Toph, the First Metalbender + Toph, Hardheaded Teacher + Ashnod's Altar + Azorius Chancery

Toph, the First Metalbender

Toph, Hardheaded Teacher

Ashnod's Altar

Azorius Chancery

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Azorius Chancery.
3. Resolve the artifact spell.
4. Activate Ashnod's Altar by sacrificing Azorius Chancery.
5. When Azorius Chancery dies, Toph, Hardheaded Teach triggers, returning Azorius Chancery from your graveyard to the battlefield tapped.
6. When Azorius Chancery 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. Repeat.

This clever engine turns free artifacts into an infinite resource generator by weaving land animation with a classic sacrifice loop. Toph, the First Metalbender does the heavy lifting of turning your nontoken artifacts into lands, which allows Azorius Chancery to bounce them back to your hand when it enters the battlefield. Meanwhile, Ashnod's Altar provides the graveyard fodder by sacrificing your animated land, and Toph, Hardheaded Teacher ensures that dying land immediately returns to the battlefield tapped to restart the cycle while generating a storm of triggers and infinite colorless mana.
