On an Eclectic Deck of Cards

The other day I found a single playing card. Just one, it was the seven of spades. So I picked it up and put it on my desk. Later on I found another card, this time the two of hearts, so I put it with the first card. Then it struck me; A really cool idea. What if I made a deck of playing cards out of individual cards from other decks?! It would be pretty useless as a long term deck of cards because you could memorize the outer design of card to know which was an ace. I don't really care, I think it would just be a really neat deck of cards especially if each card had a story or a special person who had given it to me.
