Izzet Chemister + Helm of the Host + Capture of Jingzhou

Izzet Chemister

Helm of the Host

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou 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 Capture of Jingzhou 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 ingenious loop turns a modest Goblin into a temporal engine by leveraging Helm of the Host's combat trigger to continuously churn out non-legendary copies of Izzet Chemister. Each fresh Chemister uses its tap ability to squirrel away the recently resolved Capture of Jingzhou into exile, setting up the ultimate sacrifice. When you finally pop the Chemister token with its second ability, it casts the exiled Capture of Jingzhou for free, immediately granting you another extra turn to untap, replicate your gear, and do it all over again.
