Springheart Nantuko + Mutable Explorer + Nissa, Resurgent Animist + Exalted Sunborn

Springheart Nantuko

Mutable Explorer

Nissa, Resurgent Animist

Exalted Sunborn

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 transforms a single land drop into an unstoppable avalanche of resources, anchored by Springheart Nantuko bestowing its cloning power onto Mutable Explorer. Every time a new Mutable Explorer enters, it summons Mutavault tokens that feed back into your mana supply and trigger more copies, while Nissa, Resurgent Animist converts each landfall event into a reliable stream of colored mana. The engine scales exponentially thanks to Exalted Sunborn, whose replacement effect doubles every single token created along the way.
