Soul Collector

Theft attached to combat damage, which is a rarer hinge than it looks: most black reanimation wants a body already sitting in a graveyard, but this Vampire builds its own pile by hurting creatures and snatching the corpse the instant one dies. The trigger keys off anything it damaged this turn, and the cleverest line lives in nonlethal combat. Deal partial damage to a creature, then finish it with a removal spell or a sweeper before end of turn, and that creature reroutes onto your side as the original card, permanently, rather than into the bin. There is no token, no copy, no temporary control clause; the dead thing returns under your control intact. That makes it a value engine that scales with the board, since one profitable exchange can convert an opponent's best creature into a permanent gain.

The friction is the body and the way flying cuts against the engine. A 3/4 evader is hard to block, which on offense actually starves the trigger: fewer creatures are eligible to trade with it, so the damage that fuels the recursion most often comes from blocking on the ground or from your own spells doing the lethal work after Soul Collector has chipped in. The morph cost is steep enough that flipping it face up is a real tempo commitment. But the structural idea, lethal damage as a recursion trigger that hands you the corpse rather than dredging your own graveyard, is a clean and underused way to do reanimation.
