Batman usually doesn't have much downtime. When he's not busy being Batman and obsessing over how he can stop all crime he's pretending to be Bruce Wayne...and somewhere in there he finds enough time to sleep for 15 minutes(since that's all he needs). However, if he did have some free time, I'm sure he would reach for the Batman Caped Crusader Playing Cards!

The Caped Crusader card set takes a standard deck of 52 playing cards and adds a bit more justice. Who needs some boring dude with a lance and crown when you can have a set of cards inspired by the Dark Knight!
