Ascended Heroes Special Illustration Rare pull-rate methodology

How PackRip computes this page
Formula	Tier odds = 2.80% per pack; per-card odds = tier odds ÷ 22 Special Illustration Rare cards = 1 in 786.
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 2.80% rate is computed

Every Ascended Heroes 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, Special Illustration Rare, and the era's other chase rarities. The Special Illustration Rare tier captures 2.80% of those rare-slot draws (= 2.80 packs out of every 100). Within the Special Illustration Rare tier, all 22 cards share the slot uniformly, so per-card odds are 2.80% ÷ 22 = 0.0013 = 1 in 786.

This is the same math PackRip's live Ascended Heroes simulator uses to roll packs — open as many as you want for free, watch the empirical hit rate converge to the theoretical 2.80% 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 Special Illustration Rare
