I added a poll at the last second just to see what people think
Well, if you have recently looked at the tier list for Smogon on the forums. The tier for Shaymin S isn't in the strategy dex, but the updated tier list was posted on Smogon forums (I found it earlier on the forums, but forgot the page) Shaymin-S is in OU. So, what do you think about it? Will it drastically change the metagame like the removal of Garchomp, or, will it just be a simple OU Pokemon, strong but counterable.
Here is Serebii's page on Shaymin: http://www.serebii.net/pokedex-dp/492.shtml
It seems that Shaymin Sky Form actually has Serene Grace. I don't know of any moves that would STRONGLY benefit from Serene Grace.
BTW: Don't say to me, SHAYMIN S ISN'T OU, HOW DO U KNOW? Because I looked at it on the forums. The reason its not on the Strategy Dex is because Smogon might not know how it will battle in the metagame until Platinum gets released in English.
