Reanimation has always been black's domain, paid for with self-mill, discard, and a graveyard you stock yourself. This angel inverts the proposition: she steals from someone else's bin, and she does it on a repeatable tap rather than a single spell that resolves once and leaves. That choice reshapes the whole exchange. You do not need to enable the reanimation; your opponent does it for you every time a creature dies and lands in their yard. The randomness is the tax. You cannot snipe their best fatty, you take what the deck gives, which keeps a recurring theft engine from collapsing into a deterministic tutor. The 4/7 frame with flying and vigilance is sized for the long game the ability demands. Seven mana and a tap means she will not return value until the turn after she lands, so the toughness and vigilance let her hold the ground and the air while the engine spins up over multiple turns. The Mardu color spread is deliberate: red and white rarely touch reanimation, so reaching across all three colors signals a grind tool rather than a fast-combo piece. The longer a game runs, the more graveyards she has to plunder, and the value compounds with every dead creature an opponent leaves behind rather than arriving in a single explosive turn.
