This is a JS website that works as a local inventory for Magic: The Gathering cards. Currently it is built to support 4th edition only, but it can work with any edition by downloading the JSON list into the /json folder and JPGs into the img/cards folder.
Start python server inside magiclist folder:
$ cd magiclist/
$ python -m http.server
Open local collection on:
http://localhost:8000
The card IDs will be saved in a local storage cookie named collections.
