Only design that I haven't really liked is the Derpard (Electric Lizard) Looked more like a dog to me, than a lizard. Just hope it's evo's (assuming it gets them) looks better.
Gogoat, Robbin, and Po, look bad-ass as hell. Will hopefully be team member. My plans for teams usually change as I'm actually playing the game. Like in Black when it first came out, I had planned to use Purrloin, but I struggled using her in battle, plus I had a Sandile (which originally I didn't plan on using). Sandile turned into a beast of a pokemon, and Purrloin, sadly I might add, was dropped.
So far I liked most of the sixth gen. Which is pretty good going.
Sic vis pacem, para bellum. Don't make me HM01 you.
