You can craft a pure diamond dragon now! That's amazing!! I kinda wish I'd had that option a few years ago... but it'll be a lot of work to get the needed tickets.
New dragons are:
Neo Diamond, 125 tickets, egg: 28 hours, type:diamond
Ancient Star Dragon, 160 tickets, egg:20 hours, type: black, pyramid, cosmic
Neo Rainbow Dragon, 110 tickets, egg: 15 hours, type: rainbow
Neo black dragon, 95 tickets, egg:5 hours, type: black
Each takes 30 seconds to craft.
