Dusclops was good at the end of BW1, you could run a more traditional stall team and worry pretty much only about Terrakion and be set. Stall is admittedly much harder in BW2, and that's pretty much only because of Genesect and the metagame shifts it made. Stall has always had an issue with sun and Deoxys-D spike stacking. In the past you could get away with it because sun was uncommon (even in early BW2) and so was Deoxys-D. Genesect capitalizes on these weaknesses and makes them much worse, now your pretty much forced to run rain stall or Heatran to deal with it. Even if you do manage to deal with those 3 big threats, you still have you contend with offensive dragons, Latios, volt-turn, swords dance scizor, Terrakion, Breloom. The list goes on, I have no doubt stall is possible, but it is much harder than we are use to. Hopefully in a few months once the metagame cools down, stall can have a weight lifted off its shoulders as stuff falls to OU.
Also you have said you are running a stall team, do you mind sharing, currently I am testing a ton of different styles at once and I change my team every day so I can't exactly share.
I've got two full stall teams I'm working on at the moment.
This one brought me up to ~1860 or so:
Chople SpDef Tyranitar (to beat other weather and kill Tornadus-T)
Taunt Jellicent (spin blocking, Will-O-Wisp and Taunting other stall)
Amoonguss (HOLY SHIT MORE PEOPLE NEED TO USE HIM, FULL STOP TO ANY KELDEO AND ANY BRELOOM)
Offensive Starmie with Rapid Spin (spin/cleaner)
Skarmory (Spikes - a must for stall this gen)
SpDef Heatran (Stealth Rock and FWG Core)
And I'm working on a rain stall team now:
Defensive Politoed
Tentacruel (Toxic Spikes)
Ferrothorn (Spikes and Leech Seed)
Bronzong (Stealth Rock)
Annoyer Tornadus (saw it in an RMT - normal Tornadus with priority Substitute and Taunt + Hurricane and Focus Blast - an absolute monster of a cleaner)
? ? ?
Trying to find something to go here. Since I have all three hazards, I'd like a spin blocker. I'm testing out Spiritomb now but I'm not too happy with it.
On the subject of stall, how do you guys deal with Breloom. I have yet to make a stall team that doesn't simply have two full Breloom counters which is a huge inconvenience. Your first counter gets puts to sleep and if you only have one counter and try to sac something else to Spore, if you mispredict you're totally boned :/
