DC Comics Deck-Building Game | Cryptozoic Entertainment - This past year we discovered a new style of card game. "Deck Building" games. They are fast set up, and the games play with a lot of variety. You start with a small basic deck of cards and spend points to buy new cards to add to your deck and gain victory points. Very enjoyable. Cryptozoic also has two Deck Building Card games based on the Lord of The Rings that follow the same basic mechanics with a Tolkien setting and flavor.
