Are there any Water type Pokemon you would like to try, that you haven't been able to use yet?
Pretty much all the fifth generation Water types.. and all of the other fifth gen Pokemon. I can't say how big expectations I have for it, since there's been quite a lot of hate for the Pokemon of the fifth gen, but that shouldn't really affect how they function in battle, so what's a bad concept against that? As for any generation I've played, the only one I can think of at this point is Milotic because I've never had the patience to catch a Feebas, but other than that, not anyone I can think of at the top of my head. I would say any event exclusive Pokemon, but except for Phione/Manaphy, the only one yet is Keldeo. All in all, I'm pretty content with the Water types I've used so far, and they're pretty much the ones I'm more excited to use, since I already know what they're capable of, and already love them.
