Morbid Opportunist

Death-triggered card draw is old ground, but most of it snowballs: Grim Haruspex reads every death at once, Midnight Reaper charges you life for the privilege, and either can turn a board wipe into a fistful of cards. This design refuses that. However many creatures die in a single turn (a wrath, an alpha-strike trade, a mass sacrifice), the trigger resolves for exactly one card. The cap is the entire tradeoff: no life payment, no per-death multiplier, because one death and twenty deaths pay out identically. The consequence is that it wants attrition spread across turns rather than one explosive death spree, which quietly reshapes how you sequence: holding a trade or a sacrifice until next turn is often correct where an uncapped engine would want everything to die immediately. Crucially, the trigger reads every other creature that dies, not just yours, so a removal-heavy opponent keeps it fed too. Its three toughness is defensive by intent, built to block and grind rather than pressure anything, and it shrugs off the small attackers of the early turns it wants to draw through. Removal answers it, of course, but durability was never the point: a cheap creature that converts one death per turn into a card has already traded up before it dies. The once-per-turn limit is what lets that advantage arrive without asking anything of you in return.
