I've been dedicated to the Suspect ladder as of late, and I can't believe how much the metagame has shifted. In the beginning, I saw like 3-4 Suspects on every team with some Steel walls (I have to admit, my earliest Suspect team was sadly similar to that description). Thankfully, things have calmed down, and with Deoxys-S gone I've noticed a more fun metagame. Apparently, Garchomp hasn't hit the ladder as hard as I thought it would. I was expecting it to be taking the role of the Swords Dancer on every team, but I mainly see Scarf, Band, and (not joking) Support sets. SD Chomp is still around, but it's not as abundant as I'd expect it to be. Usually, I can just switch Latios in and kill it. Yache Berry isn't as common as it used to be due to Lati@s being so common, so it's been repalced with Haban Berry (I find it a waste since Latios still kills Garchomp through Haban Berry).
I really like Skymin, especially the SubSeeder. It can kill Latios with multiple flinches, still outruns things like Gyarados even after a single Dance (assuming Adamant), and is just generally badass with Seed Flare. Offensive sets have a harder time being effective, what with Scizor and co. being common. I guess they could threaten the SubSeeder, but at least SubSeed Skymin can outstall things like Metagross without Agility or Ice Punch granted it hits it with Leech Seed on the switch. I haven't seen any Specs Skymin, which is cool since they'd be really annoying to deal with (totally managable, however). Scarf and Substitute are the most common ones I see.
Latios is just plain awesome. The raw power it has with Draco Meteor tears pretty much anything that doesn't resist it a new one, and even things like Bronzong and Metagross who are supposed to be counters have trouble switching-in multiple times due to lack of recovery as well as being easy set up fodder for many other things (Manaphy comes to mind, especially if Metagross lacks Thunderpunch). Manaphy isn't that common at all, at least from experiences, so I won't voice my opinion on it. From facing it the few times I did, however, I noticed how Latios and Skymin just basically...kill it. SubSalac is something that seems like it could be problamatic. Sort of like a stronger (?), yet slower SubPetaya Empoleon.
I've seen one Latias, and it didn't do anything memorable. I'm guessing it could do better vs. Skymin that Latios could, though Latios's higher stats in offensive would make it a better choice. Honestly, I think people like Latios because it's blue

. I've seen some Dual Screeners, though Latios is superior if the team is offensive, due to Memento (which is REALLY annoying, since I'm seeing that Latios + Gliscor + Metagross combination again).
As for non-Suspects, Skarmory is just incredible. I thought it was just a stupid, hyped Pokemon at first, but it really is effective. It averages 2 layers of Spikes per game, and walls the hell out of Latios, Skymin, Scarf Garchomp, and even takes on things are used as counters to these Pokemon, like Metagross, Bronzong, and Mamoswine. There's little for me to say other than that it is, in my opinion, the best Pokemon to use as a defensive buffer in this stage. It gets the job done, it gets the Spikes out, and it does all this while having a 50% recovery move, a way to remove stat ups, and even a moderately powerful 120 STAB move to abuse (meaning that it doesn't just stall opponents out, it can even go offensive and KO them with some SS and Spikes damage). It fits on basically every team, which is awesome since I'm gonna try stall later and definately am looking for giving Skarmory a spot.
Bronzong is such a beast when it comes to stopping Latios, though not as effective in my opinion. This is due to the fact that it has
no reliable recovery. That
really hurts, especially since Draco Meteor is still doing uncomfortable damage, despite being resisted. I used Macho Brace Bronzong earlier on, and with Trick, it could stop special AND physical threats, which totally screwed over things like DD Gyarados lacking Taunt. Metagross is common, offensive or defensive, which is nice because that's just more opprotunities for Skarmory to come in and set up Spikes. Blissey is coming out of the grave to stop Latios and friends, but sadly, Latios can fuck up everyone I've mentioned with Trick (bar Macho Brace Bronzong. There it ends up screwing itself over). It's always nice to have a Leftovers on your Latios for an extended sweep =-)
Offensively, there are a few Pokemon I'm really impressed with. Mamoswine is like...
the Suspect killer. Every Suspect bar Manaphy is easy picking for Mamoswine, and while Steel-walls that float wall it, there are ways around that. Late-game Dancers like Gyarados and Tyranitar are
very effective, despite being unable to outrun Skymin (if Gyarados runs Jolly it does outspeed it, however). Tyranitar is especially effective, mainly since it can take Draco Meteors and such and outrun things like Latios with a Jolly nature after a Dragon Dance. It also handles Steel-walls that don't invest in Defensive EVs handily. For example, Skarmory takes about 80% from Stone Edge and Fire Punch with a boost, meaning that with a little residual damage; it's dead. Crunch rapes Latios and friends, and Manaphy takes 81% minimum from Stone Edge after a boost. Skymin is the only Suspect that really bothers it, but then again, guess who comes back for some fun? Yeah, Skarmory.
As for anything being Uber or not, I ironically find that with all the Suspects in the same metagame, they sort of balance each other out enough to prevent any of them from truly becoming Uber. Maybe that's just me trying to keep all the Suspects together, but yeah, I'm enjoying this metagame a lot ;D
