Ok, here's a set that could work well on any berry holding pokemon.
Uh-uh, I choose you item.
EVs: 256 HP, 256 SDef, 4SAtk
This is my mix, but really, it only works on berry-holding opponents. So, what you do is use incinerate, and that gets rid of the berry. Then, you use Gift Pass, so that they would be trapped with the item and hopefully stuck using status moves. Next, you could do a combination of things. You could use Recycle and gain the Choice Specs back (Unless Recycle doesn't do that, the attackdex doesn't say), or you could start attacking with either Thunderbolt (Water types) or Ice Beam (Dragon types). You choose.
