Monster Super League tasks you with catching and training unique creatures known as astromons. While the gameplay focuses on adventure and team-building, managing your resources is the best way to ensure your squad stays competitive against tougher opponents. You can bolster your inventory by keeping an eye on limited-time promotions.
