Are there any illegal cards in here? Or any ways to improve it? I can think that Darkrai is not needed but I don't know what to switch it (and the energies) with. Preferably a Pokémon with an ability that can poison the opponents active Pokémon from the bench. Any ideas? Thanks.

Use Ninjask and Devolution Spray to put Shedinja onto the bench; then I use Gengar's Night Corridor or Ninjask's Night Slash to switch with either Shedinja or Robo Substitute. This method will slowly deal damage while your opponent takes no prizes because Mountain Ring will protect my bench, and in case I need to do more damage, I can always put up Virbank City Gym so Gengars total damage including the poison would be 120 if they don't retreat, but even if they did retreat, it would still do 90 damage which is enough to kill a 170-180 HP EX in two shots.
