Kids and teens, usually into gaming, roleplaying, and obviously collecting trading cards. Info about the audience can be found at http://forum.yugiohcardmaker.net.
The primary colors of the logo should red and blue; feel free to incorporate any Yu-Gi-Oh related symbols or fonts into the logo. I would like it to be kind of modern looking / high-tech, without looking too cheesy. Honestly, feel free to experiment with whatever you think looks good; as you can see by the current logo, there isn't some kind of distinct symbol or brand that needs to be replicated.
Update: Experiment with using a blank Yugioh card in the logo.
