend (TLA), Blight (ECL), Vivid (ECL), Behold (ECL) (Batch 19+)
   237→- Cost system: `Cost::Custom` for counter removal (ECL line ~464), `Cost::RemoveCounters`, `Cost::ExileFromGraveyard`
   238→

   240→
   241→## How to pick the next batch
   242→
   243→1. Always do the lowest-numbered unchecked batch first
   244→2. If a batch has a NOTE about engine uncertainty, investigate before committing
   245→3. After finishing a batch, update this file AND the per-set remediation docs

     4→- Total cards: 230 (excluding basic lands)
     5→- Complete: 56
     6→- Partial: 69

     8→- Missing: 0
     9→
    10→## How to Fix Cards
    11→
    12→### Engine Context
    13→The Rust MTG engine is structured as a Cargo workspace with these key crates:
    14→
    15→- **mtg-engine** (`mtg-engine/src/`) — Core game logic
    16→  - `game.rs` — Game loop and `execute_effects()` dispatcher
    17→  - `abilities.rs` — `Effect`, `StaticEffect`, `Cost`, `Ability`, `TargetSpec` enums and constructors
    18→  - `effects.rs` — `StaticEffect` variant definitions
    19→  - `constants.rs` — `CardType`, `SubType`, `KeywordAbilities`, `Rarity`, etc.
    20→  - `events.rs` — `EventType` enum for triggers
    21→- **mtg-cards** (`mtg-cards/src/`) — Card definitions
    22→  - `sets/ecl.rs` — All ECL card factory functions
    23→  - `registry.rs` — `CardRegistry` for name-to-factory mapping
    24→
    25→### Working Effects (handled in `execute_effects()`)
    26→These `Effect` variants have actual implementations in the game engine:
    27→- `Effect::DealDamage { amount }` / `deal_damage(n)`
    28→- `Effect::Destroy` / `destroy()`
    29→- `Effect::Exile` / `exile()`
    30→- `Effect::Bounce` / `bounce()` (return to hand)
    31→- `Effect::DrawCards { count }` / `draw_cards(n)`
    32→- `Effect::GainLife { amount }` / `gain_life(n)`
    33→- `Effect::LoseLife { amount }` / `lose_life(n)`
    34→- `Effect::DealDamageOpponents { amount }` / `damage_opponents(n)`
    35→- `Effect::AddCounters { counter_type, count }` / `add_counters(type, n)`
    36→- `Effect::BoostUntilEndOfTurn { power, toughness }` / `boost_until_eot(p, t)`
    37→- `Effect::TapTarget` / (via tap effects)
    38→- `Effect::UntapTarget` / (via untap effects)
    39→- `Effect::CounterSpell` / `counter_spell()`
    40→- `Effect::AddMana { mana }` / (via mana abilities)
    41→- `Effect::DiscardCards { count }` / `discard_cards(n)`
    42→- `Effect::Mill { count }` / `mill(n)`
    43→- `Effect::CreateToken { token_name, count }` / `create_token(name, n)` — now parses P/T and keywords from token_name
    44→- `Effect::Scry { count }` / `scry(n)`
    45→- `Effect::SearchLibrary { filter }` / `search_library(filter)`
    46→- `Effect::ReturnFromGraveyard` / `return_from_graveyard()`
    47→- `Effect::Reanimate` / `reanimate()`
    48→- `Effect::GainKeywordUntilEndOfTurn { keyword }` / `gain_keyword_eot(kw)`
    49→- `Effect::GainKeyword { keyword }` / `gain_keyword(kw)`
    50→- `Effect::LoseKeyword { keyword }` / `lose_keyword(kw)`
    51→- `Effect::Indestructible` / `indestructible()`
    52→- `Effect::Hexproof` / `hexproof()`
    53→- `Effect::CantBlock` / `cant_block()`
    54→- `Effect::Sacrifice { filter }` / `sacrifice(filter)`
    55→- `Effect::DestroyAll { filter }` / `destroy_all(filter)`
    56→- `Effect::DealDamageAll { amount, filter }` / `deal_damage_all(n, filter)`
    57→- `Effect::RemoveCounters { counter_type, count }` / `remove_counters(type, n)`
    58→- `Effect::CreateTokenTappedAttacking { token_name, count }` / `create_token_tapped_attacking(name, n)`
    59→- `Effect::BoostPermanent { power, toughness }` / `boost_permanent(p, t)`
    60→- `Effect::SetPowerToughness { power, toughness }` / `set_power_toughness(p, t)`
    61→
    62→### Non-functional Effects (NO-OP at runtime)
    63→These fall through to `_ => {}` in `execute_effects()`:
    64→- `Effect::SetLife` — Set life total
    65→- `Effect::MustBlock` — Force blocking
    66→- `Effect::PreventCombatDamage` — Prevent damage
    67→- `Effect::GainControl` / `GainControlUntilEndOfTurn` — Steal
    68→- `Effect::GainProtection` — Protection
    69→- `Effect::Custom(...)` — always a no-op
    70→- `StaticEffect::Custom(...)` — non-functional in continuous effects system
    71→
    72→### Adding a New Effect Type
    73→1. Add the variant to the `Effect` enum in `mtg-engine/src/abilities.rs`
    74→2. Add a convenience constructor (e.g., `pub fn my_effect() -> Self { Effect::MyEffect }`)
    75→3. Handle the variant in the `execute_effects()` match in `mtg-engine/src/game.rs`
    76→4. Update card code in `mtg-cards/src/sets/ecl.rs` to use the new typed variant instead of `Effect::Custom`
    77→
    78→---
    79→
    80→## Complete Cards
    81→These cards use only working typed effects and will function correctly in gameplay.

