The Pokemon Trading Card Game: Primal Clash expansion set was released in February of 2015 and features several never-before-seen Pokemon as well as several new variations on existing Pokemon. The set includes 145 cards with 109 distinctive Pokemon. This expansion is set in the Hoenn region, home of the legendary Kyogre and Groudon.
The set includes a couple of new mechanics; Mega Evolution and Ancient Traits. Mega Evolution is a powerful card feature that allows a Trainer to evolve their Pokemon mid battle and unlock new attacks, abilities, and higher stats. Ancient Traits provide Pokemon with new abilities and powers based on primal creatures like Kyogre and Groudon.
