This is fantastic. I've been hoping for a card battle simulator for RPGMZ for a while now. I always found side-view battles underwhelming and front-view battles in need of something to more fully engage the player outside of 'I click skill and do the number damage'. Having the player needing to draw into those attacks and manipulate the likelihood of getting them solves this.
I do hope to see party battles and deckbuilding in the future. I think each character having their own deck would be a welcome addition, as I do like the idea of restricting cards to character classes.
But, really, the potential here for fun combat is huge. Having enemies curse the player by adding debuff cards to their deck, resource management in the form of card costs, etc.
Really great work, to everyone who made this.
