Limitations

• The immutable product revision does not publish a qualifying English sealed-case rarity breakdown.
• 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 16/24 Rare, 7/24 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.
• The reviewed Japanese BT21 estimate reports about 7 regular Super Rares and 0.5 regular Secret Rares per 24-pack box alongside multiple premium branches. After removing those premium branches, the 16 Rare, 7 Super Rare, and 1 Secret Rare retained-slot recipe is a conditional no-chase normalization, not a claim that raw sealed boxes contain one regular Secret Rare.
• The English display includes two fixed bonuses outside the 24 booster packs. Bandai states that the Illustration Celebration Pack contains 2 cards from 6 and the Limited Card Pack contains 7 cards from 10 types; the reviewed English Limited Card Pack checklist identifies those seven as all 6 LM-039 through LM-044 promos plus 1 random alternate art from 4. These 9 bonus cards are included, for 297 modeled cards per display.
• The publisher does not state individual selection weights for the two Illustration Celebration cards or the Limited Card Pack alternate art. Each exact English card in the applicable bonus pool therefore receives equal positive weight; no no-duplicate guarantee is inferred for the Illustration Celebration Pack.
• These rate-supported English box bonuses are not chase-excluded. Unrelated promotional cards and unsupported alternate-art, Rare Pull, SP, signed, and serialized branches remain absent before the draw.
• The displayed single-pack EV uses only the 12 booster-pack cards; the 9 box-only bonus cards contribute to display EV but are not prorated into loose-pack EV.
• No within-display booster correlation or case guarantee is modeled; the two publisher-stated box bonuses are modeled separately from the 24 booster packs.
• 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.
