I have asked on Ask the Masters but saw was suggested to someone else to discuss it here. I am confused by the ruling on Dawn Stadium. There are other things that look at something and will happen such as Houndooms' Black Fire attack. Dawn Stadium has on it "for each energy card attached remove 1 damage counter" and the ruling say "Whenever" means that it would only look once per effect for if an energy is attached. If that is true then why would there need to be the word "card" even on the text with any attachment only healing 1 damage counter. I would think with the word "card" being part of the text that the stadium would be looking to see how many energy cards were attached for any action. I don't know where to find the ruling that would state why Dawn Stadium would see that an energy card was attached and not look to see if more was attached since it looks for energy cards and not energy. Would this work different with MD Manaphy since it has a body that uses "when" and not "whenever"? There has been many discussions since D&P sets because of the use of the word "card" and not using it that I am truly confused and wonder where I find out how things work.
