Underground ExpeditionCelestial Storm · #168/168 · Rare Ultra · 2018
The Hoshino Verdict
What this card’s market is actually doing — scored, stated and kept current.
Hoshino recorded 38 confirmed sales of this card in the last 12 months across 2 venues. The market price is up 3% over the year, up 4% over 90 days and flat over 30 days. PSA has graded 436 copies of it, 265 of them Gem Mint 10 — a 60.8% gem rate (CGC 67, BGS 13 further). The most recent sale we hold is 15 days old.
Why is it expensive? It prices in the top 8% of the catalogue because only 265 copies have ever reached PSA 10 of the 436 PSA has graded and it is a rare ultra from Celestial Storm (2018).

Descriptive market data, not investment advice. The Hoshino Score measures how deep, liquid, widely-traded, dear and scarce this card’s market is from sales and population records we hold. It is not a forecast, not a recommendation, and not a rating of this card as an investment.
Price by grade
What each grade’s real sales say — median of what actually sold.
Each grade is priced on the median of its own real sales — never averaged across grades, and never across printings. A 1st Edition, Shadowless or No Rarity copy is a different market from the ordinary print, so it gets its own row; where a grade holds sales of more than one printing and we cannot tell which copy sold, it is shown without a price — we abstain rather than publish the blend.

How confident are we in each of these prices?
There is no weighting and no hidden formula here. We ask five plain questions about the sales behind a price, and the rating is simply how many of them we can answer yes to. Every threshold is the one our pricing engine already uses to decide whether it trusts its own answer — none was invented for this rating. A grade we publish no price for gets no rating either: there would be nothing to rate.
- ✓Enough sales to have a middle — 30 confirmed sales at this exact grade (the observation count beside this rung also includes 2 rows reconstructed from a listing’s own lifecycle rather than a confirmed sale — those never count toward this check)
- ✓Those sales agree with each other — The middle half of them spread 48% around the median
- ✓The market traded it recently — Most recent sale 23 days ago
- ✓More than one marketplace — Sales came from 4 different marketplaces
- ✗Dated by the venue, not by us — 30 of 30 came from venues that publish no sale date, so those dates are the day we recorded the sale — an upper bound on when it actually traded
- ✗Enough sales to have a middle — 2 confirmed sales at this exact grade — under the 5 our pricing engine treats as a settled sample
- ✓Those sales agree with each other — The middle half of them spread 11% around the median
- ✓The market traded it recently — Most recent sale 23 days ago
- ✗More than one marketplace — Every sale came from the same marketplace, so this is one venue’s price rather than the market’s
- ✗Dated by the venue, not by us — 2 of 2 came from venues that publish no sale date, so those dates are the day we recorded the sale — an upper bound on when it actually traded
- ✗Enough sales to have a middle — 3 confirmed sales at this exact grade — under the 5 our pricing engine treats as a settled sample
- ✓Those sales agree with each other — The middle half of them spread 2% around the median
- ✓The market traded it recently — Most recent sale 23 days ago
- ✓More than one marketplace — Sales came from 2 different marketplaces
- ✗Dated by the venue, not by us — 1 of 3 came from venues that publish no sale date, so those dates are the day we recorded the sale — an upper bound on when it actually traded
Where a rung reads last recorded, its most recent sale came from a venue that publishes no sale date — Mercari Japan publishes none — so that date is the day we recorded the sale, an upper bound on when it sold. The price is real; the date is an observation and we will not dress it up as a timestamp.
Cross-market comparisons and arbitrage routes are computed within one grade — PSA 10 against PSA 10, raw against raw. A route is never built from two different grades.
The same card in a different holder
What the market pays for this card at the same grade in each grader’s slab — and, if you hold one, what cracking it would have to return to be worth the fee.
Each grader’s price below is the median of that grader’s own recorded sales of this card at this exact grade. Nothing is averaged across graders and nothing is interpolated from a neighbouring grade. Every price here is the same figure the price-by-grade table above publishes — a rung that table abstains on is abstained on here too, and every fee, freight and tax figure is a real published rate from our cost model.
TAG 10 vs PSA 10
We can price a TAG slab because TAG slabs sell in public and we record those sales. We cannot tell you your chance of getting a 10 from TAG: that needs population data — how many of each grade TAG has issued for this card — and we hold none. TAG publishes no population report of the kind PSA, CGC and BGS do. So there is no “submit to TAG” route on this page, and we will not model one.
Price trend
Median market price over time, plus the sale-by-sale receipts.
Each point is a real recorded sale at that grade, over the full time we hold. Grades trade at very different prices, so the trend is per grade — pick a grade above.

