Toph, the First Metalbender + Toph, Hardheaded Teacher + Overgrown Estate + Simic Growth Chamber

Toph, the First Metalbender

Toph, Hardheaded Teacher

Overgrown Estate

Simic Growth Chamber

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Simic Growth Chamber.
3. Resolve the artifact spell.
4. Activate Overgrown Estate by sacrificing Simic Growth Chamber.
5. When Simic Growth Chamber dies, Toph, Hardheaded Teach triggers, returning Simic Growth Chamber from your graveyard to the battlefield tapped.
6. When Simic Growth Chamber enters, it triggers, returning the artifact cast in step 1 from the battlefield to your hand, as it's a land due to Toph, the First Metalbender.
7. Resolve the Overgrown Estate ability
8. Repeat.

This clever loop turns zero-mana artifact casting into an engine for infinite resources by weaving together land-type manipulation and recursive triggers. Toph, the First Metalbender does the crucial heavy lifting by turning your nontoken artifacts into lands, allowing Simic Growth Chamber's bounce ability to target your recast artifact. Meanwhile, Toph, Hardheaded Teacher keeps the land-animation triggers flowing as you recast your spells, and Overgrown Estate provides a sacrifice outlet to feed the loop. When you sacrifice Simic Growth Chamber for life, its death triggers return it to the battlefield, where its entry trigger bounces the artifact back to your hand to start the cycle anew.
