well, according to my tool you ahve about a 2% chance of getting an ultra-rare dragon. What you might want to aim for is either:

- least amount of possible offspring

- least amount of average fail rate

- least amount of weighted average fail rate

- least amount of loss income

For the least coin loss, check the Diamond Dragon  for the other three option you might visit my tool: http://dragon.sjau.ch --> Diamond tab
