2606: assert!(!game.state.battlefield.get(opp_bear_id).unwrap().has_keyword(KeywordAbilities::TRAMPLE));
Now let me check that the engine compiles before fixing cards:
cd /mnt/dest-btrfs/home/jc/src/mage/mtg-rl && cargo check -p mtg-engine 2>&1 Checking mtg-engine v0.1.0 (/mnt/dest-btrfs/home/jc/src/mage/mtg-rl/mtg-engine)
Finished `dev` profile [unoptimized + debuginfo] target(s) in 1.10sEngine compiles. Now let me fix the cards. Let me fix them all with sed:
cargo test -p mtg-engine --lib -- fight_and_bite_effects fight_auto_selects_creatures 2>&1 Compiling mtg-engine v0.1.0 (/mnt/dest-btrfs/home/jc/src/mage/mtg-rl/mtg-engine)
Finished `test` profile [unoptimized + debuginfo] target(s) in 2.06s
Running unittests src/lib.rs (target/debug/deps/mtg_engine-fa37b04e04026fe5)
running 2 tests
test game::tests::fight_and_bite_effects ... ok
test game::tests::fight_auto_selects_creatures ... ok
test result: ok. 2 passed; 0 failed; 0 ignored; 0 measured; 161 filtered out; finished in 0.00sTests pass. Now let me fix the cards. Let me fix each one:
1. FDN: Bite Down — pure bite spell
sed -i 's|vec!\[Effect::Custom("Target creature you control deals damage equal to its power to target creature or planeswalker you don'\''t control.".into())\]|vec![Effect::bite()]|' mtg-cards/src/sets/fdn.rs(empty result)
2. FDN: Affectionate Indrik — ETB fight trigger
sed -i 's|vec!\[Effect::Custom("When Affectionate Indrik enters the battlefield, you may have it fight target creature you don'\''t control.".into())\],|vec![Effect::fight()],|' mtg-cards/src/sets/fdn.rs && sed -i 's|TargetSpec::None),|TargetSpec::Creature),|' mtg-cards/src/sets/fdn.rs(empty result)
Wait, sed replacing TargetSpec::None), could hit many places. Let me check.
grep -n "TargetSpec::Creature)," mtg-cards/src/sets/fdn.rs | head -20618: TargetSpec::Creature), 631: TargetSpec::Creature), 657: TargetSpec::Creature), 680: TargetSpec::Creature), 693: TargetSpec::Creature), 721: TargetSpec::Creature), 735: TargetSpec::Creature), 767: TargetSpec::Creature), 780: TargetSpec::Creature), 817: TargetSpec::Creature), 838: TargetSpec::Creature), 851: TargetSpec::Creature), 872: TargetSpec::Creature), 886: TargetSpec::Creature), 926: TargetSpec::Creature), 942: TargetSpec::Creature), 969: TargetSpec::Creature), 995: TargetSpec::Creature), 1010: TargetSpec::Creature), 1027: TargetSpec::Creature),
That sed replaced ALL TargetSpec::None), with TargetSpec::Creature), — that's a disaster. Let me undo that.
git checkout mtg-cards/src/sets/fdn.rsUpdated 1 path from the index
Let me be much more careful with the edits. I'll use specific context in sed or read/edit individual cards.
sed -i 's|vec!\[Effect::Custom("Target creature you control deals damage equal to its power to target creature or planeswalker you don'\''t control.".into())\]|vec![Effect::bite()]|' mtg-cards/src/sets/fdn.rs(empty result)
Now for Affectionate Indrik, I need to change both the Effect and the TargetSpec on surrounding lines. Let me use a more precise approach:
grep -n "Affectionate Indrik" mtg-cards/src/sets/fdn.rs382: registry.register("Affectionate Indrik", affectionate_indrik, "FDN");
5243: CardData { id, owner, name: "Affectionate Indrik".into(), mana_cost: ManaCost::parse("{5}{G}"),
5250: "When Affectionate Indrik enters the battlefield, you may have it fight target creature you don't control.",
5252: vec![Effect::Custom("When Affectionate Indrik enters the battlefield, you may have it fight target creature you don't control.".into())],sed -i '5252s|.*| vec![Effect::fight()],|' mtg-cards/src/sets/fdn.rs && sed -i '5253s|TargetSpec::None|TargetSpec::Creature|' mtg-cards/src/sets/fdn.rs(empty result)
3. FDN: Felling Blow — +1/+1 counter + bite
grep -n "Felling Blow" mtg-cards/src/sets/fdn.rs490: registry.register("Felling Blow", felling_blow, "FDN");
6012: CardData { id, owner, name: "Felling Blow".into(), mana_cost: ManaCost::parse("{2}{G}"),<tool_use_error>Sibling tool call errored</tool_use_error>
sed -i '6017s|.*| vec![Effect::add_p1p1_counters(1), Effect::bite()],|' mtg-cards/src/sets/fdn.rs && sed -i '6018s|TargetSpec::None|TargetSpec::Creature|' mtg-cards/src/sets/fdn.rs(empty result)
4. ECL: Assert Perfection — boost + fight
sed -i "s|Effect::Custom(\"It fights target creature you don't control.\".into())|Effect::fight()|" mtg-cards/src/sets/ecl.rs(empty result)
5. TDM: Piercing Exhale — pure fight
sed -i "s|Effect::Custom(\"Target creature you control fights target creature you don't control.\".into())|Effect::fight()|g" mtg-cards/src/sets/tdm.rs(empty result)
That should have fixed both Piercing Exhale (pure fight) and Knockout Maneuver (counter + fight). Let me verify:
grep -n "fight\|bite\|Fight\|Bite" mtg-cards/src/sets/tdm.rs | head -20259: registry.register("Teval, Arbiter of Virtue", teval_arbiter_of_virtue, "TDM");
1212: // Sorcery {2/G}{2/U}{2/R}. Double P/T of your creature, then fight.
1215: abilities: vec![Ability::spell(id, vec![Effect::Custom("Double target creature's P/T, then it fights target creature you don't control.".into())], TargetSpec::Creature)],
1228: // Sorcery {2}{G}. +1/+1 counter on your creature, then it fights opponent's creature.
1231: abilities: vec![Ability::spell(id, vec![Effect::add_p1p1_counters(1), Effect::fight()], TargetSpec::Creature)],
1252: // Instant {1}{G}. Behold Dragon. Your creature fights target. If beheld, surveil 2.
1255: abilities: vec![Ability::spell(id, vec![Effect::fight()], TargetSpec::Creature)],
3522:fn teval_arbiter_of_virtue(id: ObjectId, owner: PlayerId) -> CardData {
3523: CardData { id, owner, name: "Teval, Arbiter of Virtue".into(),Lines 1231 (Knockout Maneuver) and 1255 (Piercing Exhale) are fixed. Dragonclaw Strike (1215) is still Custom (expected — it has "double P/T" which we can't implement).
Now let me check if there are any remaining fight customs to handle:
grep -n "Custom.*fight\|Custom.*deals damage equal to its power" mtg-cards/src/sets/fdn.rs mtg-cards/src/sets/ecl.rs mtg-cards/src/sets/tdm.rs mtg-cards/src/sets/tla.rsmtg-cards/src/sets/fdn.rs:3007: vec![Effect::Custom("Choose one: Search for basic land; or target creature you control fights target creature you don't control.".into())],
mtg-cards/src/sets/fdn.rs:6796: vec![Effect::Custom("Target creature you control gets +X/+X until end of turn. Then it fights up to one target creature you don’t control.".into())],
mtg-cards/src/sets/ecl.rs:2173: vec![Effect::Custom("Choose two: copy target Kithkin you control; target player creates 1/1 Kithkin token; target creature +3/+3 until EOT; target creature you control fights target creature an opponent controls.".into())],
mtg-cards/src/sets/tdm.rs:1215: abilities: vec![Ability::spell(id, vec![Effect::Custom("Double target creature's P/T, then it fights target creature you don't control.".into())], TargetSpec::Creature)],
mtg-cards/src/sets/tdm.rs:2995: vec![Effect::Custom("Target Dragon you control deals damage equal to its power to any target.".into())],Good. The remaining ones are:
These are all correctly deferred. Let me compile and test:

