While this may come off as surprising to some, Vanguard's publisher works closely with Dentsu, which is both the largest domestic advertising firm in Japan and a major figure in the international scene. Having recently covered the advertisement of the 2012 book-turned-film The Lorax, Dentsu's most current move was its closing of ties with the Publicis Groupe, a French multinational company with a similar historic background.
They had previously held a strong strategic alliance from 2002 until February of this year, when Dentsu withdrew from its relationship with Publicis and sold off most of the stock it held in the company. Together with Omnicom and WPB, the Publicis Groupe fought for total domination of the world market, but it can now be taken as a sign of the times that Dentsu is a large enough player to stand on their own in the international scene. During their time with Publicis, Dentsu owned almost 10% of the company's shares, now lying at around 2%. Despite this move, Dentsu and Publicis have both publicly expressed a desire to continue working together and maintaining a strong professional relationship.
It isn't quite to the level of televised matches, but Cardfight has certainly made its way into the competitive stadium. The advertisement can be seen in the video below from 0:16 to 0:19
