I wouldn't exactly say Heatran and Rotom-A beat it since any LO Zapdos worth it's salt should carry Roost whether they have Agility or not. If anything, SpD Heatran is at a stalemate unless it Roars and straight up loses if Zapdos is the last mon. Rotom-A eventually loses 1 on 1 whether by damage or Pressure unless it's ResTalk. Mence shouldn't even be mentioned considering it's banned, but that's a nitpick as you were just making a point. SubRoost Zapdos works "better" with support, but it doesn't exactly demand it IMO. Everything being said, though, I wouldn't actually be mad if Zapdos drops to A Rank. As good as it is, it's still one-dimensional when you talk about it offensively. It will never beat Blissey, Tyranitar, or even Snorlax. CB Scizor has always been a swiss army knife. It's a good utility Pokemon and a good pivot. CB U-turn really isn't doing that much though when the switch-in is any of Skarmory, Gyarados, Heatran(requires prediction on Scizor's end), Zapdos, Gliscor, or bulky Rotom-A. Hell even bulky Crobat, Nidoqueen, and Moltres switch into it pretty convincingly. And often times I find CB Scizor users can't abuse the momentum they get off of U-turn to take advantage of those switch-ins I mentioned. At best, they force me out for 1 turn. As far as trapping Gengar and Starmie, CB Scizor doesn't even do this well. Gengar will just Sub or force Scizor to Bullet Punch, which just turns Scizor into setup fodder after the KO. LO Starmie actually OHKOs Scizor with Hydro Pump if it happened to come in once before and took SR damage. You do trap and KO the standard spinner if they decide to switch, but they probably know that, so you'll end up taking some Surfs/Hydro Pumps before you KO them at best. Bullet Punch is it's safest move overall and it just leaves Scizor open to too many setup opportunities unless it's really late in the game. I still think SD is it's best set, but for everything Agility Zapdos can't sweep through, there are just as many things that SD Scizor can't ever hope to beat. I even think Scarf Scizor is better, but that is debatable because of less power. CB Scizor is just...too slow :/ . If we want to keep Scizor at A Rank, that's fine I guess. I just think it's terrible as an A Rank Pokemon overall. I will say this about Jolteon, though. I used to think the same thing about Wish Jolteon, that "it doesn't have time to Wish". Then I tried it. People really need to try out Wish Jolteon. It's a lot better than people give it credit for. Running Sub or Protect with it just creates more mindgames for your opponent.
