I want my team to be heavy on Df and Sp. Df, yet still have alright At and Sp. Attack. I'm doing alright so far, but any tips? I know to use Training Bags, fight Pokemon with heavy Df stats such as Roggenrola, stuff like that. (Although I'm not familiar with Gen VI.) I want tips that are new to X and Y.
