Kykar, Zephyr Awakener + Eternal Witness + Capture of Jingzhou

Kykar, Zephyr Awakener

Eternal Witness

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying its mana cost.
2. Kykar triggers, exiling Eternal Witness.
3. Resolve Capture of Jingzhou, causing you to take an extra turn after this one.
4. At the beginning of your end step, Kykar triggers, returning Eternal Witness from exile to the battlefield.
5. When Eternal Witness enters, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
6. Repeat each turn.
