The showcase calls Mega Evolution Pokémon ex the stars of the set. A TCGplayer seller guide from October 21 adds detail: four Mega Evolution Pokémon ex, six Pokémon ex, and six Stadium cards that combine into three Legendary Stadiums. It also says most of the cards come from the Japanese set Storm Emeralda.
Prerelease events and Build & Battle Boxes
Build & Battle Boxes show up first at local game stores during prerelease events, then reach wider retail on November 6, according to the showcase. TCGplayer's guide dates the prerelease window from October 24 to November 5. Formats and dates vary by store, so check with your local shop before you go.
What it means for collectors
The Pokémon Center ETB is the version to watch if you collect stamped promos. Its second Kyogre carries the Pokémon Center logo, which the standard ETB doesn't include. The two extra packs make it the larger box, but it's sold only through Pokémon Center.
If you're weighing which box to open, our booster box vs bundle vs ETB guide compares packs per product. For the cards themselves, the Delta Reign chase cards guide covers the Mega Rayquaza ex chase and the Japanese cards the set is expected to share.
What's next
- November 6: retail release, and the start of three retailer gift-with-purchase promos (Kyogre, Groudon and Giratina) that Pokémon announced the same day as the showcase.
- After launch: the full English card list, plus community counts of how often each rarity turns up, since The Pokémon Company doesn't publish those numbers.
