Rise of the Dark Realms + Phyrexian Altar + Greenwarden of Murasa

Rise of the Dark Realms

Phyrexian Altar

Greenwarden of Murasa

How it works

1. Activate Phyrexian Altar twice by sacrificing Greenwarden of Murasa, 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 Greenwarden of Murasa enters the battlefield, it triggers, returning Rise of the Dark Realms to your hand from your graveyard.
5. Repeat.

By casting Rise of the Dark Realms, you flood the battlefield with every creature card waiting in all graveyards, setting the stage for Greenwarden of Murasa to immediately enter and trigger its ability to pull that very same spell right back to your hand. Meanwhile, Phyrexian Altar acts as the necessary engine to convert your newly amassed army into the mana required to cast Rise of the Dark Realms over and over again. As Greenwarden of Murasa is repeatedly sacrificed to the Altar, its second ability can even be used to recycle other valuable cards from your graveyard, creating an unstoppable loop of resurrection and resource generation.
