^ But it's outclassed by so many Pokemon, even in the rain. Not that it won't be seen every once in a while in Ubers, but it lacks the movepool and survivability that many (if not, all) Ubers have.
Like I said earlier, UU/BL at worst, OU at best. 'Nuff said.
Ubers isn't about how good a pokemon is there it's a ban list not an actual defined tier of pokemon like OU is. Shaymin-S doesn't have survivability but guess what it's uber. What really outclasses it in the rain? Not many pokemon have its coverage and speed but together combined with raw power. 'Nuff said.
