It occurred to me as well to make a pure first element Dragon with a Legend attack, but as far as I know there is none in the game at all. Maybe I'm wrong since I only took a quick look?
This Dragon would easily be the strongest in the game, assuming it had a decent trainable Legend attack like Legend Spell or Aurora Borealis. Then you have Sea that can critically hit three elements, and war attacks that are some of the strongest. The Dragon would destroy everything. It would almost be unfair.
Then again the only way to make a Dragon stronger than High Entity is to do a Heroic with first pure and a strong legend attack. The war and sea attacks might be overkill.
