Teleportation Circle + Eternal Witness + Capture of Jingzhou

Teleportation Circle

Eternal Witness

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying 3, causing you to take an extra turn after this one.
2. At the beginning of your end step, Teleportation Circle triggers, blinking Eternal Witness.
3. When Eternal Witness enters the battlefield, it triggers, returning Capture of Jingzhou to your hand from your graveyard.
4. Repeat each turn.