   930→## Priority Fixes (Highest Impact)
   931→
   932→### ~~1. Implement `GainKeywordUntilEndOfTurn` in execute_effects()~~ DONE
   933→~~Unblocks: Burdened Stoneback, Flame-Chain Mauler, Iron-Shield Elf, Kulrath Mystic, Scarblades Malice, Stratosoarer, and many more.~~
   934→Now implemented. Cards using `gain_keyword_eot()` are functional.
   935→
   936→### ~~2. Implement `Scry`/`Surveil` in execute_effects()~~ DONE
   937→~~Unblocks: Lys Alana Informant, Shore Lurker, Unwelcome Sprite, Heirloom Auntie, Dawnhand Dissident, Morcant's Eyes.~~
   938→Now implemented. Surveil approximated as scry.
   939→
   940→### ~~3. Update cards using `Effect::Custom` for `RemoveCounters`~~ MOSTLY DONE
   941→The `RemoveCounters` effect is implemented, and the engine now falls back to source permanent when no targets are present.
   942→~~Cards needing card-code updates: Encumbered Reejerey, Reluctant Dounguard, Heirloom Auntie, Bristlebane Battler~~ -- **DONE** (Batch 2).
   943→Cards still needing updates: Creakwood Safewright, Slumbering Walker.
   944→
   945→### ~~4. Implement `ReturnFromGraveyard` and `Reanimate` in execute_effects()~~ DONE
   946→~~Unblocks: Dundoolin Weaver, Graveshifter, Midnight Tilling, Dose of Dawnglow, Emptiness, Bre of Clan Stoutarm, Dawn-Blessed Pennant.~~
   947→Now implemented. Cards using `return_from_graveyard()` and `reanimate()` are functional.
   948→
   949→### ~~5. Implement `SearchLibrary` in execute_effects()~~ DONE
   950→~~Unblocks: Changeling Wayfinder, Kulrath Zealot, Celestial Reunion, Tend the Sprigs.~~
   951→Now implemented. Cards using `search_library(filter)` are functional.
   952→
   953→### 6. Implement Vivid mechanic (count colors among permanents)
   954→Unblocks: Explosive Prodigy, Glister Bairn, Luminollusk, Prismabasher, Shimmercreep, Shinestriker, Squawkroaster, Rime Chill.
   955→
   956→### ~~7. Fix easy Custom-to-typed replacements~~ DONE (Batch 2)
   957→~~Several cards use `Effect::Custom` for effects that already have typed variants:~~
   958→- ~~Mistmeadow Council: replace Custom with `draw_cards(1)`~~ **DONE**
   959→- ~~Sourbread Auntie: replace Custom blight with `add_counters("-1/-1", 2)` (targeting self)~~ **DONE**
   960→- ~~Blighted Blackthorn: same self-counter replacement~~ **DONE**
   961→- ~~Sting-Slinger: same self-counter replacement~~ **DONE**
   962→- ~~Encumbered Reejerey: replace Custom with `remove_counters("-1/-1", 1)`~~ **DONE**
   963→- ~~Reluctant Dounguard: replace Custom with `remove_counters("-1/-1", 1)`~~ **DONE**
   964→- ~~Heirloom Auntie: replace Custom with `remove_counters("-1/-1", 1)`~~ **DONE**
   965→
   966→### 8. Implement shock land ETB replacement effect
   967→Unblocks: Blood Crypt, Hallowed Fountain, Overgrown Tomb, Steam Vents, Temple Garden (5 lands).
   968→
   969→### 9. Implement Equipment attach/equip mechanics

### PARTIAL/STUB CARDS (150 CARDS)

All remaining 150 cards use at least one `Custom` effect. Key categories include:

1. **Vivid Mechanics** (color-based X effects) - ~15 cards (Explosive Prodigy, Luminollusk, Prismabasher, Shimmercreep, Shinestriker, etc.)

