Yedora, Grave Gardener + Phyrexian Altar + Wall of Deceit

Yedora, Grave Gardener

Phyrexian Altar

Wall of Deceit

How it works

1. Activate Phyrexian Altar by sacrificing Wall of Deceit, adding .
2. When Wall of Deceit dies, Yedora triggers, returning Wall of Deceit from your graveyard to the battlefield face down as a Forest land.
3. Activate Wall of Deceit by tapping it, adding .
4. Activate Wall of Deceit's morph ability by paying , turning it face up.
5. Repeat.

This loop turns your graveyard into a self-sustaining engine by utilizing Yedora, Grave Gardener to constantly recycle your fallen creatures into lands. When you sacrifice Wall of Deceit to Phyrexian Altar, Yedora's static ability immediately steps in to return it to the battlefield face down as a Forest land, which can be tapped for green mana. To reset the loop, you use the mana provided by Phyrexian Altar to pay for Wall of Deceit's own morph ability, turning it face up once again so it's ready to be sacrificed anew.
