Just one question: Why the hell would you ever sacrifice one (or even two!) moveslots just for stopping Smeargle?!?! It isn't SUCH a threat :o
Lum/Chesto Berry, priority moves and maybe Hail / Sandstream to knock out sash. But you don't need to base your whole team around stopping DV Smeargle '_'
Second thing is: How could you ever destroy things like Dialga or something like this.
Maybe your leads are countering every set-up move, but it won't help you much...
As I mentioned, there are a lot more ways to counter things like Dark Void, Trick Room etc.
