Backflip Studios tries to stay away from putting limited dragons into the breeding combos.

There are only a few dragons which require a limited dragon to be bred and in the case of Moonstruck both dragons were available at the time to breed. Ovalith is a bit trickier, but since the combo was found out during Bring 'Em Back I suppose both of those were available too at the time.
