Do you know the game Mafia? This game is similiar, but it has more roles and the story is different. This role, the Great Wolf, can transform one other player to a werewolf one time in the game.
I printed this with the technique devin montes described in this video, so first print the color files and then the back file in black.
To design this, I used OpenSCAD. For this one I used only circles and a polygon for the werewolf head, but for other cards I made later, I also designed the motives in Inkscape and then converted them to OpenSCAD.
