Focus on the enemy fort first, then the heroes. Select the proper order when your heroes. Soften up an enemy before finishing it off with a more powerful attack from a different hero. Begin taking out enemy heroes with your front line, then attack the fort with the rear line. Reposition them to get the bonuses. Have a full row of heroes deployed to attack the fort easier and destroy enemy heroes. Do not allow your opponent to have larger numbers. Limit their heroes to two or three heroes per turn. The more heroes you have active, the more damage you will deal. If you fill the board, swap lower power heroes with better ones.
