Thanks for all the answers
I'm thinking about buying atm the killer clowns bike and looking for other interesting decks that have a unique design and unique Jokers , I'm looking at different stores on the web (US and Europe)
btw, is it possible to collect the Jokers aside? I mean I would collect the decks, but I want to play with them and use them here and there, but I won't play with the jokers themselves (and the add cards or any other extra card that is not needed in gameplay), so can I like collect them and keep them only in a "perfect" condition by the side and the rest of the deck as a different collection? Like to showcase the Jokers in 1 place and the decks them self in another place
I'm guessing that you're a younger collector, new to the whole thing. That's cool.
There's a popular version of card collecting called "single swap." Those collectors love the card back designs, but find the hobby a little too expensive or that it take up too much space - but for whatever personal reason, they collect single cards from a deck rather than the entire deck itself. It's a lot cheaper to collect singles than entire decks, and an entire collection can fit on a single bookshelf with room to spare, while I can personally attest to the fact that a collection with a few thousand decks in it takes up a LOT of space and is VERY HEAVY (I moved a few months ago)...
Some collectors of single swaps specialize by collecting a specific card from a deck. Most popular would be the Aces of Spades and the Jokers, followed by the court cards. They'll get that same card from every deck they collect, and just that card. Finding specific cards from each deck is a little more challenging, because by focusing, for example, on only the Ace of Spades, you've just eliminated 53/54ths of all the single swaps on the market as potential candidates for your collection. That would be 52/54ths eliminated if you're a joker collector, unless you specialize there, like getting only the "color" joker, the "big" joker or the joker that doesn't have the USPC Guarantee on it.
