Is Wobbuffet uber or not?
No. I don't believe it's uber because I simply haven't had any trouble taking it down with ease. Sure, it allows one pokemon to set up, but a lack of recovery move, and all the different statuses + Toxic Spikes/Stealth Rock/Spikes mess it up in more ways than one. I personally like the fact that it punishes Choice users, because a lot of Choice users in themselves are pretty hard to stop otherwise if the player knows what they're doing.
Is Garchomp uber or not?
No. I have not ever had a huge problem with Garchomp. The only problem that I see with it is Sand Veil. However, you can't seriously expect every team with Garchomp to be carrying a Hippowdon/Tyranitar, because that just makes the team very predictable, which can lead to its own demise. I personally just use a fast statuser or Encorer to shut off its Swords Dancing, and then I destroy it. Of course, it requires much more prediction to beat than a lot of other OUs, but I feel that this differentiates the good players from the bad players if they can predict Garchomp's moves to take it out.
Are Latios and Latias uber or not? And if they aren't, should Soul Dew be banned or not?
Not really. I didn't participate in the Eon tourney, so I don't have much of an opinion on them, and of course Soul Dew's going to have to be banned in OU if they're allowed. From all the discussion threads, however, there were some solid counters presented.
For instance, Latios/Latias cannot even really touch Registeel without HP Fire, and even then, it can't even 2HKO him even if Latios has 252 SAtk EVs and a +Nature, and Registeel has nothing. The only way they're going to be doing much damage to him is CMing up, and no one's going to give them the chance to get 6 CMs up.
Also, Tyranitar was mentioned as well, since it can take 3 D-Meteors and can Pursuit them out of there.
Steel types in general do pretty good against them, because they lack a good Fire attack, which is the big difference between them and Salamence. Latias is a pretty good wall, but isn't any better than Blissey.
A clear stance on the BL list. Obi suggested playtesting everything that's not OU to define what is BL. Is this going to be upheld?
No. This seriously should not be upheld. I don't really understand how you even decide what's overcentralizing the game in a situation like that. We also need to have a clear definition of what overcentralizing is before we can even touch this.
Deoxys-S in OU?
Yes. It really has not ever done ANYTHING to me in any of my matches, and I really don't feel that much has actually changed since it came into OU. I personally think that people don't prepare for it all that much since its usage is so low for OU, and that's the only reason that it can sweep people's teams. If you actually tell people to prepare for this thing, then it really doesn't stand a chance IMO.
