User blog comment:CoolM.E/A special way of breeding/@comment-24888921-20140501160620

I was getting frustrated when breeding because all I was getting were the metal dragons. I made a spread sheet and started ti list everyone that is over level 15 and then watch your elements - try to pick dragons that dont match. I have been having great success in getting the better/hybrids. Currently I have 90 dragons and more than 30 are over level 15 you have to stick with it and if you can afford the booster for 5 gems it helps too,
