Each turn cycle, Roon blinks Eternal Witness at end of step, which returns Time Warp to hand for recasting next turn; the loop is self-sustaining once all three pieces are on board. Bant blink shells — Roon of the Hidden Realm as commander is the obvious home, but any Bant list running Brago, King Eternal — run this as a compact extra-turns engine that only needs 3UU per loop to execute.

Variations
Cheaper, tighter, alternate lines
Archaeomancer and Salvager of Secrets slot in for Eternal Witness if graveyard hate is a concern, trading the flexibility of a generic recursion body for redundancy. Strip Time Warp for Capture of Jingzhou or Temporal Manipulation if the budget calls for it — functionally identical, same mana cost, same result.
