An expansion for the hidden role Faerie game Midsummer. The Goodfellow expansion adds a new set of 18 trick cards to Midsummer, based on quotes from 'that shrewd and knavish sprite call'd Robin Goodfellow.' These new cards can be used instead of the original cards, shuffled into together or both decks can be played alongside each other for twice the trickery. A new concept of cards that are kept for ongoing effects or until their effect is spent are introduced, adding additional depth and options to the game of intrigue and favours.
