Toph, the First Metalbender + Toph, Hardheaded Teacher + Carrion Feeder + Rakdos Carnarium

Toph, the First Metalbender

Toph, Hardheaded Teacher

Carrion Feeder

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 Carrion Feeder 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 Carrion Feeder ability
8. Repeat.

This ingenious loop transforms your cheap artifacts into lands using Toph, the First Metalbender, setting up a recursive engine where Rakdos Carnarium constantly bounces and replays them. Toph, Hardheaded Teacher provides the vital safety net, ensuring that whenever your sacrificed land hits the graveyard, its earthbend trigger returns it safely to the battlefield. Meanwhile, Carrion Feeder acts as the executioner, converting each iteration into an ever-growing threat by consuming the animated lands to fuel an endless chain of sacrifices, enter-the-battlefield triggers, and storm count.
