Ebondeath, Dracolich + Rooftop Storm + Carrion Feeder

Ebondeath, Dracolich

Rooftop Storm

Carrion Feeder

How it works

1. Cast Ebondeath from your graveyard by paying 0.
2. Activate Carrion Feeder by sacrificing Ebondeath, putting a +1/+1 counter on Carrion Feeder.
3. Repeat.

This loop turns the graveyard into an endless armory, fueled entirely by the free casting made possible by Rooftop Storm. Because Ebondeath, Dracolich can be cast directly from your graveyard the moment any other creature dies, sacrificing it to Carrion Feeder immediately satisfies its own revival condition. You can loop this process infinitely, feeding Carrion Feeder as many times as you like to grow it into a colossal threat while generating an endless stream of triggers.
