Kykar, Zephyr Awakener + Walk the Aeons + Timeless Witness

Kykar, Zephyr Awakener

Walk the Aeons

Timeless Witness

How it works

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