I don't have a big collection and keep in a canvas bags that has a waxy lining. Works well. I put dried rosemary in the bag. It doesn't touch the decks themselves, they're all in Dark Nature Cases, but I like the smell and it's supposed to be protective and help keep away negative energy. But I like that bit of nature in with my decks and the smell, so anything else it does is a bonus!
