Homemade Yu-Gi-Oh deck holders provide you with a personalized, stylish alternative to commercially manufactured versions. You can use old Yu-Gi-Oh cards that you no longer play with to create your own deck holder to replace a lost box. This process requires you to choose 16 cards you no longer use and cut and glue them together to form a box.
Create the Pieces
Select 16 Yu-Gi-Oh cards that you no longer want to use.
Measure 1/2-inch from the edge of each of two cards and make a mark using your pencil. Place a small amount of glue on the inside of the 1/2-inch mark of one of the cards, then attach a third card so that it aligns with the first, overlapping it at the 1/2-mark you made. Attaching the third card to the other card, again overlapping at the 1/2-inch mark in the same way. Repeat this process so that you have two of these strings of three cards.
Place two cards together vertically so that the width of the two cards together equals 2-3/4 inches. Adjust the width of the two cards by sliding one underneath the other, then glue them in place when their combined width equals the appropriate measurement. Use this process again to make a total of two of these pieces that are 2-3/4 inches in width.
Glue two cards together horizontally by placing one underneath the other so that it is about halfway underneath the top card.
Take one of the 2 3/4-inch pieces (from Step 3) and measure and mark 1-1/2 inches from the edge across the width. Place another card horizontally across the top of the 1-1/2-inch piece and glue them together so that it is approximately centered across the top. This will become the top flap of the box.
Measure and mark 1-7/8 inches horizontally from the edges of two cards; cut across the line on each of these cards. Measure and mark 1-1/2 inches from the edge of the cut pieces vertically. Line your ruler up with this mark and trace a line from the edge of the card to the corer on both cards, so that you have two separate triangles facing in the opposite direction. Cut out the triangles and save the remaining pieces.
Assemble the Box
Take one of the strands of three cards (from Section 1, Step 2) and measure across the width 1/4-inch from the edge of the center card on each end. Fold the cards inwards along this mark. Repeat this process on the other strand of three cards. Glue these two pieces together so that they form the body of the deck holder; it should be slightly larger than the length of a Yu-Gi-Oh card.
Take one of the 2-3/4-inch pieces (from Section 1, Step 3) and the piece with two cards glued together horizontally (from Section 1, Step 4) to create the bottom of the box. Place the horizontally glued cards across the center of the other piece and glue them together. Fold up the sides of the horizontal piece, then place it on the bottom of the deck box. Glue the two folded-up flaps to the side to secure it in place.
Take the two pieces with the triangle cut out (leftover from Section 1, Step 6) and glue them onto the lid portion of the box so that they align with the card going horizontally across the other two cards. Fold the bottom portion of the vertical card in so it aligns with the edge of the flaps. Fold in the flaps under so that they are even with the vertical card.
Insert the flaps into the body of the deck holder and glue them in place. Bend the portion of the top card that hangs over the body of the so that it fits inside the body of the deck holder.
