Toph, the First Metalbender + Toph, Hardheaded Teacher + Woe Strider + Dimir Aqueduct

Toph, the First Metalbender

Toph, Hardheaded Teacher

Woe Strider

Dimir Aqueduct

How it works

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

This ingenious loop turns your non-token artifacts into lands thanks to Toph, the First Metalbender, allowing them to double as fodder and targets for your engine. You cast a zero-mana artifact to trigger Toph, Hardheaded Teacher, which earthbends Dimir Aqueduct into an animate land so it can be sacrificed to Woe Strider. Because Dimir Aqueduct is a land, its entry trigger bounces the original zero-mana artifact back to your hand, letting you replay it indefinitely while Woe Strider lets you churn through your deck with infinite scries and sacrifice triggers.
