The threat ceiling scales with your board's width, which is the whole tension of this design. As a 0/2 with a tap ability, it is fragile and slow, usually needing to survive a turn before it can tap. But it converts the opponent's graveyard into your battlefield, and the size of what you can steal climbs one for each Ally you control. Empty the yard of mana dorks early; come back later for the bombs once the Ally count catches up. Reanimation in black usually demands a discard-or-mill setup and a reanimation spell, the classic Animate Dead or Reanimate package; this folds the engine into a repeatable tap and routes it entirely at your opponents' graveyards rather than your own. That distinction matters: it is theft, not recursion, so it punishes decks that lean on their bin while contributing nothing if the opposing yard is bare. The Ally-counting clause ties it to the tribal go-wide shell its subtype implies, and the body is built to be hidden behind that board rather than to fight on its own. It is a board-dependent value piece whose payoff is gated behind both untapping and surviving, the kind of grindy engine that rewards a long game and asks you to assemble the surrounding pieces before it earns its keep.
