Trick Hire More Unit
Hire 2 unit in the capital side. Remember, your group must be in the city. Then, drag the 1st unit to your 2nd unit. These 2 units will be moving into your group! You can use this trick to your CITY GUARDIAN. But, don't hire up in 13 unit, because it makes your unit take the enemy side and enemy will move to the corner (BUG).
