Can my opponent do whatever I want them to? On turn 5, I am not allowed to play any cards other than the treasures that are in my hand at the start of turn 5? Why are doctor and KC banned? Must I buy the duchy, farmland, 2-point SR and 4-point Fairgrounds on turn 5 or may some of them just be gained?
