Kykar, Zephyr Awakener + Scholar of the Ages + Time Walk

Kykar, Zephyr Awakener

Scholar of the Ages

Time Walk

How it works

1. Cast Time Walk by paying its mana cost.
2. Kykar triggers, exiling Scholar of the Ages.
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 Scholar of the Ages from exile to the battlefield.
5. When Scholar of the Ages enters, it triggers, returning Time Walk from your graveyard to your hand.
6. Repeat each turn.
