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
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
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` 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 .")` 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)
187→
188→**Engine**: Need `Effect::AddCountersAll { counter_type, count, filter }` — similar pattern to `DestroyAll`/`DealDamageAll`. Puts N counters on all permanents matching filter.
189→
190→**Cards:**
191→- [ ] ECL: Darkness Descends — `Custom("Put two -1/-1 counters on each creature.")` → `Effect::AddCountersAll { counter_type: "-1/-1", count: 2, filter: "creatures" }`
192→
193→---
194→
195→## Batch 10: Compound self-counter + target effects
196→
197→**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.
198→
199→**Cards:**
200→- [ ] 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.
201→- [ ] ECL: Dream Seizer — ETB: self -1/-1 counter + each opponent discards (also depends on Batch 3 OpponentDiscards)
202→
203→---
204→
205→## Batch 11: Modal spells (Choose one/two)
206→
207→**Engine**: Modal framework — player chooses mode, effects resolve based on mode selection.
208→
209→**Cards (~15+):**
210→- [ ] FDN: Abrade, Boros Charm, Slagstorm, Valorous Stance, Charming Prince
211→- [ ] TDM: multiple
212→- [ ] ECL: multiple
213→
214→---
215→
216→## Batch 12+: Larger systems
217→
218→These require more significant engine work:
219→- Equipment attach/detach (Batch 12)
220→- Planeswalker loyalty (Batch 13)
221→- Token copy (Batch 14)
222→- X-cost spells (Batch 15)
223→- Aura attachment (Batch 16)
224→- Impulse draw / exile-and-play (Batch 17)
225→- Sagas / lore counters (Batch 18)
226→- Set mechanics: Earthbend (TLA), Blight (ECL), Vivid (ECL), Behold (ECL) (Batch 19+)
227→- Cost system: `Cost::Custom` for counter removal (ECL line ~464), `Cost::RemoveCounters`, `Cost::ExileFromGraveyard`
228→
229→---
230→
231→## How to pick the next batch
232→
233→1. Always do the lowest-numbered unchecked batch first
234→2. If a batch has a NOTE about engine uncertainty, investigate before committing
235→3. After finishing a batch, update this file AND the per-set remediation docs
236→4. Run `cargo test --lib` before and after every batch

Now I have everything I need. Let me implement:
1. Add `AddCountersAll` variant to Effect enum in abilities.rs
2. Add `add_counters_all()` constructor
3. Add match arm in game.rs `execute_effects`
4. Add test in game.rs
5. Fix cards in ecl.rs and tdm.rs

I see — it uses `Game::new_two_player` with `GameConfig`. Let me also check what `make_deck` does:

11:[Omitted long matching line]
13:**Batch 2 engine change (2026-02-13):** Modified `execute_effects` to accept an optional `source: Option` 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`.
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.
