For an event of this size pre-registration is a must: if you don’t pre-register to lock in your spot at a YCS, you might not be able to compete! With a total player count of over 3200 competitors in the main event this weekend, a grand total of 2862 Duelists pre-registered to guarantee their spot in the tournament.

But once your pre-registration’s complete, you still need to submit your decklist online. And with thousands of Participation Prize game mats and Field Center Cards to award, Duelists had to check in yesterday to get their swag. The line for check-in on Friday? It was no joke, winding around the side of the building here at the Los Angeles Convention Center. Here are some photos of the check-in line yesterday as anticipation was building for the 250^th YCS.
