Retreat to Emeria + Haru, Hidden Talent + Yahenni, Undying Partisan

Retreat to Emeria

Haru, Hidden Talent

Yahenni, Undying Partisan

How it works

1. Play a land.
2. When the land enters, Retreat to Emeria triggers, creating a 1/1 Kor Ally creature token.
3. When the Kor Ally enters, Haru triggers, earthbending the land that entered.
4. Activate Yahenni by sacrificing the earthbended land.
5. Haru triggers, returning the land from your graveyard to the battlefield tapped.
6. When the land enters, Retreat to Emeria triggers, creating a 1/1 Kor Ally creature token.
7. When the Kor Ally enters, Haru triggers, earthbending the land that entered.
8. Resolve the Yahenni ability from step 4.
9. Repeat from step 4.

This clever loop sets up a self-sustaining cycle of landfall and sacrifice using your land drops and allies. Every time you drop a land, Retreat to Emeria triggers to spawn a Kor Ally token, which in turn prompts Haru, Hidden Talent to animate that same land into an earthbended creature. From there, you can use Yahenni, Undying Partisan to sacrifice the land-creature—feeding Yahenni's hunger—which triggers Haru's return-to-battlefield clause to seamlessly bring the land right back tapped, ready to fuel the cycle all over again.
