Toph, the First Metalbender + Toph, Hardheaded Teacher + Golgari Rot Farm + Bloodflow Connoisseur

Toph, the First Metalbender

Toph, Hardheaded Teacher

Golgari Rot Farm

Bloodflow Connoisseur

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Golgari Rot Farm.
3. Resolve the artifact spell.
4. Activate Bloodflow Connoisseur by sacrificing Golgari Rot Farm.
5. When Golgari Rot Farm dies, Toph, Hardheaded Teach triggers, returning Golgari Rot Farm from your graveyard to the battlefield tapped.
6. When Golgari Rot Farm 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 Bloodflow Connoisseur ability
8. Repeat.

This ingenious loop turns a simple zero-cost artifact into an engine of endless sacrifices, powered by Toph, the First Metalbender transforming your non-token artifacts into lands. With that foundation set, you can cast your artifact to trigger Toph, Hardheaded Teacher and earthbend Golgari Rot Farm into an animate land, which Bloodflow Connoisseur then eagerly devours for a sacrifice outlet. Thanks to the earthbend ability's built-in safety net, sacrificing the land triggers its return to the battlefield, where its native entry trigger lets you bounce your original artifact right back to your hand to start the cycle anew.
