One Piece Card Game / Booster Box

Romance Dawn 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.
  • market.printing: Booster Box is kept separate by exact TCGCSV sealed-product identity; the Bandai page does not document that marketplace wave distinction.
  • 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.
  • Assumption-only 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. Bandai does not publish this exact OP-01 English game-card slot recipe and no qualifying English sample establishes it. The English wrapper contains those 12 game cards plus one separate DON!! card, and the booster box additionally includes one publisher-documented Box Topper drawn from six exact English parallel cards.
  • Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
  • Bandai states that every English OP-01 booster box includes one randomly selected parallel Box Topper from six types. That fixed English bonus is retained outside the Japanese-proxy pack slots and the six exact English Box Topper SKUs receive equal weight because Bandai does not publish individual selection weights.
  • English OP-01 packs contain 12 game cards plus one separate DON!! card. The 12-card wrapper label therefore remains the game-card count, while embedded pack EV includes all 13 value-bearing cards.
  • The OP-01 DON!! branch is modeled as 23 Film RED DON!! cards plus one Manga DON!! per 24-pack box. The pack-plus-DON!! composition and the two exact English identities are documented; the one-parallel-per-box split is a community-observed first-order assumption rather than a publisher factory guarantee.
  • The displayed OP-01 box contains 313 modeled physical cards: 288 booster game cards, 24 DON!! cards, and one Box Topper. Box EV includes all 313 cards; embedded pack EV includes the 12 game cards plus the average DON!! card and excludes only the box-only topper.
  • The 7 Common / 3 Uncommon / guaranteed Rare / Rare-or-higher recipe and its 15/4/4/1 rarity split are an owner-approved Japanese-proxy prior, not a publisher-supported OP-01 English collation guarantee.
  • OP-01 keeps one public calculator because its English card pool and collation model are shared. The blue-bottom and white-bottom boxes remain separate sealed-price identities and do not create duplicate calculator routes.
  • 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, parallel, and promotional cards
  • Cards outside the supported ordinary recipe

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.

Pack & Booster Box EV

Pack and per-product Low, Mid, and High expected value ranges from one recalculation. Each physical unit is simulated separately. Fractional display-rate slots are coupled as needed to keep the full pack card count and preserve expected slot weights; factory pack correlations remain an approximation.

Modeled ROI vs entered cost------

booster boxes: 0 · Price/booster box: $0.00 · Total cost: $0.00

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.
