How often do you replace your playing cards ?

I use decks for two or three gigs max. Depends on the humidity, time of year, gig conditions, spectators and how many are signed/ruined. If the deck is fresh I may use it to make up a complete deck with another used pack but never mix old and new cards. For practice I use older cards but once they get past a certain point I scrap them. No specific time it's more a condition thing.

Usually when they fan poorly, and when doubles start to look messy, I toss them out. They start to stick together which makes stuff like multiple shifts and shuffles a lot tougher.

Normally after 3 days, 16 hours, 44 minutes and 15.3 seconds.

But it depends.

I hate these.imprecise responses! ;-p