2. **Choice-based Modes** (choose creature type / choose one-two) - ~20 cards (Bloodline Bidding, Chronicle of Victory, Ashling's Command, Brigid's Command, etc.)

3. **Equipment/Attachment Effects** (attach with keyword grants) - ~10 cards (Barbed Bloodletter, Bark of Doran, various equipment)

4. **Ability Manipulation** (lose abilities, can't untap, can't block) - ~8 cards (Abigale Eloquent First-Year, Blossombind, etc.)

5. **Evoke Mechanics** - ~4 cards (Catharsis, Deceit, Emptiness, etc.)

6. **Library Mechanics** (look at top X with conditional reveal) - ~5 cards (Eclipsed Boggart through Eclipsed Merrow as a cycle)

7. **Blight Counter Mechanics** - ~8 cards (Boggart Mischief, Gutsplitter Gang, Soul Immolation, etc.)

8. **Land Mechanics** (pay life or enters tapped) - ~6 cards (Blood Crypt, various dual lands)

9. **Placeholder Effects** (generic "Static effect", "Activated effect", "ETB effect" stubs) - ~70+ cards needing proper implementation

### FILE LOCATION

**Source File:** `/mnt/dest-btrfs/home/jc/src/mage/mtg-rl/mtg-cards/src/sets/ecl.rs`  
**Lines:** 4,221 total  
**Functions:** 267 card factory functions

### NO-OP EFFECTS

No silent no-op effects were detected. All Custom effects represent unimplemented functionality that needs proper engine support.

Let me check whether Blight, RemoveCounters, and ExileFromGraveyard costs are actually handled in the engine.

Critical finding: `Cost::RemoveCounters`, `Cost::Blight`, and `Cost::Custom` are **all no-ops** in `pay_costs()` — they fall through to `_ => {}` and silently succeed without actually paying. This means cards using these costs are "overpowered" (ability always activatable). Let me now write the comprehensive update.

## User

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.

Analysis:
Let me chronologically analyze the conversation:

1. **First user message**: Read `docs/work-queue.md` and do the next unchecked batch. Detailed 10-step process for each batch including reading engine files, investigating uncertainties, adding tests, fixing cards, verifying, updating docs, etc.

2. **My actions for Batch 10**:
   - Read work-queue.md - found Batch 10 (Compound self-counter + target effects) was next
   - Read abilities.rs to understand Effect/StaticEffect variants
   - Grepped for Warren Torchmaster and Dream Seizer in ecl.rs
   - Found Dream Seizer was already fixed in Batch 3
   - Identified the core problem: Warren Torchmaster needs `add_counters("-1/-1", 1)` on SELF and `gain_keyword_eot("haste")` on TARGET - but current `AddCounters` uses targets when available
   - Read game.rs execute_effects to understand target handling
   - Read Java implementation of WarrenTorchmaster.java - uses BlightCost + ReflexiveTriggeredAbility
   - Solution: Add `Effect::AddCountersSelf` variant that always applies to source regardless of targets

3. **Engine changes made**:
   - Added `AddCountersSelf { counter_type: String, count: u32 }` to Effect enum in abilities.rs
   - Added `add_counters_self()` constructor
   - Added match arm in execute_effects in game.rs
   - Added test `add_counters_self_with_separate_target`
   - Fixed Warren Torchmaster in ecl.rs

4. **One error**: Edit tool failed on ecl.rs with "File has not been read yet" - fixed by reading the file first then editing.

5. **Verification**: `cargo check -p mtg-engine -p mtg-cards` and `cargo test --lib` both passed (255 tests).

6. **Doc updates**: Updated work-queue.md (Batch 10 done), ecl-remediation.md (Warren Torchmaster fixed), ROADMAP.md (Batch 10 note), MEMORY.md (added AddCountersSelf API info, updated batch count).

7. **Second user message**: "Let's commit the current work" (interrupted, then repeated)

8. **Commit actions**: Staged all files, committed as `cb70447e83` with message covering batches 4-10. 12 files changed, 1495 insertions, 180 deletions.

9. **Third user message**: "Let's look at @mtg-rl/docs/work-queue.md and @mtg-rl/docs/ecl-remediation.md and update ECL Remediation to match the current state, identify all the remaining work to complete ECL."

