What shinies do you have, do you use them, and how did you find them?

These two are mine. I use Golduck in my Black 2 (water exclusive team, lucky me), and Spheal is still in training for my White team (ice exclusive).

Found Golduck at random while walking through a cave. The one around Humilau somewhere. Spheal I hatched while looking for a Calm one.

Golduck's meh, but he's the first shiny I've had since Crystal. Spheal is Hardy, but I think I'll stick with him anyways. Not like a change in defensive stats will help much when I'm spamming Protect and Substitute anyways.
