Toph, the First Metalbender + Springheart Nantuko + Tireless Provisioner

Toph, the First Metalbender

Springheart Nantuko

Tireless Provisioner

How it works

1. At the beginning of your end step, Toph triggers, animating a land you control that enters the battlefield untapped.
2. During your next turn, cast Springheart Nantuko for its bestow cost by paying 1, attaching it to an animated land.
3. Play a land. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create a copy of the land it is attached to.
4. When the land token enters, Springheart Nantuko and Tireless Provisioner trigger.
5. Holding priority, activate the land token by tapping it, adding at least 1.
6. Resolve the Tireless Provisioner trigger, creating a Treasure token.
7. Activate the Treasure by tapping and sacrificing it, adding .
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a copy of the land it is attached to.
9. Repeat from step 4.

This delightfully clever loop transforms your ordinary artifacts into land-copying engines, starting with Toph, the First Metalbender turning all your nontoken artifacts into lands. Once Springheart Nantuko is bestowed onto one of those newly minted lands, dropping any new land kicks off a cascading chain reaction. Tireless Provisioner steps in to fund the copying process by spitting out Treasures whenever a land enters, providing the exact mana needed to keep Springheart Nantuko's landfall trigger multiplying your land tokens indefinitely.
