My favorite aspect of http://www.starcityccg.com is that in their magic section there is a big list of resource links on the Right Side navigation. It contains everything from the DCI banned list, to D'Angelo's rulings (crystalkeep), to Apprentice downloads and patches. Very useful, plus it seems all of their writers have a good sense of humor.
Ok, thanks for all the suggestions guys, I'll be sure to check em out. What I had in mind though, was someway I could look up cards by artist, type etc to help with the creation of theme decks. Easier than flipping though spoiler after spoiler for the different expansions
The Dojo database, if it ever works again, lets you search by artist. If you have MIE you can do it also. Mtgnews has a great database now, but you can't search for artist.
