Battle System
Match cards by pairing face-up cards in your hand with cards on the field, similar to the memory game concentration
Matching cards = playing cards (equivalent to the card-playing action in typical card games)
Your turn ends after 3 failed matching attempts
With good luck and memory, you can take multiple actions per turn
You take damage each time you fail to match cards
Some cards have effects just by being placed on the field, or activate effects without needing to be matched
Turn-based system where you and the enemy alternate actions
Reduce the enemy's HP to 0 before you are defeated
