Reference cards are not actual cards that a player can include as part of their deck, but are instead cards that can help a player to keep track of their status during a game. Each starter deck comes with at least one copy of a Score Slider Card and a Turn Card.
- The Score Slider Card tells a player how many action tokens a player can collect during their Ready Phase, based on the player with the highest score.
- The Turn Card lists some of the basic actions a player can perform during their Main Phase.
By placing the Score Slider Card on top of the Turn Card, a player has an easy means of keeping track of their current score.
