Alright, here's the deal. My little brother wants to fight me in a triple battle.

I gave him some advantages. I cant switch out (regularly, voltswitch and such is fair game), he can use legendaries and I cant. (Pretty sure he's going to use Arceus and maybe a perish song combo)

Under these conditions, what team should I build? I'm debating on using a Ghost team to have fun with it, but I'm open for suggestions since I barely play triples.
