the whole purpose of this thing is not to "post a snapshot of 2003." the point is to try and combine what we know now about GSC while still reflecting its history. for example, I've been editing a lot of GSC pokemon analyses because they're just out of date; many haven't been changed since they were originally written--5, or even 6, years ago--but I wouldn't change Tyranitar's analysis and say that the TB/DP/Crunch/Pursuit set "is Tyranitar's standard moveset" just because it's been popular recently.
I just want to get things right. Jumpluff is just not OU, for example; I don't think Jynx is either. but I also don't think Lanturn is BL, and I'm actually surprised that people have actually cared enough about this to post. As you said Charlie Brown, there were no efforts to regulate UU play in 8 years; I honestly just think that if no real effort has been made to regulate it in 8 years, why start when, IN MY OPINION MIND YOU, GSC has been reduced to basically pure theorymon since no one plays it anymore? I still haven't had any more people who actually play come and protest based on their actual experience. I see that you're saying "since we're already practicing theorymon, we should take it to the next logical step and try," but our theorymon has been limited to the OU metagame that we've played forever, not the UU metagame that, I still contend, has never existed.
I don't think there could be a more ignorant argument. "This hasn't existed, therefore it never will exist". In fact, I'd argue it HAS existed and it ALWAYS will exist. People had UU teams, therefore, by definition, UU play existed.
first off, I don't enjoy being talked to condescendingly; though I don't agree with some of the things you've said, I certainly wouldn't call it, or you, stupid.
second off, people had UU teams, but they were mostly made with standard play in mind. people could play UU x UU, sure, but when these teams were made, I don't think the people made them with "I'll never have to worry about countering Snorlax because he's overused," etc. I never did, I distinctly remember a UU team I made with such facemelters as Raticate, Hitmonchan (who is awesome), Lickitung, and Gligar, but if a UU team wasn't able to take on standards (mine could), it wasn't a good UU team.
I'll revert some of my changes since I understand what everyone is saying, but I will say a couple of things:
Chansey can switch in fairly easily to Typhlosion, it has plenty more trouble against Magmar and Arcanine.
Bellossom's stats are pretty comparable to Meganium's, plus it gets Sleep Powder and Stun Spore, which Meganium does NOT. it can't use Reflect+Leech Seed like Meganium, but it can paralyze/sleep something.
I have used Dodrio on the same team as Ursaring, and I think it holds its own just fine.
Growth Venusaur is pretty awesome when the Fire types are out the way.
Tauros is a beast, but Aerodactyl is a good counter for it in UU. does that make Tauros UU?
EDIT: as per Tauros being UU, probably not.
changes made again, check OP.
