BREAKthrough EV methodology
| Formula | Sum every slot contribution: rare-tier probability × average priced card value, plus fixed common/uncommon/energy slot count × average priced card value. |
|---|---|
| Assumptions | Uniform card selection within each rarity tier; raw ungraded USD market values; no grading premium, condition spread, sealed appreciation, or first-edition split. |
| Data source | Card pools from the bundled Pokemon TCG API catalog; prices from the bundled TCGplayer market snapshot; slot probabilities from the simulator pull-rate model. |
| Update cadence | Regenerated by prerender; price values update when npm run build:prices or the full data pipeline refreshes the snapshot. |
| Limitations | EV is a long-run mean, not the median pack result; one pack can land far below or above this number. |

Expected value (EV) is the average payout you'd get per booster pack if you opened thousands of BREAKthrough packs and summed the resulting card values at current market prices. It's the single most useful number for deciding whether a sealed product is worth opening vs holding.
Per-pack EV: $19.65
This is high-EV territory. The number is calculated from the live TCGPlayer market price snapshot in PackRip's catalog (refreshed every build via build-prices.mjs) multiplied by the authentic per-card pull rate baked into the simulator. EV does not account for grading premiums, sealed product appreciation, or first-edition variants — it's the raw "rip and sell" expectation for unlimited / non-graded copies.
EV breakdown by rarity slot
A BREAKthrough pack contains 10 cards: 1 rare slot, 3 uncommons, 4 commons, and 1 energy. Each slot contributes to total EV:
| Slot | Per-pack rate | Pool | Avg price | EV contribution |
|---|---|---|---|---|
| Full Art | 5.56% | 10 cards | $59.74 | $3.321 |
| Mega EX | 5.56% | 4 cards | $24.28 | $1.350 |
| BREAK | 11.10% | 6 cards | $5.57 | $0.618 |
| Pokémon-ex | 16.70% | 4 cards | $6.98 | $1.165 |
| Secret Rare | 5.00% | 2 cards | $162.39 | $8.120 |
| Rare Holo | 28.00% | 16 cards | $3.83 | $1.071 |
| Rare | 28.08% | 21 cards | $0.39 | $0.111 |
| Uncommon | 3 per pack | 47 cards | $0.65 | $1.955 |
| Common | 4 per pack | 53 cards | $0.30 | $1.195 |
| Energy | 1 per pack | 2 cards | $0.74 | $0.740 |
Top 8 cards driving the EV
These are the cards contributing the most expected value to a single BREAKthrough pack — the chase pulls that, weighted by how often they actually appear, do the most work in keeping the EV up:
- #1. Mewtwo-EX (Secret Rare, $165.81) — adds $4.145 to per-pack EV
- #2. Mewtwo-EX (Secret Rare, $158.97) — adds $3.974 to per-pack EV
- #3. M Mewtwo-EX (Full Art, $149.63) — adds $0.832 to per-pack EV
- #4. M Mewtwo-EX (Full Art, $125.31) — adds $0.697 to per-pack EV
- #5. Gengar (Rare Holo, $35.13) — adds $0.615 to per-pack EV
- #6. Burning Energy (Energy, $1.13) — adds $0.565 to per-pack EV
- #7. M Mewtwo-EX (Mega EX, $34.43) — adds $0.479 to per-pack EV
- #8. M Mewtwo-EX (Mega EX, $33.57) — adds $0.467 to per-pack EV
Variance is everything
EV is the long-run average. A single BREAKthrough pack will almost always be below EV — the median pack pulls one rare and four bulk commons. The high-end pulls (Crystal, Shining, Holo Rare) drag the average up because they're rare and valuable. If you open a single sealed booster expecting the EV, you'll be disappointed; if you open a sealed box (36 packs), the law of large numbers makes the actual return cluster much closer to the EV.

EV math walkthrough — in plain English
The arithmetic on this page is simpler than it looks. A BREAKthrough pack has 10 cards in fixed slots: 1 rare-slot card (which itself rolls across 7 sub-tiers — Holo Rare, Mega EX, Full Art, etc.), 3 uncommons, 4 commons, 1 energy. For each slot, you take the probability of pulling each card in the pool, multiply by that card's TCGPlayer market price, and sum. The rare-slot contribution dominates because the chase cards are 10-100× the price of a bulk common — even at 1-in-30 odds, a $166 chase card contributes more per pack than 6 bulk commons combined. BREAKthrough's total EV of $19.65 is the sum of those slot contributions. If you opened 1,000 packs and sold every card at TCGPlayer market, you would expect to receive approximately $19647 — give or take the standard-deviation noise of the chase pulls.
EV is theoretical — single packs almost always disappoint
The single most important caveat about EV: it is the long-run mean, not the median single-pack result. The median BREAKthrough pack pulls one rare and four bulk commons and is worth $1-3 (well below the $19.65 headline number). The upside lives in the chase pulls, which are rare by definition. The distribution of pack values is heavily right-skewed: most packs are below EV, a small fraction of packs are massively above EV, and the average across thousands of packs eventually converges to the headline number. This is the same statistical structure as lottery tickets, slot machines, and any other pull-based randomization — the math is honest, but human intuition is calibrated to medians, not means, so the "expected value" rarely matches the felt experience of opening one pack at a time. If you open a sealed booster box (36 packs), the law of large numbers kicks in and your actual return clusters much closer to 36 × $19.65 = $707.
EV vs sealed pack market price — is BREAKthrough worth ripping?
The standard sealed retail price for a Pokémon booster pack at original release was $4 USD. Sealed BREAKthrough (2015) packs on the secondary market today routinely trade for $4-10 depending on box-fresh vs loose-pack condition. The buy-vs-rip decision math is simple: if EV ($19.65) is meaningfully above the sealed-pack secondary-market price, ripping is the higher-EV financial play (with all the variance caveats). If EV is below or equal to the sealed price, the sealed pack itself is the better asset — the sealed-pack market also enjoys appreciation independent of the underlying card values because sealed product is non-replenishable inventory. For BREAKthrough at $19.65 EV: this sits in the gray zone — sealed pack pricing determines the verdict.
Why pulling beats buying when EV is way above pack price
The case for ripping BREAKthrough packs hinges on a wider EV-to-sealed-price spread. When EV is 2× or more above the sealed pack price, you can rationalize ripping for three reasons: (1) the chase upside is asymmetric — most packs are below EV but the right-tail chases (Mewtwo-EX at $165.81, contributing $4.145 per pack to EV all by itself) can return many times the pack cost in a single pull; (2) the cards themselves are usable in the simulator collection and PSA-gradable for further upside; (3) the experience itself has value (the pack-rip dopamine is what built the entire collecting hobby). The case against ripping when EV is below pack price is purely financial — you're paying $X for a $X EV outcome but eating all the variance, which is a strictly dominated trade vs buying the chases directly on TCGplayer. PackRip lets you simulate the rip for free either way, so the decision is risk-free at the consumer level — only your real-world wallet is on the line.
