I saw a thread about the november statistics of UU and RU, but not of NU. The tier is getting popular, and awesome as well, so I don't see why there shouldn't be a thread about it.
To OU: Dugtrio, maybe Gorebys
To UU: None
TO RU: Slowking, Lanturn, Rhydon, Scolipede, Snover, Braviary, Swellow, Klinklang, Magneton, Rotom-F, maybe Absol Cryogonal, Quagsire
EDIT: I realised I forgot to put Magneton in the NFE usage.
EDIT2: I realised I forgot to put Magneton, Absol, Cryogonal and Quagsire among potential leavers.
EDIT3: You probably know it already, but Snover is BL, so he won't be RU.
