Raichu ex chase methodology

How PackRip computes this page
FormulaSpecific-card odds = Pokémon-ex tier rate (24.70%) ÷ 7 cards; confidence bands solve 1 - (1 - p)^N.
AssumptionsIndependent pack rolls, uniform selection within the rarity tier, no pity timers, no box mapping, no first-edition/condition split, no duplicate protection.
Data sourceCard identity and rarity from the bundled Pokemon TCG API catalog; pull-rate constants from the live simulator; market price from the bundled TCGplayer snapshot.
Update cadenceRegenerated by prerender; price values update when the TCGplayer snapshot is refreshed through the data pipeline.
LimitationsThe page estimates probability and raw market cost only; it does not model grading premiums, counterfeit risk, sealed-product appreciation, or individual print-run collation.

Raichu ex — Sandstorm #98

This page answers exactly one question: how many Sandstorm booster packs does it take to pull Raichu ex #98? The numbers below come from the same per-rarity pull-rate model the PackRip Sandstorm simulator runs on, mirrored from packGenerator.ts. TCGplayer pricing refreshes every build, so the buy-vs-rip verdict at the bottom reflects current market.

The math: ~1 in 28 per pack

Raichu ex sits in the Pokémon-ex rare-slot pool for Sandstorm. There are 7 Pokémon-ex cards in the Sandstorm pool, and the Pokémon-ex slot fires with probability 24.70% per pack. Since the slot is split evenly across the 7 cards in that tier, the per-pack chance of pulling this specific card is 1 in 28 — approximately 1 in 28.

Pulls are independent and identically distributed, so the number of packs until you hit Raichu ex follows a geometric distribution with parameter p = 0.035286. The expected number of packs is 1/p — that's ~29 packs on average. But "average" hides huge variance: the median pull lands faster than the mean (~20 packs at 50% confidence), and a long unlucky tail can stretch the wait dramatically. The 95% confidence band — 84 packs — is where 95% of pull-runs finish; the remaining 5% take even longer.

Concretely: if 100 collectors each opened Sandstorm packs until they pulled Raichu ex, roughly 50 of them would have it by pack 20, 95 of them would have it by pack 84, and a handful would still be chasing past that. Expected ≠ guaranteed; the geometric distribution is famously long-tailed on the right side.

Confidence bands — packs vs cumulative probability

P(pulled by N packs)Packs neededSealed cost at $5/pack
10%3 packs~$15 sealed cost
25%9 packs~$45 sealed cost
50%20 packs~$100 sealed cost
75%39 packs~$195 sealed cost
90%65 packs~$325 sealed cost
95%84 packs~$420 sealed cost
99%129 packs~$645 sealed cost

Read this table as "what fraction of openers have pulled Raichu ex by pack N?". A 25% band of 9 packs means a quarter of openers hit it inside that window; 99% means almost everyone has hit it by pack 129. The dollar column anchors the variance to real-world sealed-pack cost at $5/pack.

Cheaper to buy Raichu ex as a single?

Pack-ripping breaks even or beats singles on raw cost for Raichu ex — but you'd absorb the rest of the pack contents along the way. Most hunters still mix: rip for the experience, buy the single if RNG turns sour.

Pack-rip expected dollar cost for this specific card: ~$142 at $5 per Sandstorm pack. Compare to $219.31 for the single on TCGplayer (Unlimited / non-graded copy at current market). The single buy obviously delivers exactly this card; the pack-rip approach delivers Raichu ex plus the remaining 8 cards in every pack along the way — which is why the EV calculator at /ev/ex2 spreads the cost across the whole pack contents instead of pinning it to one card.

About Raichu ex (Sandstorm)

Raichu ex is a Pokémon-ex card from Sandstorm, the 2003 Pokémon TCG expansion. Sandstorm (2003) runs 100 cards, 92 of them Pokemon and only one Energy. Seven cards carry the ex subtype, numbered #94 to #100 — Aerodactyl, Aggron, Gardevoir, Kabutops, Raichu, Typhlosion and Wailord. Mitsuhiro Arita leads the credits with 14 illustrations and Midori Harada follows with 13. There are no Secret Rares in this set.

