Sounds like a great idea to me. It'd be cool to have "annuals" for each year, lists of the decks that were published in that year, and keep them pinned to the top of the Plethora - no comments allowed, just the list created by you, and if desired comments can go in a different topic. If known, you can even pop in actual release dates, or at least release months. I know, it's a lot of work - but it would be very cool and very handy for collectors. I'd be willing to help work on a good way to compile and sort the data for you if you wish - you send me the info, I'll send you a well-formatted, easy-to-understand way to show it. I'd say you wouldn't need to go further back than, say, the start of Ellusionist, since they kicked off the modern custom deck craze. For the older and very popular releases, a single chart covering them as the "archive" would work - stuff like Jerry's, Virginia Slims, old Arrcos, etc.
