I'll get back to you on this because Pokemazter wrote a lot, but I'd just like to say Golurk is really good right now. I dunno if it warrants specific mentions on C&C, but I've seen it used quite a lot and also used it myself (although mine was a silly set with SR and RP, lol). I also feel that Qwilfish could use an Offensive Spiker set. Separating it from other Spikers is the combination of Taunt + D-Bond/Explosion. Biggest problem would be that it can't fit both Spikes AND T-Spikes in it (unless you choose to run no STAB; but hey, if it's not gonna outlast the other grounded Poison-types what's the point of having T-Spikes?).
Escavalier needs some revision, I know Nas doesn't like SubSD but I still think it's viable so I'll try to get more comments on it. I dunno if it needs a revamp, but I'd be willing to do it in that case.
On the subject of CB Medicham, I know chris is me (may he rest in peace :eek:) used it a lot, the biggest thing it had was Psycho Cut not making contact and 2HKOing Cofagrigus. However it could get deleted, I could see Gallade doing a good enough job with it due to SD and having actual bulk! (although I wouldn't count on it taking a Shadow Ball from Offensive Cofag, lol).
Rotom-C was recently updated, I personally prefer the lure set over the Specs set but I don't have enough experience with the latter.
I see Moltres as having a similar indirect increase in viability as Yanmega after the Froslass ban, simply because that made Xatu much more viable. Biggest problem they had was that they'd have to be paired with Blastoise/Top to get rid of rocks, and that sucked a lot for offensive teams. However, I don't have enough experience with or against Moltres in UU so I'll leave it to you. I do think an Agility set (which has the advantage of not having to get rid of Electrics to actually be used), and a Specs/All-Out Attacker set are viable. I could see SubRoost working with a lure to get rid of Rhyperior (such as Grass Knot Xatu!), although probably not a defensive one like Zapdos's case. I'll stop now because I'm speaking out of my ass, lol.
And about Scyther, I dunno man, I like it. Bulky SD is really good with Xatu support, it sits at a great speed tier and it packs a lot of power with its STABs. I could also see CB and /maybe/ SD+Flying Gem being viable, although I'd have to try them out. As I said, Froslass's departure gives a couple Pokes an indirect improvement by making it easier to get rid of SR. I saw that happen in the Suspect ladder, where Xatu roamed free and made Specs Yanmega much more threatening (damn you Nas :( )
EDIT: OK, I wrote much more than what I would've wanted considering how I started this post, but whatever.
Also as a postscript: I'm interested on your views of Sandslash prior to Sand Stream's retest. I haven't seen it in UU more than twice over the past year, but its reputation as a Spinner in RU makes me doubt of its viability. I mean on the 'not sucking' part, of course.
