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.

## Assistant

I'll start by reading the work queue to find the next unchecked batch.

     7→1. **Read this file** to find the next unchecked batch
     8→2. **Read the engine files** (`abilities.rs`, `game.rs`) to understand current state
     9→3. **Implement** the engine change (new Effect/StaticEffect variant + match arm), if needed
    10→4. **Add a test** for any new engine effect in `game.rs` `mod tests`
    11→5. **Fix the cards** listed in the batch (grep to find exact lines)
    12→6. **Verify**: `cargo check -p mtg-cards && cargo test --lib`
    13→7. **Update docs**: Mark cards fixed in `docs/{set}-remediation.md`, update ROADMAP.md

    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 — stub cards with full token text
    84→
    85→**Engine**: `CreateToken` already works and parses P/T + keywords from name. These cards use `Custom(...)` with text that describes standard token creation.
    86→
    87→**Cards** (grep for `Custom("Create` and `Custom("When this creature enters, create`):
    88→- [ ] FDN line ~6199: (card?) — `Custom("create two 3/3 white Knight creature tokens")`
    89→- [ ] FDN line ~6005: (card?) — `Custom("Create two 1/1 blue Faerie creature tokens with flying...")`
    90→- [ ] FDN line ~5623: (card?) — `Custom("create a Food token")`
    91→- [ ] FDN line ~5899: (card?) — `Custom("create a 1/1 green Elf Warrior creature token")` (conditional)
    92→- [ ] ECL line ~3704: (card?) — `Custom("create two 1/1 green and white Kithkin creature tokens")`
    93→- [ ] ECL line ~3709: (card?) — `Custom("{4}{W}: Create a 1/1 green and white Kithkin creature token")`
    94→- **NOTE**: Some of these are inside stubs where the entire ability structure is placeholder. Check if the `Ability::` wrapper is correct (trigger type, costs) before just swapping the effect. Some may need the whole ability rewritten.
    95→
    96→---
    97→
    98→## Batch 5: Ward keyword
    99→
   100→**Engine**: Ward is a triggered ability ("When this becomes the target of a spell or ability an opponent controls, counter it unless that player pays {cost}"). Options:
   101→- A) Add `KeywordAbilities::WARD` flag + hardcode Ward {2} behavior in the targeting/stack system
   102→- B) Model as a triggered ability with a special `Effect::Ward { cost }`
   103→- C) Simpler: Add `StaticEffect::Ward { cost: String }` that the engine recognizes during targeting
   104→
   105→**Cards (6):**
   106→- [ ] TDM line ~347, ~1990, ~3729: three creatures with `StaticEffect::Custom("Ward {2}")`
   107→- [ ] TDM line ~4078: `StaticEffect::Custom("Ward -- Discard a card.")`
   108→- [ ] ECL line ~2189: `StaticEffect::Custom("Ward {2}")`
   109→- [ ] FDN line ~5603: `StaticEffect::Custom("Ward {2}")`
   110→
   111→---
   112→
   113→## Batch 6: Enters-tapped-unless (conditional ETB tapped)
   114→
   115→**Engine**: May need `StaticEffect::EntersTappedUnless { condition }` or similar.
   116→
   117→**Cards:**
   118→- [ ] TDM line ~2110: `StaticEffect::Custom("Enters tapped unless you control Plains or Island.")`
   119→- [ ] TDM line ~2153: `StaticEffect::Custom("Enters tapped unless you control Swamp or Mountain.")`
   120→
   121→---
   122→
   123→## Batch 7: Mass keyword grant until EOT
   124→
   125→**Engine**: Need `Effect::GrantKeywordAllUntilEndOfTurn { filter, keyword }` or similar mass-buff effect.
   126→
   127→**Cards:**
   128→- [ ] FDN: Crash Through — `Custom("Creatures you control gain trample until end of turn.")` + DrawCards(1)
   129→- [ ] FDN: Overrun — `Custom("Creatures you control get +3/+3 and gain trample until end of turn.")`
   130→- [ ] FDN: Make a Stand — `Custom("Creatures you control get +1/+0 and gain indestructible until end of turn.")`
   131→- [ ] FDN: Heroic Reinforcements — `Custom(...)` mass +1/+1 and haste
   132→- [ ] FDN: Balmor, Battlemage Captain — spell trigger mass +1/+0 and trample
   133→
   134→---
   135→
   136→## Batch 8: Fight/Bite mechanic
   137→
   138→**Engine**: New `Effect::Fight` (mutual damage) and/or `Effect::Bite` (one-way damage based on power).
   139→
   140→**Cards (~10):**
   141→- [ ] FDN: Bite Down
   142→- [ ] ECL: multiple fight cards
   143→- [ ] TLA: Earth Rumble, others
   144→
   145→---
   146→
   147→## Batch 9: AddCountersAll (mass counter placement)
   148→
   149→**Engine**: Need `Effect::AddCountersAll { counter_type, count, filter }` — similar pattern to `DestroyAll`/`DealDamageAll`. Puts N counters on all permanents matching filter.
   150→
   151→**Cards:**
   152→- [ ] ECL: Darkness Descends — `Custom("Put two -1/-1 counters on each creature.")` → `Effect::AddCountersAll { counter_type: "-1/-1", count: 2, filter: "creatures" }`
   153→
   154→---
   155→
   156→## Batch 10: Compound self-counter + target effects
   157→
   158→**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.
   159→
   160→**Cards:**
   161→- [ ] 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.
   162→- [ ] ECL: Dream Seizer — ETB: self -1/-1 counter + each opponent discards (also depends on Batch 3 OpponentDiscards)
   163→
   164→---
   165→
   166→## Batch 11: Modal spells (Choose one/two)
   167→
   168→**Engine**: Modal framework — player chooses mode, effects resolve based on mode selection.
   169→
   170→**Cards (~15+):**
   171→- [ ] FDN: Abrade, Boros Charm, Slagstorm, Valorous Stance, Charming Prince
   172→- [ ] TDM: multiple
   173→- [ ] ECL: multiple
   174→
   175→---
   176→
   177→## Batch 12+: Larger systems
   178→
   179→These require more significant engine work:
   180→- Equipment attach/detach (Batch 12)
   181→- Planeswalker loyalty (Batch 13)
   182→- Token copy (Batch 14)
   183→- X-cost spells (Batch 15)
   184→- Aura attachment (Batch 16)
   185→- Impulse draw / exile-and-play (Batch 17)
   186→- Sagas / lore counters (Batch 18)
   187→- Set mechanics: Earthbend (TLA), Blight (ECL), Vivid (ECL), Behold (ECL) (Batch 19+)
   188→- Cost system: `Cost::Custom` for counter removal (ECL line ~464), `Cost::RemoveCounters`, `Cost::ExileFromGraveyard`
   189→
   190→---
   191→
   192→## How to pick the next batch
   193→
   194→1. Always do the lowest-numbered unchecked batch first
   195→2. If a batch has a NOTE about engine uncertainty, investigate before committing
   196→3. After finishing a batch, update this file AND the per-set remediation docs
   197→4. Run `cargo test --lib` before and after every batch
   198→

