I know of a system that would allow this easily. It would require everyone to download a system called Byond. In the hub-listing, it has a game called Duel Monsters Genesis, that you're allowed to create your own server for, and if needed put a password on. It's quite easy to duel from there. Once you have Byond and your server, it's a matter of creating your deck and learning how to duel. Having done this before, i could help and teach you the Byond DMG systems, should you go with this platform. But for the sake of dueling alone, if you could find a browser-based yugioh platform, that would be more efficient.
