Teleportation Circle blinks Eternal Witness at end of turn, and Eternal Witness recovers Capture of Jingzhou from the graveyard so it can be cast again next turn for 3UU. The loop asks for five mana every turn cycle and two specific permanents in play, so the shell needs ramp and protection — Bant Chulane, the Teller of Tales, and Roon of the Hidden Realm lists are the natural homes.

Variations

Cheaper, tighter, alternate lines

Day's Undoing and Time Warp are cheaper extra-turn spells, but Capture of Jingzhou is the cleanest five-mana target here because it works without needing creatures to attack. Conjurer's Closet replaces Teleportation Circle at the same cost if the enchantment is removed, though it only triggers once at end of turn rather than offering the flexibility of instant-speed blinks elsewhere in the deck.
