That was a challenge noticed by the entire Heavenly Federation. If one were to say fantasy card viewership had gone a little slack, by now, absolutely no one wasn't watching attentively. Some of the reporters were even introducing the Black-Line Star Listing to audiences beyond the Heavenly Drum Village District; it was a ranking unique to that district, after all.
When the audience started to understand the value of the Black-Line Star Listing, the viewership for that battle challenge surged. Any contest between aces would always be highly anticipated. Classes in many schools' card artisan departments were suspended on the spot, all of the teachers turning on the fantasy card viewers in their classrooms.
