That makes sense then. And Empoleon has great defense (psh, Infernape could pwn the thing with Close Combat any day >.>), and Swampert, well... We all know it pwns (after all, it's Zuzu =D).
And I find it funny that Latias is OU while Latios is UU, I believe. I mean, you'd think Latios would be stronger because of gender discrimination and all. Then again, this might be a good thing XD
