So what of the folowing: The attack is designed to do damage but you flip tails and end up with zero damage? The card text would have me believe that the attack would still get the +10 from the darkness energy card but the rulling says otherwise. A pokemon power on the defending pokemon reduces the attack to zero? Is the +10 then lost even though its addition would be sufficient to get past the barrier pokemon power. Resistance reduces the attack to zero. So again the +10 from the card is no longer added? All of these hinge around the fact that you can start with a card that could do potential damage, flips may reduce that to zero (initial damage???) and then powers or resistance could reduce the actual damage to zero. Actually doing damage is quite different to having an attack that can potentially do damage.
