Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I run a quad weather team. Tyranitar, Abamosnow, Ninetails, Politoed, Salamence, and Dragonite. Don't judge, because it works really well. The two dragons aren't doing so well against steel types. Any suggestions on 2 pokemon that can back up my weather?
