The math changes of course if you already have a bunch of the tokens you'll need or a stash of bombs. Probably steep odds without spending gold.
I recommend second crafted dragons for trading. If it is a super rare you can get large gems for crafting the craftable gemstone types. It is much better than trading 10 dragons for small gems to trade for a large gem. The amount of evolution time involved is dramatic when you could be evolving dragons you intend to keep.
Otherwise, let it go and save your bombs for the next dragon. If you play long enough you will find yourself having to part with your duplicates. It is harder if they are sentimental favorites or you spend gold to get them.
