Zapdos entered, Drizzle activated, used Hurricane, but it missed. Isn't it supposed to always hit in rain?
Also, I'm not sure that Sand Rush is working properly... Moltres, Articuno, Tyranitar, and Flygon all entered. So weather changed from nothing to sun to hail to sand. But the turn order was Moltres, Articuno, Flygon, Tyranitar. I would think that Flygon would go first, with a doubled speed. Flygon is about 10 levels lower, but I wouldn't think there'd be that much of a gap.
Also, I've been waiting a while for the final battle with Miror B. Longer than I normally have to wait for the radar to go off. Is it supposed to be like that?
Another weird thing: Registeel used Curse 2 times and so is going first when Trick Room is on. But then Trick Room expires, and it still goes before Dusclops (same level). Dusclops is super slow, but its Speed stat is not less than half of Registeel's.
