Toph, the First Metalbender + Haru, Hidden Talent + Stonework Puma + Thaumatog

Toph, the First Metalbender

Haru, Hidden Talent

Stonework Puma

Thaumatog

How it works

1. Cast Stonework Puma by paying 3.
2. When Stonework Puma enters, Haru triggers, targeting Stonework Puma as it is a land due to Toph.
3. Activate Thaumatog by sacrificing Stonework Puma.
4. When Stonework Puma dies, Haru triggers, returning Stonework Puma from your graveyard to the battlefield tapped.
5. When Stonework Puma enters, Haru triggers, targeting Stonework Puma as it is a land due to Toph.
6. Resolve the Thaumatog ability.
7. Repeat from step 3.

This clever loop hinges entirely on Toph, the First Metalbender turning your artifacts into lands, transforming the unassuming Stonework Puma into a valid target for earthbending. Once Haru, Hidden Talent is present to earthbend the Puma into an animated land upon its entry, Thaumatog provides the necessary outlet to sacrifice it. Because the earthbend mechanic ensures the land returns to the battlefield tapped when it dies or is exiled, the Puma cycles smoothly back into play to trigger Haru all over again.
