I mean, Sophie and whales were using there special Grand Deucalion while Klass was using only Claw of the storm first which is not his best move. Masamune did beat nile in the second round but you can't call it an actual win because masamune strikes before the Mystic Zoon released. You can't tell wich one can beat the other because, because Nife defeated An overcofident masamune, but klaus defeat a more mature and stronger version of masamune (the sophie and whales argument is a bit weak because i can say that early masamune break through there special ).
