Trash for Treasure

Reanimation that pays its own toll in metal. Where black's graveyard recursion spends life or cards to return a creature, this routes the cost through the artifact graveyard itself: the artifact you sacrifice to cast it can be a depleted Mishra's Bauble, a spent egg, a token, any piece of scrap, and the artifact you return can be the most expensive thing the deck can build toward. The arbitrage is the whole point. Trade a chump artifact for a Wurmcoil Engine, a Blightsteel Colossus, or whatever ceiling the format affords, and you have laundered a junk permanent into a bomb. The design lives entirely on that gap, which is also its discipline: it does nothing in a deck that lacks both the cheap fodder to feed it and the expensive payoff to retrieve. The sacrifice is an additional cost paid on cast, so there is no countering the spell to leave your fodder safe; the artifact is already gone when the return resolves. It runs on cost-conversion reanimation that asks you to seed the graveyard deliberately rather than stumble into value, and it has stayed a build-around curiosity precisely because it demands you assemble both halves of the trade before it reads as anything other than a worse Disentomb for artifacts.
