Kykar, Zephyr Awakener

Mnemonic Wall

Walk the Aeons

How it works

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