dusknoir if your opponent has more the 4 bench pokemon
ampharos to spread damage the new one by the way in platnuim
diagla G Lv.x

it really depends on what u want to do>
all I see in my area is weaville + special and perhaps a few non special darks. It lets you set up GG by turn two (providing you rare candy to weaville turn 1), adds extra damage, and speeds the deck up. Psy locking every turn is still a very strong strategy
