I feel like I have mad this argument too many times now but once again, Charizard Y is amazing in the meta right now, the use of really passive mons like chansey which gave it trouble are way down and the only defensive mon that really gives it any trouble right now is heatran, which charizard's partner in crime, keldeo walks all over. It demolishes defensive mons like ferrothorn, Landorus T, Gliscor, slowbro, venusaur, you name it. It also beats a ton of top tier pokemon 1v1, has insane power from fire blast which is easy to spam. It has solid bulk, reliable recovery etc etc. Also people need to stop saying that the fact that it needs support is so limiting. Sure it needs a spinner/defogging which every team packs anyway and a pursuit trapper is nice but the best part is that it gets this support from great mons like keldeo, the lati twins, t tar, bisharp and excadrill (they are all A rank or above), all of whom are easy to fit on teams with zard Y and work great with it. It's not like using zard y forces you to use a bunch of niche garbage in order to support it. Anyway about the ranks, while it is amazing, its average speed, unimpressive physical bulk and SR weakness are enough to keep it from S rank but there is no way it should drop from A+. It is simply too good right now.
