Yeah, that’s what replaced all the King talk.  In episode 1, “There’s only one King—and that’s me!”->”Who’s the Master of Faster? Who rules the duels? That’s right, it’s me!”

idk it just sounds lame to me; keeping the “King of Riding Duel” concept would’ve been better.  It was also at a time when 4Kids was doing whatever they wanted with the dub, and an era I try not to revisit lest I be flooded with trash-talking and extra dialogue, pointless card interruptions made to fit said trash-talking, random plot points inserted for no reason (like Yusei’s amnesia or Ushio working for Jack), and heavy doses of “Let’s rev it up!”.  

Thankfully, though it still has some spotty accuracy issues, the dub comes to be passable come the WRGP arc lol.
