Corpse Knight

The trigger is the thing to read carefully: it fires on creatures, not permanents broadly, and on other creatures that enter under your control. That narrows the payoff and sharpens the deckbuilding question. Every mana dork, every recruited hatebear, every reanimated body now pings the whole table for a life each, which turns a go-wide aristocrats shell into a drain engine that does not need a sacrifice outlet to close. The interesting overlap is with token production: a single populate or a swarm-maker converts board development into a hard clock, since each token that enters is a separate loss trigger. Note what it is not, though: the life loss hits each opponent independently, so a wide board in a multiplayer pod scales the drain outward rather than concentrating it, and the 2/2 body means this is a payoff you protect, not one that protects itself. That fragility is the tradeoff for stapling repeatable, untargeted drain onto a two-drop with no evasion and no way to keep itself alive. It sits with the Orzhov engines that reward flooding the board with bodies rather than trading them one for one, and it asks for the specific commitment of a deck built to keep creatures entering turn after turn rather than one that lands a threat and holds.
