Morophon, the Boundless + Jodah, Archmage Eternal + Ebondeath, Dracolich + Yahenni, Undying Partisan

Morophon, the Boundless

Jodah, Archmage Eternal

Ebondeath, Dracolich

Yahenni, Undying Partisan

How it works

1. Cast Ebondeath from your graveyard by paying 0.
2. Activate Yahenni by sacrificing Ebondeath, giving it indestructible until end of turn.
3. Repeat.

This fascinating loop turns Jodah, Archmage Eternal's alternative casting cost into a completely free engine by leveraging Morophon, the Boundless, which you name Dragons for to slice the exact {W}{U}{B}{R}{G} colored requirement right off the top. With that prohibitive cost entirely eliminated, Ebondeath, Dracolich can be repeatedly cast straight from your graveyard the moment any creature dies. To fuel that requirement on demand, Yahenni, Undying Partisan stands ready to repeatedly sacrifice Ebondeath, utilizing its own sacrifice ability to generate endless death, entry, and exit triggers while driving your storm count through the roof.
