Springheart Nantuko + Mutable Explorer + Parallel Lives + Tireless Provisioner

Springheart Nantuko

Mutable Explorer

Parallel Lives

Tireless Provisioner

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 clever loop turns a single land drop into an explosive chain reaction, fueled entirely by how land tokens interact with landfall. Whenever a land enters, Tireless Provisioner generates Treasures to pay for Springheart Nantuko's bestowed landfall ability, which copies creatures while Parallel Lives doubles every single token created along the way. Because Mutable Explorer has changeling and enters the battlefield to create tapped Mutavault tokens, those new lands immediately trigger the cycle all over again, compounding into an unstoppable cascade of infinite mana, tokens, and creature entries.
