@Swoobatman: You should check the description of the Crystal Dragon, in the Store of your game. It says, and I quote:

"If you like shiny, valuable things, you will like the Crystal Dragon. It is very rare and only shows itself when the planets are appropriately aligned. You'll be lucky to see it! Breed Pure dragons to get the Legendary ones."

For real.

No one said it would be easy.
