Springheart Nantuko + Mutable Explorer + Tiller Engine + Tireless Provisioner

Springheart Nantuko

Mutable Explorer

Tiller Engine

Tireless Provisioner

How it works

1. Play a land.
2. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create a token copy of Mutable Explorer.
3. When the Mutable Explorer token enters, it triggers, creating a Mutavault land token that enters tapped.
4. When the Mutavault token enters, Springheart Nantuko, Tiller Engine and Tireless Provisioner trigger.
5. Resolve the Tiller Engine trigger, untapping the Mutavault token.
6. Holding priority, activate the Mutavault token by tapping it, adding C.
7. Resolve the Tireless Provisioner trigger, creating a Treasure token.
8. Holding priority, activate the Treasure by tapping and sacrificing it, adding .
9. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Mutable Explorer.
10. Repeat from step 3.

This intricate loop transforms a single land drop into an endless cascade of creature tokens and resources by leveraging a clever chain of triggers. When you play a land, Springheart Nantuko uses its landfall ability to copy Mutable Explorer, whose own entry into the battlefield generates a Mutavault land token. That newly arriving Mutavault immediately awakens Tiller Engine to untap it and Tireless Provisioner to mint a Treasure, providing the exact mana needed to pay for Springheart Nantuko's recurring cost.
