15 Days: Mid-season

This mini-expansion for 15 Days is part of the "Achievements" series of Matchbox Collection mini-expansions, and as such should only be opened and used once the 3 criteria on its envelope have been met; because of this... SPOILER ALERT: This expansion adds a new set of Animal power cards to the base game of 15 Days, expanding the variability and replay-ability of the game.
