I’ve made an interactive PDF for stat cards for Deathball. Dropdowns allow selection of position and team trait. The back of the card allows an image to be inserted so you can either do a team logo or picture of the model. The cards are designed to print at 2.5"x3.5" so should fit standard card sleeves.
