Card Organization: Multi-Color Cards
I follow the same procedure for organization that my LGS does.  I have a big 4 row box. In each row, I have a set.  So, right now one of my boxes has (in order): Innistrad, Dark Ascension, Avacyn Restored, M13.  What do all of these sets have in common?  They rotate out at the same time.

Now, for organizing each set, I follow WoTC's number system, and I put like cards together in penny sleeves (clear sleeves that generally cost $1 per 100). This way, they are organized by color, and then alphabetically.  This makes searching for cards much faster, at least for me.

Now, the order that WoTC does things is Colorless/White/Blue/Black/Red/Green/Gold/Hybrid/Artifact/Lands.  Also, if you look at the bottom of each card, there is a number associated with it.  For instance, the One Thousand Lashes you linked, is card number 183.  So, it would go 183rd in my box.

I hope that this helps.
