Grimoire/Deck

Grimoire's deck is a Magic World that focuses on the Plague Attribute. He focuses on gaining both his and his opponent's life with cards like Great Spell, Latent Infection, while building up Plague Spells into the soul of his item. Then when the number of Plague Spells in the soul of his item, he casts Ultimate Great Spell, World Pandemic with the help of his buddy, "Ashen Death Sorcery" Yersinieass Overkill to close the opponent's flag, preventing them from doing anything for the rest of the game. He then attacks them when they can't counterattack, sometimes casting Great Spell, Latent Infection again to make the opponent regain life so he can continue to attack the opponent.

"Gather forth, death plague demons that infect the world's potential. Proliferate your incurable curses! Luminize! World of Closed Potential!"
