When creating your star realm, be ready for the unexpected. The rules of conquest and commerce are always changing and you need to change with them! Star Realms: Scenarios is a new 20-card expansion pack for the hit Star Realms Deckbuilding Game. Packs contain 20 unique Scenario Cards that change how Star Realms is played. Shuffle the Scenario Cards, flip one over, and the rules listed on that card affect both players for that game.
