I really never tought of it and I don't dislike the new designs but I don't really particularly want any.
I'm choosing Chespin because so far its the one who I've liked the most, yet it has to be seen on the final evos.
I'm choosing Sylveon for the sake of having a Fairy-type and because I train an Eeveelution whenever possible.
I suppose that in the end I'll swap Swirlix for a Flying-type because it probably will suck so much.
Now that I think about it, I don't yet have a water transport... Unless Gogoat does it?
I think it's pretty soon to decide teams when there is still no full info on all the Kalos regional dex. I might even include old Pokés to my team.
This is what we know so far:
