Toph, the First Metalbender + Toph, Hardheaded Teacher + Thermopod + Orzhov Basilica

Toph, the First Metalbender

Toph, Hardheaded Teacher

Thermopod

Orzhov Basilica

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Orzhov Basilica.
3. Resolve the artifact spell.
4. Activate Thermopod by sacrificing Orzhov Basilica.
5. When Orzhov Basilica dies, Toph, Hardheaded Teach triggers, returning Orzhov Basilica from your graveyard to the battlefield tapped.
6. When Orzhov Basilica 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 fueled by a zero-mana artifact, turning Toph, Hardheaded Teacher into a conduit for infinite resources. The key to the whole operation is Toph, the First Metalbender, whose static ability turns your nontoken artifacts into lands, allowing Orzhov Basilica to bounce them back to your hand when it enters the battlefield. Once Thermopod is in play to sacrifice your animated, land-converted artifact after Toph earthbends it into a creature, Orzhov Basilica's death triggers Toph, Hardheaded Teacher to bring it right back—resetting the bounce and netting you infinite red mana, landfall triggers, and storm count along the way.
