I understand what Gliscor is used for, and I'm not a pro Ubers player, but I did hit 1 on Showdown and Beta Ubers a while back, so I think I at least know a little bit what I am talking about.
If you honestly have no check to SubToxic Scor you probably deserve to lose anyways. That strat doesn't work as well as it does in OU, Gliscor just cannot keep up with how offensive Ubers is.
Jesus, I am not saying Kyu-B>Zekrom, I am saying it fulfills a niche, which is a harder hitting Outrage and a base 95 Speed.
