"Eminent Domain" manages to be something really unique- a deck-building game that focuses how cards are used to play in a very interesting way.  Players start out with a base deck, made up of five different kinds of cards and a wild card.  Decks of those same five base cards lay on a special tile.  Throughout the game, players may play one of their cards in hand for an action, but they must select another one of the five base cards for its "role," essentially another action specific to each card, different from playing it as an action.  The player then takes the card from the tile and adds it to his discard.  Each player then may follow the role by also taking that action (though with penalties), or passing and drawing another card from their deck.
