Just for those who don't know, ther tier lists are getting redone sometime in the next week or two. I expect to be seeing Dugtrio become UU. Porygon 2 and Umbreon may become OU. Cloyster and Torterra will probably move up from NU to UU. Rhydon might move up to UU aswell.
These are just predictions, but I think some of them are likely to happen.
I thought in Smogon the classified Rhydon and Porygon 2 as NFE.
