Me too!! The designs look good but the animations are a bit weird, I have to get used to their weird hand movements I guess.
I have never used Kecleon, Breloom, Mega Manectric or Kangashkan!
However, I do plan on using kangashkan. I'm nearly done with the breeding process. I wonder how it will turn out.
I battle using these: Garchomp, Greninja, Ferrothorn, Togekiss, Machamp, aegislash, rotom
And some megas I use are these: Mega Gardevoir, Mega Lopunny, Mega gengar
I mix and match teams most of the time, which is pretty bad. It's better to stick with one team, but I just have so many trained pokémon, It's just kinda choosing one primary team.
