I'm trying to make a Yu-Gi-Oh! card game with Pygame that works as a very simplified version of the video game versions (i.e. monster cards only, and they can only attack, thus for now they should only have attack points as attributes). But now I'm struggling to implement the cards' atk points as attributes for the battle system, since each card is represented by a pygame sprite taken from a list of sprites from the very same class, instead of each card being its own instance of its own class for allowing proper attribute implementation. I'm really stuck on this, so would really really appreciate any solutions. I thought about implementing each card on its own class as just mentioned, but since i wouldn't be able to know which cards have already been drawn at a given moment, i don't see how i would be able to properly filter the available cards to be drawn from the deck (the list named self.deck at card.py) at a given moment through the card list without repeating some of them that should be unavailable.
