I thought I'd bring this up. Well, when Heroics are banned in an arena and the rules aren't restrictive to a single element, what dragons do you use? Wind? Pure? Legend? Primal?
I use Mighty Dragon most of the time, as he is one of my best Dragons and he is reliable and strong. Infinity and Hell Twin are useful in fights, and despite being epic, Tempura is useful sometimes. I'm in Master Light I and I use Bear, Infinty and Beach, who are all decent.
