Deck Hound

Clubs, diamonds, spades, hearts, luck of the draw. Deck Hounds are subservient to the cards, not specifically to gambling, but to each suit and each face. Deck Hounds are not luckier than you, they're not inherently luckier than anyone, they just know how to play the game better than you, better than anyone.
