Official Announcement
For this contest, your submission(s) you can use 1 FREE (extra) Marvel Set for building your maps.
Since the marvel set is already considered a Hybrid set (can be used as a MS or Expansion in your submission), this new rule simply allows you 1 extra Marvel set if you want to use 2 in the same map build.
Example: You build a map with BftU (MS), RttFF (Exp), Marvel (Exp), Marvel (Extra)
