Hearthpwn

Cool deck. I found it because I recently started tinkering with my own version of highlander dragon mage in the current expansion, and I wanted to see if that's a thing. Apparently not, but this deck does okay. Here's a link if interested. https://www.hearthpwn.com/decks/1313596-highlander-dragonzoth-mage It would be cool to add Chromaggus to it. Hopefully at some point in the next expansion they'll make all dragons from all expansions standard. Would make sense. 

From the failure of reintroducing broken cards like Evolve this time, I doubt if they will still try to return wild cards back to standard in the next expansion. But returning wild dragons back to standard next expansion might still be possible that it matches the flavor of it, so you can expect it to happen.