10. **ECL audit actions**:
    - Read both work-queue.md and ecl-remediation.md (full files)
    - Launched Explore agent to audit all 267 card functions in ecl.rs
    - Agent found 117 "complete" (no Custom) and 150 with Custom
    - Verified suspicious "complete" classifications - found many are pure placeholders
    - Checked specific cards flagged as "may be fully functional"
    - Critical discovery: `Cost::RemoveCounters`, `Cost::Blight`, `Cost::Custom` are ALL no-ops in pay_costs() - they silently succeed without paying
    - Counted 175 Custom effect occurrences in ecl.rs
    - Checked all 3 Cost::RemoveCounters and Cost::Blight usages

11. **ECL remediation doc updates**:
    - Updated overview counts (73 complete, 44 partial, ~150 stub)
    - Added "Additional Working Effects" section listing Batches 1-10 additions
    - Added "Non-functional Costs" section documenting cost no-ops
    - Promoted 13 cards from Partial → Complete: Adept Watershaper, Bile-Vial Boggart, Burdened Stoneback, Changeling Wayfinder, Dundoolin Weaver, Flame-Chain Mauler, Graveshifter, Lys Alana Informant, Shore Lurker, Unwelcome Sprite, Bristlebane Battler, Dose of Dawnglow, Midnight Tilling, Flamekin Gildweaver, Stratosoarer
    - Updated 3 cards with cost issue notes: Gnarlbark Elm, Moonlit Lamenter, Gristle Glutton
    - Fixed duplicate entries: Blossoming Defense, Kulrath Mystic
    - Added comprehensive "Remaining Work Summary" section organized by engine gap category
    - Listed 13 categories of remaining work with specific card counts

The summary request came right after completing the ECL remediation doc update. No commit was made for these doc changes.

Summary:
1. Primary Request and Intent:
   - **Batch 10 implementation**: User requested reading `docs/work-queue.md` and doing the next unchecked batch (Batch 10: Compound self-counter + target effects), following a detailed 10-step process: read engine files, investigate uncertainties, add engine changes if needed, add tests, fix cards, verify compilation/tests, update docs, check off the batch.
   - **Commit**: User requested committing all current work.
   - **ECL Remediation audit**: User requested reading work-queue.md and ecl-remediation.md, updating ECL Remediation doc to match current state, and identifying all remaining work to complete ECL.

2. Key Technical Concepts:
   - `Effect::AddCountersSelf` — new variant that always applies counters to the source permanent regardless of targets (unlike `AddCounters` which falls back to source only when targets are empty)
   - Compound effects where different effects in the same ability target different permanents (self vs chosen creature)
   - Java's `BlightCost` + `ReflexiveTriggeredAbility` pattern for "may blight, when you do" cards
   - `pay_costs()` in game.rs only implements TapSelf, Mana, PayLife, SacrificeSelf, Discard — all other costs (Blight, RemoveCounters, ExileFromGraveyard, Custom, etc.) silently succeed as no-ops
   - 175 Custom effect/cost occurrences remain in ECL set
   - ECL has 267 total cards: ~73 complete, ~44 partial, ~150 stubs

3. Files and Code Sections:
   - **`mtg-rl/mtg-engine/src/abilities.rs`**
     - Core Effect/StaticEffect/Cost enum definitions and constructors
     - Added `AddCountersSelf` variant between `AddCounters` and `AddCountersAll`:
     ```rust
     /// Put counters on the source permanent (self), regardless of targets.
     /// Used in compound effects where other effects target a different permanent.
     AddCountersSelf { counter_type: String, count: u32 },
     ```
     - Added constructor:
     ```rust
     pub fn add_counters_self(counter_type: &str, count: u32) -> Self {
         Effect::AddCountersSelf {
             counter_type: counter_type.to_string(),
             count,
         }
     }
     ```

   - **`mtg-rl/mtg-engine/src/game.rs`**
     - `execute_effects()` at line ~958: processes effects with target routing
     - Added match arm for `AddCountersSelf` after the `AddCounters` arm:
     ```rust
     Effect::AddCountersSelf { counter_type, count } => {
         if let Some(source_id) = source {
             let ct = crate::counters::CounterType::from_name(counter_type);
             if let Some(perm) = self.state.battlefield.get_mut(source_id) {
                 perm.add_counters(ct, *count);
             }
         }
     }
     ```
     - `pay_costs()` at line ~881: Only implements TapSelf, Mana, PayLife, SacrificeSelf, Discard. All other costs fall through to `_ => {}` (silent no-op).
     - Added test `add_counters_self_with_separate_target` after `add_counters_self_when_no_targets` test (around line 2672):
     ```rust
     #[test]
     fn add_counters_self_with_separate_target() {
         // Compound effect: AddCountersSelf puts -1/-1 on source while
         // GainKeywordUntilEndOfTurn gives haste to a different target.
         // ... creates two creatures, executes compound effect, verifies:
         // - Source has -1/-1 counter, no haste
         // - Target has haste, no -1/-1 counter
     }
     ```

   - **`mtg-rl/mtg-cards/src/sets/ecl.rs`**
     - Warren Torchmaster (line ~1682): Changed from `Effect::Custom(...)` to:
     ```rust
     Ability::triggered(id,
         "At the beginning of combat on your turn, you may put a -1/-1 counter on Warren Torchmaster. If you do, target creature gains haste until end of turn.",
         vec![EventType::BeginCombat],
         vec![Effect::add_counters_self("-1/-1", 1), Effect::gain_keyword_eot("haste")],
         TargetSpec::Creature).set_optional(),
     ```
     - 175 remaining Custom occurrences identified across Effect::Custom, StaticEffect::Custom, Cost::Custom

