Everybody has their own reasons for picking a team. You know mine, but in that sense there's a few that I tend to favor a bit more, with my main six being Chesnaught, Greninja, Talonflame, Aegislash, Dragalge and Carbink. I'm doing it for the type spread, and I'm only missing Ice as one of my favorite types.. And I just realized, I can switch up four of my favorite six, and I can still have the same types. Switch out Chesnaught, Greninja, Aegislash and Carbink for Trevenant, Barbaracle, Pangoro and Klefki and you have the same 8 types! xD It's sad though that there's only a single Poison-type introduced.. What I could do is use Charizard X and a Crobat and I'd have rotated my entire team for the same types, but I don't even have Charizardite X (I've got Y for that time in which I'll run a Sun-team xD). I've literally replaced my Aurorus from my main team for Carbink just a few days ago..
I've got an additional team, and it consists of Snorlax, Swellow, Umbreon, Shelgon, Lapras and Drapion. So the only things you use that I don't have is an Azumarill and Espeon, but I've got an Umbreon so that's fair.
