Released on March 25, 2015, Double Crisis is a special mini expansion in the XY series featuring just 34 cards centered entirely on the rivalry between Team Aqua and Team Magma from Pokémon Omega Ruby and Alpha Sapphire. The set pits Team Aqua's Kyogre-EX against Team Magma's Groudon-EX, with all Pokémon in the set belonging to one of the two villain teams and available only through specially branded pin collection boxes. As one of the smallest and most thematically focused sets in TCG history, Double Crisis offers a unique collecting experience with its team-based aesthetic and full art EX cards depicting the rival team leaders.
