Xiaolin Showdown + Yu-Gi-Oh! Crossover

Hi fans to Xiaolin Showdown and Yu-Gi-Oh! (The first ones with Yugi (The Pharaoh) Joey etc.) I am making a crossover with these two. They are one of my favourite shows so I thought 'why not mix these two together?' So I went into a fortnight of brainstorming, figuring out ideas from "Shall the world of Yugi come to XS?" or "what will be the purpose of this?" etc. Then I came up with it, to make XS characters go into a 16-way tournament of Yu-Gi-Oh. The characters involve: Omi, Kimiko, Raimundo, Clay, Jack Spicer, Chase Young, Hannibal Roy Bean, and Stephanie (Omi's girlfriend in "Wudai Warrior Adventures") Yugi, Joey, Seto Kaiba, Marik, Mai, Odion, Bakura and the rare hunter with the Exodia Deck. The plot of the story is:

The Warriors need to go on a search for an ancient artefact of magical properties, and where might this ancient artefact be? Why in Domino City, home to Yugi Muto, Joey Wheeler and friends. Yugi explains he seen the picture of the magical artefact as a prize of the Battle City Tournament 2. (This time it's sixteen finalists.) But Chase Young, Jack Spicer, Hannibal Roy Bean participate as well, in order to claim the magical object. But the four Warriors get mixed in the Shadow Games, as Marik has returned to his evil self (Not by will.) and joins with Hannibal Bean to try and take down the Warriors and the Duelists to help plunge the world into darkness and seek his ultimate revenge.

I hope that was a good summary. The cards used are exactly like the ones used in the Battle City Tournament. So review telling me what you think, and/or advice, 'cus I got a really good idea for this crossover. Thanks.
