Kiki-Jiki, Mirror Breaker

Mnemonic Wall

Time Warp

How it works

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