That Watchog is pretty good, top 5 rearrange in this format could be a pretty sweet smackdown option over Slowking. I also like how it gives an option tot ry for more damage, i think thats a very cool mechanic.
And that Cinccino is the cutest thign ever 0.o
Outside of that, i like Mandibuzz, Krookodile, Swoobat (phat sound...oh my god yes xD), Gothi, both Beartic, Swanna, Levanny, Whimsiscot, Liligant, the Sigilpyhs and all the trainers (aside from Catcher. Hater gonna hate that).
Really, this set looks like it would be fantastic if there wasnt the exsisting power creep going on (Yanmega/Donphan/Reshiram/Zekrom) for strategic, flippy and fun games. And with the new reverse holo they have, allt he better.
