Dread Rider

A body built for the long game masquerading as a finisher. The 3/7 frame is the tell: this is a creature designed to block indefinitely while its activated ability grinds an opponent out of life three points at a time. The engine runs on graveyard attrition, converting dead creatures into life loss, which means it wants a deck already feeding its own bin (chump blockers, aristocrat fodder, anything that dies on schedule). The friction is real and deliberate: each drain costs mana, taps the Rider, and permanently exiles a creature card, so the resource that fuels it shrinks with every activation. Because the fuel is finite, there is no runaway inevitability here; you can only ever squeeze as many drains out of it as your graveyard can supply, and every drain is a card leaving your graveyard forever. As a design it sits in the lineage of black's slow-drain finishers, the ones that ask you to survive rather than race, and it rewards a board state where the game has already stalled into a grind. The reach it provides matters most against decks that have run out of pressure and need you to eventually run out of resources; the Rider is happy to trade its own graveyard, one card at a time, for the last chunk of an opponent's life total.
