This is a module for the Unplayable cube. The Unplayable cube is designed as a modular draft experience where the players choose which packages to add to the base cube.
We considered adding stickers to the main cube. While many of the designs were parasitic, just as many worked fine by themselves. However, we decided to make a module for them for two reasons. The first is that many sticker cards are black bordered. Not only is this esthetically displeasing, it also means many of the designs are generally tame. The second is that the stickers introduce a whole other set of items for players (and us) to keep track off. If only a few of the sticker cards make it into the base cube than keeping all the sticker sheets is not worth it.
The cards labeled with attractions only are both sticker and attraction cards and so are to be played when you have added both the sticker and attraction modules.
