Toph, the First Metalbender + Toph, Hardheaded Teacher + Boros Garrison + Troubled Healer

Toph, the First Metalbender

Toph, Hardheaded Teacher

Boros Garrison

Troubled Healer

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 Troubled Healer 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 Troubled Healer ability
8. Repeat.

This mesmerizing loop turns a humble cost-free artifact into an infinite engine by leveraging the continuous type-shifting power of Toph, the First Metalbender, which permanently transforms your nontoken artifacts into lands. With that foundation set, casting your artifact triggers Toph, Hardheaded Teacher to awaken Boros Garrison into a creature, allowing Troubled Healer to sacrifice it for a damage prevention shield. Because Boros Garrison is actually a land, its death triggers the return clause built into Toph's earthbend effect, sending the Garrison straight back to the battlefield tapped. When Boros Garrison re-enters, its own triggered ability forces you to bounce a land to your hand—and thanks to Toph, the First Metalbender, you can conveniently target the artifact you just cast, looping it right back to your hand to start the cycle anew for endless storm count and triggers!
