Toph, the First Metalbender + Toph, Hardheaded Teacher + Carrion Feeder + Izzet Boilerworks

Toph, the First Metalbender

Toph, Hardheaded Teacher

Carrion Feeder

Izzet Boilerworks

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Izzet Boilerworks.
3. Resolve the artifact spell.
4. Activate Carrion Feeder by sacrificing Izzet Boilerworks.
5. When Izzet Boilerworks dies, Toph, Hardheaded Teach triggers, returning Izzet Boilerworks from your graveyard to the battlefield tapped.
6. When Izzet Boilerworks 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 intricate loop transforms a humble zero-mana artifact into a recurring engine of destruction by turning it into a land through Toph, the First Metalbender's static ability. Once it is a land, Izzet Boilerworks can bounce it back to your hand every time the bounceland enters the battlefield, allowing you to replay it endlessly. Meanwhile, Carrion Feeder acts as the sacrificial outlet that sends Izzet Boilerworks to the graveyard, triggering Toph, Hardheaded Teacher to instantly cheat the land right back onto the battlefield.
