Sorry, I was misremembering how this happened
Before the ban on Snow Warning, Snover was BL, since Hail has been banned in UU since time immemorial.
So now that the ban on Snow Warning has been lifted, there are a few places that Snover can be placed:
- Leave him in PU. He probably won't stay there for too long.
- Move him to BL2 if the RU council wants to quickban
- Move him to BL3 if the NU council wants to quickban but the RU council does not
Note that "RU" is not an option. UU, RU, NU and PU are usage-based tiers. You can't just randomly decide that a Pokemon is RU based on no usage information, nor on how well you *think* it'll do.
That's what the Borderlines are for.
Precedent: many people assumed Imposter Ditto would be a potent enough threat to be viable in OU, but no one was sure
where it would end up, so it was allowed to stay PU (from where it has failed to rise so far).
So what I'm saying is leave Snover where he is or quickban him to a BL. Calling him "RU" because that's where you think he'll end up just makes a mockery of the idea that our tiers are at all based on usage.
Edit: Okay, so the last time Snover was legal in the lower tiers (Nov. 2011), it was pulling RU-level usage, but only because Abomasnow was in UU
. And interestingly, the rise of Snover Hail in RU was an extremely recent phenomenon, as in Oct. 2011
, it was pulling NU-level usage. My point is, there's no real way to know where
Snover will end up, especially if Abomasnow reenters UU, as it is predicted to do.
