Need help making a power that is essentially like Yu-Gi-Oh Season 0, but set in a world where most powers are more directly combat related

Basically, I'm trying to make a guy whose power is to force others to play a game instead of having an actual fight. The created game has to involve the target's powers in some way, while still giving the user some chance at victory if he's smart about it.

The main problem I'm having is how to make the games fair for both my character and whoever he's facing without invalidating whatever unique powers his opponents will have. I guess I could say that whatever game he creates has to have a possible win condition for all contenders, so he'd effectively be powerless during the games and would have to use more creative methods to win, but I'm afraid it'll end up being too "genie-like" in the sense that it'd be less about strategy and more about making rules with deceptive wordplay, which I don't want my character to rely on (even though Yugi did that a lot in season 0 lol). I want to know if anyone has anything to say that I hadn't already thought of yet or not. Thanks in advance.
