Yuno is the man who believes that he will be the Wizard King someday. Hey you definitely can’t count him out, his skills are the real deal. I don’t see Muhyo being able to keep up for very long. While he does have a spellbook of his own, Muhyo’s not nearly as fast and his spells are more limited. Yuno is in the driver’s seat here. He can spam his wind blasts and even Muhyo’s strongest monsters will be doing down here. Yuno wins.
