Springheart Nantuko + Mutable Explorer + Primal Vigor + Tireless Provisioner

Springheart Nantuko

Mutable Explorer

Primal Vigor

Tireless Provisioner

How it works

1. Play a land.
2. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of Mutable Explorer.
3. When the Mutable Explorer tokens enter, they trigger.
4. Resolve the first Mutable Explorer trigger, creating two Mutavault land tokens that enters tapped.
5. When the Mutavault tokens enter, Springheart Nantuko and Tireless Provisioner each trigger twice.
6. Resolve the Tireless Provisioner triggers, creating two Treasure tokens.
7. Holding priority, activate the Treasures by tapping and sacrificing them, adding 1.
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
9. Repeat from step 3.
