Molder Slug
An artifact-eater built for an era made of artifacts. On a plane where nearly every permanent was metal, a body this size that forces each player to feed it an artifact every upkeep was less a hatebear than a slow-motion artifact apocalypse, and the symmetry is what gives it teeth: it eats your stuff too, so it belongs in a green shell that runs few artifacts itself while the opponent drowns in them. The sacrifice clause is the player's choice, not the controller's, so it never functions as a precision answer to any single key piece; it is attrition, not removal, grinding both boards down to whoever has the fewer artifacts to lose. The 4/6 frame matters more than it looks: it sits above most of the era's beaters and behind a wall that the slug's own engine eventually clears for it, since the opponent runs out of fodder first. That patience is the whole pitch. Where a one-shot artifact destruction spell answers a single problem, this one keeps answering until the table is bare, then attacks into the wreckage. It asks you to be the player who can afford to keep paying the tax, which in a metal-heavy field is its own kind of color-pie statement: green's answer to artifacts is not to shatter one, but to make owning them a liability turn after turn.
