Butcher of Malakir

Take the Grave Pact effect and bolt it onto a body, and you get a sacrifice engine that no longer depends on the rest of your board surviving. Where the enchantment version reads as a static rule everyone has to play around, this one carries its own clock: a 5/4 flier that closes games while it strips the opposing board one creature at a time. The trigger is the entire point of building around it. Each death you control, including the Butcher's own, forces every opponent to sacrifice, so the card rewards a deck that treats its creatures as ammunition: tokens, sacrifice fodder, anything you were happy to lose. Edicts have always been black's answer to hexproof, shroud, and the single threat too big to remove conventionally; this turns that one-shot effect into a recurring tax that fires every time a creature on your side hits the bin. The seven-mana price and the double-black requirement are what keep it from being a casual inclusion: this is a payoff you commit to, not a curve-filler. Pair it with any reliable death stream and the math against a multiplayer table becomes brutal, since one of your tokens dying costs three or four opponents a creature apiece in a single trigger.
