Ok now that Genesect is gone time to go through some Pokemon:
Skarmory
I am really torn about Skarmory right now. On the bright side, Genesect's recent banning made Skarmory much more viable, as Skarmory was pure set-up bait for RP Genesect, and in general hated Genesect. Skarmory was and still is one of the best physical walls in the game, with awesome bulk, resistances, reliable healing, Spikes and SR, and phazing (it can even use Taunt). This allows it to wall or check some prominent physical attackers such as Scarf Salamence, DD Mence locked into Outrage, any DDNite and CBNite locked into Outrage, choice Kyurem-B locked into anything bar Fusion Bolt, Scarf Terrakion, Mamoswine, physical Landorus, and Garchomp.
However, the fact that Skarmory is a purely defensive Pokemon that slows down the pace of the game does not help it in such a fast paced meta, especially when many of the special attackers that easily force it out can easily switch into it, namely Thund-T (with SR off), SubCM Jirachi, SubToxic Tentacruel, Specs Politoed, LO Latias, Rotom-W, Starmie, Magnezone, and Ninetales (with SR off). And giving a free switch in to those Pokemon is never a good thing, as most of them are quite difficult to wall, while the others are annoying to deal with due to particular reasons (Volt Switch and WoW on Rotom-W, Scald on Starmie, and SubToxic on Tenta). Also when using Skarmory, if one wants to really abuse its Spkiking ability, then he must dedicate a slot to a spin-blocker, as Skarmory is Rapid Spin bait, slowing down the team even more as more Ghosts are defensive Pokemon (except when running Gengar, but Gengar is usually seen on offensive teams, where Skarmory doesn't fit), which again is not such a good thing atm. Finally, while Skarmory certainly checks a lot of physical attackers, it cannot wall most S and A rank physical Pokemon as a whole, meaning that you cannot deal with them solely with Skarmory. For example, Skarmory can easily switch into ScarfMence and Scarf Terrakion, but not against DDMence and any other Terrakion, meaning that you must use more checks for those Pokemon. In fact Skarmory completely walls very few Pokemon in S and A rank, mainly Garchomp, who can still get past it if run on a sun team, Dragonite, and Breloom after Sleep Clause is activated. Against all other Pokemon Skarmory has to scout sets first, limiting its ability to freely switch in early game against Pokemon that it is supposed to handle, such as physical Landorus, physical Kyurem-B, and SpD Jirachi.
So even though Skarmory is still a very good poke, and it is the best all around Dragon-type counter ever if you use a SpD set in rain, it kind of struggles in this fast paced meta, or at least struggles enough to not be in A Rank. That's why i believe that Skarmory should remain in B Rank.
Breloom
Even though the banning of Genesect had little influence over Breloom, i think we should really consider putting Breloom in S Rank. Breloom's versatility, ability to sweep, and threat level were never this high. Breloom can run 4 different but all very destructive sets, namely SD, CB, SubPunch, and SpD with Leech Seed, which often have different check and counters. After sacrificing something to sleep, you bring in Latios thinking you will be able to revenge kill the SD set? Bam Breloom threatens for a 2HKO with LO Low Sweep or sets up a Sub proceeding to scout for your move and then smack you around with Focus Punch. You bring in Skarmory after Sleep Clause is activated? Bam CB Low Sweep 2HKOes with very little prior damage. But Breloom is not only versatile, it is also powerful, has Spore which often equals to a free kill, has good resistances to switch in against many defensive Pokemon, and finally has Mach Punch to serve as a very good revenge killer. It does so many things, and it does them so good, making it a huge influence in OU. I could say more but we all know how good Breloom is, and most of you have already a solid opinion about Breloom's ranking so i will stop here.
