You know, I'm really having trouble deciding what EV spreads to use on these other guys (mostly because I don't really know the metagame). I'll tell you what, I'm going to let you decide what EV spreads to give them. Try to pick whatever spread is the most 'practical' (for lack of a better word) with its nature and ability. If I decide I want a different EV spread later, I've always got extra copies of these guys.
Edit: I'm not on smogon a lot, so I don't have a lot of time to research all the different options for EV spreads. Could you help me out and see which sets are the most popular ones?? Use those EV spreads.
