These Signature Series character cards come individually in a protective sleeve. Pictures are of front and back of each card to show the casual side and unchained side. These cards are meant to be used in conjunction with Legends of the Chains: On-Course Disc Golf Card Game, sold separately. See the game in action here:

HOW TO PLAY
Each player receives 1 double-sided Character Card at game start, which determines the powers they will be able to use during the disc golf round.

Powers can help you gain an advantage (e.g., get a rethrow) or hinder an opponent (e.g., make them putt on one knee).

Casual Powers are available for use immediately, but can only be used at certain times on any given hole (e.g., at the teepad). Unchained Powers can not be used until a player completes a challenge (e.g., make their first birdie).
