遺跡をこえて… Secret Rare Pull Rate — 8.00% per pack (1 in 13)

8.00% of 遺跡をこえて… booster packs contain a Secret Rare card — roughly 1 in 13 packs. 遺跡をこえて… ships 1 Secret Rare card in the pool, so the chance of pulling any specific Secret Rare is 0.0800 (≈1 in 13). These percentages come from PackRip's own rate table (the same constants the simulator runs on) — they are a model of the product, not a measurement of it. The Pokemon Company has never published pull rates.
遺跡をこえて… Secret Rare pull-rate methodology
| Formula | Tier odds = 8.00% per pack; per-card odds = tier odds ÷ 1 Secret Rare card = 1 in 13. |
|---|---|
| Assumptions | One independent rare-slot roll per pack; uniform selection within the tier; no pity timers, box mapping, short-print correction, or edition/condition split. |
| Data source | Set checklist and rarity labels from the bundled Pokemon TCG API catalog; tier rates from rareSlotRates(), mirrored from the live pack opener. |
| Update cadence | Regenerated by prerender whenever set metadata, catalog data, or pull-rate constants change. |
| Limitations | This is a theoretical per-pack rate. Real sealed product can show print-run variance, collation quirks, and market-specific edition differences. |

How the 8.00% rate is computed
Every 遺跡をこえて… booster pack rolls one rare-slot card (plus uncommons, commons, and energy in fixed slots). The rare slot is itself a weighted random draw across 3 tiers — Rare, Holo Rare, Secret Rare, and the era's other chase rarities. The Secret Rare tier captures 8.00% of those rare-slot draws (= 8.00 packs out of every 100). Within the Secret Rare tier, all 1 card share the slot uniformly, so per-card odds are 8.00% ÷ 1 = 0.0800 = 1 in 13.
This is the same math PackRip's live 遺跡をこえて… simulator uses to roll packs — open as many as you want for free, watch the empirical hit rate converge to the theoretical 8.00% over a large enough sample. Source code lives in src/utils/packGenerator.ts and the per-rarity drift is build-time-asserted against the published rates so the simulator and this landing page can never disagree.
Cumulative probability — how many packs to hit Secret Rare
Secret Rare pulls follow a geometric distribution with per-pack rate 0.080000. The expected number of packs until your first Secret Rare hit is 13; at 95% confidence you'll have one within 36 packs. Most experienced openers crack a sealed booster box (36 packs) and hit Secret Rare with probability 95.0% — so the average box yields just over 2.9 Secret Rare pulls.
