not on strategy. you start by choosing a card (you don't know what's on the card before choosing it) and then you see if you got attack of defense. if you have attack, you start the fight by attacking (this is best). if you have defense (bad luck), the enemy starts the fight. then, your weapon/shield has 3 attacks, rock, paper or scissor. if you pick paper and the enemy picks rock, your attack will work fine. if you pick paper and the enemy picks scissor, your attack will fail. and you don't know what the enemy will choose before choosing yours ! a fight based only on luck.. no..
