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

Toph, the First Metalbender

Haru, Hidden Talent

Stonework Puma

Sarcatog

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 Sarcatog 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 Sarcatog ability.
7. Repeat from step 3.

This clever loop relies on Toph, the First Metalbender turning Stonework Puma—an Ally—into a land the moment it enters the battlefield alongside your other nontoken artifacts. Because of this land-type addition, Haru, Hidden Talent treats the entering Stonework Puma as a valid target for its earthbend trigger, allowing you to continually animate and loop it. You then feed Stonework Puma directly to Sarcatog by sacrificing it as an artifact, which triggers its return from the graveyard to the battlefield tapped and restarts the whole cycle.
