The 10 most expensive Pokémon cards of Primal Clash (Chase Cards)

Two new rules arrive in the same expansion. Ancient Traits debut, giving a card a standing effect such as attaching two Energy in a turn or attacking twice, and Primal Reversion takes Groudon and Kyogre past Mega Evolution into a form that carries its own printed rule. Mega Gardevoir-EX and Mega Aggron-EX sit among the twelve Pokémon-EX spread across 160 numbered cards, alongside new Supporters and Special Energy. The set follows the games Omega Ruby and Alpha Sapphire and reached English on February 4, 2015.
