1. Unbeatable “Two-Sets-in-One” Value

View on

Bandai has cleverly combined the core OP-15 cards with select high-impact entries (yellow, red, and black) from EB-04, delivering a dense, powerful product. Instead of chasing separate releases, you get access to premium staples from two Japanese waves in a single set. This makes it one of the smartest and most budget-friendly ways to upgrade your collection, especially with the global shift to simultaneous releases kicking in this August.

2. Seven Fresh Leaders to Explore

The set introduces a diverse lineup of seven new Leaders, catering to various playstyles from explosive aggression to patient control. Key highlights include:

Purple Enel — A top-tier powerhouse that thrives even with a restricted 6-card DON!! deck, leveraging Skypiea dominance.

Black Green Brook — The Straw Hat musician steps up as a Leader for the first time, built around a signature “mill and revive” engine.

Red Green Krieg — Brings a fresh twist by letting you “steal” rested DON!! from your opponent to weaken their board.

Blue Rebecca & Red Yellow Lucy — Perfect for Dressrosa fans, offering strong deck filtering and event-triggered draw power.

3. Rotation-Proof Powerhouses

With the Block Number System and set rotation starting April 1, 2026, sending Block 1 cards (OP-01 to OP-04 and early starters) out of Standard, this set arrives at the perfect time to plug critical gaps. Expect cards like the new Borsalino (from EB-04) and Enel Super Rare (OP15-118) to quickly become yellow format essentials. Investing here isn’t just about flashy new options; it’s about locking in the core “glue” cards that will define competitive decks in the post-rotation era.

4. Double the Manga Rare Excitement

Collectors and chase-card hunters will love this: spanning two Japanese sets means two Manga Rares, Enel and Koby. Enel, as the iconic Skypiea villain and a meta-relevant card, is already shaping up to be one of the most coveted (and pricey) pulls ever. Add in nine stunning Special Rare (SP) cards, and the odds of landing high-value, gorgeous artwork feel significantly better than in typical sets.

5. Early Access and Exclusive Pre-Release Perks
