I really liked Robert's original design, but wanted to remove some of the dividers so I could continue to add in fan-made monsters.  I also liked the idea of having a draw-pile for each deck with its own discard pile so things stay tidy while you play.  I'm not 100% pleased with the need for "spacers" for the in-box storage, but it was that or make the draw-piles unnecessarily big out-of-box.  I haven't yet printed them and don't think they're absolutely necessary, but if I ever travel with this game it will be nice to know they won't shake around too much.
