Ok, so I have an interesting thought.
As anybody who has ever attempted to use a stall team knows, calm mind reuniclus is a huge threat, so I had a thought about a possible solution. Although gimicky and very circumstantial, what if one of your team members ran skill swap (such as Mew or Blissey). Not only would this deal with reuniclus but it would also counter poison heal gliscor. My main issue with it is that you need to sacrifice a valuable move slot for it. In the current metagame, your opponent can't really abuse skill swap much and it has other benefits such as against Conkeldunker (sorry for spelling) and trappers.
Does anyone have any thoughts or suggestions - this was just theory moning of course.
