I guess that everybody uses deck protectors for their cards. I'd like to know what your opinion is about the plethora of available colors, and how you organise them. Do you only use one kind (color) of deck protectors for your cards? I find this to be difficult because I have so many cards and can't find as many sleeves of the same color each time I go to my local shop. One solution that I'm implementing right now is to use one color for the light side cards and another for the dark side cards. I have chosen tsunami blue for the light side and lava red for the dark side. As for the neutral cards, I'm thinking of "splitting" them between the two sides and using blue or red sleeves. This way you can make all-blue light side decks and all-red dark side decks. The only drawback is that each neutral card is "assinged" to one specific side. Another thought is to use a different color for the neutral cards and be free to use them in both light and dark side decks, but this way your opponent will know if a card you are building is a neutral one. Finally there is a question whether you use the same colors regardless of the set of the cards (AOTC, SR, JG) or not.
