These collector packs of gold foil and red foil playing cards are a Kickstarter campaign exclusive, meant as an Add-on to the original game.
The cards are perfectly functional — 52 standard cards plus jokers, poker format — but that's not what you're buying them for. You're buying the presence at the table. The reflection of the foil when you pass the deck. The weight of the button when you place it in front of the current dealer.
It's the kind of item that poker lovers keep on the shelf, not in a drawer. And that those who already own the base game of Hell of a Deal add to complete the set.
