30th Celebration: ETB −11.9%, Booster Box CN −41%

The cheapest 30th Celebration Elite Trainer Box in Poland costs 545.99 zł on 17 October, 11.9% less than on 15 September, and there are now 22 offers instead of 2. The cheapest booster box, in practice the Chinese edition, dropped 41% in one day and costs 540 zł. For the ETB, 11 of the 12 cheaper listings are also sold out.

This report puts our own CardPulse data from three markets side by side: Poland, Germany and the US. We separate what is documented from what is only a hypothesis, and we look ahead to the Delta Reign release on 6 November.

Polish ETB prices are down 11.9% since release, with eleven times as many offers

The lowest price of the 30th Celebration Elite Trainer Box in Polish shops fell from 620 zł on release day to 545.99 zł on 17 October. The low of the period was 534.90 zł on 15 October.

Data: lowest available price in Polish shops according to CardPulse, 15 September to 17 October 2026; "offers" are shops with the product on sale that day.

• 15 September (release). 620 zł, 2 offers. That is effectively one or two shops, so it says little about the market.
• 18–19 September. 680 zł, 2 offers. This is the peak of the period; from there the price fell 19.7% by 17 October.
• 21 September. 590 zł, 8 offers. The number of shops rose from 2 to 8 within three days.
• 23 September to 11 October. 599 zł for 19 days, 9 to 13 offers. The price held even as more shops joined.
• 12 October. 545.99 zł, 14 offers. A 53 zł drop in one day, or −8.8% from 599 zł.
• 14–17 October. 545.99 zł with 18 to 24 offers; briefly 534.90 zł on 15 October.

The pattern is simple: the price did not slide smoothly, it dropped in steps. For almost three weeks it stayed at 599 zł, then one shop cut its offer and the rest of the market followed.

That is exactly what the ETB price page shows: flat stretches and vertical drops instead of a gentle curve.

11 of the 12 cheapest ETB listings in Poland are sold out

The lowest ETB price of 545.99 zł is the only in-stock offer among the 12 cheapest shop listings in our database. The other 11 range from 349 to 549 zł but are unavailable according to the shop's last check.

Data: 30th Celebration ETB listings in Polish shops in the CardPulse database, as of 18 October 2026; availability as of the shop's last check; Cardmarket listings excluded.

That explains the stepped shape of the chart: the lowest price describes the cheapest goods you can actually buy, not the cheapest listing in the shops. When a cheap shop sells out the price jumps up, and when a new delivery arrives it falls. This fits the data, but we have not checked it for every day.

There are 64 ETB listings in Poland in total, 24 of them in stock. The 22 offers in the chart therefore describe shops with goods on sale, not every product page.

The practical takeaway: a price of 430 zł from the list is not a price you can enter at today. Check availability before you treat it as a benchmark.

The "booster box" curve mostly measures the Chinese edition, not the English one

The lowest price in the 30th Celebration Booster Box category fell from 900 zł to 529.99 zł on 7 October, a 41.1% drop in one day. On 17 October it stood at 540 zł, but the cheapest in-stock "booster box" is the Chinese edition, and the only English offer costs 948.90 zł.

Data: lowest available price in Polish shops according to CardPulse, Booster Box category (all language versions), 18 September to 17 October 2026; category composition as of 18 October.

The Polish category holds 38 listings: 27 in English (mostly Mini Tin Displays), 8 Chinese, 2 Japanese and 1 Korean. Of the 7 listings with "Booster Box" in the name, 3 are Chinese, 2 Japanese, 1 Korean and 1 English.

• 540 zł, Chinese edition (panmysza). In stock. This is the chart price of 17 October.
• 529.99 zł, Chinese edition (swiatkart). Sold out. Exactly the same amount as the 7–16 October level.
• 499.99 zł, Chinese edition, preorder (razorcards). Sold out.
• 599.99 zł, Korean edition (lootquest). In stock.
• 948.90 zł, English edition (gnom). In stock, the only English offer with "Booster Box" in the name.

The fact that 529.99 zł matches the level from 7 October suggests the drop was not a price cut on the English product but the appearance of the cheaper Chinese edition. We cannot see when the listing appeared, so this is a hypothesis, not a finding.

Tip: for booster boxes always check the language version in the listing title (EN, JP, CN, KR). The Chinese and English editions are different products with different prices and different demand.

Germany and the US: same direction, different size of decline

The ETB got cheaper in all three countries, most in the US (−30.5%), less in Germany (−18.8%) and in Poland (−11.9%). Part of this is because the data series in the US and Germany start on a day with only one or two offers.

Data: lowest available price of the 30th Celebration ETB according to CardPulse in each country, from the first day with data to 17 October 2026; prices in local currency, not converted and without shipping.

In Germany the price was jumpy: €174.99 on 28 September, €139.95 from 3 to 11 October, a jump to €159.95 on 12 October and €129.99 from 15 October. Measured from the 28 September peak, that is −25.7%.

In the US the price reached $134.99 on 5 October with 12 offers and $124.99 on 11 October. Since then it has sat at around $125.

Among the changes of the last three days, single cuts stand out: rlsportscards from $165 to $125 (−24.2%) and breakthecase in Germany from €180 to €170 (−5.6%). The second offer is not the cheapest in the country, though, since the lowest price in Germany is €129.99.

In the US the four cheapest in-stock offers (excluding Cardmarket) range from $125 (rlsportscards) to $139.99 (cashcardsunlimited); the other two are $129 (stompinggrounds) and $135 (skyboxct). The spread between the cheapest and the fourth is 12%, and 14 of 39 listings are in stock.

