Dice Throne Season 2 Randomizer Storage

I recently played Dice Throne and purchased the Season 2 battle chest and also got the promo cards along with it. If you've seen the Battle Chest, you know how nicely everything fits in the box and the excellent organizational design.

The promo pack came with a very nice randomizer deck to help select which characters to play. However, they completely clash with the design of the Battle Chest. There simple isn't a way to nicely put them in the box.

I came up with this solution of a deck box that slides onto the side of the chest in the game manual slot, and overlaps a divider to take up less space. I only have Season 2, so this won't fit randomizers from all seasons or sleeved cards, but the model could easily be modified to do so.
