Toph, the First Metalbender + Haru, Hidden Talent + Firdoch Core + Overgrown Estate

Toph, the First Metalbender

Haru, Hidden Talent

Firdoch Core

Overgrown Estate

How it works

1. Cast Firdoch Core by paying 3.
2. When Firdoch Core enters, Haru triggers, earthbending Firdoch Core, as it's a land due to Toph.
3. Activate Overgrown Estate by sacrificing Firdoch Core.
4. When Firdoch Core dies, Haru triggers, returning Firdoch Core from your graveyard to the battlefield.
5. When Firdoch Core enters, Haru triggers, earthbending Firdoch Core, as it's a land due to Toph.
6. Resolve the Overgrown Estate ability.
7. Repeat from step 3.

This clever loop hinges entirely on Toph, the First Metalbender transforming your nontoken artifacts into lands, which redefines how your permanents interact with the battlefield. Because Firdoch Core possesses changeling, it counts as an Ally that enters the battlefield to trigger Haru, Hidden Talent, while simultaneously functioning as a land that can be sacrificed to Overgrown Estate. When Firdoch Core goes to the graveyard, its death triggers Haru, Hidden Talent to bring it right back, setting up an endless cycle of sacrifice and rebirth that keeps your life total climbing ever higher.
