Dominion: Cornucopia has made it’s way onto the Rio Grande Games site, with a release date listed as spring.
With a theme of variety, it looks like this will be a great expansion to get you to buy cards that you hadn’t before. This expansion will have 13 new kingdom cards and 5 unique cards. Size-wise, it looks like this expansion will be similar to Dominion: Alchemy.
