I don't believe that's true. From the top of my head, theres still berserk that he hasnt used yet. plus all the lich ring skills
If he had moves like thunderblast , blink and full counter , which he only used once in the entire tournament .... How many more hidden moves does he have? How much more strength has he hidden?
And you don't know how true this is until it is too late to realize. I have heard about a ranger from LA who didn't know sh*t about tracking skills and led his team to their doom.