Now I have a complete picture. Let me execute the batch:

**Fixable cards (simple `Custom(...)` → `create_token(...)`):**
- FDN: Guarded Heir, Prideful Parent, Resolute Reinforcements, Release the Dogs, Dwynen's Elite, Dragonmaster Outcast, Searslicer Goblin (7 cards)
- ECL: Clachan Festival (2 effects + 1 cost fix)

**Skipping:**
- Food tokens (Cat Collector, Mender's Bounty) — artifact tokens, not creature. Needs engine change.
- Faebloom Trick — compound effect (tokens + reflexive trigger tap)

Let me make all the edits and add a test.

   544→
   545→*(This section continues for approximately 230 more cards. The pattern is the same: cards from the Tier 3 batch 2 onward (line ~3170 in fdn.rs) through the "New Creatures", "New Instants and Sorceries", "New Lands", "New Artifacts", "New Enchantments", and "Other" sections all use generic placeholder `Effect::Custom("ETB effect.")`, `Effect::Custom("Spell effect.")`, `StaticEffect::Custom("Static effect.")` etc. These are all stubs.)*
   546→
   547→### Notable high-value stubs that should be prioritized:
   548→
   549→- [ ] **Dimir Guildgate** / **Golgari Guildgate** / **Gruul Guildgate** / **Izzet Guildgate** / **Orzhov Guildgate** / **Rakdos Guildgate** / **Selesnya Guildgate** / **Simic Guildgate** -- All missing enters-tapped + dual mana abilities. Easy fix: copy Azorius/Boros Guildgate pattern.
   550→
   551→- [ ] **All 10 Temple lands** (Temple of Abandon, Deceit, Enlightenment, Epiphany, Malady, Malice, Mystery, Plenty, Silence, Triumph) -- All stubs. Should have enters-tapped + scry 1 + dual mana.

