The Champion's Path Secret Rares have been leaked out, someone obtained the French Elite Trainer Box (Booklet) early and shared this image on social media. This set contains Hyper Rare Charizard VMAX and Shiny Full Art Charizard V, presumeably from the upcoming Japanese Set S4a High Class Pack Shiny Star V. Suspicous Food Tin has a Gold Card and Hop Full Art that is a promo in Japan, has been included in this set. Kabu HR and Piers HR were cut from Darkness Ablaze and have been included in Champion's Path.
HR Charizard VMAX is a very limited promo card in Japan, only obtainable in a tournament. This is the first time, a Shield Battle promo has been made available outside of Asia in a set. Previous Shield Battle tournament promo's during Sun & Moon were never made available outside of Asia.
