Springheart Nantuko + Mutable Explorer + Tireless Provisioner + Doubling Season

Springheart Nantuko

Mutable Explorer

Tireless Provisioner

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 Tireless Provisioner each trigger twice.
6. Resolve the Tireless Provisioner triggers, creating two Treasure tokens.
7. Holding priority, activate the Treasures by tapping and sacrificing them, adding 1.
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
9. Repeat from step 3.

This engine transforms a single land drop into an explosive cascade of perpetual growth, anchored by Springheart Nantuko bestowing its landfall copying power upon our board. Mutable Explorer fuels the loop by immediately spawning Mutavault land tokens upon entry, which in turn trigger Tireless Provisioner to continuously manufacture the mana needed to keep paying for the Nantuko's ability. Meanwhile, Doubling Season supercharges every single step by doubling all token creation, turning every iteration into a compounding avalanche of explorers, lands, treasures, and mana.
