Toph, the First Metalbender + Toph, Hardheaded Teacher + Guildless Commons + Troubled Healer

Toph, the First Metalbender

Toph, Hardheaded Teacher

Guildless Commons

Troubled Healer

How it works

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

This brilliant loop transforms your zero-mana artifacts into a perpetual engine by turning them into lands using Toph, the First Metalbender's static ability. With that foundation set, you can cast your artifact for free, letting Guildless Commons bounce it back to your hand when the land enters the battlefield. Then, you sacrifice that very same Guildless Commons to Troubled Healer, triggering Toph, Hardheaded Teacher to safely return the land to the battlefield. Meanwhile, every spell you cast along the way is supercharged by Toph, Hardheaded Teacher's triggered ability to continually earthbend your lands into creature threats.
