Springheart Nantuko + Mutable Explorer + Nissa, Resurgent Animist + Doubling Season

Springheart Nantuko

Mutable Explorer

Nissa, Resurgent Animist

Doubling Season

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 Nissa each trigger twice.
6. Resolve the Nissa triggers, adding 1.
7. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
8. Repeat from step 3.

This loop thrives on a brilliant cascading engine where each land drop pays for its own continuation and spirals wildly out of control. With Doubling Season multiplying every single token—turning single copies of Mutable Explorer and Mutavault tokens into pairs—you quickly flood the board with endless creatures and lands. Meanwhile, Nissa, Resurgent Animist acts as the financial engine of the operation, tapping into the endless landfall triggers to generate all the mana needed to keep Springheart Nantuko paying its bestow-driven copy tax.
