Honchkrow@Focus Sash
Insomnia
Naive/Adamant
252 Atk 252 Spd
Extremespeed
Fusion Bolt
Icicle Spear?
Heart Swap
Those are some nice stat boosts you've got there.
Be a shame if something... happened to them.
It's really hard to stop Honchkrow from landing Heart Swap. He can't be spored, sub doesn't block it, and thanks to Focus Sash nothing short of a multi-hit move will take him down. If he gets even one shell smash boost, he can start shredding things with extremespeed and some pair of attacks for coverage. I'm not decided on what two are best though.
Problems: multi-hit moves, ghosts with priority, anything beefy enough to take a +2 extremespeed (or, if your opponent doesn't know what's up and you let him set up 3 smashes, a +6 extremespeed lolo).

252 speed, 252 defense (will play around with the numbers later)
There are two sets I've been running with the same basic idea.
The first:
Substitute
Whirlwind
Spore
Copycat
Get in on something you can spore, set up a sub, whirlwind, and start copycatting. This outspeeds everything in the sun and is basically impossible to deal with if you don't have priority, but guess what most teams have in some form. Sub serves two purposes: if you have a sub up, you can even sleep things with an intact lum berry; second, it's insurance against lucky early wakeups. Can be stopped by scarfed Kyogre, anything with ANY sort of priority, or by switching in Kyogre and then something that beats base 110 speed. This set should probably run Lum or Leftovers.
The other set doesn't roll as hard, but is a lot easier to switch in and get going. It is:
Sleep Talk
Copycat
Mirror Move
Whirlwind
The idea behind the set is to switch in on a sleep move, then start sleep-phazing their team. The biggest danger is you don't know when you're going to wake up, so having something on your team that you can switch to is a very good idea. Sleep Talk can't select copycat or mirror move, and Copycat lets you sweep if you get off a whirlwind and they're out of priority. Mirror Move is just on there because none of the remaining options for non-sleep-talky moves are much use either. This set should always run Sash. Of the two I prefer this one; it's more consistent and gives you a solid spore-target.
To use either of these effectively, you need some answer to Ursaring and other priority; something that can handle Ursaring is also recommended. Suggested options are Ursaring, Ursaring, Ursaring, or Ursaring.
Obviously you also need someone to set up rocks and maybe even spikes. Groudon is a clear pick. Skarmory's good too.
