About this card
Mark of Antiquity, printed in Japanese as Ancient Symbol, does nothing for Groudon itself and instead keeps Kyogre ex and Rayquaza ex from attacking on either side of the table. The Rayquaza ex it names had been in Japanese boosters since Rulers of the Heavens the year before. Rock Tumble ignores Resistance, a name first printed on a Graveler in Neo Revelation.
