Deal out 6 cards to each person.  Have someone start by offering a prompt, such as a method (along with a short explanation of the method if others are not familiar with it) or a group dynamics dilemma.  Each listener picks out one card from their hand that they think is most relevant and offers it in response.  The prompter reviews the cards—this is most fun when accompanied by lobbying from each participant as to why their card is the most relevant.  The prompter selects one card as the best fit, and whoever's card was chosen receives one point.  Discard all the cards that weren't chosen, and deal out a new card to each person so everyone once again has 6 cards.  Take turns in a circle until each person has had a turn being the prompter and judge, or until you run out of new cards.
