Heros Deï is a Collectible Card Game based on different mythologies. However unlike other CCG's, in Heros Deï no card is rare. Once a mythology pack is bought, no other card from this mythology will come out. Booster contents (ordinary cards that can be multiple in a competition deck) are known when buying. As to this date (July 2005), 3 civilizations have come out: - The Celts - The Greeks - The Vikings Interactions between heroes, gods, monsters and objects are especially faithful to the original mythology, since this original game has received assistance from Britain's cultural department.
