When Angel of Glory's Rise enters the battlefield, it triggers.
Holding priority, activate Phyrexian Altar by sacrificing Angel of Glory's Rise, adding one mana of any color.
Resolve the Angel of Glory's Rise trigger, exiling all Zombies, then returning all creature cards from your graveyard to the battlefield.
Repeat from step 2.
This clever loop transforms a graveyard full of creatures into an endless cascade of life and mana, perfectly orchestrated by Rukarumel, Biologist. Because Rukarumel makes all nontoken creatures and creature cards you own into Slivers in addition to their other types, Angel of Glory's Rise enters the battlefield not just as a Human, but as a Sliver too—meaning it can immediately be sacrificed to Phyrexian Altar for any color of mana. That very sacrifice sends the Angel straight to the graveyard, ready to be immediately reanimated by its own enter-the-battlefield trigger which targets all Humans.
