Jabba in the house about to drop his CRAZY VIEWS on this topic. First I'll address all the suspects and how the metagame is without them. Then I'll go over what I feel are the biggest threats in the new metagame.
Gallade - The loss of probably the best STAB Close Combat user was pretty big. The other fighters (Primeape, Hitmonlee) aren't really used that much. Don't know why. I figure Primeape would be pretty good right now with all the sleep running around. This has allowed teams to generally not have to worry about doubling or even tripling up on their fighting weakness. Nothing yet has proven to be as scary as this guy yet with one turn of set up, though I'm guessing something might pop up soon (I've seen teams having difficulty handling Quick Feet Ursaring maybe it's worth a shot!?). All in all i think the metagame is definitely a bit better with this guy out of the picture even if it allows my douche opponent to use Registeel, Clefable and Chansey all on the same team.
Abomasnow - I haven't seen any teams using Snover as a replacement, so I'm wondering how it would fare. While auto-weather is definitely the breaking point for Abomasnow I still think the 100% Blizzard off of pretty alright special attack is pretty fucking hard to deal with. Then on top of that it gives hard hitters like Glaceon the same opportunity. I definitely think a UU without Hail is a better UU.
Staraptor - This motherfucker being made suspect was definitely amazing. It was hard as fuck to make a team and cover for Staraptor. I never faced the Sub Life Orb set either which is probably a good thing I'd imagine. I haven't seen any normal types really step up and take Staraptor's place. You'd think Tauros would be a prime candidate but I don't think I've seen a single one yet. UU is definitely better with the scene bird.
Raikou - Eh. I thought at first that Raikou deserved to be suspect. But seeing the way the metagame has shaped up has made me rethink it. I will admit that the metagame seems a tad bit electric weak allowing even weird things like Manectric and Raichu to occasionally have their fun, but I don't really think Raikou would be too much of a burden on the metagame right now. I mean right from the get-go he had his counters and I'm personally under the belief that the only reason he was voted suspect were just preconceived notions based on Raikou's status in past generations.
Froslass - Froslass is one super annoying dick and the metagame is probably 100x better without it. But I don't think that makes Froslass bl. It's not "broken" by any sense of the word. Setting up maybe an average of 2 layers of spikes a game before dying is not what I'd consider bl under the support characteristic. I hope people see through the annoying factor and realize that what Froslass does, other pokemon can do too, but they're just not annoying when they do it.
Crobat - Crobat isn't even close to bl and him landing suspect is a tad ridiculous. Fast taunt + roost + weather may be pretty damn good, but it's not broken. Plenty of things can set up weather damn well. Uxie is probably a prime example. Yawn + sr + screens + weather + so many other things. If Crobat is suspect under the support characteristic then Uxie should be a guaranteed bl.
Honchkrow - Honchkrow is badass and as king I deem him best Pokemon in UU. Insomnia is pretty sweet, but the likelihood of Honchkrow having insomnia also makes Super Luck a nice choice. And trust me, Super Luck is an amazing ability especially when paired with night slash and I'm not going to lie it has saved my ass on a number of occasions. Fighting + Dark + Flying gives pretty sweet coverage and Honchkrow can really hit like a motherfucker. Recently I've seen a giant spike in Krow usage too with all shapes and sizes being used. Life Orb seems to be the most popular and in my opinion the best, but there have also been a lot of banded krow's showing their faces and I even saw a ScarfKrow which really gave my team a shitload of trouble. Krow is definitely awesome, but I just want to clarify it definitely IS NOT a suspect. The only Pokemon that may come close to that is: (oh and the mexican duck but that one comes later)
Shaymin - Life Orb and Subseed. Both sets are scary. I'm personally partial to the Subseed set because it's really pressed for counters while it sticks around forever while the life orb set can be easy to play around at times. I originally had the intention of nomming this thing for suspect the next time nominations came around, but I think I've changed my mind of late. Sure it may be the best Pokemon in UU (my fanboyism of Honchkrow excluded) but a tier always has to have a best Pokemon and I don't see this one being too much for the game to handle. Subseed really is a bitch though. Stall teams beware, it'll annoy the fuck out of you.
