Toph, the First Metalbender + Toph, Hardheaded Teacher + Overgrown Estate + Dimir Aqueduct

Toph, the First Metalbender

Toph, Hardheaded Teacher

Overgrown Estate

Dimir Aqueduct

How it works

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

This crafty loop transforms a free artifact into an infinite engine by leveraging Toph, the First Metalbender, whose static ability turns your nontoken artifacts into lands. With that foundation set, casting your free artifact triggers Toph, Hardheaded Teacher to animate Dimir Aqueduct, setting up Overgrown Estate as a sacrifice outlet that fuels both your life total and the loop. When Dimir Aqueduct hits the graveyard, Toph's earthbend clause returns it to the battlefield tapped, where its own bounce trigger targets the artifact. Because Toph, the First Metalbender treats that artifact as a land, the bounce successfully returns it to your hand to be recast, generating boundless landfall, life, and death triggers.
