Been MMing for a shiny Zorua as of late. So far, have about six boxes (haven't been keeping perfect track of the egg count) and no luck. Of course, that's approximately 200 eggs or so, so I'm not very surprised that I haven't encountered one yet.
On another note, I just caught a random-encounter shiny Swanna on Marvelous Bridge, making it my third RE shiny. I seem to have more luck finding shinies via RE than I do MMing XD
