Ogre Marauder

Every attack forces a choice that always costs the defender something: sacrifice a creature or open the gates. That's the design tension this body lives inside. With three power on a one-toughness frame, the 3/1 is built to die to anything that blocks it, but the trigger means it rarely has to find out. Either the defender feeds it a creature to keep the damage off (often eating a chump they'd rather hold, or worse, a creature worth more than three life) or it slips through unblocked and the three connects. The defender pays in the currency the attacker prefers in the moment, which is the menace of a coercive evasion clause: it doesn't grant unblockability outright, it taxes the right to block.

What keeps it honest is that the sacrifice is the defender's choice, not the attacker's. They pick the creature, so they'll always surrender their least valuable body, and a deck with tokens or expendable blockers can pay the toll cheaply turn after turn. The card is sharpest against decks light on bodies, where every sacrifice is a real card and the alternative is taking the hit. It rewards an aggressive black shell that wants to both reduce the opposing board and push damage, doing two jobs that usually compete for a card slot in one swing.
