You can find it in the aqua/magma hideout. It's around the area with the 4 pokeballs altogether. 2 are elctrodes and one's a master ball.

You could try to win one in the ID lottery In Lilycove City, or get one from someone else's secret base.

Any Pokeball would work eventually, but a Master Ball would work the best. If you don't want to waste your Master Ball, I would use an Ultra Ball.
