Each unit has a different move speed, health, and attack type. Learn how they function in order to synergize your units with each other. Before starting a match, you can purchase one of the three special units to bring with you for 30 gold. Consider purchasing one if it will work well with your strategy. The Colossus is a slow giant with lots of health. Although it does not attack very quickly, if it enters an enemy base it will do a lot of damage. The Legion is a small army. Deploying it will send out a legion troop on all three lanes, regardless of where the initial unit was positioned. Use this when split pushing. The Mana Sting is a mana-infused scorpion. It functions as a melee unit, however when it attacks it will generate mana.
