I've recently dove headfirst into collecting and playing Digimon TCG. And as I have completely fallen in love with this game, I want to protect them.. and sort them.

I've already got a fairly simple system in place (Colour>Level>Cost>DP>Multiples>Looks), hoever I wanted to add another level of organization. My initial thought was to perhaps find colour backed inner sleeves and use them to easily tell apart cards while they weren't being used in a deck, and then slide them into cool sleeves when I make decks. Are there any specific brands that this woruld or wouldn't work with?

(Any advice on storing and sorting in general would be appreciated. I still have my old white cardboard deck box from when I was a kid and am considering more of the same if they are still that durable)
