Garchomp @ Rocky HelmetYeah Thunder Wave would be cool too as well as any entry hazard really.
I thoght about Tail Glow Mega Manectric because people usually think it is going to pivot so a Ground-type will be sent while you set up to destroy things later. Intimidate helps with priority but yeah is possibly a bad set. Maybe Raikou could work?
