Kiki-Jiki, Mirror Breaker

Eternal Witness

Time Walk

How it works

1. Cast Time Walk by paying 1, 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 Time Walk from your graveyard to your hand.
4. Repeat each turn.
