I made a free print & play dueling game that you can play using any deck of cards
Circle of Power is a free mecha-themed dueling game for 2 players. Just print out Fighter sheets for 2 players, and give each player any 40-60 card deck (like a Poker deck, or even a Yugioh deck or a Magic deck) and some dice, and you're ready to play.
Each Fighter has various Parts that they can activate. Attach cards to Parts to Charge them up. Once they’re ready to go, Discharge them to unleash their effects, allowing you to do things like attack your opponent or disrupt their card economy. Discharging also generates Gauge, which you can later spend to activate more powerful effects. Reduce your opponent’s life to 0 to win the game!
