Krark-Clan Ironworks sacrifices Sol Ring for two colorless, Sly Requisitioner replaces it with a Servo, the Servo dies for two more, and Salvaging Station untaps itself to rebuy Sol Ring from the graveyard. The loop is self-contained — every cycle produces net colorless mana and fires death, ETB, and LTB triggers in bulk. Black artifact shells like Toshiro Umezawa or Marionette Master commander lists are the natural home, since black already wants to stack artifact sacrifice payoffs.

Cheaper, tighter, alternate lines

Walking Ballista converts the infinite colorless into a table kill; Disciple of the Vault drains the table passively as the loop runs. If Salvaging Station is removed, Scrap Trawler can substitute as the recursion piece by returning Sol Ring off a cheaper artifact death, though that line requires an additional cheap artifact in the bin to anchor it.
