Toph, the First Metalbender + Toph, Hardheaded Teacher + Woe Strider + Gruul Turf

Toph, the First Metalbender

Toph, Hardheaded Teacher

Woe Strider

Gruul Turf

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 Woe Strider 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 Woe Strider ability
8. Repeat.

This clever loop turns the mechanical synergy of the earthbender permanents into a self-sustaining engine by transforming artifacts into lands. With Toph, the First Metalbender turning your nontoken artifacts into lands, casting a zero-mana artifact triggers Toph, Hardheaded Teacher to animate Gruul Turf into a creature. You can then sacrifice that animated land to Woe Strider's sacrifice ability, triggering the Teacher's delayed safety net to return Gruul Turf straight to the battlefield tapped. When Gruul Turf enters, its own bounce trigger targets the original artifact—which is currently a land—returning it to your hand so you can cast it all over again for infinite sacrifice and landfall triggers.
