I think I like Mild best. Since the water, grass, electric, and fire resists are really useful. Being a little weaker to bullet punch isn't fun, but I guess it depends on what you want.
I made a team just like that before, with Dragonite and Azumarril on the same team. Priority to kill the fast teams, then use a SD pokemon or some sort of wallbreaker to cover the slow ones.
Emolga is really bad. For in-game though it would probably work. In competitive the baton pass set is largely outclassed, and as a sweeper it is also largely outclassed.
In-game Substitute really isn't very good. Otherwise you can pick any of those other moves. Mixing and matching could be fun. Try to sweep with it once it becomes overleveled.
