This depends a lot on how many farms, nests, evo temples and breeding dens you have. If you have the maximum each and run them full tilt, it works without paying gold. I managed with 4 nests, 2 evos, 1 breeding den, to reach the last dragon with 12 hours to spare; also I didn’t manage to breed Darkstone, so I crafted it around day 4.

If you miss some facilities, it’s gonna be tough. Bingo boosts can help a bit, but this in turn might mean that you have ro plant unfavorable food or breed dragons that are not what you need.
