One Piece Card Game / Booster Box
Pillars of Strength 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.

Best Evidence — Japanese collation proxy
Evidence
This calculator is based on Best Evidence — Japanese collation proxy reviewed September 3, 2026.

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 2026-09-03: 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 pack proxy: 7 Common, 3 Uncommon, 1 guaranteed Rare, and 1 Rare-or-higher slot weighted 15/24 Rare, 4/24 Leader, 4/24 Super Rare, and 1/24 Secret Rare.
- Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
- Bandai's exact English OP-03 roster totals 127 listed types: 45 Common, 32 Uncommon, 26 Rare, 8 Leader, 10 Super Rare, 2 Secret Rare, and 4 Special cards. The four exact TCGplayer Wanted Poster rows are those unsupported Special chase cards and are removed before drawing; they are not misclassified as ordinary Super Rares.
- Bandai's OP-03 roster does not list an ordinary DON!! card. The exact English TCGplayer group contains one alternate-art DON!! SKU; it is chase-excluded and contributes no EV. The proxy still draws every disclosed pack position from retained ordinary pools, so the excluded DON!! outcome never survives as a zero-EV occupied card.
- The reviewed Bandai OP-03 product page documents no fixed Box Topper or other display-only card bonus. None is added: the modeled booster box is exactly 24 twelve-card packs, or 288 cards.
- No-chase redraw policy approved 2026-09-03: 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 DON!! cards
- Alternate-art, parallel, and promotional cards
- Cards outside the supported ordinary recipe
- Special and Wanted Poster 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.
