The cards are printed by a very special method which consists assigning unique numerical values, names, and codes (for weapons) to each card type. Thanks to this, each card is unique and some of them may have a far greater value than their purchase price was.
The excitement of scratching strengthens your relationship with your cards. Scratching is fun and exciting until the end. Furthermore, this method allows players to purchase their cards little by little and thus makes the game more accessible to a greater number of people.
The game can be played in both ways. You can play both with friends at a table and online on your smartphone. The best is to combine both ways of playing (if your friends aren't nearby, you play in the app). The app also contains spells that are not in the physical version. On the other hand, the physical version lets you play advanced game modes and expansions.
