Toph, the First Metalbender + Toph, Hardheaded Teacher + Woe Strider + Simic Growth Chamber

Toph, the First Metalbender

Toph, Hardheaded Teacher

Woe Strider

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 Woe Strider 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 Woe Strider ability
8. Repeat.

This loop turns zero-mana artifacts into a relentless engine of sacrifice and landfall by weaving together a clever set of type-changing and recursion effects. Thanks to Toph, the First Metalbender, your nontoken artifacts are treated as lands, allowing Simic Growth Chamber to bounce them back to your hand when it enters the battlefield. Meanwhile, Woe Strider provides a reliable outlet to sacrifice those animated land-artifacts, and whenever your permanents hit the graveyard, Toph, Hardheaded Teacher's ongoing presence steps in to return Simic Growth Chamber to the battlefield ready to restart the cycle.
