Morophon, the Boundless + Fist of Suns + Ebondeath, Dracolich + Goblin Bombardment

Morophon, the Boundless

Fist of Suns

Ebondeath, Dracolich

Goblin Bombardment

How it works

1. Cast Ebondeath from your graveyard by paying 0.
2. Activate Goblin Bombardment by sacrificing Ebondeath, dealing 1 damage to any target.
3. Repeat.

By combining Morophon, the Boundless with Fist of Suns, a fascinating mana-reduction loop is born: Fist of Suns allows you to pay a generic five-color mana cost for any spell, and Morophon, the Boundless reduces that exact five-color cost by {W}{U}{B}{R}{G} when you name Dragon as the chosen type, making your Dragon spells completely free to cast. With Ebondeath, Dracolich enabled to repeatedly crawl out of your graveyard whenever a creature dies—a condition easily met by sacrificing it—you can cast it for zero mana over and over again. Finally, Goblin Bombardment provides the sacrificial outlet needed to turn each iteration of this free recursion into infinite damage and infinite death triggers.
