Izzet Chemister + Helm of the Host + Time Walk

Izzet Chemister

Helm of the Host

Time Walk

How it works

1. Cast Time Walk 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 Walk 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.

This Vintage-legal loop hinges on leveraging Izzet Chemister's ability to squirrel away key spells, using its haste and sacrifice-to-cast mechanics to repeatedly break the game's turn structure. By equipping it with Helm of the Host, you guarantee a fresh, non-legendary token copy every combat step to replace the one you'll need to sacrifice. That fresh token then exiles and subsequently casts Time Walk from your graveyard for free, granting you an endless sequence of extra turns to keep the cycle spinning infinitely.
