I used to really like stall, but now I'm not so sure with B-Kyurem blasting SkarmBliss and AmoongBro to pieces and Keldeo smashing through most stall teams lacking Jellicent. (but it has HP ghost/electric for that). I have respect for stall because you can get a 1700+ rating due to impatient people. People, however, won't hesitate to cuss you out for using stall. It happened to me several times. I think it might have been possible in BW, but BW2 is just too much. Maybe one of you can prove me wrong? Possibly raise a point I hadn't thought of.
