Rumors are rumbling through the Pokémon TCG community as hints of the Mega Horizon Set, slated for March 13, 2026, promise to ground the Mega Evolution Series with earth-shaking power! Following the gallant charge of Mega Valor, this sixth expansion draws from Pokémon Legends: Z-A’s vast horizons, spotlighting Ground- and Rock-type titans like Mega Tyranitar ex and Mega Garchomp ex. With colossal HP, terrain-altering attacks, and the intense 3-Prize mechanic, Mega Horizon is poised to reshape the meta and thrill collectors with its rugged, expansive vibe.
Speculation points to around 150 cards (110 main set, ~40 secret rares), including eight Mega Pokémon ex such as Mega Excadrill ex and Mega Camerupt ex, alongside seven regular Pokémon ex and 18 illustration rares. The set’s silhouette-style artwork is expected to evoke vast landscapes, with ultra-rare full-art Trainers, Items, and a new Ground-type Special Energy adding strategic layers for deck innovation. Whispers suggest Mega Tyranitar ex’s Quake Rampage attack could dominate board control, while collectors buzz over the set’s nine special illustration rares for their dramatic, horizon-spanning designs. Gold hyper rares, especially Mega Garchomp ex, are already stirring investment speculation.
Prerelease events are rumored to start February 27, 2026, with Build & Battle Boxes featuring promos like Sandshrew or Diglett, offering early ground-shaking action. Pokémon TCG Live is set to integrate the set on March 12, with exclusive quests and sextuple XP rewards to test new decks. On the horizon, April 2026’s Mega Eclipse set might eclipse with Mega Lunala ex, hinting at lunar mysteries ahead.
