So, it's a mahou shoujo version of the classic card game of Battle. A game that's known for often dragging on, and for being completely based on luck and devoid of strategy. Or so I thought until the second game began. OK, it's still not very tactical. The abilities you get make your victory almost statistically guaranteed. I'm just imagining what would happen if your opponent also had special abilities, and maybe a hand of ability cards... This is so close to being its own card battle game.
But the mediocre gameplay is not why I like this game. It's the cards. All the face cards have their own unique magical girl designs, which are all beautiful and somehow still very cardlike. The two girls that are playing are in fact a pair of Jacks from the deck they are playing with! This is such a cool concept, you could do a lot with the 16 total characters you have, while exploring the dynamic of them being cards at the same time. You even have them in a hierarchy already. I seriously hope you make some games, write some stories, do anything with these characters.
I really like this entry, to be honest mostly for the potential in the ideas and designs, but nevertheless I think you've done something really special.
