Springheart Nantuko

Mutable Explorer

Amulet of 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 a token copy of Mutable Explorer.
3. When the Mutable Explorer token enters, it triggers, creating a Mutavault land token that enters tapped.
4. When the Mutavault token enters, Springheart Nantuko, Amulet of Vigor and Tireless Provisioner trigger.
5. Resolve the Amulet of Vigor trigger, untapping the Mutavault token.
6. Holding priority, activate the Mutavault token by tapping it, adding C.
7. Resolve the Tireless Provisioner trigger, creating a Treasure token.
8. Holding priority, activate the Treasure by tapping and sacrificing it, adding .
9. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Mutable Explorer.
10. Repeat from step 3.

This ingenious engine spins up an infinite loop entirely off the back of a single land drop, fueled by the mana-generating synergy between Amulet of Vigor and Tireless Provisioner. When you play a land, Springheart Nantuko copies your changeling, Mutable Explorer, which in turn drops a fresh Mutavault token onto the battlefield. Thanks to Amulet of Vigor instantly untapping that new land and Tireless Provisioner kicking in to fund the next payment with a Treasure, you have all the mana and triggers needed to restart the cycle and swarm the board.
