Whenever a creature an opponent controls dies, put a +1/+1 counter on Yahenni, Undying Partisan.
Sacrifice another creature: Yahenni gains indestructible until end of turn.
Quote from IndigoAjani »Agreed on the mechanics, but it should be noted thst Yahenni's pronouns are they/them. The story explicitly says as much.
Quote from Czarnianshuckle »He should have lifelink, but he is still well designed for his story.
