Delta Reign After Release: What Changed in Its First Week?

Most of the Delta Reign cards we could compare became cheaper during release week. Across 11 English chase-card printings with observations on different dates, 10 recorded a lower asking price. The median change was −34.9%. One went the other way: Mega Rayquaza ex #141 rose 23.2%.

That is a useful snapshot of early price discovery, with an important boundary: these are the lowest ungraded Near Mint asking prices recorded on Cardmarket, in euros. They are not completed sales, and the sample does not represent the entire expansion.

Mega Evolution—Delta Reign launched on 6 November 2026. We studied its first seven calendar days, 6–12 November, using UTC dates and excluding presale quotations. The results help explain why a new Pokémon set can feel expensive at launch, then become more affordable surprisingly quickly—and why the biggest chase card may behave differently.

What happened to Delta Reign prices in week one?

We checked the 38 numbered Illustration Rare, Ultra Rare, Special Illustration Rare and Mega Hyper Rare cards, #104–141, using each card’s default holofoil printing. Of those, 29 had at least one eligible English observation during the week. Only 11 had observations on two or more different dates, so those 11 form the English comparison.

The median is calculated from each card’s percentage change. It describes the middle result in this small sample; it does not mean that every Delta Reign card fell by roughly a third.

The dates matter, too. We compared each card’s first and last observed quote inside the week. Some comparisons begin on 6 November, others later; several end before 12 November. This is a study of changes observed within release week, rather than a uniform launch-day-to-day-seven return.

Here is the complete English sample. Each line shows the observed dates, lowest eligible asks and percentage change:

• Electivire #108, Illustration Rare: 6–9 November, €4.95 → €2.50 (−49.5%).

• Groudon #111, Illustration Rare: 9–12 November, €14.82 → €14.80 (−0.1%).

• Inkay #113, Illustration Rare: 6–9 November, €5.50 → €3.26 (−40.7%).

• Altaria #116, Illustration Rare: 6–11 November, €8.50 → €5.53 (−34.9%).

• Talonflame ex #124, Ultra Rare: 6–9 November, €12.35 → €7.99 (−35.3%).

• Zinnia’s Trust #131, Ultra Rare: 6–9 November, €4.99 → €3.00 (−39.9%).

• Bubbly Water Energy #132, Ultra Rare: 6–9 November, €5.00 → €2.00 (−60.0%).

• Mega Golisopod ex #135, Special Illustration Rare: 6–9 November, €24.95 → €18.18 (−27.1%).

• Mega Golurk ex #137, Special Illustration Rare: 7–9 November, €23.99 → €23.40 (−2.5%).

• Zinnia’s Trust #140, Special Illustration Rare: 6–11 November, €29.90 → €22.17 (−25.9%).

• Mega Rayquaza ex #141, Mega Hyper Rare: 7–11 November, €200.00 → €246.30 (+23.2%).

The difference between percentage and cash savings is worth keeping in view. Bubbly Water Energy’s 60% decline represents €3.00. Mega Golisopod ex fell by a smaller percentage but €6.77 in cash. Shipping can easily change the economics of buying a single inexpensive card.

The German sample also moved lower overall: 13 of 16 repeat-observed printings fell, three rose, and the median change was −22.6%. Those are different card groups with different observation dates, so the English and German results do not establish a language premium or which language “held its value better”.

Why can new Pokémon card prices fall so quickly?

A release opens with uncertainty. Buyers and sellers are still discovering how many copies will be offered, which artworks collectors want most and which cards players need.

One plausible mechanism is an early-access premium. A collector who wants a particular card immediately may accept a price that a more patient buyer would reject. As more packs are opened and more copies are listed, sellers can face greater competition. A lower asking price may then be enough to attract the next buyer.

That is an explanation for how a launch premium can unwind, not a measured cause of each Delta Reign decline. Our observations track prices; they do not tell us how many packs were opened, how quickly cards sold or why an individual seller changed an offer.

Lowest asks are especially sensitive to individual listings. A new inexpensive copy can pull the recorded minimum down. If that copy sells or is withdrawn, the next observation can rise even without a broad increase in demand. A visible drop is useful information, but it deserves more context than a single percentage.

Did earlier 2026 releases show the same pattern?

To put Delta Reign in context, we checked three earlier releases against the publisher’s release calendar: Chaos Rising, Pitch Black and 30th Celebration.

