Okay, so I know this is just silly, but I was planning on making an Assist Team - 6 Pokemon that each know Assist and one other move. That way, Assist can only call one of 6 moves, increasing its chances of picking a specific move.
Hokey, but damn if I'm not tempted to try it.
Go for it mang.
While in the mansion - my Weavile will be able to use her normal moves along with any of the following at random :
Dive, Crab Hammer, Crunch, Knock Off, Bolt Strike, V-Create, Psycho Cut, Freezeshock
Mainly thanks to Smeargle.
For my chimchar I might make a Smeargle with :
Sacred Fire, Fusion Bolt, Shadow Force, V-Create.
While bringing another pokemon with Strong Grass physical moves for coverage.
