Yedora, Grave Gardener + Altar of Dementia + Kin-Tree Warden

Yedora, Grave Gardener

Altar of Dementia

Kin-Tree Warden

How it works

1. Activate Altar of Dementia by sacrificing Kin-Tree Warden.
2. When Kin-Tree Warden dies, Yedora triggers, returning Kin-Tree Warden from your graveyard to the battlefield face down as a Forest land.
3. Resolve the Altar of Dementia ability, causing target player to mill cards equal to Kin-Tree Warden's power.
4. Activate Kin-Tree Warden by tapping it, adding .
5. Activate Kin-Tree Warden's morph ability by paying , turning it face up.
6. Repeat.

This clever loop turns your graveyard into an endless milling engine by exploiting Yedora, Grave Gardener's ability to resurrect fallen nontoken creatures as face-down Forest lands. Altar of Dementia provides the sacrifice outlet that triggers this cycle while slowly milling away your opponent's library. Because the resurrected creature enters as a land, you can tap it for mana and use Kin-Tree Warden's own morph ability to flip it right back face up, ready to be sacrificed to Altar of Dementia all over again.
