Correct me if I'm wrong, but just an interesting trivia(l) fact:
This card is the creature card with the most drastic changes in attack stats after upgrading it.
When I looked at the unupped 9 damage, and then the upped 13 damage, I was like, holy LAWD! Phase Recluse does 3 more than Spider, and Elite Charger does 3 more than Charger, but I think this holds the record, with 4.
That was random. Anyways, this is actually one of the best dragons in the game. Like every one of them except Colossal.
