On my android tablet I have much better luck obtaining rarer dragons than on my ipod. Yesterday I bred the moon dragon, and today I bred the diamond dragon using firestorm and island. I don't know if the levels matter but they are both level 9. I've been trying to keep track of my breeding pairs, but I never have the same results on my iPod. The iPod is so much better too because you can trade and place dragons in the stable and craft others, but my android game is far easier. I won't give up though. I want a unicorn dragon. I'm going for virtue next
