Toph, the First Metalbender + Toph, Hardheaded Teacher + Izzet Boilerworks + Need for Speed

Toph, the First Metalbender

Toph, Hardheaded Teacher

Izzet Boilerworks

Need for Speed

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 Need for Speed 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 Need for Speed ability
8. Repeat.

This clever loop turns the self-bouncing nature of Izzet Boilerworks into an engine for endless triggers by exploiting type manipulation and sacrifice. Toph, the First Metalbender is the linchpin that transforms your nontoken artifacts into lands, allowing Izzet Boilerworks's entry trigger to bounce that zero-mana artifact right back to your hand. Meanwhile, Need for Speed provides the necessary outlet to sacrifice your animated, earthbent Izzet Boilerworks for a rush of haste. When it dies, Toph, Hardheaded Teacher steps in to return the land straight to the battlefield tapped, instantly restarting the cycle and triggering further earthbending from Toph, Hardheaded Teacher with each spell cast.
