How do you get a pokemon by breeding with the nature that you want in pokemon platinum?

This is an older trick now, but it still works. Give the parent with the nature that you want an Everstone. This stone increases the chances of the parent passing on its nature. Be aware that it could still take a while to get the right nature, even with this item.
