Experience the excitement of the latest Mega Evolution - Phantasmal Flames Build & Battle Box Early - Pokémon TCG Prerelease
The brand-new Pokémon Trading Card Game expansion, Mega Evolution—Phantasmal Flames, launches globally on 14 November 2025. But keen fans won’t have to wait that long. Beginning 1 November 2025, select game stores across the UK and worldwide will offer the Mega Evolution—Phantasmal Flames Build & Battle Box as part of official Pokémon TCG Prerelease events.
This is your exclusive opportunity to preview the cards, test new strategies, and take part in thrilling early battles using the upcoming expansion.
To find your nearest Prerelease event, visit the official Pokémon website and use the Play! Pokémon Event Locator.
What Is the Mega Evolution - Phantasmal Flames Build & Battle Box?
The Pokémon TCG Build & Battle Box is designed for the Prerelease format, allowing players to jump straight into fast-paced matches with a preconstructed 40-card deck. Inside, you’ll find:
A 40-card ready-to-play Pokémon TCG deck
4 Mega Evolution—Phantasmal Flames booster packs
1 of 4 exclusive foil promo cards from the new expansion
These boxes offer a perfect introduction to the Pokémon card game, particularly for new players looking to learn the game in a fun and accessible format. For experienced Trainers, it’s a great chance to explore fresh strategies and test out powerful new cards from the upcoming set.
What Makes Prerelease Events Special?
Pokémon TCG Prerelease events use a unique format. Players build a 40-card deck from the Build & Battle Box contents and set aside four Prize cards instead of the usual six. This results in quicker games that are perfect for casual play, yet still highly competitive.
Because the card pool is limited and based on what’s pulled from your box, every deck feels unique—making deck-building creativity just as important as battle strategy.
Promo Cards in Mega Evolution—Phantasmal Flames
Each Build & Battle Box includes one of four exclusive foil promo cards. Here’s a closer look at each featured Pokémon and how they might impact your matches during the Prerelease event.
Ceruledge – High Damage, High Risk

Ceruledge packs a punch with its Infernal Slash attack, dealing 220 damage if you discard four Basic Fire Energy from your hand. It’s a powerful card in the Prerelease format, capable of knocking out many opposing Pokémon in a single blow.
To support Ceruledge, look for the Firebreather Supporter card, which helps you load your hand with Fire Energy. The Blowtorch Item card can also enhance your deck by discarding Energy to remove key Stadium and Pokémon Tool cards from play.
Zacian – Early Game Aggression

In the standard format, Zacian’s Limit Break ability activates late in the game—but in Prerelease, it triggers as soon as your opponent takes their first Prize card. With 140 damage, Zacian quickly becomes a threat.
Before going all-in with Zacian, consider using Alcremie, found in your 40-card deck, which has a solid early-game attack in Sweet Circle. Use Wondrous Patch to recycle Psychic Energy and prepare Zacian for a decisive strike.
Flygon – Deck Disruption and Control

Flygon features the Sandy Flapping Ability, which discards two cards from your opponent’s deck when it evolves and again when it’s Knocked Out. In a 40-card Prerelease deck, this can be a game-ending disruption tool.
While evolving from Trapinch to Vibrava to Flygon, you can slow your opponent down with Gligar and Gliscor—sturdy Pokémon that buy you time while you set up Flygon’s devastating impact.
Toxtricity – Energy Acceleration with a Twist

Toxtricity’s Sinister Surge Ability may harm your own Pokémon, but the trade-off is well worth it—extra Darkness Energy each turn. This lets you power up Toxtricity’s own Gentle Slap, or better yet, set the stage for Krookodile’s Hammer In attack.
In your Build & Battle deck, you’ll find tools like Rare Candy and Grimsley’s Move, which help evolve Pokémon quickly. With luck, you can bring out Krookodile fast and start swinging for heavy damage.
Look Out for Bonus Pulls
While your deck is preconstructed, your four booster packs offer the chance to pull even more powerful cards. If you manage to open Carvanha and Mega Sharpedo ex, you’ll gain another high-damage Darkness-type attacker to pair with Toxtricity’s energy boost.
Where to Buy and Play
