One Piece Card Game / Booster Box
Emperors in the New World Booster Box EV Calculator
Estimate this physical product's no-chase expected value with a product-, region-, language-, and printing-specific model, then compare the modeled range with your entered cost. Estimated ROI is a planning metric, not a guaranteed return.

Limitations
- collation.cardsPerPack and collation.packsPerProduct: the product uses 12 cards per pack and 24 packs per English booster box; those physical wrapper counts do not establish rarity-slot probabilities.
- collation.caseStructure: box-level hit counts and display/case correlations are unresolved for the exact English North America printing.
- evidence.sample: null because no reviewed observation provides a complete, attributable sample with exact unit, size, method, North America printing, and observation interval.
- pricing.coverage: exact TCGCSV identity is known, but modeled row and expected-mass coverage have not been measured.
- Modeling policy approved 2026-09-04: every supported ordinary card in the same slot, rarity, treatment, and finish pool receives one equal positive selection weight. This is a transparent modeling assumption where the publisher or empirical sample gives pool odds but not card-level sheet weights.
- Best Evidence — Japanese collation proxy: exact English wrapper and card-price identities are combined with an owner-approved Japanese-product collation proxy because a complete English rate ledger is not published. This is an estimate, not a factory guarantee.
- Only booster-pack slot counts and rarity probabilities are proxied. Card identities, treatments, TCGplayer Low prices, sealed-product identity, language, region, release date, and any explicitly modeled fixed bonus come from the exact English release.
- The proxy is first-order and product-family-specific. No display or case correlation is inherited, and no target is used as a donor for another target.
- Within each retained English rarity/treatment pool, exact positively priced card SKUs use equal positive weight where publisher sheet weights are unavailable.
- Per 24-pack English box proxy: 170 Common, 60 Uncommon, 39 Rare, 8 Leader, 7 Super Rare, 2 retained Secret Rare, and 2 parallel DON!! cards fill exactly 288 physical positions. The OP-09 two-box Japanese ledger is scaled from six to twelve cards per pack; its single observed alternate-art position is conditioned on regular Secret Rares before drawing. This small-sample marginal is an English adaptation assumption, not a box guarantee.
- Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
- The reviewed OP-09 opening covers two Japanese boxes (48 six-card packs): 170 C, 60 UC, 39 R, 8 L, 7 SR, 1 regular SEC, 1 parallel SR, and 2 DON!!. No exact English rarity rates, per-pack sequence, or case correlations are established by that sample. The high-hit redraw from the excluded parallel to regular SEC is a disclosed no-chase modeling assumption.
- The English OP-09 catalog has 130 game-card types plus one DON!! type: 119 ordinary L/C/UC/R/SR/SEC identities, ten SP cards (including four Wanted Posters), and one Treasure Rare. All SP, Wanted Poster, Manga/Gold Super Parallel, Treasure Rare, and ordinary alternate-art/parallel chase SKUs are excluded before drawing. Exact English regular-art Gol.D.Roger and Monkey.D.Luffy Secret Rares remain eligible; each retained English rarity pool uses equal per-card weights.
- English booster DON!! product 604246 is retained at the two-per-box Japanese-ledger marginal. Its embedded pack EV includes the average 2/24 contribution, within the 288-card proxy. Double Pack Set Vol.6 DON!! products 605125 and 605126 belong to a separate product and are excluded. No box-topper or purchase promotion is added to this sealed booster-box SKU.
- The synthetic 12-card pack representation uses seven Common, two Uncommon, one guaranteed Rare, one filler slot weighted 2/24 Common, 12/24 Uncommon, 8/24 Leader and 2/24 DON!!, and one upgrade slot weighted 15/24 Rare, 7/24 Super Rare and 2/24 Secret Rare. Slot assignment and independence are adaptation assumptions; these probabilities preserve expected counts without guaranteeing a simulated box's rarity totals or DON!! count. Sift and other user filters apply only after all twelve cards are drawn.
- No-chase redraw policy approved 2026-09-04: Curio, Enchanted, alternate-art, parallel, showcase, serialized, signature, premium-rarity, promotional, and any other card or treatment without a supported pull rate are excluded. A chase hit is redrawn from the applicable supported ordinary pool, so excluded cards occupy no modeled outcome.
- Simulation ordering is draw the complete disclosed no-chase product first, record that draw, and only then apply Sift or another user filter. Sift never changes or backfills the completed modeled draw.

No-chase model
Chase Exclusions
Excluded chase families are removed from the model entirely. They are never retained as zero-EV occupied outcomes. Each affected physical position is instead filled from its disclosed supported ordinary pool before the product draw is completed.
- Alternate-art, parallel, and promotional cards
- Separate-product Double Pack DON!! cards
- Showcase, serialized, signature, and hyperspace cards
- Special and Wanted Poster cards
- Special cards (SP)
- Treasure Rare cards
- Unpriced or incomplete-metadata special cards
Model assumptions & evidence
Simulation order: complete product contents are drawn first. Included-pool controls and optional Sift are applied only after the draw, and filtered outcomes are never replaced or backfilled.

All modeled slots are resolved before pool toggles or Sift score the opened product. This ordering prevents replacement draws from inflating EV.

How is estimated ROI calculated? It equals modeled profit divided by the entered product cost. Modeled profit subtracts that product cost, selected seller fees, and any entered order or shipping costs from the modeled resale value. It is not a guaranteed return; pull variance, market price changes, taxes, and other unmodeled selling costs can change actual resale results.

The simulator draws the full physical product first, then applies disabled pools and optional Sift. Filtered outcomes occupy their actual slots and are never backfilled.
