It will be easier for you to get Legendary Dragons if the dragons you are breeding are at a higher level -- but even then it's luck.

Level up your Rare Hybrids to 20 if you can. They are also useful for battles, and the higher the level, the easier to win the battles. Also the higher their levels, the more gold they produce.
