There is not a lot of terrain in that one Marvel Set. As such none of the official C3G maps only require one Marvel Set and that is it. With the likes of Superman flying 10 spaces at a time, C3G Maps are generally larger in size than that one set could make. I took a quick look at the index and Sewer Labyrinth would be the one you would most likely have the tiles for if you own any classic Heroscape sets as it only requires 1 Marvel, 1 SotM, & 1 Castle Set. The set requirements of each map are listed in the Index so if you do have more tiles at your disposal you can take a look and see what you might have the tiles for. I would check in with the
BOV map group as well and see what they have come up for using just one Marvel Set.