This specific card ranks as one of the top-3 most valuable pulls in Sandstorm by TCGplayer market value, which is part of why the chase math is what it is — high market value tends to track with rarity-tier depth, since lower pool sizes concentrate value into fewer cards. The complete top-25 Sandstorm ranking shows where Raichu ex sits relative to the rest of the chase pool.

Pull odds in context

For reference, a "1 in 28" pull is roughly comparable to a moderate chase — you should expect to crack a couple of boxes. The variance is the killer: any one pack could be the one. The simulation on PackRip's Sandstorm opener uses the same exact RNG model, so you can stress-test the wait curve without spending real money.

Strategy: optimising the Raichu ex chase

Every experienced Sandstorm hunter eventually picks one of three approaches for a specific chase card. The cheapest is the snipe: skip pack-ripping entirely, set a TCGplayer alert at or below the current $219.31 market, and wait for a motivated seller. This is the route most efficient-frontier collectors take when the chase is locked behind a deep rarity tier — and the math above shows why. The expected pack-rip cost ($142) is typically multiples of the single price, and the variance on that expectation is wide enough that a single bad streak can blow past the 95% confidence bound. The single buy is dollar-for-dollar cheaper and emotionally cheaper too — no more refreshing pack-pull videos at 3am.

The middle path is the box-rip-then-snipe: open a sealed booster box of Sandstorm (typically 36 packs for vintage sets), enjoy the experience, then if you didn't hit Raichu ex in the box, buy the single for $219.31. A 36-pack box delivers a probability of 1 − (1 − p)36 ≈ 72.6% of pulling Raichu ex at least once, where p is the per-pack hit rate of 0.035286. So a sealed box gives you roughly a 73% chance of hitting this card "for free" alongside the rest of the box contents, plus the rip experience. If you miss, you backstop by buying the single — total worst-case cost is the box price plus the single. Most rational hobbyists end here.

The expensive path is pure-rip-to-pull: keep opening packs until Raichu ex appears. The expected total cost is ~$142, but the 95th percentile pushes that to ~$420. Almost nobody who does this comes out ahead financially — but it produces the binder story, the YouTube content, and the cumulative pulls of the entire pack contents along the way. If your real goal is collecting all of Sandstorm, not just acquiring Raichu ex, the pure-rip path has an internal logic the singles path doesn't.

Variance is the entire story

Here's a concrete illustration of how wild the geometric distribution gets at low p. Consider 10 hypothetical openers all chasing Raichu ex from Sandstorm. Mathematically, you'd expect their results to cluster near the 29-pack expectation — but they won't. Roughly 5 will pull Raichu ex within the first 20 packs and feel lucky. Roughly 3 will pull between 20 and 29 packs and feel "about average". And roughly 2 will be still pulling past pack 29, with one of them potentially stretching past the 95% bound of 84. The unlucky ones will swear the simulator is rigged, the rates are wrong, or that they have terrible RNG — but the math says exactly this distribution should happen every time. The geometric distribution has no memory: each pack is an independent draw, and a 100-pack dry streak does not increase the odds of the next pack hitting.

How Raichu ex compares to the broader Sandstorm chase pool

Raichu ex sits in the Pokémon-ex tier of Sandstorm's rare-slot pool. 7 cards share this tier, and the tier itself fires roughly 24.70% of the time per pack. That means the per-pack chance of pulling any Pokémon-ex card (not just Raichu ex) is 24.70%, which makes the expected wait for any Pokémon-ex card much shorter than the wait for this specific one. Pull-rate intuition: a single chase from a 6-card tier is 6× rarer than the tier itself. The deeper the pool, the longer the chase. This is also why "wide" sets with many chase cards in a single tier feel grindier per individual card despite the tier hit rate being identical — a thicker tier dilutes each card's specific share.

If your real goal is "any chase card from Sandstorm" rather than "Raichu ex specifically", the math gets dramatically friendlier — the wait drops to ~5 packs on average for the tier as a whole. Most binder collectors approach it this way: chase the tier broadly across multiple sets, accept whatever pulls, and snipe the specific holes via TCGplayer later. Targeting one card from a thick tier is the most expensive way to play the chase, and Raichu ex is no exception.
