Toph, the First Metalbender + Toph, Hardheaded Teacher + Thermopod + Simic Growth Chamber

Toph, the First Metalbender

Toph, Hardheaded Teacher

Thermopod

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 Thermopod 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. Repeat.

This clever loop transforms your battlefield into an engine by letting Toph, the First Metalbender redefine your nontoken artifacts as lands, turning ordinary zero-mana artifacts into playable bouncing fodder. When you cast that artifact, Toph, Hardheaded Teacher triggers to earthbend Simic Growth Chamber into a creature, making it vulnerable to sacrifice. You then feed that animated bounce-land to Thermopod for red mana, triggering its death-return safety net so it slides right back onto the battlefield. When Simic Growth Chamber re-enters, its own trigger forces you to return a land to your hand—and because Toph, the First Metalbender makes your zero-cost artifact a land, it bounces right back to your hand, ready to be recast endlessly for infinite mana, storm, and triggers.
