Springheart Nantuko + Mutable Explorer + Tireless Provisioner + Kaya, Geist Hunter

Springheart Nantuko

Mutable Explorer

Tireless Provisioner

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Play a land.
3. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of Mutable Explorer.
4. When the Mutable Explorer tokens enter, they trigger.
5. Resolve the first Mutable Explorer trigger, creating two Mutavault land tokens that enters tapped.
6. When the Mutavault tokens enter, Springheart Nantuko and Tireless Provisioner each trigger twice.
7. Resolve the Tireless Provisioner triggers, creating two Treasure tokens.
8. Holding priority, activate the Treasures by tapping and sacrificing them, adding 1.
9. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
10. Repeat from step 4.

This intricate loop transforms a single land drop into an engine of exponential growth by exploiting token multipliers and recursive changeling triggers. With Kaya, Geist Hunter's minus ability actively doubling all tokens you create this turn, playing a land sets off Springheart Nantuko to clone Mutable Explorer. Because Mutable Explorer creates a Mutavault land token upon entry, every copied changeling instantly triggers a fresh wave of landfalls that power Tireless Provisioner to generate the exact mana needed to keep the Nantuko copying.
