Here's a team built around spdef maro-a (which beats magearna, koko, volcarona, zapdos, magnezone, ferrothorn, most medicham, most kartana, and many more esp with grassy terrain), and flying-z tornadus-t. Sub sd bulu gives heatran and maro-a grassy terrain support. Feel free to change mew's speed and sludge wave for a fighting move, that's up to your preference. Enjoy fren :]
