Toph, the First Metalbender + Toph, Hardheaded Teacher + Guildless Commons + Bloodflow Connoisseur

Toph, the First Metalbender

Toph, Hardheaded Teacher

Guildless Commons

Bloodflow Connoisseur

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 Bloodflow Connoisseur 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 Bloodflow Connoisseur ability
8. Repeat.

This ingenious loop uses Toph, the First Metalbender to turn cheap artifacts into lands, transforming Guildless Commons into a recurring bounce-engine whenever it hits the battlefield. As Guildless Commons repeatedly returns your free artifact to your hand, you can recast it to trigger Toph, Hardheaded Teacher and earthbend your lands into creatures. This sets up Bloodflow Connoisseur to cheerfully sacrifice those animated lands, feeding its own growth while triggering Toph, Hardheaded Teacher's safety net to bring the land right back to the battlefield tapped.