   - **`mtg-rl/docs/work-queue.md`**
     - Batch 10 marked as `[DONE 2026-02-14]`
     - Warren Torchmaster marked [x], Dream Seizer noted as already fixed in Batch 3
     - Next unchecked batch: Batch 11 (Modal spells)

   - **`mtg-rl/docs/ecl-remediation.md`**
     - Updated overview counts to 73 complete / 44 partial / ~150 stub
     - Added "Additional Working Effects" section (Batches 1-10 additions)
     - Added "Non-functional Costs" section documenting pay_costs() no-ops
     - Promoted 15 cards from Partial → Complete (Adept Watershaper, Bile-Vial Boggart, Burdened Stoneback, Changeling Wayfinder, Dundoolin Weaver, Flame-Chain Mauler, Graveshifter, Lys Alana Informant, Shore Lurker, Unwelcome Sprite, Bristlebane Battler, Dose of Dawnglow, Midnight Tilling, Flamekin Gildweaver, Stratosoarer)
     - Updated cost-broken partial cards (Gnarlbark Elm, Moonlit Lamenter, Gristle Glutton)
     - Added comprehensive "Remaining Work Summary" with 13 categories:
       1. Cost system gaps (RemoveCounters, Blight, ExileFromGraveyard)
       2. Vivid mechanic (8 cards)
       3. Modal spells (6+ cards)
       4. Equipment system (4 cards)
       5. Evoke mechanic (3 cards)
       6. Eclipsed cycle - look at top 4 (5 cards)
       7. Impulse draw (3 cards)
       8. Behold mechanic (4 cards)
       9. Shock lands (5 lands)
       10. Conditional/dynamic effects (scattered)
       11. Aura system (5+ cards)
       12. Planeswalker (1 card)
       13. Pure stubs (70+ cards)

   - **`mtg-rl/ROADMAP.md`**
     - Added Batch 10 note about AddCountersSelf
     - Added Warren Torchmaster to the Phase 1 completed list

   - **`Mage.Sets/src/mage/cards/w/WarrenTorchmaster.java`**
     - Read for reference: uses `BeginningOfCombatTriggeredAbility` → `DoWhenCostPaid(reflexiveAbility, BlightCost(1), "Blight 1?")` → `ReflexiveTriggeredAbility(GainAbilityTargetEffect(HasteAbility), target: TargetCreaturePermanent)`

   - **`~/.claude/projects/.../memory/MEMORY.md`**
     - Added `Effect::AddCountersSelf` to API notes
     - Updated batch count: "Batches 1-10 done; Batch 11 (modal spells) is next"

4. Errors and fixes:
   - **Edit tool "File has not been read yet" error on ecl.rs**: When trying to edit Warren Torchmaster in ecl.rs, the Edit tool rejected because the file hadn't been Read yet (only Grep results existed). Fixed by reading the specific line range first with `Read` tool, then applying the edit.

5. Problem Solving:
   - **Compound effect target routing**: The core problem was that `AddCounters` uses the ability's targets when available, so a compound `[AddCounters, GainKeywordUntilEndOfTurn]` with `TargetSpec::Creature` would put counters on the target creature instead of self. Solved by creating a new `AddCountersSelf` variant that ignores targets entirely.
   - **Cost system audit**: Discovered during ECL remediation that most cost types are unimplemented no-ops, affecting card correctness for Gnarlbark Elm, Moonlit Lamenter, Gristle Glutton, Goldmeadow Nomad, Stoic Grove-Guide.
   - **Card classification accuracy**: The Explore agent classified ~117 cards as "complete" but many were pure placeholders with no abilities. Verified by reading actual card functions and properly distinguishing between truly complete, simplified-but-functional, and placeholder cards.

6. All user messages:
   - "Read `docs/work-queue.md` and do the next unchecked batch. For each batch: [10-step detailed process including reading engine files, investigating uncertainties, adding tests, fixing cards, verifying, updating docs]"
   - "Let's commit the current work" (interrupted)
   - "Let's commit the current work"
   - "Let's look at @mtg-rl/docs/work-queue.md and @mtg-rl/docs/ecl-remediation.md and update ECL Remediation to match the current state, identify all the remaining work to complete ECL."

7. Pending Tasks:
   - The ECL remediation doc updates have NOT been committed yet (changes made after the cb70447e83 commit)
   - No explicit pending task was requested beyond the ECL audit (which is now complete)

8. Current Work:
   Just completed the comprehensive ECL remediation doc update. The last actions were:
   - Adding the "Remaining Work Summary" section at the end of `docs/ecl-remediation.md` with 13 categories of remaining work organized by engine gap
   - Promoting 15 cards from Partial → Complete
   - Adding cost system no-op documentation
   - These changes are uncommitted (made after the `cb70447e83` commit)

9. Optional Next Step:
   The ECL remediation audit is complete. The uncommitted changes to `docs/ecl-remediation.md` could be committed if the user requests it. No further explicit task was requested.

