Toph, the First Metalbender + Haru, Hidden Talent + Stonework Puma + Phantom Train

Toph, the First Metalbender

Haru, Hidden Talent

Stonework Puma

Phantom Train

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 Phantom Train 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 Phantom Train ability.
7. Repeat from step 3.

This ingenious loop turns your nontoken artifacts into lands thanks to Toph, the First Metalbender, allowing them to benefit directly from land-based synergies. When Stonework Puma enters the battlefield as an Ally, it triggers Haru, Hidden Talent, which earthbends the Puma into a creature-land hybrid that can be fed into Phantom Train's sacrifice ability. Because Phantom Train turns itself into a creature while putting a +1/+1 counter on it, you can repeatedly sacrifice the Puma to the Train, triggering Haru to return the fallen Puma straight back to the battlefield.
