O-Kagachi, Vengeful Kami

The Kami of ancient legend rendered as a five-color punish button: this is a creature whose entire text keys off aggression directed at you. The exile trigger is conditional in a way most beaters are not, because it only fires when the player you connect with attacked you on their previous turn. That single clause reshapes the card from a generic five-color fatty into a reactive threat, one that rewards defensive posture and turns an opponent's own offense into the fuel for a permanent answer. The design leans on the flavor of vengeance rather than dressing it up: you do not initiate the cycle, you retaliate within it. Flying and trample keep the damage reliable so the condition can actually resolve, and exile (rather than destruction) means the removal survives indestructibility and recursion, which matters when a 6/6 is trading blows with resilient boards. The full cost is the honest price for an effect that can strip a nonland permanent every time combat goes your way, and it constrains where the card can live: only a deck already committed to all five colors gets to run it. What makes the whole thing tick is the memory built into the trigger, a rare bit of design that asks the game to track who swung at whom last turn, encoding a grudge into the rules themselves.
