I know this sounds probably silly of me...but I'd rather speed breed than buy a dragon, because you can get another dragon you don't have that way. I don't consider those fails, if that makes sense. The only dragon I've bought out of the market for gold was my sterling silver. Example: I didn't get the tinkerer dragon, but I got a beaded and a peacock, didn't have either.
Grats on all those getting this one so far! I switched over to breeding prism and water...I did get a 20 hour timer, but it could be the dreaded...or a hot chocolate or turquoise, and I don't have either of those.
