Soulherder blinks Eternal Witness at end step, returning Time Stretch from the graveyard to hand; the next turn is yours again, and the loop never breaks. The shell is Bant flicker — Brago, King Eternal and Roon of the Hidden Realm are the natural commanders, both of whom can replace Soulherder as the blink engine if needed.

Result

Infinite turns; Lock

Variations

Cheaper, tighter, alternate lines

Conjurer's Closet or Erratic Portal can substitute for Soulherder as the blink trigger, though Closet is sorcery-speed and Erratic Portal requires one mana each iteration. Nexus of Fate is a direct swap for Time Stretch — cheaper at 5 mana and it shuffles back into the library instead of hitting the graveyard, cutting Eternal Witness out entirely and collapsing the combo to 2 pieces.
