Suggested by Sonic Rouga Aragami is a pretty powerful duelist. He may not have gotten an Omni Lord, but fortunately Tetsuya’s wasn’t very powerful. Asmodai never really did much in omni mode and the rest of Tetsuya’s monsters are fairly weak as well. It’s a staple of magic world to use weak monsters since the focus is on spells and traps while Rouga has the opposite approach. I’d say that they’re about even with monsters when it comes to pure numbers, but Rouga’s are stronger and he can fight a lot better than Tetsuya can. That’s enough to give him the win. Rouga Aragami wins.