In Germany we see a discrepancy we cannot explain. The series low of 17 October (€129.99) does not appear in the offer list of 18 October. The cheapest in-stock shop offers (excluding Cardmarket) are €164.99 (B-grade, cardsrfun) and €170 (new, breakthecase). Treat the €129.99 price with caution.

A word on suggested retail prices: for Poland we have no documented manufacturer price, so we do not state a percentage markup. One foreign guide site lists $49.99 for the US ETB (unofficial source, not confirmed by the publisher). If that is right, the cheapest US ETB costs 2.5 times that price.

We do not compare the "box" category in Germany (€29.95) and the US ($65) with Poland. The cheapest entries are Chinese Card Display Sets (yonkotcg in Germany, nxtlegaci in the US), and in Germany 24 of the 38 listings in the category are the Chinese edition.

Why are prices falling? Four hypotheses

The causes cannot be read from prices alone, so these are hypotheses, not findings. Each one can be tested against upcoming data. Three concern the ETB, the fourth the Booster Box category.

1. Growing supply. In Poland the number of shops with the ETB rose from 2 to 22, in Germany from 1 to 9. More sellers usually mean more price competition. Further falling prices with a rising number of offers would support this.
2. Cooling initial demand. The release was on 16 September and scarcity drove the price before that. Falling prices even after the number of offers stops growing would support this.
3. Changing mix of offers. In the Booster Box category the 41% jump may come from the cheaper Chinese edition appearing rather than from a cut on one product. A price comparison of English offers only would support this.
4. Single-seller effect. The stepped shape of the charts suggests one shop cuts and others react with a delay. One-day jumps like 7 and 12 October would support this.

We described the same phenomenon from the cards' point of view in the article on falling card prices. There the starting point was media reports; here it is our own data on sealed products.

Data: on 17 October CardPulse checked 175 shops and recorded 766 price or stock changes and 39 new products. That is the backdrop for every number in this report.

Delta Reign on 6 November: what can and cannot be concluded

According to our release calendar Delta Reign releases on 6 November 2026, but price data for this set is still too thin to conclude anything.

Data: lowest available price in Polish shops according to CardPulse, 8 to 17 October 2026.

• Delta Reign booster box. 849 zł on 8 October, 799 zł on 17 October (−5.9%). There are only 2 offers.
• Delta Reign ETB. 369.99 zł with one offer, unchanged over three days.

Two offers are not enough for a trend. We treat these numbers as a reference point to return to after release, once the number of shops has grown.

What can already be said: with 30th Celebration the ETB price did not fall smoothly in the first two weeks and then dropped 53 zł in one day. If a similar pattern appears with Delta Reign, the first days after release will carry little information. That is a hypothesis, not a forecast.

What this means for players, collectors and sealed buyers

The same numbers read differently depending on why you buy. Here are three perspectives, with no recommendation and no price forecast.

Players who want to play

If you need cards for a deck, ETBs and displays are only one of several ways to get them. An 8–12% fall in sealed prices in Poland does not change the fact that single cards can be bought separately. If you want specific cards, compare the cost of the set with the price of the singles you need.

Collectors

Sealed collectors care about availability and the condition of the packaging, not only price. With more offers it is easier to find a copy in good condition, but the data says nothing about whether the price will be higher or lower in a year. Prices from the first weeks after release are usually the least stable because they rest on few shops.

Long-term sealed buyers

Anyone buying sealed to store it risks two scenarios: the price may keep falling if supply grows, or recover if stock runs out. Our data shows only the first over the last four weeks. We do not know how the next quarter will go, and weighing that risk is up to you.

• Pointing to falling prices: 22 ETB offers in Poland instead of 2, stepwise cuts by several shops and three countries moving the same way.
• Against a simple conclusion: few offers at the start, a jumpy price in Germany (from €139.95 to €159.95 and back within days) and a Booster Box category that mixes language versions.

The 30th Celebration sealed market is still looking for its price level. After four weeks there is no stable floor yet.

How to use this: five steps

We do not give a purchase recommendation. The data shows how prices behaved, not how they will behave. Here is one way to check the situation yourself.

1. Open the price history. On the product page look at the lowest-price chart and switch to the median to see whether the drop affects one shop or the whole market.
2. Compare the number of offers. A price from one shop is an anecdote, a price from 20 shops is a market.
3. Check the language version. English, Japanese and Chinese editions have different prices, so compare like with like.
4. Add shipping. A 5–10 zł difference between shops can wipe out the saving from a promotion.
5. Set a price alert. With a free account you can be notified when the price reaches a level you choose.

Tip: if you plan to buy an ETB, look at the price of the last 7 days, not at a single promotion. In our data the 534.90 zł price from 15 October lasted only one day.

Limits of the data and what we will check next

Our numbers show the lowest price in the shops CardPulse tracks, not transaction prices. We do not know how many units were sold or whether every order was fulfilled.

• Few offers at the start. Percentage drops calculated from a day with 1–2 offers are inflated. That is why we state the number of offers as well.
• Categories and language versions. The Booster Box category mixes English, Chinese, Japanese and Korean editions as well as Mini Tin Displays. The data from Poland, Germany and the US shows it.
• Availability. Availability comes from the shop's last check and can differ from the state at the time of purchase. The price series of 17 October and the offer list of 18 October can drift apart, as in Germany.
• Local prices. We do not convert currencies or compare countries directly, because VAT and shipping costs differ.

In the next report we will check three things: whether the Polish ETB holds 545.99 zł as the number of offers grows, whether an English booster box appears below 900 zł, and how Delta Reign prices behave in the first days after 6 November.

See current offers on the 30th Celebration ETB page or in the set guide, and before buying Delta Reign take a look at the release calendar.
