Best Units to Prioritize

While building your defense, prioritize units with area-of-effect attacks for handling large waves. Sonic and Shadow are excellent early-game units with good speed stats. Don't neglect support units that can buff your other characters. Save your premium currency for limited-time units during events. A balanced team with damage dealers and support is key to clearing difficult stages.
