I have never really had any luck with shinies... EVER... I have found a total or THREE in my life. The first one I got was in emerald, and technically, it's the best possible shiny you can get: Nincada. Because, well, now I get two shinies out of the deal! :) (I haven't evolved it yet; let's hope I don't screw it up and just get one!) Next, I played through X and Y FULLY without ever seeing one. My brother, who is obsessed with the Masuda Method (even though it has never worked for him...Poor guy) finally convinced me to try it out. So, I started breeding Minuns. Three boxes later, POOF! SHINY!!!!! *Commence freakout* My brother, who was on box ten of his Treeckos, gave up after that. xD Finally, months later, I was in the car looking for a Magmar in the FriendS. I got an encouter, and I LITERALLY thought to myself: What are the odds of it being shiny... Well, I guess it IS technically possible... POOF! SHINY LAMPENT!!!!! WOOOHOOOO!!!!
Okay, I'm done. :D
