Sounds like a cool idea. I might consider a split on tournament winnings, but the risk to me on that is I can't control how someone plays my deck. The mastery of the game entails choosing your lineup and the order of the line up. That order is very important because if you get it wrong you can potentially damage a sure win. I've seen it happen. It's like playing a linebacker as a safety. He might make a great linebacker and an awful safety.
