Morophon, the Boundless + Jodah, Archmage Eternal + Ebondeath, Dracolich + Phyrexian Altar

Morophon, the Boundless

Jodah, Archmage Eternal

Ebondeath, Dracolich

Phyrexian Altar

How it works

1. Cast Ebondeath from your graveyard by paying 0.
2. Activate Phyrexian Altar by sacrificing Ebondeath, adding one mana of any color.
3. Repeat.

This brilliant engine hinges on Jodah, Archmage Eternal, whose ability lets you cast any spell by paying {W}{U}{B}{R}{G} rather than its printed mana cost. With Morophon, the Boundless naming the Dragon creature type, that alternative cost is entirely wiped out, allowing you to cast your Dragons for free. This opens the door for Ebondeath, Dracolich to leap from your graveyard repeatedly, utilizing its conditional recursion enabled by its own death. Each time Ebondeath returns and meets its demise in Phyrexian Altar, the altar converts the sacrifice into a colored mana, fueling an endless loop of free casts and unlimited resources.
