Toph, the First Metalbender + Toph, Hardheaded Teacher + Gruul Turf + Trenching Steed

Toph, the First Metalbender

Toph, Hardheaded Teacher

Gruul Turf

Trenching Steed

How it works

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

This brilliant loop turns the rules of the battlefield inside out by leveraging Toph, the First Metalbender to permanently turn your nontoken artifacts into lands, allowing them to dodge traditional destruction and interact seamlessly with land-based mechanics. With that foundation set, you cast a zero-mana artifact to trigger Toph, Hardheaded Teacher, which earthbends your Gruul Turf into a creature; you then sacrifice that very same Gruul Turf to Trenching Steed. Because Gruul Turf was technically a land due to Toph, the First Metalbender, its death triggers Toph, Hardheaded Teacher's return effect to bring it right back to the battlefield tapped, where its own entry trigger forces it to bounce your original artifact back to your hand so you can cast it all over again.