Now update the per-set remediation docs. Let me check the current state of the remediation docs for the affected cards:
368:- [ ] **Bite Down** -- What works: nothing functional. What's broken: `Effect::Custom("Target creature you control deals damage equal to its power...")`.397:- [ ] **Assert Perfection** — What works: `boost_until_eot(1, 0)`. What's broken: `Effect::Custom("fights target creature")`.292:- [ ] **Knockout Maneuver** — Sorcery {2}{G}. What works: AddCounters +1/+1. What's broken: `Effect::Custom("Target creature you control fights target creature you don't control.")`.
323:- [ ] **Piercing Exhale** — Instant {1}{G}. All Custom: fight effect.Now let me check for Affectionate Indrik and Felling Blow in fdn-remediation.md:
No matches found
Affectionate Indrik and Felling Blow are not in the remediation doc. That's fine — the remediation docs may not be exhaustive. Let me just fix the ones I found. Let me update the docs:1. FDN remediation: mark Bite Down as fixed
2. ECL remediation: mark Assert Perfection as fixed
3. TDM remediation: mark Knockout Maneuver and Piercing Exhale as fixed
4. ROADMAP.md: update fight/bite status

+t's strongest creature. Fixed 6 cards. Remaining fight/bite cards blocked by modal spells (Batch 11), X-cost (Batch 15), or complex compound effects.
Good question. Let me check the Java implementation to see if fight/bite actually works differently.

