merlinBook is a tool to manage a collection of Magic Cards. You will load it with your own cards (in your preferred language). Moreover you may characterize each card by its ability saying if it's an 'attack' card, a 'prevention' card or an 'empower' card. In the settings pane you may set an URL to wich pass your card name to see other details. You may build and save your own decks and merlinBook will calculate its attack-prevent-empower status. Finally if you already have your cards list you may prepare a text file and import it in merlinBook.
This functionality requires a direct connection to Internet (3g, DSL), it doesn't work via an authenticated proxy
