Rise of the Dark Realms + Phyrexian Altar + Shipwreck Dowser

Rise of the Dark Realms

Phyrexian Altar

Shipwreck Dowser

How it works

1. Activate Phyrexian Altar twice by sacrificing Shipwreck Dowser, adding .
2. Repeat step 1 for each other nontoken creature you control.
3. Cast Rise of the Dark Realms by paying 7, returning all creature cards from all graveyards to the battlefield under your control.
4. When Shipwreck Dowser enters the battlefield, it triggers, returning Rise of the Dark Realms to your hand from your graveyard.
5. Repeat.

This loop transforms a graveyard full of fallen foes into an endless engine of rebirth, fueled by the terrifying mass reanimation of Rise of the Dark Realms. As your entire army floods the battlefield, Shipwreck Dowser swoops in on entry to effortlessly loop that very sorcery right back to your hand. Meanwhile, Phyrexian Altar acts as the ultimate sacrificial altar, turning those fresh bodies into a steady stream of colored mana to recast the spell over and over again.
