The underground chapter. Series 2 arrived January 2023 with a radically different visual identity — underground artist Alex Pardee brought a darker, more surreal sensibility to the GPK × MLB crossover. At $24.99 per pack, it's the priciest of the three standalone series. Series 2 is also the most complex set structurally, with 10 parallel levels including a Baseball Stitching Foil unique to this set, plus "No Name" variants and the ultra-rare Baseball Guy Pencil Drawing at 1:100 packs — the rarest pack-pulled insert in the entire GPK × MLB ecosystem.
