Hero Realms: Ranger Pack - Rules of Play says:

lay Hero Realms as a deadly Ranger. Track your enemies through the wilderness, call your allies to battle, and take down even the deadliest foe with one well-placed arrow. This Character Pack replaces a player's personal deck in the Hero Realms Deckbuilding Game. Included are 15 cards: a Ranger character card, the Headshot and Track ability cards, two unique scorecards, and a new 10-card personal deck (Ruby, Hunting Bow, Horn of Calling, 2 Black Arrows, and 5 Gold).