The 4 most recent — confirmed sales first, then estimates; distinct price points, identical re-ingested rows count once, never stacked. The full 42-point sale-by-sale history unlocks with Pro. Venue is the marketplace the sale actually cleared on — eBay, Goldin, ALT, Fanatics, SNKRDUNK and the rest — established from the sale’s own listing URL, its auction house, or the feed’s own declaration of the venue. A via tag names the data feed that delivered the record; the feed is never the venue. Where none of those establish a marketplace the row says venue not disclosed rather than naming one we cannot prove. Rows tagged guide are marketplace price-guide points (TCGplayer market / Cardmarket trend), not confirmed sales; rows tagged est. are inferred from a listing that left the market, not directly-recorded sales. Rows tagged recorded come from a venue that publishes no sale date — Mercari Japan publishes none — so the date shown is the day we recorded the sale, an upper bound on when it sold. The price is real either way; we do not invent a date.

Daily market prices across 3 platforms in North America, Europe — counts are distinct sales, never duplicated listings. Guide rows (TCGplayer market / Cardmarket trend) are labelled as estimates, not sales. A recorded tag means that venue publishes no sale date, so its date is the day we saw the listing sold.

Every point is a real population reading taken on the date shown — first reading 2026-08-27, latest 2026-09-20 (24 days). That is the whole window we hold for this card; it is not a one-year trend and we will not present it as one. A population can only grow — a card cannot be un-graded — so where a reading came back lower than the one before it, that is a partial crawl and the series carries the higher figure forward rather than drawing a fall that never happened.
Why this matters: scarcity is a flow, not a constant. A tier whose count is climbing is getting less scarce while its price chart says nothing at all — and a tier that has not moved in weeks is holding its scarcity. Nobody else publishes this per grade.
What grading this card would actually cost you
Every term in the sum, sourced — the slab’s real sale price, the marketplace’s published fee, the grader’s published rate.
Every graded row is that same sale, minus the same marketplace fee, minus the grader’s published fee, minus $12 of shipping both ways. The “vs raw” column is the only number that matters: what that outcome would leave you with over selling the card as it is now.

“Of existing slabs” is how PSA’s 436 graded copies of this card actually landed. It is the base rate for the population, not the odds for your copy — the copies people submit are not a random sample, and we have never seen the card in your hand.
What this cannot tell you. Which grade your copy would get. That depends on centring, edges, surface and corners on the card in your hand, and we have never seen it — so there is no single headline number here and no “worth it / not worth it” verdict. Each row is one outcome, priced from that tier’s own real sales; a tier we publish no price for stays blank rather than borrowing a figure from the grade next to it. Turnaround is the grader’s published business-day estimate, and the market can move inside it. Descriptive market arithmetic, not investment advice.

Who is looking at this card
Demand and supply signals that move before price does.
This is where the attention layer goes: how much YouTube activity this card is getting (demand) against how many copies are listed for sale right now (supply). Rising demand into falling supply is the setup that moves before the price does — the leading indicator this category does not have.
We hold no readings for this card, so there is no number here. The model is built (src/attention); the collector has not run against this database yet, and until it has, an attention score would be something we made up. A blank panel that says so is the honest version of this section.

What Underground Expedition actually does
The printed card — its attacks, what they cost, what it is weak to, and whether it is still tournament legal.
Card text, attacks and format legality come from the open card catalogue TCGdex. They describe the card as printed; nothing here is a price, an estimate or anything Hoshino computed. A field we hold no record for is left out rather than filled in.
