Fell Beast of Mordor
Devour is usually a red-green mechanic: you consolidate a board into a single oversized attacker and hope it connects. Bending it into black flips the payoff structure entirely. The counters here are not just size, they are a resource the drain reads off of twice, once on entry and once on every attack, so each creature you sacrifice becomes a repeatable Blood Artist-style life swing rather than a one-time buff. That doubling is the design logic worth sitting with. A wide devour inflates the body, but the entry-drain already cashes those counters in as a life swing before combat happens, meaning a token board can convert into a lethal drain even if the flyer never gets in. The flying is what closes the loop: a 3/3 base that scales with the sacrifice and slips past ground blockers turns the drain into a recurring clock rather than a single fragile payoff. Where a red-green devour creature spends its sacrificed board on one attacker that dies to the first removal spell, this one has already banked a drain on entry whether or not it survives, so the fodder is never fully wasted. The tension the card resolves is old to black: aristocrat decks have always wanted their sacrificed bodies to do work on the way out. This attaches that work to a repeatable evasive threat instead of a pile of one-shot death triggers, and lets the drain scale with the same fodder that grew the body.
