Morophon, the Boundless + Fist of Suns + Ebondeath, Dracolich + Altar of Dementia

Morophon, the Boundless

Fist of Suns

Ebondeath, Dracolich

Altar of Dementia

How it works

1. Cast Ebondeath from your graveyard by paying 0.
2. Activate Altar of Dementia by sacrificing Ebondeath, causing target player to mill cards equal to Ebondeath's power.
3. Repeat.

This clever loop turns the graveyard into an endless engine of ruin by combining Morophon, the Boundless with Fist of Suns. Because Morophon makes chosen-type spells cost five colored mana less, and Fist of Suns allows you to pay {W}{U}{B}{R}{G} for any spell, your chosen-type spells—including dragons like Ebondeath, Dracolich—effectively become completely free to cast. Once Ebondeath enters the battlefield, you simply feed it to Altar of Dementia, milling your opponent while fulfilling Ebondeath's own condition that another creature died so you can flash it right back out of the graveyard and do it all over again.
