The Apprentice account is our free account and gives you a chance to try out CardCastle before deciding to pay.
As an Apprentice, you can add unlimited cards to your collection, create a single deck, add up to ten tags to your cards and get real-time card prices. However, you are limited to browsing the first 100 cards added to your collection
The Guildmage account is our paid, full access account.
As a Guildmage, you are free to browse your entire collection, create as many decks as you want, track the value of your entire collection, in addition to everything an Apprentice account can do. Guildmages also get access to all the exciting new features as they are released!
