Springheart Nantuko + Mutable Explorer + Nissa, Resurgent Animist + Primal Vigor

Springheart Nantuko

Mutable Explorer

Nissa, Resurgent Animist

Primal Vigor

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 elegant loop relies on Springheart Nantuko's landfall ability to continuously copy creatures, fueled seamlessly by the mana generated from Nissa, Resurgent Animist. Every time a new land or Mutavault token enters the battlefield, Primal Vigor steps in to double your token production, turning a single land drop into an expanding cascade of copies. Meanwhile, Mutable Explorer acts as the perfect engine for this recursive loop by bringing its own Mutavault tokens along upon entry, instantly feeding back into the landfall triggers that keep the entire sequence going.
