With the Maximum Gold El Dorado box, Yu-Gi-Oh! TCG brings back Gold Rare cards that have raised golden outlines, borders, symbols and icons on popular cards. This set will feature ten more cards with variant artwork and the gold treatment, like Knightmare Unicorn. There will also be a new Xyz Monster with an ATK boosting effect, and a Premium Gold Rare Chamber Dragonmaid.

Cards that dont get the Premium Gold Rare treatment will still get a bit of gold themselves, appearing as gold lettered Rare cards instead of the standard silver lettering.

Each box will include 4 packs with 7 cards each: 2 Premium Gold Rares and 5 gold-letter Rares.
