The Siege

Help the King and the Queen survive the Siege until their faraway army comes back at turn 9. The two regnants command three counselors: the Carpenter, the Commander, and the Wizard, that give you options to fight back the attackers in the form of cards. Each regnant is limited to summon a single counselor per turn and play a single card, so you have to choose wisely. 

Turn after turn, your resources, and so your options, become fewer and fewer as the attackers damage your walls and buildings...
