I'm currently playtesting a team for BW2 subway. I call it Team Yawn, that's how slow and stally it is! It's pretty much my old Ferrothorn (slightly different moveset), my old Chansey and ntrscn's idea of Gliscor, except my current one has a bit different EVs. I'm only at 57 wins so far, but I've noticed that so far there were no "close" battles. Not a single one. I'm always in control from start to finish. One time a silly Dragonite tried to freeze hax his way through my ferro and chansey, but ran out of PP lol.
I'll try reaching at least 100 wins or so, and continue this in subway. With a "proper" Gliscor this time, hopefully.
