I like the idea, but I have one suggestion for the job.
Maybe this person can also go back through all of the updates and put all of the card changes in one place, whether its different art or cost/ability changes and how these changes effected the game.
For example: I could look at this thread, made by historian, and find out that sundial used to last 2 turns, see oty and leaf dragons old art, find out when stuff like rares and the oracle were introduced, etc.
