Get a misdrevious in enterna forest,if you want mismagious use a dusk stone on misdreavious.
You cant in the wild but i think you can get a misdreavus in the lost tower after 8:00pm and evolve it.
you have to trade it from pearl
Only in Pokemon pearl eterna forest- night, lost tower- night otherwise you'll have to trade
Eterna Forest (Only at night)
you either get it around 23 or use a dusk stone.
Go to Eterna Forest at night. Only available on Pokemon Pearl.

Young couple Mike and Nat in the lost tower (route 209, just south of solaceon town) have a level 23 murkrow and a level 23 misdrevious. You'll win 2944 cash from them. I'm not sure what floor out of the lost tower they're on. Sorry. Search the five floors until you find a young couple on a date. Challenge them. (No idea why they're having a date in that graveyard) Hope this helped.
It evolves into Mismagius. you have to have a dusk stone. so that means you can only evolve Misdreavus in Diamond or Pearl
