I disagree. If you are looking to craft dragons from the mines, you need to do a lot of evolving. Evolving fail dragons from level 3 to level 4 and then trading is much much much cheaper than selling fail dragons for 100 coins, and paying the food to get your level 6s to level 7s and level 9s to level 10s.

Fail dragons are good for evolving and getting mine bombs, and then trading for gems. Dragon Tails often requires a couple of gems to be availalbe in order to complete.
