The event will now start at  October 23 at 3 PM Eastern Time/12 PM Pacific Time, instead of October 15th. The citation for the event being delayed is because Twitch has decided to hold off starting the event until the end of TwitchCon, their convention, as many attendees of the event apparently expressed disappointment that they’d be missing a meaningful portion of the 236 episode Yu-Gi-Oh! marathon due to the convention being held from the 20th to 22nd.

As well, the Team FourStar Pre-Show for the event has also been delayed.
