About Castle War Cards

Castle War Cards wages its two-player siege through deck decisions: each round's card choice attacks the enemy castle physically and magically, and the first fortress reduced to rubble ends the war. Draw wisely; masonry is watching.The card economy is the strategy's whole grammar — offense, defense and resource cards contesting priorities every round, with the right-card judgment the game names as its core skill. Castle health converts decisions into visible consequence.The two-player format stages the format's proper duel: alternating draws, collapsing battlements and a war whose every escalation both players authored. Cards as siege engines — the genre's cleverest artillery.
