Yep, we got our first batch of post-Bank usage stats, and what immediately jumps at one's eyes is CHARIZARD AT NUMBER SIX. The scary thing is, BOTH of its mega evolutions can be credited for that massive leap. Mega Charizard X is often mentioned as a nightmare to face, what with its STABbed, Tough Claws-boosted Flare Blitz and Outrage, but its Y counterpart is actually slightly more popular. And I can't blame anyone using it, either. STAB Drought-boosted Flamethrower/Fire Blast, STAB Air Slash, and Drought-boosted Solar Beam off this ginormous special attack stat? Why the heck not? So instead of putting up with a crappy Pokémon without even knowing it, the little kiddies get a choice between two nigh unstoppable forces. Wonderful.
Aside from that... holy shit Rotom-W's lead over the rest of the field is huge. Nothing else can get over 16%, but Rotom-W? Just shy of 22.5%. And keep in mind, this is a former big rain abuser that has no rain to help it anymore. Sweet baby Jesus on a pogo stick. Aegislash is still holding on at #2, which gives me the opportunity to ask: would it have been uber last gen? In gen 6 Ghost/Steel is weak to both Ghost and Dark, which were neutral last gen. Just like that you just doubled its amount of weaknesses. Steel/Psychics have the same issue, and they suffered tremendously. Aegislash, though, doesn't seem to give a fuck. Of course its hypothetical gen 5 tiering wouldn't have been set in stone, since just about every ban had to do with weather in some way, but that's something to think about.
Also, gotta love how Genesect outranks Lucario, despite there being not nearly as much of a consensus for it in the ongoing suspect test. Just how good is Mega Lucario? Well, over 90% of all Lucarios have the Lucarionite. At first glance this is perfectly normal because Mega Lucario vastly outdoes its vanilla form in every way, but remember, you can only have one mega evolution. This basically means that running regular Lucario with another mega evolution is almost never done. It's all or nothing with this bad boy. And while we're on the subject of suspect testing, where is Deoxys-E, you ask? #69, not even close to the OU cut-off line. Yeah, pretty sure I see a BL tiering in its near future should that trend keep up. Mega Gengar's ban really shook things up for the species' use, with a measly #20 (measly by Gengar's standards at least).
When news of the weather nerf broke back in early October, I thought Venusaur's time in OU was done for, mega evolution or not. That #18 ranking definitely proves me wrong. Thick Fat is just that much of a perfect fit on it, leaving only two weaknesses to Psychic and Flying. Increased defenses also go great with Giga Drain, and it actually has a good reason to use Sludge Bomb now.
Mandibuzz is our HUGE BREAKOUT star this month, going up from #96 in November to #19 in January (remember, December's stats were unreliable for various reasons, hence why I'm not bringing them up). Yeah, the Defog buff definitely helped, but that alone couldn't be the cause, since Defog used to be an HM, which means a pretty good learnbase. No, it's another move that Mandibuzz only obtained with X/Y that really seals the deal: Foul Play. It's an absolutely perfect Pokémon for it, with massive defenses and worthless attack. If you told me, just a month ago, that Mandibuzz would be more used than Gengar, I would've laughed you right out of here.
Breloom went from top 10 threat to mid-OU. Yes, it's still a very respectable #28 despite everything that happened to it. Spore doesn't work on Grass-types anymore, Low Sweep is no longer compatible with Technician, and worst of all Talonflame is now a thing. This last one resulted in a rise in Focus Sash use, but it still hurts like hell.
As for Trevenant, it lost some steam since November, but it's still going strong at #34. Popular moves on it have changed a great deal: Shadow Claw, Substitute and Curse saw a great drop in use (shame, it was awesome to see Ghost-type Curse do something for a change), while Will-O-Wisp and Horn Leech replaced them in order to stop the likes of Tyranitar and Scizor from threatening it.
Smeargle looks all set to return to OU, as it's one of the best users of Sticky Web, along with Galvantula, who's riding the OU train as well. Looks like Gamefreak knew what they were doing when making this move and giving it to certain Pokémon.