For these older English-language cohorts, we compared the median of each card’s observed daily lowest asks during release days 1–3 with its equivalent during days 5–7. Each comparison keeps the same card, default printing and Near Mint condition. A card needs data in both windows to qualify.

• Chaos Rising, released 22 May: 29 qualifying cards; 18 fell, nine rose and two were unchanged. The median card-level change was −5.9%.

• Pitch Black, released 17 July: 22 qualifying cards; 18 fell, three rose and one was unchanged. The median change was −11.2%.

• 30th Celebration, released 16 September: 20 qualifying cards; all 20 fell. The median change was −28.5%.

Together, 56 of 71 qualifying cards recorded lower asking prices in the later window. All three set samples had a negative median. Requiring observations on at least two dates in each window leaves 54 cards, of which 45 fell, so the direction also survives that stricter coverage check.

These results support early price cooling as a recurring pattern in this bounded sample. They do not provide a universal Pokémon release rule. The earlier cohorts use multi-day medians, while Delta Reign uses first and last observed quotes, so their percentages should not be treated as a league table of which release fell fastest.

There is also no “cheapest after seven days” conclusion here. Establishing when prices fall fastest—or reach a low—would require denser observations across the following weeks and months.

Why the headline chase card can behave differently

Mega Rayquaza ex #141 is the clearest exception in our Delta Reign sample. Its lowest recorded eligible ask rose from €200.00 on 7 November to €246.30 on 11 November, even as most other sampled cards became cheaper.

This is the Mega Hyper Rare #141, not the Special Illustration Rare #138. The Pokémon name alone is not enough to identify the product being priced.

A particularly desirable printing can face a different balance of buyers and available copies from the rest of a set. Our data do not establish whether that explains Rayquaza’s rise. They do show why an expensive headline card should not stand in for every other card in the expansion.

The reverse also matters: falling prices on several Illustration Rares do not guarantee that a scarce chase artwork will follow them down.

What collectors can take from the first week

For a collector building a binder without a deadline, the evidence gives patience a practical rationale. Several cards in this sample became meaningfully cheaper within days. Buying everything at the first available quote can mean paying for immediacy.

Before deciding whether to wait, compare the exact card number, printing, language and condition. Check when the quote was recorded, look beyond a single low offer and include shipping in the price you would actually pay. A €2 card from another seller may cost more delivered than a €3 card added to an existing order.

If you need a card for an event or simply want it now, that immediacy has value to you. A spending limit is more useful than assuming that every new card will decline on the same schedule.

Use the Delta Reign set page to find the exact printing, then inspect its price history in the language you collect. For a longer view of how individual cards can diverge from broad market figures, see our 90-day Cardmarket study.

Method and limits

Source and window: CollectHolo’s stored Cardmarket observations, analysed on 13 November 2026. The Delta Reign window runs from 00:00 UTC on 6 November to immediately before 00:00 UTC on 13 November. No presale quote or later observation enters the comparison.

Comparable products: ungraded Near Mint cards, priced in EUR, with language and default holofoil printing held fixed. The candidate group contains 38 numbered chase-card printings per language, #104–141. Stamped variants, other finishes, graded copies and cards outside that group are excluded.

Coverage: 88 eligible observations across both languages, yielding 88 daily snapshots after selecting the latest quote for each card, language, printing and UTC date. English coverage is 29 cards with any observation and 11 with repeat dates; German coverage is 28 and 16 respectively. Missing days are not filled, and single-observation cards are excluded from change calculations.

Calculation: percentage change = (last observed ask ÷ first observed ask − 1) × 100. We report the median of those card-level percentage changes, giving each sampled card equal weight. Prices exclude shipping and fees. Lowest asks can be volatile and do not prove that a transaction occurred at that price.

Historical context: the same ungraded, Near Mint, English and default-printing filters apply to Illustration Rare, Ultra Rare, Special Illustration Rare and Mega Hyper Rare cards in the three earlier sets. Their baseline and end windows use medians of observed daily lowest asks, without carrying prices forward. Perfect Order was also checked but had no qualifying comparison and was excluded. The cohorts are coverage-selected, not random samples of all releases or all cards.

Interpretation: these are historical asking-price observations, not an index of the whole set, realised resale proceeds or a forecast. Price changes alone cannot establish supply growth, buyer demand or a future bottom.
