Junji, the Midnight Sky

A death trigger normally cedes timing to the opponent: they decide whether the payoff ever fires by deciding whether to kill the creature at all. This one closes that loophole by making the body genuinely worth killing and then taxing the kill either way. Left alone, a 5/5 flying menace is a clock most decks cannot profitably block; deal with it, and you either strip two cards and two life from each opponent or reanimate the best non-Dragon in any graveyard for a two-life cost. The modal choice is the whole design: a single card becomes a threat that converts its own removal into value regardless of what the opponent picks. Against control, the discard mode slips under counterspells and gutts a defensive hand; against creature decks, the reanimation mode turns their board wipes and combat losses into your finisher. The non-Dragon clause is the quiet balancing lever, keeping the reanimation mode from simply looping back another copy of a dragon engine and pointing it instead at whatever oversized creature has already hit a graveyard. What connects it to black's older "cannot be answered cleanly" threats is not a recursion loop in the Gravecrawler sense: it is a body priced so that every answer costs the answerer something, no matter which direction they choose to solve it.
