>>49149937You don't bring Quagsire in on special attackers anyways. Quagsire's special defense is too low to justify it. It can wall just about any physical sweeper, though.
>>49149397Tiers are usage based. If you meet the 4.51% usage rate required to be in a tier, you're in the highest tier you meet the requirement in. If Quagsire had 10% usage in PU, RU, UU, OU, and Ubers, it would go to OU since Ubers isn't an official tier.
This is how sometimes Pokemon like Quagsire, Jellicent, the Slow-twins (now quadruplets), Ditto, and Gastrodon can end up jumping several tiers. If a Pokemon has a really powerful, specific niche, it can end up hitting usage rate requirements to jump several tiers. Ditto, for example, runs roughshod over metas with a lot of set up sweepers. Ditto is practically a hard counter to Pokemon like Gyarados. Lower tiers, however, tend to not have metas defined by a bunch of setup sweepers, so Ditto pretty much only ever sees limited usage in OU/Ubers and sleeps in the bottom tiers elsewise.
