You need a cheat device then enter a warp code to Birth Island then figure out a triangle puzzle and boom he appears and battles you, you might want to save before you battle him.
Get an Aurora ticket from a nintendo event OUTSIDE THE GAME then use it to get to Birth Island.
Go to a Nintendo Event, such as Pokemon Rocks America, or use a GameShark or Action Replay
