A single-digit median decline is easy to over-read until you remember what the first week of a set actually is. Listings are thin, sellers price on hope, and a handful of optimistic asks set the record for everybody. By week two the box-opening wave has passed, cards are in binders, and the prices are being set by people who own the cards rather than people guessing about them. A median of −6.4% across 38 measured cards is the normal shape of that landing.
What matters is the distribution underneath it. Ten cards went the other way, several by double digits, and the chase tiers behaved nothing like the commons. So rather than one number, here is the whole set, sorted by what actually happened.
Winners: the five biggest risersInkSight · One Piece Card Game · as of August 14, 2026
Every card below cleared the same bar: at least three snapshot days in both windows, verified or moderate confidence, and at least $2.00 on both ends so bulk noise cannot manufacture a headline percentage.
| Card | Rarity | Jul 31–Aug 6 | Aug 8–Aug 14 | Change |
|---|---|---|---|---|
| Edward.Newgate (Alternate Art) | SR | $23.01 | $37.50 | +63.0% |
| Portgas.D.Ace (118) | SEC | $10.91 | $14.48 | +32.7% |
| Portgas.D.Ace (001) (Alternate Art) | L | $43.25 | $55.56 | +28.5% |
| Marco (Alternate Art) | R | $7.88 | $10.06 | +27.7% |
| Portgas.D.Ace (118) (Alternate Art) | SEC | $28.77 | $34.85 | +21.1% |
Edward.Newgate (Alternate Art) is the story of the set: $23.01 in release week against $37.50 now, +63.0%, and it did it on 7 snapshot days in the current window rather than one spike. Below it the gains get modest fast — the 5th-best riser in the entire set is only +21.1%. A set with one strong riser and a thin tail behind it is a set where demand is concentrated, not broad.
Losers: the five biggest declinesInkSight · One Piece Card Game · as of August 14, 2026
The same bar, the same windows, the other end of the table. Note how many of these are mid-price cards rather than chase cards: the steepest declines in a young set are usually the $4–$8 rares that release-week speculation over-bid.
| Card | Rarity | Jul 31–Aug 6 | Aug 8–Aug 14 | Change |
|---|---|---|---|---|
| Emporio.Ivankov (026) (Alternate Art) | SR | $7.12 | $5.22 | −26.7% |
| Zehahahahaha! (Alternate Art) | R | $116.02 | $89.75 | −22.6% |
| Monkey.D.Luffy (034) (Alternate Art) | R | $10.85 | $8.59 | −20.8% |
| Monkey.D.Luffy (022) (Alternate Art) | L | $78.25 | $62.35 | −20.3% |
| Kin'emon (Alternate Art) | SR | $13.91 | $11.17 | −19.7% |
The steepest faller, Emporio.Ivankov (026) (Alternate Art), is −26.7% — from $7.12 to $5.22. At that price level a decline like this rarely means the card is bad; it means release-week asks were being set against almost no supply, and supply arrived. The one genuinely expensive card in this list, Zehahahahaha! (Alternate Art), is the exception worth watching, because thin high-value markets move on very few sales in either direction.
Chase check: where the top of the set landedInkSight · One Piece Card Game · as of August 14, 2026
Chase rarities are the cards people buy the set for, and they are also the thinnest markets in it. Here is the median of each chase tier in release week against the median now — measured across every printing in the tier, so one outlier cannot carry the number.
- Manga Rare — median $1,166.00 → $1,161.82 −0.4%, 1 of 3 printings higher than release week.
- Secret Rare — median $14.96 → $16.94 +13.3%, 2 of 2 printings higher than release week.
- Alternate Art — median $23.01 → $23.07 +0.3%, 6 of 25 printings higher than release week.
- Treasure Rare — median $21.99 → $25.59 +16.4%, 1 of 1 printings higher than release week.
The chase tiers split, which is the more common outcome and the more useful one: some of the top of The Time of Battle is holding while the rest has given ground. The Manga Rare tier gave back −0.4% against its opening median, and the Secret Rare tier +13.3% — with 2 of its 2 printings bucking that. These are also the cards where a single sale moves the print, so treat every figure in this section as the centre of a range rather than a quote.
Sealed math: what a box is actually worthInkSight · One Piece Card Game · as of August 14, 2026
The cheapest The Time of Battle booster box listed on TCGplayer as of August 14, 2026 asks $200.00, against a Market price of $209.37. Our own snapshots put the box at $206.86 in release week against $209.83 now, +1.4%.
Why there is no EV verdict hereThe only slot odds anyone has for this game describe the base rarities. The cards that actually carry a One Piece Card Game box — manga rares, alternate arts, parallels — have no published slot rate, so we cannot price the hits that matter most. $81.00 is what the base printings in 24 packs are worth at today's medians: a floor, not an expected value, and not a verdict on whether $200.00 is a good price. We would rather leave that judgement to you than invent the missing half of it.

Floor basis: Bandai does not publish official One Piece pull rates. Weights below are modeled from community-aggregated box breaks (r/OnePieceTCG megathreads + TCGPlayer sealed-break streams, 2024-2026). Simulated for entertainment. Base-printing slot values: 8 x Common $0.74 · 2 x Uncommon $0.30 · 1 x Rare-or-better #1 $1.49 · 1 x Rare-or-better #2 $0.85. It counts singles value only — no shipping, no fees, no time cost of selling, and no value for opening the packs yourself.
MethodInkSight · One Piece Card Game · as of August 14, 2026
What these numbers are. Every figure on this page is a trailing seven-day median of InkSight’s own stored daily TCGplayer snapshots — the price a copy was listed or marked at on the day we recorded it. These are asks and Market prices, not confirmed sales data, and no third party’s sold-listing feed is used anywhere in this article.
Windows. Release week is Jul 31–Aug 6, 2026. The current window is Aug 8–Aug 14, 2026. A card needs at least three snapshot days inside both windows to appear; cards we did not begin tracking until after release are omitted rather than back-filled. We also hold 43 snapshot days for this set from before release (first recorded Jun 18), and every one of them is excluded: pre-release rows are presale and preorder asks with no market behind them, so the baseline here starts on release day itself, Jul 31, and never earlier.
Filtering. Only cards flagged verified or moderate confidence by our snapshot classifier are eligible, and both ends must be at or above $2.00. That leaves 38 eligible cards out of 155 printings we track for the set. Medians in the chase section are computed over every paired printing in the tier, including ones below the $2.00 floor.
Sealed EV. Modelled from the same slot plan and rarity weights as the InkSight Pack Lab simulator, priced against current medians. Publishers do not publish per-slot pull rates; the weights are estimates and are labelled as such wherever they appear.
What we do not do. No forecasts, no target prices, no buy or sell advice. Where a market is too thin for a number to mean much, we say so instead of quoting it with false precision.
