Kykar, Zephyr Awakener

Izzet Chronarch

Time Walk

How it works

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