I battle a lot on Marriland forums, and the smart battlers tend to use Stealth Rocks or Spikes. Some battlers use Toxic Spikes, but they seem to be less experienced.
I'm not saying I'm a top notch battler or anything, but it seems like SR is being used.
As far as status I'm seeing a lot more WoW these days, with some Toxic/Twave thrown in.
Blissey clerics are dead (I haven't seen one), most come in the special wall + boltbeam wave boiled version.
Priority moves have come back strongly. Mach Punch, Bullet Punch, Fake Out, Quick Attack, Sucker Punch, Ice Shard have seen increased usage.
I'm acutally in the process of writing a threat list/ commonly seen pokemon guide for Marriland forums, I'll probably post it here. Most of you probably would bash me for omitting Azelf and Cressy, but currently the accepted metagame over there is no ubers + no legends. Not sure how much it would help here, but still could be useful to some.
So, my experience is limited to not facing Cress/Azelf/Manaphy. But their effects have been felt, as I've seen some walls (Bronzong) set up Reflect, Light Screen. Seems they may see more use now.
Focus Sashes and Choice Scarfs are everywhere. Some CS'ers are predictable (Garchomp), others somewhat predictable (Porygon-Z), others from left field (Zam, Weavile, Hitmonchan, Breloom)
Focus Sashes have been seen on everything too. With a lack of sandstream being used by most teams I've faced, you see Focus Sashers in the middle of battle, not just with the common lead threats (Gar, Weavile) Sandstream should see more play, with some people entirely banking on FS to save them (Agility users, etc)
Surprisingly, there has been a lack of Heracross. Might be breeding issues. Also surprisingly I haven't seen many Ttars.
Most common pokemon showing up are Salamence (specs), Gyara(Bulky+taunt)-Vire (usually pure, not mixed), Weavile (revenge and lead), Blissey.
Thats about all I can think of in the top of my head.
