Yedora, Grave Gardener + Ambush Commander + Troubled Healer

Yedora, Grave Gardener

Ambush Commander

Troubled Healer

How it works

1. Activate Troubled Healer by sacrificing a nontoken Forest, which is a creature due to Ambush Commander.
2. When the Forest dies, Yedora triggers, returning the Forest from your graveyard to the battlefield face down as a Forest land.
3. Resolve the Troubled Healer ability.
4. Repeat.

This clever loop transforms your lands into an endlessly recycling resource by leveraging Ambush Commander's static ability to turn every Forest you control into a 1/1 green Elf creature. Once your lands are breathing, you can feed one to Troubled Healer's activated ability by sacrificing it as a land (which is also a creature), instantly triggering Yedora, Grave Gardener to bring that very same Forest right back to the battlefield face down as a fresh Forest land. Because the sacrificed card returns to play anew, you can continually cycle it through the graveyard to rack up endless death, sacrifice, and landfall triggers for whatever payoff your heart desires.
