Sorry, I didn't make that quite clear, and I only meant to respond to part of your post.
If the opponent has Smeargle + Bronzong, and you have, for instance, Smeargle + Lucario, the opponent will expect your Smeargle to use Fake Out. This is because believes your Lucario is just a damage oriented pokemon and your Smeargle is just there to stop something from targetting it. He also believes that you won't Dark Void, because HE thinks YOU think he will be using Fake Out, and won't risk a 0 priority move, and because HE thinks YOU think he has Lum Berry on Bronzong (Which he probably does anyway). Therefore, the best option he sees is Follow Me; even if you use Follow Me, nothing is lost for him. Didn't capitalize to be condescending, I just thought that part would sound weird.
