Whenever a new set comes out with new theme decks, I always check the rule book to see if there are any changes or adjustments. I just checked a team aqua them deck rule book and thought I saw a line in there saying that all types of energy (including metal and dark) can provide colorless energy. The text on the newest dark energy states that it provides dark energy. (same with the latest metal) Which is it? Can dark/metal provide colorless?
