Pokémon TCG Mega Evolution: Delta Reign Product Lineup: ETB, Pokémon Center ETB, Booster Box and Build & Battle

Correct as of 12 Nov 2026, 22:45 GMT (Europe/London)
Every product configuration, pack count and promo card below comes from Pokémon.com's official Mega Evolution: Delta Reign Product Showcase. We do not include retail prices or secondary-market card valuations. Checked again on 12 November 2026: that showcase still does not publish a retail price, so this page still does not quote one.

What products are in Pokémon TCG Mega Evolution: Delta Reign? The official product line-up features five sealed products: the 36-pack Booster Display Box, the 9-pack Elite Trainer Box (with one full-art Kyogre promo), the 11-pack Pokémon Center Elite Trainer Box (with two full-art Kyogre promos, including a Pokémon Center stamped version), the Build & Battle Box (a 40-card deck with 1 of 4 foil promos plus 4 packs), and the 6-pack Booster Bundle. Prerelease events with the Build & Battle Box began at participating local game stores on Saturday 24 October 2026. The expansion launched on Friday 6 November 2026. Pokémon's current product showcase and the 2 November 2026 product roundup list wider Build & Battle Box availability as Friday 20 November 2026.

Elite Trainer Box vs Pokémon Center Elite Trainer Box

Both Elite Trainer Boxes feature Kyogre on the box art and include the full suite of tabletop accessories needed to play and store cards from Mega Evolution: Delta Reign, but the Pokémon Center exclusive version adds extra packs and a second promo card.

Standard Elite Trainer Box (9 packs)

• 9 Mega Evolution: Delta Reign booster packs (each pack contains 10 cards and 1 Basic Energy)
• 1 full-art foil promo card featuring Kyogre
• 65 card sleeves
• 40 Pokémon TCG Energy cards
• Damage-counter dice, a competition-legal coin-flip die and a plastic coin
• A printed player's guide to the Mega Evolution: Delta Reign expansion
• A sturdy collector's storage box to hold everything together

Pokémon Center Elite Trainer Box (11 packs)

• 11 Mega Evolution: Delta Reign booster packs (two more packs than the standard ETB)
• 2 full-art foil promo cards featuring Kyogre: one standard full-art foil promo and a second copy stamped with the Pokémon Center logo
• All of the same sleeves (65), Energy cards (40), dice, coin, player's guide and storage box included in the regular Elite Trainer Box

Pokémon.com's UK Product Showcase lists 6 November 2026 for the Booster Display Box, both Elite Trainer Boxes, and the Booster Bundle. The same page lists the Build & Battle Box as available 20 November 2026. The Pokémon Center Elite Trainer Box is sold directly through Pokémon Center. Because UK high-street and independent hobby store delivery windows can occasionally vary by distributor, check your chosen retailer or the Pokémon Center UK storefront directly for stock availability.

Booster Display Box and Booster Bundle

If you already have sleeves, dice and storage boxes and only want booster packs from Mega Evolution: Delta Reign, two products strip out the accessories:

Booster Display Box (36 packs)

The Booster Display Box is the largest sealed product in the line-up, containing 36 booster packs. With 10 cards and 1 Basic Energy in every pack, a full display box delivers 360 expansion cards plus 36 Basic Energy cards, making it the standard choice for collectors chasing Mega Evolution Pokémon ex (including Mega Rayquaza ex, Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex) or the set's illustration rare and special illustration rare cards.

Booster Bundle (6 packs)

The Booster Bundle packs 6 Mega Evolution: Delta Reign booster packs into a compact box without sleeves, Energy bricks or dice. It sits neatly between single blister packs and the 9-pack Elite Trainer Box for players who want a six-pack opening on launch day (Friday 6 November 2026).

Build & Battle Box and Prerelease events (from 24 October 2026)

The Build & Battle Box was the earliest way to open Mega Evolution: Delta Reign, at Prerelease, before the 6 November street date.

What is inside the Build & Battle Box?

• A 40-card ready-to-play deck built around key cards from current and prior expansions
• 1 of 4 unique foil promo cards included inside that 40-card deck (Masquerain, Magmortar, Enamorus or Kommo-o, per Pokémon.com's official prerelease preview)
• 4 Mega Evolution: Delta Reign booster packs to open and fold into your 40-card deck before matches begin
• 1 code card for Pokémon TCG Live

How Prerelease events work and when they run

At in-store Prerelease tournaments, players build and play with a 40-card deck and four Prize cards instead of the standard 60-card, six-Prize-card format, making games faster and friendlier for newcomers.

Pokémon.com's 28 September 2026 prerelease article says participating Play! Pokémon stores began selling the Build & Battle Box on Saturday 24 October 2026, and that players who missed Prerelease could buy the box when the expansion launched. The product showcase and the 2 November 2026 product roundup, both checked on 12 November 2026, list that wider availability as Friday 20 November 2026. Community event calendars placed the main prerelease window through Sunday 1 November 2026. Pokémon.com does not enforce a single end date on the web because each local game store schedules its own flights and stock. Use the official Play! Pokémon Event Locator on Pokémon.com or check directly with your local hobby shop.
