Toph, the First Metalbender + Toph, Hardheaded Teacher + Altar of Dementia + Rakdos Carnarium

Toph, the First Metalbender

Toph, Hardheaded Teacher

Altar of Dementia

Rakdos Carnarium

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 Altar of Dementia 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 Altar of Dementia ability
8. Repeat.

This ingenious loop relies on Toph, the First Metalbender turning your cheap non-token artifacts into lands, transforming ordinary items into reusable ammunition. While you cast and replay your artifacts, Toph, Hardheaded Teacher continually earthbends your lands and lets you recur cards, while Rakdos Carnarium's self-bounce trigger effortlessly picks the artifact back up when it enters the battlefield. Finally, Altar of Dementia capitalizes on the earthbent land's growing power each cycle, turning your churning artifacts into an infinite sacrifice engine that mills your opponents out entirely.
