Right, since we're near the end of the suspect test, I'm going to share my thoughts about Victini. During my laddering to reach requirements, I ran a stall team, consisting of what I consider 2 checks to Victini (defensive Arcanine, and Blastoise). Now, I did not chose to use these Pokemon because they are the best Victini checks, I used them because they supported my team. I think it's safe to say, I didn't have much much trouble when I faced Victini. I dunno if it's because of the lack of good players using it, but I was far more concerned when I faced Raikou or Togekiss (I wouldn't consider these Pokemon broken either, but that's beside the point). Now this is only my view from a defensive stand point, but I really don't think Victini troubles offensive teams enough to be banned either. After it's KOed something with Victini, it's easily revenge killed and huge Pursuit bait. Victini also requires a lot of prediction to use, as predicting wrong with Victini loses you a ton of momentum, and the fact that it's SR weak means it will get worn down pretty easily. Yes the Luretini can beat most of it's counters, but once the surprise factor has gone, it's much less effective than the standard banded set, and requires perfect timing to be effective.
All in all, I just don't think Victini is overwhelming enough to be banned to BL. It's a great Pokemon, sure, but it has solid checks, and has exploitable weaknesses. Victini should stay UU.
