Brood Butcher

The sacrifice outlet stapled to the body is the whole shape of this thing. The Scion it brings along is the priming charge: a token that becomes the first body you feed into the activation, or a spare colorless mana you cash in for something else while you gather better fodder. From there the -2/-2 ability is a repeatable removal engine, converting your weakest creatures into the opponent's most relevant ones one shrink at a time. With no timing restriction on the activation, it fires at instant speed, so you can ambush an attacker, finish off something already chipped in combat, or stack two activations to drag down a larger threat at the end of a stalled turn. Devoid does the quiet work that this line of Eldrazi designs leaned on: it strips the card of color entirely, so the creature reads as alien on the battlefield while still living in a black-green sacrifice shell and slotting into the aristocrats-adjacent decks that want a mana value five grinder. It was never built to race; it is a midrange piece, the kind that turns a clogged board into a slow vise and asks the opponent to find an answer before their creatures get picked apart one at a time. Less a threat than a machine for outlasting one.
