Malamet Veteran

The body pays for itself before the ability ever comes online: a 5/4 trampler is a fair beater on rate alone, which matters because everything the design offers on top is back-loaded. The descend clause gates the attack trigger behind a stocked yard, so until you get there you are simply swinging with an honest green threat and nothing more. Once the graveyard fills, every attack seeds a +1/+1 counter onto any creature you choose, and that open target is the point of building around it. You can grow an unblocked evader, push a token past a chump, or feed the counters back into the Veteran to turn a trampling body into a fast clock. It sits in the green lineage of creatures that reward a satisfied deckbuilding condition with slow board growth: a payoff, not an engine, since it does nothing to advance descend on its own. That last fact is the real constraint. Nothing here fuels the graveyard, so it wants a shell already leaning on self-mill or grinding attrition rather than one hoping to trip the switch mid-combat. The rate is a fair floor; the upside is genuine but contingent on a game that has run long enough to bury cards. You want the yard already loaded when this attacks, not a reason to start loading it.
