Wow. I still haven't found a shiny on either my Black or White (though I have in other games; see my previous post(s) for that), no matter how much I've searched. And I'm trying to hatch a shiny Magikarp and have hatched about 60 or so eggs with no luck so far. So congrats to you on being so lucky!I have had some incredible luck with shinies in White. Firstly, I encountered a random shiny Durant while traveling through Victory Road the first time on my way to the league. Later, while on my way to capture Kyurem, I encountered a random shiny Piloswine in the grass. Lastly, I was breeding Barboach to EV train and what do you know? A shiny one hatches and even with the nature I wanted.
Thanks a lot. I do not know how I have had such incredible luck. Good luck to you.
