La Baraja Mutante

In a remote place there is a Pyramid that hides in its interior a Dazzling Treasure. Four Peoples embarked, a long time ago, on their search. The People of the Valley, the People of the Forest, the People of the Mountain, and the People of Space. Four lonely heroes, bored of being so lonely, decided to join the quest: the skeleton, the robot, the barbarian and the mermaid.
Thus was born the authentic and original... Mutant Deck I
