The popular run of the 666 series was a gift from the devil. Three years ago, the 666 Cobalt Blue and Crimson Flare sparked what was one of the most popular catalogs. What followed was the Emerald Hellfire and Purple Inferno, each with a different twist to showcase the different designs that could appeal to collectors. And last year, we introduced the COLD FOIL 666 Greedy Gold and Skeletal Silver to take this series to the next level. With that said, your support is what motivates us to come up with fresh new designs each year, with us reaching the 4th anniversary, allow us to introduce you the 666 V4 Rose Gold & Frostbite Playing Cards! https://www.kickstarter.com/projects/riffleshufflepremium/666-rose-gold-and-frostbite-cold-foil-playing-cards/
