I recently bought a 2 pack of red and blue bicycle cards for 6 dollars at target to practice learning how to shuffle and do magic tricks but they are extremely hard to bend. When I try to ruffle them they don't come out individually and instead come out in clumps. I see youtube videos on how to shuffle cards they seem to bend and ruffle them so easily. I was wondering if I might have gotten a faulty deck or if there is something i'm doing wrong that makes them so hard to bend and so hard to control.
