Armix, Filigree Thrasher

A removal engine dressed as a body, and the trade it asks for is the whole point. The attack trigger scales off two counts at once: artifacts on the battlefield and artifact cards sitting dead in the graveyard, which means every trinket you have already sacrificed or milled keeps working for you. The discard is the cost that keeps the shrink in check; you are paying a card in hand to convert your artifact count into a targeted -X/-X, and the reward grows as the game gets longer and your graveyard fills. That structure makes it a natural anchor for a build that treats artifacts as fuel rather than permanents to protect: the more you throw away, the harder the trigger hits. Partner is what turns a modest 3/2 into an archetype seed rather than a single card. On its own the body is fragile and the trigger needs a table's worth of artifacts to matter, so the design leans on a co-commander to supply the rest of the plan: a value engine, a second color, or a payoff for all the cards being fed to the discard. Read as a piece, it is a rattle-and-hum threat built for a deck that never stops feeding it, where board presence and graveyard count are the same resource seen from two angles.
