Gamblers live to take risks and beat the odds. They know that there is no such thing as a losing hand, and that winning is all about knowing how to play the cards that you’re dealt. Fortune seems to favor these practiced decievers and natural rogues, who have a seemingly endless supply of clever solutions and second chances.
The Gambler Specialization Deck contains:
2 cover cards (including a reference guide for each deck)
20 standard sized talent cards
