Hey Parker! It's actually not a gimmicked deck. Sub Rosa empowers you to create single cards that you can easily locate anywhere in the deck - after it's been completely shuffled, by a spectator. You can make these cards with tools you have at home. The cool part like Josh pointed out, is that very few magicians in the world will be able to spot anything (let alone unsuspecting spectators). Use it as a tool to supplement your magic routines, or standalone as a demonstration of skill. You can make just ONE card, a group, or multiple groups "Sub Rosa" cards and effectively be able to access them at any time. Extremely versatile and powerful.
