Not really, it outspeeds pretty much everything, sets up on whatever it wants. As such a fast subseeder, it can outsall stuff like Blissey, while grass types which resist leech seed are easily taken out by Air Slash. Scizor's Bullet Punch is a good check but loses to any Skymin with HP Fire (surprisingly common). Serene Grace and Air Slash means it can flinch through everything, and if Seed Flare gets a SpD drop, even stuff like Heatran will be flinched to death if it lacks Earth Power.In that case, is there any way I can try to argue Shaymin-S into OU? I can see a few points that could make it easily counterable, so I'd like to try and convince someone.
There's a reason it got 100% of the vote to be banned. It was stupidly overpowered - amazing stat distribution, great speed, a movepool which is just enough to let it beat anything, a fantastic signature move and one of the best abilities in the game with two STAB moves which exploit it (Seed Flare and Air Slash).
