This clever loop hinges on turning a self-recurring dragon into pure, engine-driving momentum. With Jodah, Archmage Eternal on the board, we are granted the option to pay the five-color mana cost of *WUBRG* to cast spells—which is where Morophon, the Boundless steps in as the ultimate enabler. By naming Dragon as Morophon's chosen type, its static cost-reduction completely negates Jodah's alternative cost, allowing you to cast Ebondeath, Dracolich from the graveyard for free. Once Ebondeath enters the battlefield, Carrion Feeder is right there waiting to greedily consume it as a sacrifice; since Ebondeath's own death satisfies the condition to recast it from the graveyard, you can instantly loop the dragon back out of the bin for zero mana.
