Shadows: Heroes and Monsters | A "Cooperative" Card Game | Review

About Shadows: Heroes & Monsters, from BoardGameGeek:

The Cave of Ederoth is home to the most dangerous monsters and dragons anyone has ever seen. But with such danger, the rewards must be even greater! Rumors have spread of artifacts and gold in vast quantities, and mysterious stones that possess unlimited energy: Shadow Stones. The kingdoms of many different realms have sent their best champions to claim the wealth of Ederoth for their own, but only one may emerge victorious. Shadows: Heroes & Monsters is a competitive Hybrid Collectible Card Game for two to three players, set in a fantasy world where a portal brings together different ages, technologies, items, magic, and species in a fierce battle for riches and glory! Each player takes control of a hero, each with their own agendas, to hunt monsters and battle other player's heroes. If a player plays their cards well, their hero will gain experience and gold, empowering their own abilities and earn more of the powerful Shadow Stones. Whoever earns the most Stones wins! -description from the publisher
