Crossfiyah, I see Steelix whenever I NB.
Here are my comments on this:
Blaziken should go to BL. I only see it as an EndRevver or as a fanboy Pokemon nowadays, and with the announced extinction of SkarmBliss, I don't see anyone would use my favorite Pokemon anymore. I've never seen the mixed sweeper set used before by anyone either.
Exeggutor needs to go to BL as well - if not lower. I've seen this thing like ten times in my life on NB, and like half those times were because I was battling some Brazilian.
Forretress is a bit debatable. I've only seen it used by a few people, who lay Spikes and boom each and every time.
Magneton I understand is a bit debatable too. With so many more people using Sub + Roar Skarm, I don't ever see this thing nowadays.
Armaldo is becoming more and more common, which is the only reason why I think it needs a move up to OU. I personally haven't ever used it so I know nothing about it.
Speaking of stuff that's getting more and more common, Cloyster needs a move up as well. On the contrary, I never see Jynx or Jumpluff used. I've even seen more UU Pokemon on some OU teams than I've seen of either Jynx or Jumpluff.
I'm not sure what I'm feeling about Pinsir. It's a total monster in UU, and just about every UU player I've ever battled uses it, but if it was upgraded to BL, not too many people would use it after that because Heracross is already superior in OU.
Before you go after me, please consider who's saying this. ;]
