Toph, the First Metalbender + Toph, Hardheaded Teacher + Altar of Dementia + Boros Garrison

Toph, the First Metalbender

Toph, Hardheaded Teacher

Altar of Dementia

Boros Garrison

How it works

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

This loop hinges on a clever type-shifting interaction: **Toph, the First Metalbender** turns your nontoken artifacts into lands, transforming ordinary items into legal targets for your own land-based mechanics. Meanwhile, **Toph, Hardheaded Teacher** provides the ongoing earthbend triggers to turn those artifact-lands into creatures, making them ready fodder for **Altar of Dementia**. When you sacrifice that creature-land, its death triggers return it to the battlefield via its earthbend protection, which then triggers **Boros Garrison**'s bounce ability to pick up your artifact-land right back to your hand for zero cost.
