Is it possible to edit each card? I have a stylized card for each, but I don't know if it's possible.

Yes, it is possible to edit each card. This is done via Skill Notetags which can be used to specify the card's Visuals (Base and Art), Passives and Actions.

 You can find a full list of the Skill Notetags on our Plugin Wiki: https://card-game-combat-help.alwaysdata.net/doku.php?id=start

You can learn more about how to set them up in our Tutorial Video Series: https://youtube.com/playlist?list=PLrWrrMilo4zpEMix57yw7qxViPTPaGK1r&si=bXSlzy4O...

We also recommend you ask these questions in the appropriate stickied thread instead of creating entirely new ones:
