Yedora, Grave Gardener + Living Plane + Altar of Dementia

Yedora, Grave Gardener

Living Plane

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing another nontoken creature.
2. When the creature dies, Yedora triggers, returning the creature from your graveyard to the battlefield face down as a Forest land and as a 1/1 creature due to Living Plane.
3. Resolve the Altar of Dementia ability, causing target player to mill cards equal to the creature's power.
4. Repeat.

This ingenious loop transforms your entire battlefield into a self-sustaining engine of endless mill. With Living Plane turning every land—including your creatures—into 1/1 creatures, sacrificing any nontoken creature to Altar of Dementia sends it to the graveyard while milling your opponent. Yedora, Grave Gardener immediately catches that death trigger, slipping the creature right back onto the battlefield face down as a new Forest land. Because of Living Plane's continuous effect, that freshly returned Forest is *also* still a 1/1 creature ready to be fed back into Altar of Dementia, letting you repeat the process indefinitely for an infinite mill victory.
