Though the chance is low, but it'll better than buy them in Black Market. I mean you must pay at least 70 Gems in Black Market (if you're luck), and the worse you might even lost more than 100 Gems.

By the way, the rarity for Special Dragon is pretty higher than Gem, so if they replace the second Special Dragon in Gem card, don't try to get both, because you might end up spend 200 Gem for 3-4 Ghost, no Aztec.
