Great battle. I've become unused to playing against opponents able to predict, it makes the game so much more fun. The hax in the battle doesn't really bother me either, I had fun which is what matters, and I feel priveliged to have battled you.
Scarf Slaking has worked wonders the few battles I've used him. His build is,
Pursuit
Double-Edge
Encore
EQ (he cannot learn Superpower)
I run a build hitting an exact speed number so he has incredible bulk with the leftover EVs.
I certainly hope to battle you in the future, great game.
