Attacks » Diffuse Reflection | Energy » Reversal Energy
How much damage does Diancie's "Diffuse Reflection" attack do if I also have an evolved Pokemon with a Reversal Energy providing three energy?
The damage is calculated based on the number of Special Energy CARDS, not the amount of energy the card provides. So in your example it would only do +40 damage for Reversal Energy, not +120.

How many energy does Reversal Energy provide when its effect is not triggered? There are 3 energy symbols at the top of the card.
The single colorless energy symbol in the statement, "As long as this card is attached to a Pokemon it provides {C} energy" indicates the number of energy it provides when its effect is not triggered.
