Attach Rainbow Energy to 1 of your Pokemon. While in play, Rainbow Energy counts as every type of basic Energy but only provides 1 Energy at a time. (Doesn't count as a basic Energy card when not in play.) When you attach this card from your hand to 1 of your Pokemon, it does 10 damage to that Pokemon. (Don't apply Weakness and Resistance.)
