Toph, the First Metalbender + Toph, Hardheaded Teacher + Rakdos Carnarium + Troubled Healer

Toph, the First Metalbender

Toph, Hardheaded Teacher

Rakdos Carnarium

Troubled Healer

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Rakdos Carnarium.
3. Resolve the artifact spell.
4. Activate Troubled Healer by sacrificing Rakdos Carnarium.
5. When Rakdos Carnarium dies, Toph, Hardheaded Teach triggers, returning Rakdos Carnarium from your graveyard to the battlefield tapped.
6. When Rakdos Carnarium 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 intricate loop transforms a humble zero-cost artifact into a land thanks to Toph, the First Metalbender, which brilliantly satisfies Rakdos Carnarium's bouncing requirement and Troubled Healer's sacrificial craving. Every time you recast your artifact, Toph, Hardheaded Teacher triggers its earthbend ability while fueling your hand with returned spells. When you sacrifice Rakdos Carnarium to Troubled Healer, its death triggers Toph, Hardheaded Teacher's safety net to bring it right back to the battlefield tapped, where its enter-the-battlefield trigger scoops your artifact-turned-land back up to repeat the cycle indefinitely.
