Rise of the Dark Realms + Phyrexian Altar + Timeless Witness

Rise of the Dark Realms

Phyrexian Altar

Timeless Witness

How it works

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

This loop transforms a massive graveyard into a self-sustaining engine by letting Rise of the Dark Realms pull every creature back into play at once. As the horde arrives, Timeless Witness triggers to pull that very same sorcery right back to your hand, securing your ammunition for the next turn. Meanwhile, Phyrexian Altar acts as the sacrificial altar that converts your entire disposable army into the precise mana needed to cast Rise of the Dark Realms over and over again.
