Just a few thoughts on the few “NU” Pokémon that we have on the list:
Meowstic-M – Seems a lot better to me than Meowstic-F, simply because of Prankster helping him set himself apart from the rest of the generic Psychic attackers in the tier. He even has Thunder Wave, so we might have another Liepard on our hands, albeit one without access to STAB Foul Play, but he makes up for it with some other fantastic moves. Charm, for instance, can be used to great effect on physical attackers, forcing switches and whatnot if he can take a -2 physical hit. Honestly think he’ll be annoying more than anything.
Aurorus – To be honest, probably one of the worst Pokémon to come out of Generation 6, alongside Dedenne. But whereas Dedenne can actually outpace things and hurt them with its decently powerful Thunderbolt, Aurorus has no such speed, only making up for that in raw power with Refrigerate. Unfortunately, Aurorus just has far too many weaknesses to be able to pull off any kind of effective set, so I don’t really see it being able to be used outside of Hail setting or possibly Trick Room teams (blegh.)
Dedenne – The other terrible Pokémon to come out of Generation 6, and man does it show. It’s Fairy type, yet it only gets Play Rough as a decent Fairy move? I know this horse has been beaten to death, but I’m gonna go ahead and give it another whack. Gamefreak really screwed this little guy over, almost as much as they’ve screwed Farfetch’d over the years. If Dedenne at least had Dazzling Gleam he would be somewhat usable, but as he is now his pathetic movepool has relegated him to the bottom of the barrel for NU, at least for me. Who knows, maybe he’ll catch a break in the future, but I doubt it.
Slurpuff – Out of all of the NU candidates, I believe Slurpuff has the greatest potential. I admit, I’m slightly biased as I just adore the little guy, but to be honest, Unburden is just a fantastic Ability in conjunction with Calm Mind (as we saw with CM Drifblim) and Slurpuff has the moveset to make it work. More than that, he has Belly Drum, and with Unburden and Sitrus Berry that creates a monstrous attacking machine that’s only stopped by Steel types. There’s a reason that they gave him such a limited physical movepool, methinks. Anyway, Slurpuff is going to be fantastic, mark my words!
Furfrou – Now this little guy is quite interesting. With a monstrous physical Defense thanks to its fantastic ability, I don’t think Furfrou is going to be something to take lightly. Its Attack is actually quite decent, and it has a pretty good Speed, to boot (102, which is really good for NU.) Has a nice movepool, with Cotton Guard, Thunder Wave, Roar, Baby-Doll Eyes, U-Turn… it’s going to pack some surprises, that’s for sure. One of the ones I’m really going to be looking out for when NU gets going.
If you disagree at all, please, feel free to point out any flaws in my logic. I'm not perfect, of course, these are just my basic opinions.
