• [Card Bug] Mana Drain: the mana arrives at the next precombat main phase, skipping a postcombat main phase that comes first ("your next main phase" stored as precombat)

• [Card Bug] Loop shortcut never offered when the period holds mana abilities activated by hand (Treasonous Ogre + Aggravated Assault): the replay activates them in a later step

• [Card Bug] Loop shortcut withheld beside Solitary Confinement: non-continuous static abilities are scanned as reading all turn history

• Imperial Edict: the creature is chosen by the caster at cast time (or the caster's own creature is destroyed), not chosen by the target opponent on resolution (CR 608.2d)

• Tyrant of Discord: ETB offers the caster's own permanents and sacrifices nothing (target opponent never sacrifices at random)

• AI never takes an instant or sorcery with Impulse (0 of 360 picks) or Stock Up (26 of 2,470): dig choices rank by intrinsic_value, which scores any land above every instant or sorcery under mana value 6

• AI casts "if you attacked this turn" cards before combat and then attacks (Storm Fleet Spy: 547 of 1,034 casts; Chart a Course: 418 of 849): nothing in phase-ai reads AttackedThisTurn

  phase-rs/phase#9911 · Filter by author kevinboss opened on Oct 13, 2026

• Once-each-turn permission: a source sacrificed as a cost of the spell it permits keeps its used slot after returning (Zaffai + Village Rites)

• Invulnerability: the spell's prevention sentence is a printed replacement, so casting it does nothing

• Untargeted "remove all … counters from all …" asks for one target and removes from that object only (Oblivion Stone, Corrosion, Temporal Distortion, …)

  phase-rs/phase#9899 · Filter by author matthewevans opened on Oct 13, 2026

• AI spends instants and flash creatures in its own turn, so it almost never reaches the opponent's end step with one castable (0 of 421 casts from an all-instant test deck; 23 of 11,344 casts in saved games)

• AI casts pump and protection instants before blocks or with nothing to answer (1 of 74 pumps after blockers, 7 of 102 protection spells in response): only Effect::Pump reaches the combat-trick timing
