Barter in Blood

The edict effect with the bill doubled. Where Diabolic Edict and Chainer's Edict make an opponent give up a single creature of their choice, this collects two, sidestepping the protection that "target creature" removal walks into and forcing a real strip-mine of the board. The catch is symmetry: you pay the same toll, sacrificing two of your own, so the spell was built for decks that either have no creatures to lose or run on bodies they want in the graveyard anyway. That downside is exactly what has kept it alive as a sacrifice-archetype staple rather than a dead-weight removal spell. Tokens, aristocrat fodder, anything with a death trigger or a recursion plan converts the cost into an engine: you were going to sacrifice those creatures regardless, and the spell happens to take two of theirs along the way. The four-mana, double-black requirement keeps it out of splashes and rooted in committed black decks, where the inability to target is the whole point. Hexproof, shroud, protection, indestructible boards: none of them matter to an effect that names no target and grants no choice beyond which two go.
