Better chance at getting shinies
Everyone should know that getting a shiny Pokemon is incredibly hard. This method makes it easier, but it is still a huge longshot. I have a garchomp from japan, and caught a ditto. Since the two are from different natuions, when they breed there will be a bigger chance I having a shiny. It is like 1/200-2500 or around there, which is a big improvement from the norm.
