Crystal Guardians Pokémon-ex Pull Rate — 21.70% per pack (1 in 5)
21.70% of Crystal Guardians booster packs contain a Pokémon-ex card — roughly 1 in 5 packs. Crystal Guardians ships 10 Pokémon-ex cards in the pool, so the chance of pulling any specific Pokémon-ex is 0.0217 (≈1 in 46). 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.
Crystal Guardians Pokémon-ex pull-rate methodology
| Formula | Tier odds = 21.70% per pack; per-card odds = tier odds ÷ 10 Pokémon-ex cards = 1 in 46. |
|---|---|
| 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 21.70% rate is computed
Every Crystal Guardians 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 4 tiers — Rare, Holo Rare, Pokémon-ex, and the era's other chase rarities. The Pokémon-ex tier captures 21.70% of those rare-slot draws (= 21.70 packs out of every 100). Within the Pokémon-ex tier, all 10 cards share the slot uniformly, so per-card odds are 21.70% ÷ 10 = 0.0217 = 1 in 46.
This is the same math PackRip's live Crystal Guardians simulator uses to roll packs — open as many as you want for free, watch the empirical hit rate converge to the theoretical 21.70% 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 Pokémon-ex
Pokémon-ex pulls follow a geometric distribution with per-pack rate 0.217000. The expected number of packs until your first Pokémon-ex hit is 5; at 95% confidence you'll have one within 13 packs. Most experienced openers crack a sealed booster box (36 packs) and hit Pokémon-ex with probability 100.0% — so the average box yields just over 7.8 Pokémon-ex pulls.
