In addition, if you purchase either the DX Gotchardriver or the DX Exgotchalibur starting on November 25th, you will get the Ride Chemy Trading Card Kira Card Set of 2 as part of a special campaign. That set comes with the UFO-X and the X ASSEMBLE Ride Chemy Cards, which will unlock more forms for Kamen Rider Gotchard, namely Super Gotchard Cross UFO-X and Star Gotchard respectively.
Like all Kamen Rider toy campaigns, items are limited in quantity, and are on a first come, first serve basis, so get it while supplies last. Lastly, the UFO-X Ride Chemy Trading Card is planned to be available outside of said special campaign.
