Time Warp grants the extra turn; Ephemerate's rebound does the real work by blinking Eternal Witness twice — once to recover Time Warp, once to recover Ephemerate itself. The loop runs at sorcery speed but costs only 2UUG to start and asks nothing of the battlefield beyond the three pieces, making it a natural fit for Bant value commanders like Chulane, Teller of Tales or Roon of the Hidden Realm that already want all three cards.

Steps

Cast Time Warp by paying its mana cost, causing you to take an extra turn after this one.
Cast Ephemerate by paying , blinking Eternal Witness and exiling Ephemerate.
When Eternal Witness enters, it triggers, returning Time Warp from your graveyard to your hand.
Move to your next turn. At the beginning of your upkeep, Ephemerate's rebound ability triggers, causing you to cast it from exile without paying its mana cost.
Resolve Ephemerate, blinking Eternal Witness.
When Eternal Witness enters, it triggers, returning Ephemerate from your graveyard to your hand.
Repeat.

Result

Infinite turns; Lock

Variations

Cheaper, tighter, alternate lines

Heidar's Wrath is unnecessary overhead — Time Warp is the cleanest extra-turn spell here, but Temporal Manipulation or Part the Waterveil slot in identically if redundancy is needed. Conjurer's Closet or Erratic Portal can substitute for Ephemerate in a pinch, though losing rebound means a new blink source is needed each turn; the real upgrade is adding a tutor like Eladamri's Call or Green Sun's Zenith to fetch Eternal Witness and assemble faster.
