Sometimes different is better going to keep this short because I am tired (please excuse my lack of professionalism). First, I want to build a team around curse rest pert so the first partner is talonflame to get rid of all the pesky grass type. Next is gourgeist to complete the FWG core and a way to not get 6-0 by sand drill. Next is special defensive drill for a latios and fairy switch in with rocks and spin. Next is orb water horse with rest talk because it is my only dark answer. Finally, thundurus for either priority t-wave or nasty plot to make the team even more offensive.
