You can try Snorlax+Weezing if you want, nothing is stopping anyone. For a brief reminder: the only reason, by the very definition of how tiers are built, that Lax is not OU is because not many people are using it, since OU is based on usage. Nobody will have been wrong about Lax being not OU if a lot of people suddenly start using it — that's not how tiers work. We thought the same thing would be true of Skarmory what with the attack split, and Gyarados/Garchomp/Infernape etc, but now most of the more observant and experienced of our players will agree that if Skarmory wasn't OU in the late spring and early summer, it sure is now.
All tier talk does, though, come with the disclaimer that even "good" people can't really tell what's OU because nobody is "good" enough to be watching literally every battle and logging usage. I reiterate, OU is based on the quantitative usage, not futilely qualitative assumptions of what pokemon are good and therefore probably used a lot. A comprehensive logging system is still not available to us, and likely won't be until competitor is out, and it's really simple that this is why i banned tier talk until the community has had something like that in place for months.
