The set will feature a whopping 150 cards! Unlike normal Japanese sets, each booster pack will come with 10 cards — of which four will be holo! One of the four will be guaranteed to be a Pokemon-GX.
The packs will cost 500 yen, which is more than usual due to the increased pack size and guaranteed holos. This is also why the set is named “Ultra Shiny,” since it will include a lot of shiny foil cards.
The set will likely feature many Pokemon-GX reprints from the Sun & Moon era. If the pack art is anything to go by, it could include reprints of Buzzwole-GX, Zygarde-GX, and Zoroark-GX. Though they could also be normal Pokemon in the set.
