Wasn't Yu-Gi-Oh originally supposed to center around Yo-yo battles, and not a card game? I think I remember my friend telling me that.
It focused on Yami Yugi playing random games and always winning even if the opponent cheated and once he won, he'd punish them in the most a*****e way possible in relation to their behavior/what the game was about.
Like making some escaped con set himself on fire while the guy was pouring vodka by placing the guy's lighter on his hand during a game where they could only move one finger.
Or having the face of a bitchy teacher who wore too much makeup break away to reveal her true, ugly face.
Or making the money grubbing bully think he just had like a knee-high pile of money when all it was was just leaves.
One arc/episode/chapter/whatever in particular dealt with a gang using yo-yos as weapons.
