Toph, the First Metalbender + Toph, Hardheaded Teacher + Simic Growth Chamber + Bloodflow Connoisseur

Toph, the First Metalbender

Toph, Hardheaded Teacher

Simic Growth Chamber

Bloodflow Connoisseur

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Simic Growth Chamber.
3. Resolve the artifact spell.
4. Activate Bloodflow Connoisseur by sacrificing Simic Growth Chamber.
5. When Simic Growth Chamber dies, Toph, Hardheaded Teach triggers, returning Simic Growth Chamber from your graveyard to the battlefield tapped.
6. When Simic Growth Chamber 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 fascinating loop turns your free artifacts into an endless engine of sacrifice and recursion, entirely orchestrated by the battlefield rules established by Toph, the First Metalbender. Because Toph reclassifies your nontoken artifacts as lands, playing a zero-mana artifact lets Toph, Hardheaded Teacher turn Simic Growth Chamber into an active participant in your earthbending triggers. You then feed that animated bouncing land directly to Bloodflow Connoisseur, whose sacrifice ability triggers Simic Growth Chamber's safety net to bring itself right back via Toph's earthbend clause. Finally, the returning Simic Growth Chamber's own entry trigger bounces the original zero-mana artifact back to your hand, resetting the entire cycle for infinite triggers and boundless growth.
