Izzet Chemister + Helm of the Host + Time Warp

Izzet Chemister

Helm of the Host

Time Warp

How it works

1. Cast Time Warp by paying 3, causing you to take an extra turn after this one.
2. At the beginning of your combat phase, Helm of the Host triggers, 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. 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.
5. Resolve that spell, causing you to take an extra turn after this one.
6. Repeat from step 2.
