In response to the actual thread question, a pure elemental dragon is read as a pure and its alt element during breeding. This, I believe, increases the chance of getting a hybrid of the alt element and whatever element(s) the other dragon is. It should also increase the chances of getting another pure elemental. Just know that the pure element is a wildcard in breeding, meaning it could take the place of any element in breeding, which highly increases the chances of getting an elemental, or (rare) hybrid as well.