If you need specific details from before compaction (like exact code snippets, error messages, or content you generated), read the full transcript at: /mnt/dest-btrfs/home/jc/.claude/projects/-mnt-dest-btrfs-home-jc-src-mage/beabe26f-1ea7-4155-ae62-5eeca1d2a60c.jsonl
Please continue the conversation from where we left off without asking the user any further questions. Continue with the last task that you were asked to work on.

- Added comprehensive "Remaining Work Summary" with 13 categories of remaining work:
  1. Cost system gaps (RemoveCounters, Blight, ExileFromGraveyard)
  2. Vivid mechanic (8 cards)
  3. Modal spells (6+ cards)
  4. Equipment system (4 cards)

These doc changes are staged but not committed. The last commit was `cb70447e83` which covered Batches 4-10. Let me know what you'd like to do next — commit these doc updates, continue with the next batch (Batch 11: Modal spells), or something else.

## User

Let's think about the work to complete the set (ECL) as a graph, with the root being 'ECL Complete', the final leaves being the cards, and interior nodes being the engine capabilities needed to complete, and edges from the cards to the interior nodes, and from the interior nodes to the root. If a card needs no engine capability, then it can connect directly to the root. Let's start by creating this graph as a mermaid diagram.

    12→## How to Fix Cards
    13→
    14→### Engine Context
    15→The Rust MTG engine is structured as a Cargo workspace with these key crates:
    16→
    17→- **mtg-engine** (`mtg-engine/src/`) — Core game logic
    18→  - `game.rs` — Game loop and `execute_effects()` dispatcher
    19→  - `abilities.rs` — `Effect`, `StaticEffect`, `Cost`, `Ability`, `TargetSpec` enums and constructors
    20→  - `effects.rs` — `StaticEffect` variant definitions
    21→  - `constants.rs` — `CardType`, `SubType`, `KeywordAbilities`, `Rarity`, etc.
    22→  - `events.rs` — `EventType` enum for triggers
    23→- **mtg-cards** (`mtg-cards/src/`) — Card definitions
    24→  - `sets/ecl.rs` — All ECL card factory functions
    25→  - `registry.rs` — `CardRegistry` for name-to-factory mapping
    26→
    27→### Working Effects (handled in `execute_effects()`)
    28→These `Effect` variants have actual implementations in the game engine:
    29→- `Effect::DealDamage { amount }` / `deal_damage(n)`
    30→- `Effect::Destroy` / `destroy()`
    31→- `Effect::Exile` / `exile()`
    32→- `Effect::Bounce` / `bounce()` (return to hand)
    33→- `Effect::DrawCards { count }` / `draw_cards(n)`
    34→- `Effect::GainLife { amount }` / `gain_life(n)`
    35→- `Effect::LoseLife { amount }` / `lose_life(n)`
    36→- `Effect::DealDamageOpponents { amount }` / `damage_opponents(n)`
    37→- `Effect::AddCounters { counter_type, count }` / `add_counters(type, n)`
    38→- `Effect::BoostUntilEndOfTurn { power, toughness }` / `boost_until_eot(p, t)`
    39→- `Effect::TapTarget` / (via tap effects)
    40→- `Effect::UntapTarget` / (via untap effects)
    41→- `Effect::CounterSpell` / `counter_spell()`
    42→- `Effect::AddMana { mana }` / (via mana abilities)
    43→- `Effect::DiscardCards { count }` / `discard_cards(n)`
    44→- `Effect::Mill { count }` / `mill(n)`
    45→- `Effect::CreateToken { token_name, count }` / `create_token(name, n)` — now parses P/T and keywords from token_name
    46→- `Effect::Scry { count }` / `scry(n)`
    47→- `Effect::SearchLibrary { filter }` / `search_library(filter)`
    48→- `Effect::ReturnFromGraveyard` / `return_from_graveyard()`
    49→- `Effect::Reanimate` / `reanimate()`
    50→- `Effect::GainKeywordUntilEndOfTurn { keyword }` / `gain_keyword_eot(kw)`
    51→- `Effect::GainKeyword { keyword }` / `gain_keyword(kw)`

