Yedora, Grave Gardener + Proteus Machine + Starved Rusalka

Yedora, Grave Gardener

Proteus Machine

Starved Rusalka

How it works

1. Activate Starved Rusalka by paying and sacrificing Proteus Machine.
2. When Proteus Machine dies, Yedora triggers, returning Proteus Machine to the battlefield face down as a Forest land.
3. Resolve the Starved Rusalka ability, causing you to gain 1 life.
4. Activate Proteus Machine by tapping it, adding .
5. Activate Proteus Machine's morph ability by paying 0, turning it face up.
6. Repeat.

This clever botanical loop transforms Proteus Machine into a self-sustaining mana source and sacrifice engine. With Yedora, Grave Gardener turning any dying nontoken creature into a fresh Forest land on the battlefield face down, your sacrificed automaton immediately returns ready to tap for green mana. You can then pay {0} to utilize Proteus Machine's morph ability to turn it face up, clearing the way to sacrifice it once more to Starved Rusalka for a steady stream of life gain and endless triggers.
