Unfortunately you can only get it if you have the Azure Flute, an event item. If you you have it you have to go to the Spear Pillar where the Hall of Origin will be and Arceus
arceus is an event pokemon.
Pokemon Diamond, Pearl, and Platinum have Arceus.
You can only get Arceus by an Event.
You need to get the azure flute by wi fi event
