Ok ok, to reiterate what I said, and ultimately want:
1. The only time that Basic dragon energy should be printed is when the sun physically engulfs the earth. They could prevent the sun from engulfing the earth if they got rid of an existing energy type.
2. Never ever have a Dragon energy icon near an attack, which means, no pokemon shall require a dragon energy to have an attack.
3. All Dragon type pokemon needs to have at least one attack that requires 2 different energies to use.
4. The only dragon energy card that exists is special dragon energy, who's purpose is to change the effects of an existing attack, for example, without special dragon energy attached, the attack, which requries Lightning and Psychic energy to activate, for example, makes the opponent's pokemon paralyzed, but with dragon energy, it makes it poisoned instead. Sort of like that.
It be cool to have Earth energy for ground and rock types, and Air energy for flying types, but I know that the gameplay and the amount of spending you need to make a deck would suck, and adding another official elemental type, (technically I don't consider dragon it's own element, rather it is a multi element), would destroy the game, unless boosters came with 20 cards or something, rather than 10. I don't consider multicolor gold framed magic cards to be "gold cards", but rather, multicolor cards. So I see Dragon types in the same boat as multicolor magic cards.
It's sort of like this
Red = fire
Orange = fighting
Yellow = Lightning
Green = Grass
Blue = Water
Violet = Psychic
White = Dragon
Black = Colorless
I don't mean the colors as being the color of the energy card or the frame of the cards, I am referring that the other 8 elements only allow their own element to activate, while dragons, while not having their own basic energy card, relies on at least 2 or more of the other 8 elements to activate their attack, much like if you combine all those colors, you get white, with the exception that dragons don't need every single energy card to activate an attack.
