Springheart Nantuko + Mutable Explorer + Amulet of Vigor + Nissa, Resurgent Animist

Springheart Nantuko

Mutable Explorer

Amulet of Vigor

Nissa, Resurgent Animist

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 Nissa 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 Nissa trigger, adding .
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Mutable Explorer.
9. Repeat from step 3.

This fascinating loop turns a simple land drop into an engine of endless replication by chaining creature copies and land generation together. Whenever your lands or tokens enter, Springheart Nantuko uses its landfall ability to clone Mutable Explorer, whose changeling nature ensures it keeps spawning Mutavault tokens. Meanwhile, Amulet of Vigor steps in to untap those incoming Mutavault tokens so you can immediately tap them for colorless mana, which combines with the color-fixing mana generated by Nissa, Resurgent Animist to perpetually fund Springheart Nantuko's replication cost.
