Thassa, Deep-Dwelling's end-step exile trigger blinks Eternal Witness, whose enters-the-battlefield trigger puts Time Warp back in hand — then the extra turn starts and the cycle repeats. The Simic shell that runs this is typically a Thassa or Kinnan, Bonder Prodigy deck that already wants both a blink engine and extra-turn spells, so the three pieces arrive together naturally.

Infinite turns; Lock

Cheaper, tighter, alternate lines

Conjurer's Closet replaces Thassa as the blink engine if blue devotion isn't a concern, though it operates only at end step with no activated option. Archaeomancer and Salvager of Secrets are cheaper substitutes for Eternal Witness if green is unavailable or the slot is contested — any creature that retrieves an instant or sorcery on entry closes the loop.
