Eggs of Mystery

Eggs of Mystery are special dragon eggs that will instantly change into a random dragon egg when obtained.

The resulting dragons normally follow these guides:
 * The dragon fits the scope of the mystery egg
 * The dragon can be a limited dragon, even when it is not available normally
 * The egg cannot be a Mythic or Legendary dragon
 * The egg will not hatch into any of the newest dragons (with one exception)
 * If the dragon is not owned or only twins are owned, the dragon will not be a twin
 * If a non-twin of the dragon is owned, the dragon will be a twin (unless it is a Rift unique, then it will never be a twin)
 * If multiple Rift traits are available on the dragon, the dragon may or may not receive a random trait
 * Traits can be the same as previously unlocked traits, even if some are still locked
 * This stacks with twin status, allowing dragons to be both twins and traited
 * Unless all suitable dragons are owned, the first egg will almost always be an unowned dragon

Once any Egg of Mystery is used, it cannot be traded back for another dragon.
