My EBI seems to love butterfly dragons and that's it. Got 2 in quick succession, but still having no luck with breeding any of the others I've been trying ages for: sandstorm & bluefire mainly. Also haven't had any luck with current.
Congrats! On your Butterflies dragons, as they are my fave for the momemt. As you may know, there is a slightly better chance in getting the Current in your new EBI. I got it with water + mag, but others got one with water+ firefly or scorch. This combo may give 3 hrs failed attempts, which is good or breeding with mag will give a high resale fail attempt. Good luck and keep trying. Try one way water + hybrid a few times, if you don't get it, switch the position to hybrid+water once and switch back. Something about tricking the game.

Bluefire is a straightforward combo fire + cold hybrid. This could be storm, snow or ice or lichen. Its been awhile, but any of these should work. Sandies are a different story. They are more rare than the rares. It's a air + earth hybrid, try mud or iron would be my suggestion. This one may take a while, your tenacity will be tested.
