In Fort Stars there are 8 Leagues, these are accessed by reaching the required Medal score which is obtained by winning or losing matches. When you enter a League new cards will become available to you and the higher you are positioned in the League the better the rewards will be that you can earn. To determine what League you are in you simply have to view your Player Profile which will show the League badge for your current League.
