I recently bought a beautiful tarot deck (I'm a low-key deck collector, each deck reads a bit different) that was really too sticky to fluidly use. The cards stuck together really bad for some reason and it hardly faded at all after some use. I'd been desperately trying to figure out how to make this beautiful deck not sticky. I found an online tip, that said to put the cards and talcum/baby powder in a bag and to shake them around. So I took my cards, a plastic grocery sack, and baby powder and tried it for myself. I put the cards in and gently shook them a bit so they would come apart and leave room between them for the baby powder. Then, I puffed (tipped over the bottle and lightly squeezed, you don't need a ton) some baby powder into the bag and shook them around a bit. After shaking then a couple minutes I took them out of the bag and viola the cards weren't sticky. Some do still stick together a bit but with a little shuffling, that should come out as the baby powder spreads. So for all you with sticky cards, baby powder.
