Delta Reign Prerelease Promos: Four Pokémon to Know
Masquerain, Magmortar, Enamorus, and Kommo-o are the four Delta Reign Build & Battle promos. Find the prerelease dates and box contents.
PokéBeach revealed the four Mega Evolution—Delta Reign prerelease promos, and Pokémon’s own prerelease guide now names the same lineup: Masquerain, Magmortar, Enamorus, and Kommo-o. If your favorite is one of them, you have a reason to mark the prerelease window. If not, there are still fresh cards to play with before the full set lands.
The four promos
| Foil promo | What Pokémon’s guide highlights |
|---|---|
| Masquerain | A Bug Out attack that scales with your other Bug Out Pokémon |
| Magmortar | Buddy Boost attaches Fire or Lightning Energy to Magmortar or Electivire |
| Enamorus | Incarnate Solidarity helps a group of Forces of Nature Pokémon handle attack costs |
| Kommo-o | Beat Scales accelerates Energy to Dragon Pokémon |

PokéBeach calls these alternate-art versions of cards in the set. That is a nice reason for a collector to keep the foil even if the competitive strategy isn’t their cup of tea. This is a four-promo lineup, not four guaranteed promos in a box.
When and what you get
Pokémon says select Play! Pokémon stores begin selling the Build & Battle Box October 24, 2026, before the expansion’s November 6 release. A box includes four Delta Reign booster packs, a 40-card ready-to-play deck, and one of the four foil promos. Check the official event locator for a participating local store; local stock and event details can differ.
Collector take
Prerelease is a fun way to meet a set across a table instead of staring at a product page. If you’re chasing a specific promo, don’t assume one box gets it. Trading at the event may be the saner path. The artwork and play value are real; a future resale price is not something this reveal establishes.
