Sanctifier of Souls

The graveyard is fuel and the board is the engine, and this Cleric is the rare card that wants both pointing the same direction. Its activated ability turns dead creatures into flying bodies one at a time, and each token it makes is itself another creature entering, which feeds the pump trigger and grows the body that built it. That loop is the design's whole personality: a token-maker whose payoff is a token-matters reward, stapled together so the same play pays off twice. The exile cost throttles the spiral: every Spirit you build costs you a body in the yard, so the engine eats its own raw material and has to be refilled rather than looped indefinitely. That tension steers it toward decks that fill the graveyard cheaply and want a sacrifice-and-rebuild rhythm, where a creature dying is not a loss but inventory. The combat math is the part that ages well: across a wide board the pump stacks over the course of a turn, so it can present a real attacker the same turn it untaps mana to make blockers. It belongs to the tradition of white go-wide payoffs that reward each creature individually rather than counting them, but the graveyard clause hands it a recursion axis most of those lack, asking you to husband a resource across several turns instead of just emptying your hand.
