The Pups Promo Pack includes 5 new cards: the Legendary Pups and the Underdog card, which can be added to any game of Pups for a new play experience! The 4 Legendary Pups are: Cerberus, Argos, Laika and Saurr, and they respectively take the highest seat of power in each suit. The Underdog acts as a special catch-up card awarded in each hand to the player with the fewest points. Each Pups Promo Pack also includes a rules card.
