The Master, Multiplied

Kiki-Jiki, Mirror Breaker

Izzet Chemister

Time Warp

How it works

1. Cast Time Warp by paying 3, causing you to take an extra turn after this one.
2. Activate Kiki-Jiki by tapping it, creating a token copy of Izzet Chemister.
3. Activate the Izzet Chemister token's first ability by paying and tapping it, exiling Time Warp from your graveyard.
4. At the beginning of your end step, Kiki-Jiki triggers, but you cannot sacrifice the Izzet Chemister token due to The Master.
5. On your next turn, activate the Izzet Chemister token's last ability by paying 1, tapping it, and sacrificing it, casting the exiled spell without paying its mana cost.
6. Resolve that spell, causing you to take an extra turn after this one.
7. Repeat from step 2.
