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.
Nobody breeds anymore, i use pokemon generator-pokegen just about everyone uses it for legitimate hacks, i can probably clone my pokemon and trade you my current rain team, its modified completely off showdown and pokemon online.
gg, i would suggest zapdos, gyarados, scizor, forretress and ferrothorn as options for your team. ive made quite a good rain team with Politoad, Ferrothorn, Gyarados, Scizor, Zapdos and Dragonite
