HBox said it best "There may come a day when the Kazuya players stop making mistakes, and he needs to be ban. But for now, I enjoy watching him play..... Hate playing against him!! Like !! OMG I feel bad for everyone stuck in the ring with that thing!! ... but for now, it's entertaining at least.
I'm quite sure this is a good matchup for Corrin actually. Riddles is just quite good otherwise. When I see Shadic up against Riddles I know that Riddles is losing. Unless Riddles gets lucky Shadic's Corrin destroys Kazuya.
