Okay, this team's defensive core is a Fire/Water/Grass one. Serperior sets up screens and taunts, Torkoal sets up Stealth Rocks and Rapid Spins, and Alomomola Toxics walls and passes Wishes for the other 2 to heal themselves. My offensive core is a Volturning one. Eviolite Magneton walls Klinklang and Swellow, while providing good offense in Volt Switch and having good synergy with Alomomola.(Have her pass her Wishes to Magneton when he gets weak) Braviary is a fast and powerful pokemon that uses his Choice Scarf to scout with Uturn and revenge kill pokemon with his Brave Bird and coverage moves. At last there is SubCM Mesprit which uses the Screens to set up a sweep when the opponent's team has been weakened. Try it out, then we can work on making your own team
Just copy and Paste that on the Import option in Teambuilder.
