Dominion Cornucopia and Guilds
This combines Cornucopia and Guilds in one large box and adds 13 new Kingdom cards to the game. This expansion has coin tokens that you can save to spend later and cards you can get more out of by paying extra for them. It adds 13 new Kingdom cards to Dominion, plus five unique cards. The central theme is variety; there are cards that reward you for having a variety of cards in your deck, in your hand and in play, as well cards that help you get that variety.
