Eternal Witness

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying 4, causing you to take an extra turn.
2. Activate Kiki-Jiki by tapping it, creating a token copy of Eternal Witness with haste.
3. The token copy of Eternal Witness enters the battlefield, returning Walk the Aeons from your graveyard to your hand.
4. Repeat each turn.
