This app allows a user to create their own MtG decks ("theorycraft") based on cards from their chosen colletion of cards. Currently one core set may be chosen to populate a collection.

Any visitor may view all of the decks created with the app. Any registered user may add a collection, view all decks, comment on any deck, and create/edit/delete their own decks.

This app draws all card information from the Magic: The Gathering API.
