I put each set in it's own portfolio (Pokemon of course!) in numerical order, I also include the reverse holo's in there too, so a set will fill up the portfolio. Any extras I keep in a Chucks shoe box. I only buy the pre made decks to play for fun, so I'm not making any decks with the extras. I love opening my portfolios and looking through all the cards I have, such fun!
It was perfect, beautiful, like something someone with an overactive imagination would dream up in her unfulfilled fantasies!
