My friend and I started playing around with some of our old pokemon cards and we need help with the answer to a question about double colorless energy. I have searched everywhere I could think of on the web but there is no where that states in plain English the answer. Can you use double colorless energy to count for any specific energy? For example if you played a Crobat and wanted to use Cross Attack could you play the double colorless and have it count for the two energies? I did not think you could but my friend begged to differ. Is there anywhere in the rules that would say it so I could show him? Thank you for your help.
