Toph, the First Metalbender + Toph, Hardheaded Teacher + Selesnya Sanctuary + Coastal Hornclaw

Toph, the First Metalbender

Toph, Hardheaded Teacher

Selesnya Sanctuary

Coastal Hornclaw

How it works

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

This ingenious loop turns your noncreature setup into a self-sustaining engine by weaving together land animation and bounce mechanics. Because Toph, the First Metalbender turns your nontoken artifacts into lands, they suddenly become valid targets to sacrifice to Coastal Hornclaw and can be returned to your hand by Selesnya Sanctuary's entry trigger. Meanwhile, Toph, Hardheaded Teacher capitalizes on the constant casting and dying by continuously earthbending, and its triggered ability can even rebuy instant or sorceries if you discard along the way.
