What you see in the photo above is the prototype of a new cardholder for the game, its 8 wells will fit all the bridge-size cards from the EU:tPoP Deluxe Edition with sleeves, and when closed, it fits neatly into the game box, so this is the perfect storage solution for your cards.
Moreover, it is not just for storage. When the top part is moved into the "staircase" position, the cardholder also provides a brilliant way of keeping your gaming table less cluttered while you are playing EU:tPoP. You can use the wells on one level for the Action and Trade decks, and keep the corresponding discard piles in the wells on the other level.
The cardholder fits neatly into the Deluxe Edition and Extended Standard Edition boxes once you remove the base tray. The player trays will then go into 2 stacks next to it, and the mini-cards will go in a small tray that fits in the gap in the middle here. Boards, mats and booklets go on top.
