Background
Japanese Team Magma's Groudon EX 15/34 is the Ultra Rare from CP1 Double Crisis, dated 30 January 2015. Official listing marks 1st Edition. Eske Yoshinob drew the full art.
Double Crisis sold as Magma or Aqua themed packs. This EX sat in Magma packs. Team Aqua's Kyogre EX is the pair card from the same mini-set.
Art talk notes Magma colors and the red orb from the Omega Ruby line. Collectors treat it as a Hoenn faction piece, not a main-set bulk EX. High-grade talk often cites centering and pack edge wear.
