lol this thread has been pretty amusing, though I can't tell who has been serious and who is legitimately pissed O_o.
Anyway, I used hail for a chunk of this round (or whatever the fuck is going on with uu at the moment), and I suggest testing Taunt over Thunder Wave on Froslass. Thunder Wave is annoying as shit, yes, and is probably better for the ladder (as the majority of the players on the ladder aren't very good -_-), but Taunt imo is the more competitive move, as it leaves Blastoise, the most popular spinner at the moment, completely fucked to do anything. It's also just generally very useful against opposing stall teams.
Also, I haven't really found max speed on Froslass to be necessary, try out 176 spd with a timid nature, you outspeed +natured 100's, and that leaves you with some extra evs to make Froslass quite a bit bulkier, which I have found extremely useful to get that extra layer of spikes, etc.
I am going to have to agree with Whitqueen that Suicune > Milotic for this team, Suicune hits 361 def at max, while Milotic hits 282 def at max. That is a HUGE difference, that imo, outweighs having a reliable form of recovery in Milotic, because Whitequeen needs Suicune to take all kinds of hits. Using Milotic would make him even weaker to powerful physical threats, such as CB Escavalier, Heracross, etc. Also, having a dedicated sleep absorber is always nice.
If you do decide to use Taunt on Froslass, I think Psychic would be a great choice on Mew. I really don't like the idea of using pokemon with no attack moves, as it makes it easy set up bait. If I had to choose any pokemon with no attacking moves, Mew would probably be up there just because there isn't a whole lot that can set up on it, but I still think Psychic would be very useful on him to hit those fighting types that can annoy your team.
Overall though, nice team. I never thought to use Cryogonal on my hail team, that's a nice touch. I wasn't fortunate enough to play this team (with you using it), though I remember playing you a number of times with you using that team with weaville, zapdos, and other shit I can't remember, and those were always close. Congrats on #1 and #2 on the ladder
