Extra Booster: One Piece Heroines Edition pull rates

12 cards per booster, 24 packs per box and 12 boxes per case. Reviewed 2026-11-05 (UTC).

Every individual-card number is an educated estimate, not a measured or official probability. Equal selection within each reviewed printing tier is assumed. Small community reports are context, not proof of a fixed box/case quota.

Extra Booster model: 9 Common slots, about 1 ordinary Leader and 6 SR per 24-pack box. Rarity frequencies are educated allocations; EB01 and EB02 use different alternate-art assumptions.

Chase priors: any Manga/Super Alternate Art averages one in four cases; gold SP or signed card one in twenty; super Leader one in ten. These are especially uncertain analogues, split across the listed tier. Zero observed hits is never treated as impossibility.

Promotional inserts, bonus packs and box toppers are excluded from ordinary booster odds. A card number appearing in multiple sets does not make the printings interchangeable.

EB03 SP identities use a blended 2-per-case tier estimate. Special multi-hit packs can cluster these cards; no sealed-box or God-pack guarantee is implied.

Sources: Bandai English product catalogue (card types, not odds); English OP01 community opening report (secondhand, six cases); OPTCG Quotas EB03 (unofficial community structure; no counted sample). These sources describe product contents or community experience; none measures every exact card’s probability. The full evidence ledger is retained for review.

The model uses assumed tier frequencies and fixed reviewed card pools. It does not infer rarity from price, and an absent price does not remove a card from its pool. A conditional estimate does not confirm that the exact printing appears in boosters.
