For anyone that doesn't know, Imprison is a move that when used prevents all opponents from using any moves that the user has. This move is primarily seen as useful in mirror matchups or in other metagames (like 1v1 Spore Imprison Transform Smeargle). I think that it could be extremely useful in double battles, since you can remove your opponent's ability to use game defining moves like Protect, Fake Out, and Taunt. Here's an example 'mon I thought might have potential:

Muh Moveslots (Dusclops) @ Eviolite
Ability: Frisk
EVs: 248 HP / 8 Def / 252 SpD
Calm Nature
- Imprison
- Protect
- Taunt
- Will-O-Wisp

Could it work as a support pokemon in VGC16? If not, could it work in a tier like OU or UU doubles? Surely there's some untapped potential with this move, and I'd be excited to see what anyone else can come up with.
