EX Boosters are designed to focus more on "strengthening specific themes" than regular sets, and are expected to improve existing decks and change the environment through the addition of new mechanics.

Main features of EB-04

1. Recording specifically for the Egghead arc.

This set includes numerous characters and events centered around the Egghead arc of the story, and features plenty of synergies based on the "Egghead" trait.
"Jewelry Bonney," "Vegapunk," "CP0," "The Navy," and "Emperor Kaido" are among the new cards related to Egg Head that will be released in multiple colors, greatly expanding the possibilities for deck building.

2. Support suite to strengthen existing leaders

The official product description states that "many cards that strengthen various leaders will be released," and it's not a set dedicated to a single leader, but rather a set where enhancements are widely distributed across red, green, purple, black, and yellow.
This pack contains many cards that are specifically suited to existing decks such as Straw Hat, Bonney, Navy, and CP decks, and even just 1-2 boxes can be used to directly improve deck construction and adjustments.

3. The emergence of the new leader, "Jewelry Bonney"

The new leader, Jewelry Bonney, is a two-color leader (red/yellow) with life manipulation and power-reducing mechanics centered around the characteristics "Egghead" and "Bonney Pirates".
The effects are "During your opponent's turn, if you have 1 or fewer life points, gain +2000 power" and "During the main phase, reduce the power of one of your opponent's characters by 1000, and if you have 2 or more life points, add 1 life point to your hand." The appeal of this card lies in its strong mid-to-late game plan, which involves actively reducing your opponent's life points while making use of Bonnie and events.

Notable and Popular Card Candidates

*Since market prices and ratings tend to fluctuate before and after release, this article is structured to focus on "cards with high performance and demand that are likely to receive high ratings" for SEO purposes.

1. Leader: Jewelry Bonney (Red/Yellow)

When you have one or fewer life points, its power increases to the equivalent of 7000, making it strong for late-game pressure and resilience, and it pairs well with control-oriented game plans.
Because it can activate by reducing the opponent's character's power by 1000 while converting life points into cards in hand, it is expected to be an engine that enhances the overall stability of the deck, such as by helping to search for Egghead/Straw Hat Pirates related cards and fulfilling event conditions.

2. Character: Jewelry Bonney (Red)

When it enters the field, it has a search effect that allows you to look at the top four cards of your deck and add one card with the "Egghead" or "Straw Hat Pirates" trait (other than "Jewelry Bonney") to your hand.
With a cost of 1, 2000 power, and a 1000 counter, plus easy access to key parts of the deck, this card is likely to be in high demand as it significantly boosts the stability of Bonney Leader and Straw Hat decks.

3. Event: Distorted Future (Red)

The main effect is "If you have 2 or fewer life points, reduce one of your opponent's characters by 3000," and the counter effect is "Increase your leader's power by 3000," so it's designed to turn having low life points into an advantage in both offense and defense.
Because it synergizes well with Bonnie Leader's life manipulation, it's attracting attention as a staple event candidate for red Bonnie decks.

4. Character: Megalo (Green)

It costs 4, has 4000 power, and 2000 counters, and when it enters the battlefield, it can rest itself to KO one of your opponent's rested characters with 8000 power or less, giving it removal capabilities.
In green decks, it's a valuable mid-cost removal option and is often valued as a card that can disrupt the opponent's tempo. It tends to become particularly popular in environments that heavily utilize mid-to-large units.

5. Character: Kaido (Purple)

It costs 7 and has 8000 power, and in its main phase, by resting 6 of your Don!! cards, it has a high-impact effect that allows you to give one of your "Kaido" cards +3000 power and rest one of your opponent's characters.
With its counter effect, it can reduce the leader's power by 1 while boosting it by 4000, making it a viable option as both a finisher and defensive card in purple Kaido-type decks. It is expected to appeal to both collectors and players.

6. Black-themed CP/Navy cards (Alpha/Doll, etc.)

"Alpha" has the effect of placing the top 3 cards of your deck into the trash when it enters the field, and reducing the cost of one of your opponent's characters by 1, making it a strong starting point for CP deck mechanics that refer to the trash.
"Doll" is a cost 2 blocker that also increases the cost of your Navy characters by +2 during your opponent's turn, making it a noteworthy meta card that disrupts the defense and calculations of Black Navy decks.

7. Yellow Egg Head Large Character

This yellow character, costing 8 and with 7000 power, has the restriction that it cannot attack unless there is a character with an original power of 12000 or more on the field. However, when triggered, it reduces the power of all opposing characters by 3000, and if the opponent's life is 0, it can be played as is, giving it a powerful ability to turn the tide of the game.
As a card that fills the gap in yellow decks—one that can "turn the tide of the game in one go while also developing your own board"—this card, though dependent on trigger luck, is likely to become popular.
