In the Japanese version, a "side:Unity" Token Card is included at random in 1000 packs. The Token includes a serial code that can be used to apply for the Quarter Century Unity & Pride Campaign.
In the Japanese-Asian version, there's an additional Campaign Pack in each box that included either a winning ticket or 1 of 6 Field Center Cards. The serial code from the winning ticket could also be used on the official website to apply for the campaign mentioned above.
