Archazia's Island 24-Pack Booster Display EV Calculator

Publisher + empirical collation

Evidence

This calculator is based on Publisher + empirical collation reviewed July 23, 2026.

Empirical sample

Sample unit

Pack

Sample size

1056

Observed

Not reported by the source

Region

Halifax, Nova Scotia, Canada (English-language retail product)

Case correlations

Not preserved

Method

Empirical collation from The Deck Box Halifax: 44 booster boxes / 1056 packs were opened for singles and card-level counts were published. The model preserves aggregate Normal and Cold Foil R/SR/L counts exactly, removes disclosed premium families, and does not infer uncounted Common/Uncommon foils. Manufacturer printing wave and actual opening interval were not disclosed.

Limitations

• Empirical collation: 1,056 packs (44 displays) from one Halifax store. Manufacturer printing wave and the actual observation interval are undisclosed. No separate dated opening post was located for this tab.
• Empirical observation start (observedFrom): undisclosed by the source.
• Empirical observation end (observedThrough): undisclosed by the source.
• Empirical sample printing wave (wave): not reported by the source.
• Empirical sample printing detail (printingDetail): not reported by the source.
• The source counted 2,121 Normal R/SR/L cards and 231 Cold Foil R/SR/L cards. Common, Uncommon, and Common/Uncommon foil observations were intentionally not counted; publisher-fixed nonfoil Common/Uncommon slots remain, while unmeasured low-rarity foils are absent rather than zero-valued outcomes.
• The tab note is copied from Azurite Sea and incorrectly says 42 boxes/1,008 packs. The Archazia card rows and every displayed per-box average independently resolve a 44-box/1,056-pack denominator. Its ordinary total is 2,121 versus 2,112 publisher slots (+9, +0.43%); raw counts are preserved.
• Expected display counts are the empirical per-pack rates multiplied by the publisher's exact 24-pack wrapper. The aggregate sample does not preserve within-display or case correlation, so only EV—not hit-count variance or guarantees—is approved.
• Modeling policy approved 2026-07-23: 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.
• No-chase redraw policy approved 2026-07-23: 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.
