I'm sorry this may seem like a dumb question. Was playing this with a friend and we came to a disagreement. He played a hero card that had a power on it. He thought you got to do that power immediately. Then still got to choose a power to use during his power phase. Is he right?
He is wrong. Playing a card just means that it is in play. In order to utilize it, you need to wait until the Power phase. During the power phase this card will be one of his options.
