Banishing Knack gives Steelfin Whale a tap ability to return any artifact to its owner's hand; Sol Ring enters the battlefield, triggers Steelfin Whale's untap ability, and gets recast for 1 to produce two colorless each cycle. The loop lives in blue artifact-adjacent shells — Urza, Lord High Artificer or Jhoira, Weatherlight Captain both have the tutors and payoffs to close immediately.

Retraction Helix is a direct one-for-one swap for Banishing Knack if the slot needs redundancy. The infinite mana is colorless only, so the kill needs a colorless sink — Walking Ballista or Goblin Cannon handles the table; pair the storm count with Grapeshot only if the shell supports red.
