You mean Treasure Energy? It's Dream Ball and Treasure Energy, perfectly understandable mix-up lol. I for one was not particularly keen on the prospect of a new Dragon Energy, probably because I feel like there's a ludicrous amount of special energies in standard already, also, the most recent ones, Spiral and Impact haven't been particularly interesting. And dragons not having weaknesses is already good enough that the least they should have to do is work to fulfil their silly attack costs. Double Dragon reprint would be the silliest and most lazy outcome of all, thankfully I'm almost 100% positive it won't happen.
