I'm not sure where I saw it, but I definitely remember seeing a Delphox holding a Quick Claw. Maybe it means nothing. Then again, maybe it means Delphox is rather slow. Greninja is obviously fast. So that leaves Chesnaught to be the Bulky Mixed Attacker? But "Spiky Armor" or whatever it is certainly seems to be a great move.
It means nothing, we've seen Delphox's stats, it's a Charizard/Typhlosion-style relatively balanced speedy special sweeper.