    59→- `Effect::RemoveCounters { counter_type, count }` / `remove_counters(type, n)`
    60→- `Effect::CreateTokenTappedAttacking { token_name, count }` / `create_token_tapped_attacking(name, n)`
    61→- `Effect::BoostPermanent { power, toughness }` / `boost_permanent(p, t)`
    62→- `Effect::SetPowerToughness { power, toughness }` / `set_power_toughness(p, t)`
    63→
    64→### Additional Working Effects (added in Batches 1-10)
    65→- `Effect::LoseLifeOpponents { amount }` / `lose_life_opponents(n)` — Batch 1
    66→- `Effect::DiscardOpponents { count }` / `discard_opponents(n)` — Batch 3
    67→- `Effect::BoostAllUntilEndOfTurn { filter, power, toughness }` / `boost_all_eot()` — Batch 7
    68→- `Effect::GrantKeywordAllUntilEndOfTurn { filter, keyword }` / `grant_keyword_all_eot()` — Batch 7
    69→- `Effect::Fight` / `Effect::Bite` — Batch 8
    70→- `Effect::AddCountersAll { counter_type, count, filter }` / `add_counters_all()` — Batch 9
    71→- `Effect::AddCountersSelf { counter_type, count }` / `add_counters_self()` — Batch 10
    72→- `StaticEffect::Ward { cost }` / `ward()` — Batch 5
    73→- `StaticEffect::EntersTappedUnless { condition }` — Batch 6
    74→
    75→### Non-functional Effects (NO-OP at runtime)
    76→These fall through to `_ => {}` in `execute_effects()`:
    77→- `Effect::SetLife` — Set life total
    78→- `Effect::MustBlock` — Force blocking
    79→- `Effect::PreventCombatDamage` — Prevent damage
    80→- `Effect::GainControl` / `GainControlUntilEndOfTurn` — Steal
    81→- `Effect::GainProtection` — Protection
    82→- `Effect::Custom(...)` — always a no-op
    83→- `StaticEffect::Custom(...)` — non-functional in continuous effects system
    84→
    85→### Non-functional Costs (silently succeed without paying)
    86→These fall through to `_ => {}` in `pay_costs()` — abilities using them can be activated for free:
    87→- `Cost::Blight(n)` — should put -1/-1 counters but doesn't
    88→- `Cost::RemoveCounters(type, n)` — should remove counters but doesn't
    89→- `Cost::ExileFromGraveyard(n)` — should exile but doesn't
    90→- `Cost::ExileFromHand(n)` — should exile but doesn't
    91→- `Cost::SacrificeOther(filter)` — should sacrifice but doesn't
    92→- `Cost::UntapSelf` — should untap but doesn't
    93→- `Cost::RevealFromHand(type)` — should reveal but doesn't
    94→- `Cost::Custom(...)` — always a no-op
    95→
    96→### Adding a New Effect Type
    97→1. Add the variant to the `Effect` enum in `mtg-engine/src/abilities.rs`
    98→2. Add a convenience constructor (e.g., `pub fn my_effect() -> Self { Effect::MyEffect }`)
    99→3. Handle the variant in the `execute_effects()` match in `mtg-engine/src/game.rs`
   100→4. Update card code in `mtg-cards/src/sets/ecl.rs` to use the new typed variant instead of `Effect::Custom`

   167→## Partial Cards
   168→These cards have some typed effects that work but also use `Effect::Custom`, `StaticEffect::Custom`, or `Cost::Custom` for one or more abilities. The Custom parts are no-ops.
   169→
   170→- [x] **Adept Watershaper** — COMPLETE. Static `grant_keyword_controlled("other tapped creatures you control", "indestructible")`. No Custom effects. (Note: "tapped" filter condition not mechanically enforced — grants to all creatures you control.)
   171→  - **Java source**: `Mage.Sets/src/mage/cards/a/AdeptWatershaper.java`
   172→
   173→- [x] **Bile-Vial Boggart** — COMPLETE. Dies trigger `add_counters("-1/-1", 1)` with `TargetSpec::Creature`. All typed, no Custom.
   174→  - **Java source**: `Mage.Sets/src/mage/cards/b/BileVialBoggart.java`
   175→
   176→- [x] **Blighted Blackthorn** — ETB/attacks: `add_counters("-1/-1", 2)` + `draw_cards(1)` + `lose_life(1)` — **FIXED** (was `Effect::Custom("Put two -1/-1 counters on Blighted Blackthorn")`, now uses typed `add_counters` with source fallback)

  1051→### Quick wins (fix without engine changes)
  1052→These cards could be fixed by replacing Custom effects with existing typed variants:
  1053→- **Iron-Shield Elf**: Replace `Effect::Custom("Tap Iron-Shield Elf.")` with self-tap effect (could use `Effect::TapTarget` on self, but need to verify targeting)
  1054→- **Glamermite**: Replace `Effect::Custom("Tap or untap target creature.")` — could use `Effect::TapTarget` or `Effect::UntapTarget` (but needs player choice)
  1055→- **Scarblades Malice**: Keyword grants work; only missing delayed death trigger for 2/2 Elf token
  1056→- **Crib Swap**: `exile()` works; needs token creation for target's controller
  1057→- **Rooftop Percher**: `gain_life(3)` works; needs targeted graveyard exile
  1058→- **Boggart Mischief**: Dies trigger works; ETB blight+token still Custom

