By Era SortingFollow

What I've been doing (assuming this is for item searches) is excluding all expansions on the right side to back into original release. Even then, you've got a lot of chaff to visually sort through (you'll know it when you see too high stats that certain results were post-classic adds). Also, I spent some time walking through a by-zone search of results to get some initial items in the range of my 25 level main to go after.
