One Piece ST-21 GEAR5 Starter Deck EX: Aggression, Sleeves, and Separating Play Value from Extras
GEAR5 packages a Luffy deck with collector-friendly extras. Work out what you want to play before allowing sleeves and a bonus pack to make the decision for you.
What this product is
ST-21 is GEAR5 Starter Deck EX, released in English on March 14, 2025. A constructed 51-card deck, ten DON!! cards, a playsheet, seventy sleeves, and a three-card bonus pack.
The 51-card deck count includes its Leader and fifty main-deck cards. The DON!! cards are separate. One complete starter supplies one player’s deck; a two-person learning match needs another complete setup. Random bonus cards, where included, are separate from the fixed learning deck.
How to approach the deck
Bandai describes an aggressive DON!!-based deck led by a Gear 5 Luffy. Its package includes the constructed deck, DON!!, a playsheet, seventy sleeves, and a three-card bonus pack. Start by evaluating whether the Leader’s actual decisions appeal to you. Then value the extras separately: sleeves can be useful immediately, while a random alternate presentation does not solve a specific deck-building need.
A useful teaching exercise
Write a realistic closing turn using the actual cards in your hand. Identify which attack requires a DON!! attachment and which development play you must skip to afford it. Have a teaching opponent choose the most efficient defense. Replay after holding one resource back and compare whether the attack pressure still justifies the commitment.
Who should compare it?
A sensible option to compare for Gear 5 fans who want a complete themed package. It is not automatically the cheapest route to a first match.
One mistake to avoid
The EX label describes a product package, not a guarantee that it beats every ordinary starter or meets a particular event’s card-pool rules.
Before buying or upgrading
Match the exact product code and English language in the selected offer. Compare a sealed package with any deck-only resale by the contents actually included. If you want a particular upgrade, price the eligible singles before opening boosters in pursuit of it. Use the current event rules and restriction list for organized play; an old release-date legality note is not a current eligibility guarantee.