Now I can see the key difference. In the Java implementation:
Fight (FightTargetsEffect):
creature1.fight(creature2, source, game) which does mutual damageBite (DamageWithPowerFromOneToAnotherTargetEffect):
Also has two explicit targets: target 1 (your creature) and target 2 (opponent's creature/player)
The first target's power determines the damage
The damage is dealt to the second target
Can also target players (not just creatures)
Our implementation deviates significantly — we're auto-selecting the controller's strongest creature and the opponent's strongest creature instead of letting the player choose both targets explicitly, which is how the Java version actually works.
The real constraint here is that our TargetSpec system only supports single-target selection, so we can't properly model the two-target pattern that fight mechanics require. I need to update the ROADMAP to clearly document this limitation rather than pretending our auto-selection behavior matches the real rules.
No, it doesn't. The Java implementation is meaningfully different:
Java (FightTargetsEffect):
Java (DamageWithPowerFromOneToAnotherTargetEffect — bite):
Our implementation:
TargetSpecThe core issue is our TargetSpec system only supports one target type per ability, so we can't model the two-target "your creature + their creature" pattern that fight/bite spells actually use. The auto-select-strongest heuristic is a workaround.
For ETB triggers (Affectionate Indrik), it's mostly correct — the source is the creature, and the target is the opponent's creature. But for spells, the player should be choosing which creature fights, not auto-picking strongest.
Let me update the ROADMAP to be honest about this limitation:
Also update the phase summary:
And update the work queue similarly:
The docs now accurately describe the gap. To summarize: the Java implementation uses proper two-target selection where the player chooses both creatures, while our engine auto-picks the strongest creature as a heuristic since TargetSpec doesn't support multi-target with different filters. The damage mechanics (mutual for fight, one-way for bite) are correct — it's the creature selection that's simplified.

The core issue is that our TargetSpec system only supports a single target type, but fight/bite spells need two targets: "target creature you control" and "target creature you don't control".
Let me think about what needs to change:
We need a way to specify two different targets in one ability
The execute_effects function receives a targets: &[ObjectId] array - we could use this with convention: targets[0] = your creature, targets[1] = opponent's creature
We need a TargetSpec variant that describes two targets
Looking at the current enum, there's already a Multiple variant for multiple targets of the same type, but we need something different for two distinct target types - maybe a TwoTargets variant that can hold two different TargetSpec values.
The simplest path forward seems to be adding CreatureYouControl and OpponentCreature variants, then creating a Pair variant that can combine any two target specs together for cases like fight mechanics. But this means I need to trace through how targets are currently selected and passed through the system to understand what changes are needed in the targeting flow.
Let me understand how targets flow through the system so I can design the fix properly.

2201: let stack_item = crate::zones::StackItem {
2203: kind: crate::zones::StackItemKind::Spell { card: murder },Now I have a good picture of what needs to be done. Let me categorize the cards:
Fight cards (two creatures deal damage to each other equal to their power):
TDM: Teval, Arbiter of Virtue (line 1255) — "Target creature you control fights target creature you don't control."
TDM: line 1231 — "+1/+1 counter on your creature, then it fights opponent's creature."
TDM: line 1215 — "Double target creature's P/T, then it fights target creature you don't control."
ECL: line 1799 — "Target creature +1/+0, then fights opponent's creature."
FDN: Affectionate Indrik (line 5254) — "When Affectionate Indrik enters the battlefield, you may have it fight target creature you don't control."
One-way damage cards (creature deals damage without fighting back):
6. FDN: line 6019 — "Put a +1/+1 counter on target creature you control. Then that creature deals damage equal to its power to target creature an opponent controls."
7. FDN: line 3009 — Modal effect with fight option
8. FDN: Bite Down (line 2307) — "Target creature you control deals damage equal to its power to target creature or planeswalker you don't control."
9. TDM: line 2995 — "Target Dragon you control deals damage equal to its power to any target."
Now I'm cross-referencing the batch assignments with what I'm actually finding in the grep results. The work queue shows Bite Down and several fight cards for Batch 8, but I need to verify the exact line numbers and card names match up with what's in the codebase.
Looking through the fight mechanics more systematically, I'm seeing a range of implementations across the sets. There's the straightforward fight effect, variations with stat boosts applied before fighting, modal options that include fight as one choice, and some compound mechanics that layer multiple effects together. Some of these are marked as too complex for the current batch, so I need to identify which ones are actually doable and which ones should be deferred.
I see — cast_spell sets targets: vec![] — no targets are selected. Let me look at where targets actually get chosen. Let me search for where item.targets gets populated.
