If I have a question about this game, the Compendium usually sets me straight, but they haven't updated their Q&A section with Mysterious Treasures-era inquiries yet and when I was looking at Azelf today, a question came to me. Does its Power, Downer Material, cause Pokemon such as Budew that have attacks costing no energy to cost 1 energy instead? Or does the text "the attack cost...is 1 C more" imply that to be affected by Downer Material, the Basic Pokemon has to be using an attack that costs at least 1 C to begin with?
