Toph, the First Metalbender + Toph, Hardheaded Teacher + Zuran Orb + Arid Archway

Toph, the First Metalbender

Toph, Hardheaded Teacher

Zuran Orb

Arid Archway

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Arid Archway.
3. Resolve the artifact spell.
4. Activate Zuran Orb by sacrificing Arid Archway.
5. When Arid Archway dies, Toph, Hardheaded Teach triggers, returning Arid Archway from your graveyard to the battlefield tapped.
6. When Arid Archway 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 Zuran Orb ability
8. Repeat.

This intricate loop turns a zero-mana artifact into an endlessly repeatable engine by leveraging Toph, the First Metalbender to dynamically reclassify your artifacts as lands. With that foundation set, you cast your artifact, triggering Toph, Hardheaded Teacher to earthbend Arid Archway into a living land. You then sacrifice that land to Zuran Orb for life, whose death trigger returns Arid Archway directly to the battlefield to bounce your original artifact back to hand. Repeating this cycle feeds an endless cascade of triggers while continuously fueling your life total and storm count.
