Viability doesn’t exist
Pyukumuku —> B-
Making this nom because stall works in this meta and Pyuku is pretty much the face of stall. The sheer fact that it is able to completely shut down such a vast number of non-Sub setup attackers really speaks volumes about how useful this Pokemon is for stall, and stall as a playstyle feels more consistent now than it has been at any point since NU alpha started up, proving that it is very capable of taking on most prominent playstyles to a consistent degree. I honestly don’t know what else to say really so I’ll just leave it there.
Xatu —> A-
Maybe it’s just down to the types of teams that I like using, but Xatu always feels like it comes up short nowadays both when I use it and when I face it. When I use it I find that it has an extremely hard time consistently keeping hazards off of the field, when I face it I always manage to get SR/Spikes past it in one way or another, and with more teams carrying Sneasel in the wake of the Barbaracle ban (combined with the fact that it was already very common on balanced/defensive teams—i.e. the style that Xatu doesn’t do nothing versus) it just feels like it never does anything. It’s very easy to abuse, it can’t take a neutral hit to save its life, it is so easy to pressure, and the metagame just kinda feels like it isn’t very favorable for it on the whole. I feel that there are quite a few ‘mons in A- (plus Cryogonal) which I find to be more consistent than it is, and I think that a lower rank would reflect its viability better than its current rank does.