Clefable is still holding on as well, which really suggests adding the Fairy type to anything will instantly propel it to new heights. Of course it started from far behind because mono-Normal was just terrible, but to be fair I always had a soft spot for it due to its versatility.
Another unexpected guest is chilling around the OU cut-off line: Bisharp. Yes, Bisharp. It took some time for people to discover its true power, as it was still well off the top 100 in November, but it really is a vastly improved Pokémon. Perhaps the most important aspect is the fact that Steel no longer resists Dark, which results in greatly improved STAB coverage, as it no longer needs a Fighting move to beat Steel-types - most notably Aegislash, which it counters quite effectively. This allows it to run a set with Swords Dance, Sucker Punch, Iron Head and Knock Off, which is bog standard on this guy. Iron Head also murders Fairies, and choiced Talonflame hates it when locked into Brave Bird, because you know a Swords Dance is coming. (Edit: Forgot to mention, Defiant got an enormous buff by virtue of Sticky Web and Defog triggering it, and, well, Sucker Punch doesn't really care about the speed drop either way.)
So we got the likes of Mandibuzz, Trevenant, Clefable and Bisharp making their niche into OU, on top of numerous other expected newbies and megas. And something's got to give... what's stuck outside of the OU cut-off line this month? First is Thundurus-I, which was uber last gen. Man, the loss of rain REALLY hurt it, didn't it? Then we have perennial bulky Water Vaporeon, which just isn't cutting it anymore, it seems. Latias is also going away, especially with Latios struggling more and more itself. Remember when Latias was suspect tested late in gen 4 and it was deemed overpowered? Things change FAST in this game. Terrakion was a popular subject of conversation in gen 5 OU... it'll be one in gen 6 UU by the looks of it.
Further down we have Hydreigon, Landorus-I, Jirachi, Deoxys-E, Kyurem-B, Jellicent, Metagross, Celebi, Keldeo (who was the target of the last suspect test last gen IIRC), Deoxys-LG... the list goes on and on and on. Former weather abusers were especially crippled, with Manaphy, one of gen 5's first bans, just barely making the top 100. Speaking of weather, Politoed still ranks at a decent #74 despite the nerf. I liked to say that if it remained OU, it'd be proof that it should've been banned all along. Do you think #74 is good enough to prove that point?
Oh, random thought: despite only one Pokémon breaking the 16% mark, only 49 Pokémon meet the criteria for being OU, which is a few less than last gen, which had a metagame overcentralized around weather. I can't decide whether it's good or bad.
As for ubers, Xerneas is no longer found on over half of all teams - that honor is exclusively reserved for Arceus, to no one's surprise. And if you ever needed proof of just how many dragons lurk in ubers, Fairy ended up within a hearbeat of being Arceus' second most popular type, falling barely short of Ghost and Steel. No doubt if Xerneas wasn't around, Fairy Arceus would be crazy popular. Enough to compete with Normal? Who knows?
Mewtwo remains #3 (combining all Arceus' forms), as should be expected of a Pokémon with two great megas. With Mega Mewtwo Y's ability to hit through physical defense with Psystrike, I'm still a bit surprised Mega Mewtwo X isn't totally obsoleted. I suspect STAB Drain Punch has a lot to do with it, as it's by far Mewtwo's most used physical move.
Behind it, Kyogre still holds on to the title of "best of the rest", because even though endless rain isn't a thing anymore it can still abuse five turns of rain pretty well itself. Groudon, on the other hand, suffered greatly, ending up at #9... behind both Blaziken and Ho-Oh. Kangaskhan's ban in OU really opened the way for its discovery in ubers, where it outranks terrors such as Dialga, Rayquaza, Deoxys-FR and Palkia. Kinda puts that ban in perspective, am I right?
Final thought for ubers: some of its players aren't exactly bright sparks. 6% of Blazikens have Blaze, 10% of Ho-Ohs and 28% (!!!) of Lugias have Pressure (true, Defog is illegal with Multiscale, but Defog only gets 4% usage anyway), 9% of Scizors don't have Technician (which is a LOT more than those who don't have Bullet Punch)... yeesh.
So that's it for this wall of text. Ciao!