     1→# Roadmap
     2→
     3→This document describes implementation gaps in the mtg-rl engine and cards, organized by priority. Each engine feature lists how many cards it would unblock when implemented.
     4→
     5→## Engine Gaps
     6→
     7→### Effect Variants (game.rs `execute_effects()`)
     8→
     9→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.
    10→
    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→| Effect Variant | Description | Cards Blocked |
    16→|---------------|-------------|---------------|
    17→| `GainControl` | Gain control of target permanent | ~5 |
    18→| `GainControlUntilEndOfTurn` | Threaten/Act of Treason effects | ~5 |
    19→| `GainProtection` | Target gains protection from quality | ~5 |
    20→| `PreventCombatDamage` | Fog / damage prevention | ~5 |
    21→| `MustBlock` | Target creature must block | ~3 |
    22→| `SetLife` | Set a player's life total | ~2 |
    23→| `Custom(String)` | Catch-all for untyped effects | ~400+ |
    24→
    25→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.
    26→
    27→### Missing Engine Systems
    28→
    29→These are features that require new engine architecture, not just new match arms:
    30→
    31→#### Equipment System
    32→- No attach/detach mechanics
    33→- Equipment stat bonuses not applied
    34→- Equip cost not evaluated

    59→
    60→#### Aura/Enchant System
    61→- Auras exist as permanents but don't attach to creatures
    62→- Static P/T boosts from Auras not applied

    68→- **Blocked cards:** Equilibrium Adept, Kulrath Zealot, Sizzling Changeling, Burning Curiosity, Etali (~10+ cards)
    69→
    70→#### Spell Copy
    71→- No mechanism to copy spells on the stack
    72→- **Blocked cards:** Electroduplicate, Rite of Replication, Self-Reflection, Flamehold Grappler, Sage of the Skies (~8+ cards)
    73→
    74→#### Replacement Effects
    75→- `ReplacementEffect` struct exists in `effects.rs` but is not integrated into the event pipeline
    76→- Events are not interceptable before they resolve
    77→- **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
    78→
    79→#### Additional Combat Phases
    80→- No support for extra combat steps
    81→- **Blocked cards:** Aurelia the Warleader, All-Out Assault (~3 cards)
    82→
    83→#### "Behold" Mechanic (ECL-specific)
    84→- Reveal-and-exile-from-hand mechanic not implemented

    91→
    92→#### "Vivid" Mechanic (ECL-specific)
    93→- "X = number of colors among permanents you control" calculation not implemented
    94→- **Blocked cards:** Explosive Prodigy, Glister Bairn, Luminollusk, Prismabasher, Shimmercreep, Shinestriker, Squawkroaster (~10+ cards)
    95→
    96→#### Delayed Triggers
    97→- "When this creature dies this turn, draw a card" style effects
    98→- No framework for registering one-shot triggered abilities
    99→- **Blocked cards:** Undying Malice, Fake Your Own Death, Desperate Measures, Scarblades Malice (~5+ cards)
   100→
   101→#### Conditional Cost Modifications
   102→- `CostReduction` static effect exists but may not apply correctly
   103→- No support for "second spell costs {1} less" or Affinity
   104→- **Blocked cards:** Highspire Bell-Ringer, Allies at Last, Ghalta Primal Hunger (~5+ cards)
   105→
   106→---
   107→
   108→## Phased Implementation Plan
   109→
   110→### Phase 1: High-Impact Engine Effects
   111→
   112→These unblock the most cards per effort invested.
   113→
   114→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.
   115→
   116→2. **Fix easy card-level bugs** -- Many cards use `Effect::Custom(...)` when a typed variant already exists. Examples:
   117→   - ~~Phyrexian Arena: `Custom("You lose 1 life.")` -> `LoseLife { amount: 1 }`~~ **DONE**
   118→   - ~~Pulse Tracker/Marauding Blight-Priest/Vampire Spawn/Vampire Neonate: `Custom("Each opponent loses N life")` -> `LoseLifeOpponents { amount: N }`~~ **DONE**
   119→   - ~~Skirmish Rhino (TDM), Champion of the Weird (ECL), Boggart Mischief (ECL): opponent life loss Custom -> `LoseLifeOpponents`~~ **DONE**
   120→   - ~~Diregraf Ghoul: `StaticEffect::Custom("Enters tapped.")` -> `StaticEffect::EntersTapped`~~ **DONE**
   121→   - Incomplete dual lands: copy the Azorius Guildgate / Bloodfell Caves pattern
   122→   - ~~Sourbread Auntie/Sting-Slinger/Blighted Blackthorn: self-counter Custom -> `AddCounters` targeting self~~ **DONE**
   123→   - ~~Day of Judgment: `Custom("Destroy all creatures.")` -> `DestroyAll`~~ **DONE**
   124→   - ~~Frenzied Goblin/Brambleback Brute: `Custom("can't block")` -> `CantBlock`~~ **DONE**
   125→   - ~~Icewind Elemental/Refute: loot/counter Custom -> typed effects~~ **DONE**
   126→   - ~~ECL RemoveCounters cards (Encumbered Reejerey, Reluctant Dounguard, Heirloom Auntie, Bristlebane Battler): Custom -> `RemoveCounters` with source fallback~~ **DONE**
   127→   - ~~Mistmeadow Council: Custom -> `draw_cards(1)`~~ **DONE**
   128→   - ~~Burglar Rat/Dream Seizer/Arbiter of Woe/Bloodtithe Collector: opponent discard Custom -> `DiscardOpponents { count }`~~ **DONE**
   129→
   130→3. **Fight mechanic** -- New `Effect::Fight` variant. Two creatures deal damage equal to their power to each other. Unblocks ~10 cards.
   131→
   132→### Phase 2: Key Missing Mechanics
   133→
   134→4. **Equipment system** -- Attach/detach, equip cost, stat/keyword application. Unblocks ~15 cards.
   135→
   136→5. **Modal spells** -- Mode selection in `PlayerDecisionMaker` trait, mode-conditional effect resolution. Unblocks ~20 cards.
   137→
   138→6. **Impulse draw** -- "Exile top N, may play until end of [next] turn." Track exiled-playable cards in game state. Unblocks ~10 cards.
   139→
   140→7. **Earthbend** (TLA-specific) -- "Look at top N, put a land to hand, rest on bottom." Unblocks ~20 TLA cards.
   141→
   142→### Phase 3: Advanced Systems
   143→
   144→8. **Replacement effects** -- Event interception pipeline. Required for damage prevention, death replacement, Doubling Season, "exile instead of dying."
   145→
   146→9. **X-cost spells** -- Variable cost determination + passing X to effects.
   147→
   148→10. **Aura attachment** -- Auras attach to targets, apply continuous effects while attached.
   149→
   150→11. **Spell copy** -- Clone spells on the stack with new targets.
   151→
   152→12. **Planeswalker system** -- Loyalty as a resource, planeswalker abilities, damage redirection.
   153→
   154→13. **Additional combat phases** -- Extra attack steps.
   155→
   156→### Phase 4: Set-Specific Mechanics
   157→
   158→14. **Behold** (ECL) -- Reveal-from-hand alternative cost/condition.
   159→15. **Vivid** (ECL) -- Color-count calculation for dynamic X values.
   160→16. **Learn** (TLA) -- May discard to draw keyword action.
   161→17. **Renew** (TDM) -- Counter-based death replacement.
   162→18. **Mobilize** (TDM) -- Create N 1/1 Soldier tokens. (Partially works via `CreateToken` already.)
   163→
   164→---
   165→
   166→## Per-Set Status
   167→
   168→Detailed per-card breakdowns with fix instructions are in `docs/`:

