Residuel is a 30 minute 1v1 card duel game with a unique mechanic that places importance on adaptive strategies rather than pre-planned ones. Cards are played for effects that complement each other, however each card you play provides your opponent with materials from which they can create Servants that will punish you until you are able to destroy them. You must consider whether you'll be able to deal with the creatures your opponent might create using the resources you played cards provide them with. The player best able to set-up and knock-down the constructs of their enemy will assume the role of create, their enemy fading into history as but another trial overcome. —description from the designer
