You can create your own Yu-Gi-Oh by going to the website yugiohcardmaker.net, filling in the necessary data, and then uploading a picture. It should be noted, however, that cards created on this website are made purely for fun and cannot be used in official tournaments.
First the card must be given a name. Then, one must select the card type. If one chooses Monster, one must then select what type of monster it is: Normal, Effect, Divine, Gemini, Spirit, Toon, Tuner, or Union. Next one must choose an attribute: Light, Dark, Fire, Water, Wind, Earth, or Divine. The card must then be assigned a level, anywhere from 1-12.
Next, one must select the card rarity: Common, Rare, Super Rare, Ultra Rare, or Secret Rare. The creator then has the opportunity to upload a picture from his or her computer that will be the face of the card. An ID and Type must then be added, followed by a description that will appear on the card. The next step is to add the Monster's ATK and DEF points. The higher the points, the stronger the card.
At the end, the creator can also put a year and serial number on his or her card to make it look authentic. The final step is to click on the Generate button and the website produces the image of the card.
A user also has the option to create a Spell, Trap, Ritual, Fusion, Synchro, or Xyz card, following the same format as the Monster.
