Take turns alternately where you can play cards, initiate attacks, and activate hero powers.
Any unused mana at the end of your turn is forfeited.
Combat:
Both minions and heroes can attack once each turn. Minions generally need to wait a turn after being played before they can attack, unless they have abilities like "Charge" or "Rush."
Players must decide whether to attack the opponent's hero directly or engage their minions.
