I know that there has been complaints about other cards being overpowered, but after playing a few games with my sister, who had never played before, she won almost every game by strategically using the play all card.
Her strategy was to remove the hand limit, increase the draw limit and decrease the play limit so that she could keep her cards in her hand. She would then wait until she got the play all card and a goal that matched two of the keepers in her hand. Then she would win the game by playing the play all rule and then playing only the cards she needed to win.
I thought that perhaps the rules required for all cards to be played first and then determine if she had won, but she reminded me that I had told her "The game ends when the current goal conditions are met".
So what's the actual verdict on this situation?
