Top leads: Deoxys-e and Darkrai, by twice as many usages over #3 on.
The RSE trio continues to dominate the top 3. The decline of usage after Groudon is steeper this month than ever before. Kyogre's iron-grip on #1 is loosening, and he will most likely heed the #1 seat to Rayquaza by next month! Last month, Kyogre was used approximately 10.6% more often than Ray and 46.4% more than Groudon. This month, his lead over them has shrunk to 1.5%(!) and 6.6%. Kyogre hasn't gotten any worse; many other pokemon have just gotten better.
Rayquaza's usage hasn't slowed down one bit in response to ScarfDialga, but his common movesets have splintered off. SD is no longer the standard Ray set - DD has gained a significant lead (although continue to expect SD). Mixed sets have also been rising in popularity, and I expect them to rise throughout the month.
Support Groudon has dropped in favor of Rock Polish Groudon - who fits well in the current special, speedy metagame. The metagame is evolving to deal with the potent threat RP Groudon posed, and many Groudon users are mixing and matching various sets in order to counter.
Darkrai needs little explaining. Scarfrai functions as an excellent anti-lead and can usually incapacitate at least two opponents to Dark Void and Trick before going down. The Nasty Plotter can sweep a team clear if you're not ready for him. (I personally have had little trouble dealing with them though - bar misses or critical hits, which can end the game - and not much success using it, although I have been using the one attack variant)
BUrestalk and support Dialgas have taken a back seat to Choice Scarf Dialga, who is keeping a myriad of current metagame threats at bay with its handy defensive typing - foremost among them being Rayquaza. ScarfDialga is the primary reason Rayquazas are running DD.
LO Mewtwo has become tremendously popular this month - most people are probably using him as a Deoxys-f substitute - Mewtwo's superior movepool and durability make him a better choice in a metagame filled with scarfers, priority moves, and "everything else" (which usually won't die in one hit). *Unfortunately, unlike Deoxys though, the standard LO Mewtwo will never beat Blissey one on one without Self-Destruct.
Choice Scarf Palkia continues to be the most popular variant by far (well over 60%). Recently though, it hasn't felt as threatening as some of the other major threats. It might just be misuse though (more Groudons and fewer Kyogres certainly don't help, since most Palkias don't, although they should, run Fire Blast) I see the other variants becoming more popular this month (and while I have no proof, I could swear Lustrous Orb usage was increasing, but maybe I'm underestimating Spacial Rend's power).
Standard physical wall Lugia usage has risen slightly this month, probably in response to sweeping-oriented Groudons and the rising popularity of Scizor. The CM variant has also picked up some steam - they either succeed completely or fail utterly, in my experience, usually the latter.
Scizor's usage has skyrocketed since the addition of Bullet Punch, making the trapper set more threatening than ever. Many Scizors now choose to eschew Roost though for Brick Break - partly for Blissey, partly to destroy screens.
Deoxys-e's usage remains steady this month - the standard spiker lead follows the same premise as in OU - get down SR (and maybe spikes) at all costs. Most run Focus Sash, but a few were desperate enough to run Choice Scarf to stop lead Scarf Darkrais from stopping them.
Deoxys-f took the heaviest hit this month. The SR lead set is completely shut down by Deoxys-e, and Bullet Punch/Pursuit Scizor, Extreme Speed Ray, and a number of scarfers who can all shut him down one way or another (Darkrai, Dialga, Palkia) hamper his attempt at a rampage.
Like Lugia, Giratina's usage has risen a little this month, probably to deal with the same threats Lugia is tackling. The great wall set continues to be the most dominating, although there are more CMRestalkers this month (as there should be, since the Wow/Restalk set can very easily become set-up bait).
Blissey's usage rose this month - just in line with Latias' decline too, since Blissey has an easier time handling many of the current special threats. Most of them are choiced users who don't pose too much of a threat to Blissey (and Darkrai). Blissey also has an easier time dealing with Scizor. Coverage over Kyogre is also getting covered by other things.
Almost 100% of the time Mew is a straight speed BPer, usually without outside screen and rock/spike support. Irritating to play against, actually, but people are finding ways around it, so I don't expect it to climb any higher.
Metagross and Garchomp remain about the same. No significant changes. Interestingly, Garchomp's usage has dropped a bit while Metagross' remains constant.
Other comments: I could swear there were more Tyranitars this month. 19th doesn't seem right. More people should use Giratina-o - those ground and fighting immunities (and all those resistances) really come in handy, and even a straight-up attacking stat is monstrously powerful. It takes resisted hits like a champ - SE hits are pretty damaging though (which is why I've been running a Sub/Draco Meteor/Shadow Ball/Outrage set with maxed attack stats). For some reason, there were a bunch of Ho-ohs this month, many without Groudon too. Anyone want to take a stab at that? Finally, Latios usage has plummetted. He's 25th now, far below standard. That sounds about right. The special attackers of this metagame outclass him.
