Lot of ideas on my mind right now but I'll start with the most interesting and unique. Maybe start with a "Rock, Paper, & Scissors" or a "TicTacToe" map, whichever is cooler, lol... no, I might make a survival map which you need to gather materials to build something, like a "campfire" for example. Also, you need to hunt food for your player not to starve to death. And while surviving, you also need to gather spell cards in order to kill other players and defend yourself to them, given that they will be gathering and using spell cards too. Something like that sort of map.
