Fanfare: Replace your deck with an Apocalypse Deck.
The would-be usurper of Heaven, cast into the pits of Hell, has risen again in a cloak of flame. Soon this underworld king shall spark an apocalypse that paints all mortals and gods in blood.

Fanfare: Replace your deck with a Cocytus Deck.
The Heavens fall to Earth. Earth plunges into Hell. Cocytus swallows all, robbing Creation of breath and entombing it in ice. Conqueror. Serpent. Father of Lies. Being with faces innumerable—none of them true. The only certainty is this: He is the world's adversary.
Evolved
–
Part your lips to speak: Ice will take your throat, twine through your entrails. Be silent: Ice will seal your lips eternally. Blades shall rust away. Knowledge burn to cinders. Life shall be Cocytus's shivering prisoner. The only option is this: To cast this world aside.
Until the start of your next turn, add 10 to the original cost of spells in your opponent's hand. (Only affects cards in hand at the time this effect is activated.)

Ethereal soul or corporeal flesh, a frozen fate awaits all beings caught in gelid gaze.
