Very noticeable in OU, Contrary Serperior if I remember well. But there are a lot of mons unreleased specially 5th gen mons, but I don't think that will do noticeable changes in OU, they are for almost lower tiers.
@Tobes, but running Shed Shell for only Chandelure isn't centralizing?, it's not the same of running on Ferrothorn or Lugia because they are 1 poke, but running in 3 pokes of the team running an useless item against non-Chandelure teams?
I didn't say Chandelure isn't centralizing. It definitely is. But Chandelure cannot obsolete stall all by it's lonesome, as long as Shed Shell exists. The issue that would have to be looked at is "Does the lack of Leftovers on a handful of Pokemon make stall unviable". I'm inclined to say no. A stall player will have to play better, and might need to adjust a line-up to better deal with an offensive threat. If the
only impact Chandelure had was cauing stall teams or teams with a defensive pivot to run Shed Shell on more than one Pokemon, I would not call that overcentralization. But Chandelure has much more of an effect than this. Its influence isn't cut-and-dry in the slightest. I've always been aware that it was likely that the general public would not like dealing with a Shadow Tag Chandelure meta, and I've also respected the arguments that Chandelure is broken. I can see where they're coming from. But I do not think that argument hinges on "I can't use Chansey or Slowbro without Shed Shell. They deserve to be metagame viable even though they've been UU this gen! Chandelure must be overcentralizing!" Pokemon become viable and unviable alongside metagame shifts. This is how it's always been.
So to put it in more succinct terms: You could make the argument that Shadow Tag Chandelure overcentralizes the metagame, but I do not think that influencing stall enough that it runs Shed Shell on its walls is a strong enough argument on its own.
This topic does seem to be heading towards "Pokemon X is broken" territory though, which I'd like to steer clear of.
Anyway, to shift back to current metagame discussion:
I've still been playing rain, mostly because I've been so busy with WCOP that I haven't had the time to really focus on BW2 and make new teams. Tornadus-T is still probably my favorite Pokemon in the metagame. As long as rain is up it's just such a good stand-alone Pokemon. A fast Taunt is also always useful against Deo-D offense and the like. I do sometimes find myself missing Hidden Power Ice, say when I need to get a KO on Salamence but sand is up, or if I know Thundurus-T is switching in.
A lot of people think that Choice Scarf Thundurus-T is a waste of its offensive potential, but really it's such an efficient revenge killer that I've never questioned the set's viability. It's like if Landorus had been designed for rain teams. Even without a boosting nature or item Thunder still does a lot, and HP Ice and Focus Blast are excellent coverage moves, even on a Scarfer. I'm not regretting running U-turn over Volt Switch at all, since the situations in which a Choice Scarf Thundurus-T locked into Volt Switch against a Ground-type / Jolteon / other Thundurus-T almost never end well for it, especially when considering that nasty Stealth Rock weakness.
PS. Scarftoed is still the best Politoed.
