Prerelease Guide

A prerelease is your first opportunity to play with cards from an upcoming set before it becomes legal in standard tournament play. Prereleases use the Build & Battle format, which tests your ability to construct a functional deck from a sealed pool under time pressure.

What to Expect

Prereleases are held the weekend before a new set's official release date. They are hosted at local game stores and official leagues. The atmosphere is more relaxed than a competitive tournament — many attendees are casual players excited to open new cards.

Format: Build & Battle. You receive a prerelease kit containing a fixed number of booster packs and a promo card. You build a 40-card deck from the cards you open and play a short Swiss tournament.

Duration: Typically 3-4 hours, including deck construction time and 3-4 rounds of play.

Competition Level: Mixed. Prereleases attract casual players, collectors, and competitive players testing the new set. Expect a wide range of deck quality.

The Build & Battle Kit

Each prerelease kit (Build & Battle Box) contains:

A 40-card ready-to-play deck, including 1 of 4 alternate-art promo cards
4 booster packs from the new set to supplement your deck
Basic Energy cards provided by the store or organizer

You open your booster packs, review your ready-to-play deck, and modify it using the cards you opened. The final deck must be exactly 40 cards. You may swap cards from your booster packs into the deck and use the basic Energy provided by the organizer.

Building Your Deck

Deck construction at a prerelease follows different principles than constructed play. You do not have the luxury of a refined 60-card list. You must work with what you open.

Step 1: Sort by Type

Lay out all your cards grouped by Pokémon type. Identify which type has the strongest Pokémon and the most supporting cards. Your deck will typically center around one or two types.

Step 2: Identify Your Attacker

Choose 2-3 Pokémon that can serve as your primary attackers. Look for:

Reasonable attack Energy costs
Damage output that can KO basic Pokémon in 2-3 hits
Abilities that provide card advantage or board control

Do not build around a single powerful attacker if it requires 4+ Energy to activate. Consistency wins at prereleases.

Step 3: Fill Out Your Line

A functional prerelease deck needs:

6-10 Pokémon total, including your attackers and basic Pokémon for the bench
8-12 Trainer cards — prioritize draw supporters, search cards, and switches
10-14 Energy cards — enough to power your attackers without flooding your hand

The exact ratios depend on your pool. If you opened multiple draw supporters, you can run fewer Energy. If your attackers are Energy-heavy, increase your Energy count.

Step 4: Check Your Curve

Before you sleeve your deck, verify that you can execute your game plan:

Can you attack by turn 2 or 3?
Do you have enough draw to find your pieces?
Do you have answers for your opponent's likely strategy?

If the answer to any of these is no, adjust your deck before the tournament starts.

Strategy Note

Strategy Note: Do not overthink your prerelease deck. A simple, consistent deck that attacks early will beat a complex deck that cannot execute. Prioritize function over ambition.

During the Tournament

Prerelease rounds are short. Play aggressively, manage your resources, and do not give up on games that look lost. Your opponent is working with a random pool too — their deck may have the same weaknesses as yours.

Pay attention to what other players are running. If a particular Pokémon or strategy is dominating, note it for future constructed play. Prereleases are an early meta preview.

After the Prerelease

The set is now legal for constructed play. Take what you learned — which cards performed well, which strategies were strong — and apply it to your 60-card deck building. The prerelease meta is not the constructed meta, but it gives you a head start on understanding the new set.
