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

Toph, the First Metalbender

Toph, Hardheaded Teacher

Lithatog

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 Lithatog 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. Resolve the Lithatog ability
8. Repeat.

This elegant engine turns a simple zero-mana artifact loop into an endless cycle of creation and sacrifice, all thanks to Toph, the First Metalbender redefining your non-token artifacts as lands. With that foundation set, casting your artifact triggers Toph, Hardheaded Teacher to animate Orzhov Basilica into an earthbent land creature, which Lithatog can then readily devour as *either* a land or an artifact for its sacrifice buff. When Orzhov Basilica hits the graveyard, its earthbend clause rescues it right back to the battlefield, where its native entry trigger forces you to bounce that original zero-mana artifact back to your hand—ready to be recast and repeat the entire spectacle infinitely.
