Originally I was thinking of opening 10 to 12 boxes of 1a and try to see if I can pull a Shiny Charizard GX, but then realized that there will be 2 Shiny GXs missing from the set (there are 38 Shiny GXs in Ultra Shiny, but only 36 in the new set), and one of them will be either Fire, Psychic or Metal, so I ended up getting cold feet and only bought 1 box