Spikers - Oh no Froslass is gone who do I get to spike from this terrible pool of spikers??? Stall teams have a formidable spiker in roserade I've noticed, though at times it can be extremely difficult to bring it in. For offensive teams I've used I've tried out omastar and smeargle. Omastar flat out blows, but Smeargle is even better than Froslass in my experiences with it. Running a set of Spore/Endeavor/Sr/Spikes you have so many options and so many ways to lead yourself off to a good start unless your opponent is an asshole and leads with taunt drapion. But usually at the very least you're pulling spore + sr which is pretty impressive. However a very good portion of the game doesn't run a lead that they're willing to sacrifice to sleep so you can pull spore + sr + 1 layer or if you want to cripple someone you can always pull that endeavor off. I definitely have love for the Smeargle, hasn't done me wrong yet.
Drapion - As mentioned above, Drapion can be a pretty impressive lead, being able to handle almost all setup leads with froslass and crobat out of the picture. It can also fill the role of Swords Dance sweeper pretty well or if you're a douchehead like one unnamed person on the ladder you can use scope lens and get 7 crits in a row which is pretty sweet if you're not the one being critted. I've always been a longtime fan of drapion in OU and gouki has made fun of my unfounded love for the weird scorpion, so it's only fitting that I also love it in UU. Personally I've resorted to running a max hp/max sp. def careful sd/3 attack set that's odd but kind of works. Or at least it keeps things like shaymin and roserade in check long enough for me to actually get in a position where i can outright kill them.
Roserade - Badass mon. However I just want to come out and say that Life Orb Roserade is fucking amazing and people need to try it out. I personally run a set of Sludge Bomb/Leaf Storm/Grass Knot/Rest, but if you're afraid of steel types there's nothing wrong with running hp fire > grass knot outside the obvious loss of 1 speed. Give it a shot it's pretty awesome.
Mismagius - Subcm mismagius is definitely completely underwhelming. I've been using it and quite frankly it rarely manages to pull a kill. However I can't drop it because I need the spinblocker, but if I didn't I would get rid of this fucker in a heart beat. Also I haven't had one of these pull more than a kill against me either, it really isn't that threatening.
Rhydon - LonelyNess has been ripping ass with this guy. I feel like a Rhydon stone edge is one of the scariest things in the metagame right now and I also feel that people are unprepared and aren't making sure they carry a rock resist. Though that doesn't really matter anyway since almost every rock resist in UU is going to be decimated by an EQ anyway. Yeah he's scary, but don't try him out since my team is rhydon weak.
Rain - As deadly as it was before the UU/BL merger if not deadlier with the ridiculous addition of that goddamn Ludicolo. Ludicolo is a pokemon I actually may consider nominating for suspect. Prior to the merger, Kabutops, Omastar and that weird fish thing whose name I forget dominated the Rain Dance market and a few people (including me) were calling for at least Kabutops to be moved to bl. Ludicolo in the current metagame blows all 3 of those out of the water (pun five!). Bitch is scary and I haven't come up with a reasonable way of dealing with it yet.
Spinners vs. Spin Blockers - I see a lot of people still trying to use Claydol as a spinner, which from what I've noticed so far is extremely extremely useless. In UU, there are almost zero spinners that can break the spin blockers. I say almost because some people have gotten crazy and started using foresight hitmontop just to get rid of spikes. I'd rather just make a team that deals well with spikes than waste a slot on such a shitty set, but hey to each his own.
Stall - There's a lot of talk recently by some people about stall being insane right now. It's not. It's far from insane. I'd say stall right now is "pretty good." Personally I think stall isn't even close to as good as it is in OU. The problem with UU stall is that it isn't a guaranteed win over Balanced teams. In OU, from my experiences at least, if your opponent was trying to break your stall with a balanced team, they would fail 9 times out of 10. However in UU, stall is easily broken by a balanced attack. It doesn't require a team of 6 life orbed mix sweepers to beat.
P.S. Clefable is a bitch