    83→## Batch 4: Simple token creation — stub cards with full token text
    84→
    85→**Engine**: `CreateToken` already works and parses P/T + keywords from name. These cards use `Custom(...)` with text that describes standard token creation.
    86→
    87→**Cards** (grep for `Custom("Create` and `Custom("When this creature enters, create`):
    88→- [ ] FDN line ~6199: (card?) — `Custom("create two 3/3 white Knight creature tokens")`

    97→
    98→## Batch 5: Ward keyword
    99→
   100→**Engine**: Ward is a triggered ability ("When this becomes the target of a spell or ability an opponent controls, counter it unless that player pays {cost}"). Options:
   101→- A) Add `KeywordAbilities::WARD` flag + hardcode Ward {2} behavior in the targeting/stack system
   102→- B) Model as a triggered ability with a special `Effect::Ward { cost }`
   103→- C) Simpler: Add `StaticEffect::Ward { cost: String }` that the engine recognizes during targeting

## Assistant

All edits look correct. Let me do a quick summary of what was done:

---

**Batch 4 complete.** Here's what was done:

**Cards fixed (8 cards, 10 `Custom(...)` → `create_token(...)` swaps):**

| Card | Set | Change |
|------|-----|--------|
| Guarded Heir | FDN | ETB → `create_token("3/3 Knight", 2)` |
| Prideful Parent | FDN | ETB → `create_token("1/1 Cat", 1)` |
| Resolute Reinforcements | FDN | ETB → `create_token("1/1 Soldier", 1)` |
| Release the Dogs | FDN | Spell → `create_token("1/1 Dog", 4)` |
| Dwynen's Elite | FDN | ETB → `create_token("1/1 Elf Warrior", 1)` |
| Dragonmaster Outcast | FDN | Upkeep → `create_token("5/5 Dragon with flying", 1)` |
| Searslicer Goblin | FDN | End step → `create_token("1/1 Goblin", 1)` |
| Clachan Festival | ECL | ETB → `create_token("1/1 Kithkin", 2)` + activated `Cost::pay_mana("{4}{W}")` + `create_token("1/1 Kithkin", 1)` |

**Tests added:** `framework_create_token_effect`, `framework_create_token_with_keyword`

**249 tests passing** (52 + 18 + 160 + 0 + 19).

**Deferred:** Food tokens (artifact, not creature — needs engine change), Faebloom Trick (compound effect), all token copies, variable-count tokens. These findings are documented in the work queue.
