The one I'm useing now is my favorite because if I don't like something with it I change it. (I didn't put the name since it is made by me so nobody will reconize it)
I have the darkrai lvl x and i think you could mix it with the weavile that turns pokemon into dark type and moonlight stadium to make say an empoleon have 0 retreat cost and do 10 extra damage per dark energy. (you could always make another lvl x dark type)
does intimidating armor affect...
