Haven't played too much, but am now basically ready to take on Roxie with my team. Got a Dewott (it gained a bunch of levels due to me going 'hey lets do ALL THE MISSIONS' rather than play the game proper, haha. That included the Audino mission, and so it is still ahead of everything else in levels), Stunfisk (because why not? Got it from Dreamworld, may be replaced later on though if I find something I prefer), Growlithe and Venipede. The rest of my team is a Lillipup with Pickup and whatever is the next strongest from what I catch (I am trying to catch everything as I go along).
Missions are a neat addon (better than BW's imo), and Mr Medal is possibly related to Scott given how he acts. =p
