Toph, the First Metalbender + Toph, Hardheaded Teacher + Umbral Collar Zealot + Orzhov Basilica

Toph, the First Metalbender

Toph, Hardheaded Teacher

Umbral Collar Zealot

Orzhov Basilica

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Orzhov Basilica.
3. Resolve the artifact spell.
4. Activate Umbral Collar Zealot by sacrificing Orzhov Basilica.
5. When Orzhov Basilica dies, Toph, Hardheaded Teach triggers, returning Orzhov Basilica from your graveyard to the battlefield tapped.
6. When Orzhov Basilica 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 Umbral Collar Zealot ability
8. Repeat.

This clever loop turns zero-mana artifacts into a perpetual engine by weaving together type-changing magic and sacrifice synergies. Thanks to Toph, the First Metalbender, your nontoken artifacts are lands, meaning Orzhov Basilica's entry trigger can bounce them right back to your hand. Meanwhile, Toph, Hardheaded Teacher triggers on every spell you cast to earthbend your lands into animated creatures, setting them up to be sacrificed to Umbral Collar Zealot for surveil value. When that animated Orzhov Basilica hits the graveyard, Toph, Hardheaded Teacher's own trigger safely returns it to the battlefield, restarting the cycle and fueling endless storm count, landfall, and death triggers.
