Limitations

• The immutable product revision does not publish a qualifying English sealed-case rarity breakdown.
• Publisher-supported fixed-bonus treatment: Each sealed English display includes one publisher-shown Box Purchase Bonus Pack containing 2 cards selected from 6 special-finish alternate-art types. The six exact English TCGplayer Box Topper identities are modeled as two independent equal-weight box-only draws, separately from the 24 boosters; no no-duplicate guarantee is inferred.
• The display identity and 24-pack wrapper are exact, but display/case guarantees and covariance are not modeled.
• 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 13/24 Rare, 6/24 Super Rare, 2/24 Ultimate Rare, and 3/24 Secret Rare. EX12's product-specific Japanese evidence and direct English opening report supply the six regular Super Rare and two regular Ultimate Rare counts; its three parallel-or-Secret Rare hit positions are conditioned on retained regular-art Secret Rares after chase removal.
• Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
• The reviewed Japanese EX12 estimate reports about 3 regular Super Rares, 0.5–1 regular Ultimate Rare, and 0.5 regular Secret Rare per 24-pack box alongside multiple parallel branches. A direct English case-opening report identifies 6 regular Super Rares, 2 regular Ultimate Rares, 2 alternate arts, and 1 alternate-art-or-Secret-Rare hit per 24-pack display.
• All three exact English regular-art Ultimate Rare identities are retained. The three unsupported parallel hit positions are removed before drawing and conditioned onto the two regular-art Secret Rares, producing a retained 13 Rare, 6 Super Rare, 2 Ultimate Rare, and 3 Secret Rare upgrade mix. This is a no-chase marginal estimate, not a factory guarantee.
• EX12's 42 exact English Limited Foil Common and Uncommon SKUs are low-pull in-pack outcomes, not ordinary bulk finishes. One Limited Foil Common and one Limited Foil Uncommon replace matching ordinary positions per display; the 24 boosters therefore remain exactly 288 cards.
• Bandai states that buying an EX12 box supplies alternate-art cards with a special finish, and the reviewed promotion-pack checklist identifies 2 cards per pack from 6 types. The exact English Box Topper pool contains Kakamon, Gammamon, ToyAgumon, Wankomon, Jellymon, and Angoramon; two independent equal-weight box-only draws are included because no unequal weights or no-duplicate rule are published.
• The displayed single-pack EV includes the two in-pack Limited Foil replacement rates but excludes the two box-only promotion cards. The bonus cards contribute only to display EV, for 290 modeled physical cards per display.
• Unrelated alternate arts, SP cards, Rare Pull cards, event variants, and unpriced tokens remain excluded before drawing. The six Box Topper SKUs are retained only in their publisher-supported fixed bonus pool.
• 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.
