Toph, the First Metalbender + Toph, Hardheaded Teacher + Shilgengar, Sire of Famine + Rakdos Carnarium

Toph, the First Metalbender

Toph, Hardheaded Teacher

Shilgengar, Sire of Famine

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 Shilgengar 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 Shilgengar ability
8. Repeat.

This brilliant loop turns your mana base and artifact support into a self-sustaining engine, anchored entirely by Toph, the First Metalbender transforming your non-token artifacts into lands. With that permanent type alteration in place, casting a zero-mana artifact triggers Toph, Hardheaded Teacher to earthbend your Rakdos Carnarium into an animate creature-land. You then feed that animated Rakdos Carnarium to Shilgengar, Sire of Famine to generate a Blood token, sending the land to the graveyard where Toph, Hardheaded Teacher's return trigger—wait, actually, the loop relies on Rakdos Carnarium's own bounce ability upon re-entering: when Rakdos Carnarium returns to the battlefield tapped, its entry trigger forces you to bounce a land, which is your castable artifact now treated as a land by Toph, the First Metalbender. Repeating this cycle endlessly leverages Shilgengar, Sire of Famine alongside the constant recycling of your artifact and land drops to flood the board with infinite triggers, sacrifice fodder, and Blood tokens.
