Well, looking at your team, I note special attackers in Jolteon and Keldeo, walls/utility Pokémon (AKA Drizzle) in Ferrothorn and Politoed, and Toxicroak as your only physical attacker. Salamence is the physical one of the two. Not sure if it's the better choice (Latios does get Soul Dew...) but that's my opinion. --- For those of you starting topics about the PS4, there's a PS4 board: http://www.gamefaqs.com/boards/691087-playstation-4
Kingdra. The answer is Kingdra. Rain Team + Dragon = Kingdra.
You probably didn't see his post, but it's Smogon rules. So no (Swift Swim) Kingdra w/Drizzle Politoed. --- For those of you starting topics about the PS4, there's a PS4 board: http://www.gamefaqs.com/boards/691087-playstation-4
