Toph, the First Metalbender + Toph, Hardheaded Teacher + Lithatog + Arid Archway

Toph, the First Metalbender

Toph, Hardheaded Teacher

Lithatog

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 Lithatog 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 Lithatog ability
8. Repeat.

This clever loop transforms a humble zero-mana artifact into a perpetual motion machine by weaponizing the unique rules interaction between Toph, the First Metalbender and Arid Archway. Because Toph turns all your nontoken artifacts into lands, Arid Archway's entry trigger doesn't just bounce a random property—it specifically targets that artifact-turned-land and picks it back up into your hand. Meanwhile, Lithatog acts as the hungry sacrifice outlet that triggers Arid Archway's earthbound safety net, sending it to the graveyard only for Toph, Hardheaded Teacher to instantly recursion-loop it back to the battlefield. Every single iteration of this cycle is greased by casting your free artifact and casting spells that trigger Toph, Hardheaded Teacher's earthbending to keep the battlefield primed and your sacrifice fodder infinite.
