The Set Inside
Bandai’s official OP-15 page introduces six Leaders: Krieg, Lucy, Brook, Rebecca, Enel and Monkey D. Luffy. Luffy and Enel are the Secret Rares, Enel is the Super Parallel and there are two event parallel cards. Every box is randomly assorted, so a case gives you more chances across the list without any card being guaranteed.
Who Buys a Case?
Cases are popular with group breaks, local play groups that split boxes between members, and collectors who want to open some boxes and keep others sealed. Opening box by box and recording what you find makes it easy to see which cards are still missing from your Skypiea binder.
Splitting a case with friends? Agree beforehand how the boxes will be shared, and note each box’s standout cards as you go. Any boxes you keep back store easily upright in a cool, dry room.
