Oh that sounds like fun, I haven't even gotten to meet Pumpkaboo and Goomy yet, hehe.
I've been training more Pokemon than usual, thanks to the Exp. Share and boosted experience for those that you've played a lot with in Amie. Mostly I've been using Aurorus, Lapras, Greninja, Charizard, Talonflame, Skitty, Floette, Skrelp, Malamar, Pikachu, Eevee, Kadabra, Vespiquen, and two Espurr, boy and girl. They range from level 24 - Léo the French that I got on Wonder Trade, that I've yet to decide what to evolve into, to level 40 - Opal the Aurorus that I got myself from the Sail Fossil.
I think it's pretty crazy that I'm actually taking my time exploring everything and playing with my Pokemon, instead of running straight to the next Gym, I guess that's what makes this game so awesome ^^
