Nominating Ninetales for S Rank
"Pokemon who can support other Pokemon with very little opportunity cost ("free turns")."
I can't see a way where Ninetales doesn't fit this description. Ninetales sets up an Automatic Constant Sunny Day for zero trade off. Drought could be argued to be the largest support any one pokemon can bring and it doesn't take Ninetales any turns to set it up; it just has to come in. Chlorophyll and Fire-type boost alone should push Ninetales' support rating to S Tier. If Politoed is S Rank(which it definitely is) then so is Ninetales.
Nominating Terrakion for S Rank
Pokemon who can sweep or wall significant portions of the metagame with little support
Terrakion can demolish any wall in the OU metagame. Not only that but it can also sweep entire offensive teams lacking solid priority. Between sets like SubSD destroying the likes of Gliscor and Slowbro and sets like SubSalac and Rock Polish cleaning up whole squads of offense I think its obvious Terrakion belongs in S Rank. Terrakion needs little to no support to pull off what it needs to do, it has all of the tools it needs.
Nominating Reuniclus for B Rank
Reuniclus has had a tough time in BW2, everyone is avoiding it because of the omnipresent Genesect, but Genesect doesn't deter it any more than Scizor used to. Trick Room Reuniclus in particular hasn't lost any of the qualities that made it so good, if anything it thrives in our Hyper Offensive Metagame. TR HP Fire Reuniclus is also one of the best Genesect lures around. Plus CM still rips apart Stall. I almost wanna say A Rank, but not quite
there. Overall: B+
I also dunno if I agree with Jolteon being B Rank. What do you guys think?
