Gearseeker Serpent

Affinity has always pulled toward the cheap end: the keyword's whole reason for being is to make Frogmite and Myr Enforcer arrive ahead of schedule, to flood the board with bodies the moment your artifact count crests. This is the rare design that aims affinity at a finisher instead. A printed seven that an artifact-dense board can deliver several turns early, it bets that the payoff for going wide on artifacts should sometimes be a single threat that ends the game rather than another two-drop. The 5/6 body is sized to survive most of the removal it will run into, and the evasion clause turns it from a beater into a clock you can guarantee connects: hold up that activation and a stalled board stops mattering. The tension the card resolves is what an artifact deck does once it has already committed its mana to the battlefield; the unblockable ability is a sink for the surplus, a way to convert a flooded artifact count into damage on a turn when there is nothing left to deploy. It asks an aggressive shell built to dump artifacts early to keep a top-end finisher in reserve, which is a different deckbuilding question than affinity usually poses.
