Zekrom GX SM138

Zekrom GX SM138 is a black star promo from the Sun and Moon Promo series, identified by its SM prefix and promo numbering. Promos like this were distributed outside the standard booster packs, often through special tins, collection boxes or events, which gives them a place of their own apart from the main expansions.

GX cards were a signature feature of the Sun and Moon era, each carrying a powerful GX attack that can only be used once per game. The GX marker became a clear sign of a chase card for both players and collectors. Zekrom is a legendary Pokemon and one of the cover mascots of its generation from the Unova region, which makes this promo GX a notable pick.

Collectors look for Sun and Moon promo GX cards because they combine the era defining GX mechanic with exclusive distribution. This Zekrom GX suits anyone building the SM promo run or collecting legendary Pokemon from the Unova region.
