The only problem that I speak for within the upcoming usage statistics is Sawsbuck's 41% of usage..... what? Why? This statistic is honestly an absolute disgrace to the NU showdown community. Sawsbuck is easily one of the best setup sweepers right now, and definitely should place a defining role for offense teams alike. Also, it benefits from Gurdurr's rather short stint into the tier as of now; Gurdurr honestly isn't all that great in the metagame now, with Psychic-types (and other good checks to it) present their addition to every team nowadays.
Other that that disappointment, everything else is looking spot, especially on compared to the past, and the top listings (especially the top 10) definitely showcases a good representation of their impact in the current metagame.
