Zimone, Mystery Unraveler

Yedora, Grave Gardener

Yavimaya Elder

Biomancer's Familiar

How it works

1. Activate Yavimaya Elder by paying 1 and sacrificing it.
2. When Yavimaya Elder dies, it and Yedora trigger.
3. Resolve the Yavimaya Elder trigger, allowing you to search your library for up to two basic land cards and put them into your hand.
4. Resolve the Yedora trigger, returning Yavimaya Elder from your graveyard to the battlefield face-down as a Forest land.
5. When Yavimaya Elder enters, Zimone triggers.
6. Holding priority, activate Yavimaya Elder by tapping it, adding .
7. Resolve the Zimone trigger, turning Yavimaya Elder face-up.
8. Resolve the Yavimaya Elder ability from step 1, causing you to draw a card.
9. Repeat.

This intricate engine centers on the constant death and rebirth of Yavimaya Elder, whose sacrifice ability is conveniently discounted by Biomancer's Familiar so you can crack it over and over. When the Elder hits the graveyard, Yedora, Grave Gardener swoops in to resurrect it directly to the battlefield as a face-down Forest land. That very land drop immediately triggers Zimone, Mystery Unraveler, whose landfall ability allows you to flip the Elder back face-up just in time to resolve its sacrificed draw ability and feed the loop infinitely.
