Primal Clash will be the name of America’s fifth XY set and will hit store shelves in February. The set will obviously be our version of Japan’s Tidal Storm / Gaia Volcano set and will feature the premiere of Primal Kyogre-EX and Primal Groudon-EX. Primal Clash will also see the release of two Elite Trainer Boxes this time around, featuring either Primal Kyogre or Primal Groudon. Along with Boundaries Crossed (Freeze Bolt / Cold Flare), which was based on Black 2 and White 2, this is the second time a set based on a video game has not been named after it (e.g. EX FireRed & LeafGreen, XY, etc).
Update (11:00 AM) – New info just came in! The set will feature over 150 cards, including 12 Pokemon-EX and 4 Mega Evolution Pokemon-EX.
