To update from my last post in this thread: Yes. I have way too many now. Now with ORAS shiny hunting being so easy, I have boxes and boxes of shinies. O_O

Also for anyone who doesn't know about shiny values: reddit.com/r/SVexchange

Basically you find your secret shiny ID for your game (with Keysav, someone on the subreddit can help you), and people give away eggs in bulk (generally competitive Pokemon). If the egg matches your shiny ID, it'll hatch shiny in your game. So EZ.
Way better than Masuda Methoding to death.
