What is the Pokémon-ex pull rate in Boundaries Crossed?

16.70% per booster pack — roughly 1 in 6 Boundaries Crossed packs contains a Pokémon-ex card. Boundaries Crossed ships 6 Pokémon-ex cards in its pool, so per-card odds are ≈1 in 36. The rate is PackRip's own published constant for that tier, identical in the simulator and in this dataset. It is not derived from real print-run data, which has never been published.

How many Boundaries Crossed packs to pull a Pokémon-ex?

On average 6 packs to hit your first Pokémon-ex — that's the expected value of a geometric distribution with parameter p=0.167000. At 95% confidence you'll have one within 17 packs. A sealed 36-pack booster box yields a Pokémon-ex with probability 99.9%.

Boundaries Crossed Pokémon-ex Pull Rate — 16.70% per pack (1 in 6)

Celebi-EX — Boundaries Crossed

16.70% of Boundaries Crossed booster packs contain a Pokémon-ex card — roughly 1 in 6 packs. Boundaries Crossed ships 6 Pokémon-ex cards in the pool, so the chance of pulling any specific Pokémon-ex is 0.0278 (≈1 in 36). 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.

Boundaries Crossed Pokémon-ex pull-rate methodology

How PackRip computes this page
Formula	Tier odds = 16.70% per pack; per-card odds = tier odds ÷ 6 Pokémon-ex cards = 1 in 36.
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 16.70% rate is computed

Every Boundaries Crossed 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 6 tiers — Rare, Holo Rare, Pokémon-ex, and the era's other chase rarities. The Pokémon-ex tier captures 16.70% of those rare-slot draws (= 16.70 packs out of every 100). Within the Pokémon-ex tier, all 6 cards share the slot uniformly, so per-card odds are 16.70% ÷ 6 = 0.0278 = 1 in 36.

This is the same math PackRip's live Boundaries Crossed simulator uses to roll packs — open as many as you want for free, watch the empirical hit rate converge to the theoretical 16.70% 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 0.167000. The expected number of packs until your first Pokémon-ex hit is 6; at 95% confidence you'll have one within 17 packs. Most experienced openers crack a sealed booster box (36 packs) and hit Pokémon-ex with probability 99.9% — so the average box yields just over 6.0 Pokémon-ex pulls.
