Legion Extruder

Two mana buys a Shock stapled to a permanent, and the enters trigger is the honest half of the deal: it does something the turn it resolves whether or not the sacrifice engine ever matters, clearing a blocker or closing out a player. That engine is where the design earns its shape. The activated ability converts spent artifacts into 3/3 bodies, so the card wants to live at the back end of a token or Treasure economy, turning permanents that have already done their job into board presence. The key restriction is that the sacrifice is a cost, not a bonus, which forces a real choice on each expendable artifact: a Treasure can pay for a spell or it can become a Golem, never both. It rewards volume, not double-dipping, and because the ability taps the artifact, it makes at most one Golem per turn barring untap effects; the ceiling is tied to how much disposable junk the rest of the deck manufactures. Both halves of the card point the same way, though. The entry burn is a proactive threat, and the token maker is a resilience valve that rebuilds after a sweeper, converting the artifacts that survive into fresh attackers. It reads like a mediocre burn spell in a vacuum and like a genuine payoff next to the machinery that produces steady sacrifice fuel; the card only makes sense as the exhaust port of an artifact economy, not as a standalone piece.
