This is an insert for the D&D Desk- based card game Dungeon Mayhem.
I printed this because of the recently released Marvel Madness expansion which adds four decks themed around Marvel Comics, leaving us with an excess four decks which don't fit into the original 12-deck box supplied with the Monster Madness expansion.
This insert fits all 16 decks, with seperate token holders for heart and character tokens, and space to the side for all of the instructions/ original token box. It fits neatly into the Monster Madness box which comes with the third expansion to the original game.
