Yeah, the only match I've lost so far in singles was to Knuckles, and I might have won, had I Ice Beamed the crap out of his Cress instead of DPulsing it. I was hoping for a crit, but I should have frozen it instead. :P
Oh, dude, you're welcome to do a VGC match with me, any of the dudes from the Gym, or any of my VGC buds at any time, and you definitely already have all the pokes you could ever need!
