Well...
Silvally was expected, and it's at least a better name than type:null. What were they thinking. The dragons... meh; a little bit busy, perhaps with all those scales, but I don't care much.
Ribombee, on the other hand, I care; it's really cute, not my thing, but cute; who knows? I might try to use it, but I fear it will end up like masquerain; a pokemon whose design I love, but never use.
Steenee is adorable; I don't even care about having two grass types, I'm using her and lurantis; tsareena on the other hand... I can't quite get where they're going with her; royalty and kicks are not very compatible; I love the information, and the ability (how ever could they not give that to ninetales?), but the concept, it doesn't seem to mesh; the boots, the covered mouth, the proportions... it feels a little haphazard? maybe its movepool will clarify something, since it isn't fighting, despite "kicking" evidently being central in the concept.
Wait, how was that mortal kombat fighter called? I know all the women in that game look the same, but there was one who was royalty and kicked? they already did the chun li/cammy reference in mega lopunny, so who knows?
Grimer didn't end up pointing to hillbilly-ness, only in the design; a fairly boring information, though; how is it that alolan trash makes them mutate but, say, the trash from castelia's sewers doesn't? what do people eat in alola? uranium-235? Muk might be an oil spill, but it still looks so weird; evil as it gets, but weird; I feel the place these two took in the pokedex could have been given to more interesting pokemon, with a more interesting typing.
And is it me or there are far too many pokemon with signature moves? or will those be given to other pokemon too? just today we got three new seemingly unique moves perfectly adapted to their pokemon, and I seem to recall we had some others in previous reveals.
