Damn, missed most of the yugioh talk.
I haven't found any place that does this, but dollar general used to sell varity packs of trading cards. I loved those. It would have a couple packs of a few diffrient TCG's (Yugioh, pokemon, two diffrient Gundam series, DBZ, and others that I'm forgetting.) It was $5 for one, and they had 5 packs each. This happened a while back, I think about... two years before GX was released.
I've lost all the cards I got from them, and that pisses me off. Mainly because of the Gundam cards since I've never found any more packs.
Anyway, I've given up on organizing my cards. I keep all the commons in spare collectors tins, and in card boxes. I have all the rares in sleeves and in a card box. (I have a small amount of cards in the magnetic plastic holders too.) I have a LC2 binder that I haven't bothered peicing out, but meh, the cards are safe enough in that.
When I used to organize them, I'd seperate them by traps, spells, and monsters. I'd then divide monsters by type (N/E/F/R) and then element. I'd have the elements going alphabetically, and then seperate the seperate elements by level before putting the seperate levels in alphabetical order. Took a long time to organize them, but it made it easy to find a specific card.
Anyway, FOOD! Your sig makes me hungry... Even though I just ate (Before you ask, bacon cheeseburger :))
You know what I really want though? This.