Perfect! Now I have the complete analysis. Let me provide a final summary output:

## ECL (Eclogue) Set - Complete Card Categorization by Engine Capability

I've analyzed all **267 cards** in `/mnt/dest-btrfs/home/jc/src/mage/mtg-rl/mtg-cards/src/sets/ecl.rs`. Here are the results:

### Summary by Category:

| Category | # Cards | Description |
|----------|---------|-------------|
| **1** | 176 | **Already complete** - No Custom effects/costs, all abilities properly typed |
| **2** | 3 | **Needs cost system** - Uses `Cost::Blight`, `Cost::RemoveCounters`, `Cost::ExileFromGraveyard` |
| **3** | 6 | **Needs modal spells** - Has choose one/two/three mechanics |
| **4** | 4 | **Needs equipment system** - Equipment cards |
| **5** | 3 | **Needs evoke** - Has evoke mechanic |
| **6** | 9 | **Needs vivid** - References vivid (color-counting) mechanic |
| **7** | 3 | **Needs behold** - References behold mechanic |
| **8** | 18 | **Needs impulse draw** - Exile-and-play-until-end-of-turn effects |
| **9** | 9 | **Needs aura system** - Aura cards that attach to creatures |
| **10** | 2 | **Needs planeswalker** - Planeswalker cards |
| **13** | 2 | **Needs spell copy** - Copies spells on the stack |
| **16** | 1 | **Needs gain control** - Steals permanents from opponents |
| **18** | 28 | **Pure stub** - Very minimal implementations, need full implementation from scratch |
| **19** | 3 | **Needs multiple systems** - Combines 2+ of the above |
| | **267** | **TOTAL** |

### Key Findings:

- **176 cards (66%)** are already complete with proper typed effects
- **28 cards (10%)** are pure stubs needing full implementation
- **Biggest engine gaps:**
  - Impulse draw (18 cards) - Exile and play until end of turn
  - Vivid mechanic (9 cards) - Color-counting effects
  - Aura system (9 cards) - Creature-enchantment attachment
  - Modal spells (6 cards) - Choose one/two mechanics
  - Cost system (3 cards) - Blight/RemoveCounters costs

### Complete Card List with Categories:

The full detailed list shows each of the 267 cards categorized by its primary engine need. Cards like `abigale_eloquent_first_year`, `adept_watershaper`, and `appeal_to_eirdu` are already complete, while cards like `burning_curiosity`, `aurora_awakener`, and `aguist's_defenses` need specific engine subsystems.

181 remaining)**\n\n## Critical Path\n\nThe most impactful engine capabilities to implement (by cards unblocked):\n\n1. **Research & triage the 91 stub cards** — Many may turn out to be vanilla creatures (already done), while others will feed into existing capability categories\n2. **Conditional/Dynamic Effects** (13 cards total) — Unlocks the most categorized cards\n3. **Vivid Mechanic** (9 cards) — Single engine addition unlocks an entire cycle\n4. **Aura System** (9 cards) — Broadly useful beyond ECL\n5. **Cost System** (8 cards) — Small `pay_costs()` additions, high ROI\n6. **Player Choice** (8 cards) — Needed for many partial cards\n7. **Modal Spells** (6 cards) — Reusable across all sets\n",

## Assistant

All 267 cards verified. The graph is at `docs/ecl-dependency-graph.md`. Here's the structure:

**ECL Complete** (root)
- **86 complete cards** connect directly to root
- **21 engine capability nodes** in the middle layer:

| Capability | Cards | Notes |
|---|---|---|
| Research & Implementation | 93 | Need Java source analysis first |
| Conditional/Dynamic | 12 | Most diverse category |
| Cost System | 9 | `pay_costs()` match arms |
| Vivid Mechanic | 9 | Color-counting for X |
| Aura System | 9 | Creature enchantment |
| Player Choice | 8 | Runtime decisions |
| Misc Effects | 6 | Individual small fixes |
| Modal Spells | 5 | Choose one/two |
| Shock Lands | 5 | ETB replacement |
| Eclipsed Cycle | 5 | Look at top 4 |
| Equipment | 4 | Attach/detach/equip |
| Behold | 4 | Reveal+exile from hand |
| Creature Type Choice | 4 | Choose-type |
| Dynamic Mana | 3 | Color-dependent production |
| Evoke | 3 | Alt cost + sacrifice |
| Impulse Draw | 3 | Exile-and-play |
| Spell Copy, PW, Control, Delayed, Cast-from-Exile | 1 each | |

6 multi-dependency cards have edges to 2 capabilities each (e.g., Champion of the Weird needs both Behold and Cost System).
