I had a character to submit and then my phone ate it. I will try again tomorrow, but essentially is based on Card Captors, using a magic deck of cards to perform spells and attacks. But instead of capturing loose cards, the character gains more cards by drawing and mastering its abilities based on a book given to her in a convenient plot hook. 

I'm thinking she will be fromNew York, NY but will have reason to travel to wherever she needs to for the game for, you guessed it, another convenient plot twist! :-)
