Do you know the game Mafia? The idea of this game is the same. The only difference is the story and the roles. The role of this card is the wolfshound. He can decide, if he is a werewolf or a normal villager.
To print this, I used the multipass technique described by @makeanything in this video. So first print the color files and then the back file in black.
For all of the cards I used OpenSCAD, for this one, because it was on of the first, I used only circles, squares and polygons. But for cards I made later, I also used Inkscape and then converted the graphics to OpenSCAD.
