Pokémon launched its premium Elite Trainer Box with Chilling Reign in 2021. It promised 10 booster packs. It contained 8. Somehow, that was only the beginning.
THE ETB RABBIT HOLE · PART 2 OF 5 · LAST REVIEWED AUGUST 2026
By Pikajo | Camp Onion
Short on time? There's a quick-fire FAQ at the bottom.
Last week, we started at the beginning.
Plasma Storm. 2013.
7 booster packs. No sleeves. No promo. Just a useful box full of Pokémon TCG bits that nobody yet realised we'd still be talking about 13 years later.
Then ETBs evolved.
Sleeves arrived. Promos appeared. Hidden Fates gave us the stained-glass birds. Champion's Path put Charizard on everything and behaved exactly as you'd expect a Pokémon product with Charizard on everything to behave.
By the end of 2020, the humble Pokémon Elite Trainer Box wasn't quite so humble anymore.
So Pokémon decided it needed a posher one.
More packs. Better accessories. Exclusive presentation.
The Pokémon Center Elite Trainer Box was born.
There was just one small issue.
It was supposed to contain 10 booster packs.
It contained 8.
Welcome back to The ETB Rabbit Hole.
This week, things go wrong.
What was the first Pokémon Center ETB?
The first Pokémon Center-exclusive Elite Trainer Boxes were released for Sword & Shield: Chilling Reign in June 2021.
There were 2 versions:
Ice Rider Calyrex and Shadow Rider Calyrex.
The standard Chilling Reign ETBs contained 8 Chilling Reign booster packs.
The new Pokémon Center versions were supposed to contain 10, alongside upgraded accessories including metal damage-counter dice and a collectable Calyrex coin.
The idea was simple.
Standard ETB: the normal retail version.
Pokémon Center ETB: the posher sibling.
More packs. Premium bits. Pokémon Center exclusive.
Collector brain activated.
Except launching a premium version only really works if somebody remembers to put the premium bit inside.
Before we get to that, though, there's a strange little branch of the ETB family tree we need to visit.
Before Pokémon Center ETBs, we got ETB Plus
In late 2020, Pokémon had already started experimenting with a premium Elite Trainer Box.
Enter the Sword & Shield Elite Trainer Box Plus.
There was a Zacian version and a Zamazenta version.
Each contained 12 booster packs:
- 3 Sword & Shield
- 3 Rebel Clash
- 3 Darkness Ablaze
- 3 Vivid Voltage
You also got premium metal accessories and either the gold SWSH076 Zacian V or SWSH077 Zamazenta V promo.
But here's the interesting bit.
North America didn't get these 2 ETB Plus products in the same form. Zacian and Zamazenta were combined there into the Sword & Shield Ultra-Premium Collection.
THE TINY DETAIL
That means UK and European collectors can own completely legitimate ETB products that don't fit neatly into a checklist written from an American perspective.
They were unusual for another reason too.
Rather than being built around a single expansion, they contained packs from 4 different Sword & Shield sets.
Pokémon was already messing with its own ETB formula.
Then came Chilling Reign.
And somebody messed with it a little too much.
18 June 2021: the Pokémon Center ETB arrives
Chilling Reign launched with standard Ice Rider Calyrex and Shadow Rider Calyrex Elite Trainer Boxes containing 8 booster packs.
Alongside them came something new.
The first Pokémon Center Elite Trainer Boxes.
They were intended to contain 10 packs, 2 more than the ordinary ETBs.
People ordered them on that basis.
Then Pokémon contacted customers.
There had been a manufacturing error.
The boxes didn't contain 10 booster packs.
They contained:
*8*
Exactly the same number as the standard ETB.
An absolutely magnificent start to a new premium product line.
Pokémon had forgotten the extra packs
I should be fair here.
Nobody literally forgot to put 2 boosters into individual boxes.
This was a manufacturing error affecting the product itself.
But that doesn't make it much less funny.
Pokémon had created a premium Elite Trainer Box. One of its advertised upgrades was 2 additional booster packs.
And then the product was manufactured without them.
There wasn't a secret corrected version waiting behind it either.
The Chilling Reign Pokémon Center ETBs were manufactured with 8 packs, and Pokémon told affected customers it couldn't replace them with a version containing 10.
So Pokémon did the next best thing.
It apologised.
The apology
Affected customers who kept their orders were offered a $10 refund plus applicable taxes on each affected box.
That's not all they got.
Pokémon also promised:
2 Chilling Reign booster packs
Galarian Articuno V 058/198
Galarian Zapdos V 080/198
Galarian Moltres V 097/198
The extra products were sent separately to the original delivery address.
Which means the first Pokémon Center ETB didn't merely become notable because it was first.
Its launch came with a manufacturing error, a refund and a little bundle of Pokémon compensation.
Not quite the grand entrance you'd plan.
Very memorable, though.
ONE FOR THE COLLECTOR NERDS
There's something else I like about this.
The compensation wasn't inside the ETB.
It was sent separately.
So the 8-pack configuration isn't a damaged or incomplete version of the Pokémon Center Chilling Reign box.
That's how the product was manufactured.
Which leads us to...
So is an 8-pack Chilling Reign Pokémon Center ETB incomplete?
No.
This is worth remembering if you ever look at buying one sealed.
The Pokémon Center Chilling Reign ETBs were manufactured with 8 booster packs.
So don't find one, read that it was originally advertised with 10 and immediately conclude somebody has:
- opened it,
- stolen exactly 2 boosters,
- somehow resealed the whole thing,
- preserved it for 5 years,
- and finally listed it specifically to ruin your Tuesday.
8 packs is how the product was manufactured.
The compensation was supplied separately.
The mistake became part of the box's history.
Pokémon Center ETBs had arrived.
Slightly broken.
But they'd arrived.
UK collectors weren't invited yet
Here's the bit that tends to disappear when this history is told from the US.
If you're in Britain and wondering why everyone didn't simply order these early boxes from Pokémon Center UK...
Pokémon Center UK didn't exist yet.
Not the permanent online shop we use today.
Chilling Reign arrived in June 2021.
Evolving Skies followed in August.
Celebrations arrived in October.
The Pokémon Center UK website didn't soft-launch until 9 December 2021, with the full UK launch announced later that month.
So those first Pokémon Center ETBs have a different history for British collectors.
Today we can go onto Pokémon Center UK, find the latest Pokémon Center ETB, watch it sell out and begin the traditional ritual of refreshing the page despite knowing perfectly well what SOLD OUT means.
In summer 2021?
Nope.
The boxes existed.
Our Pokémon Center didn't.
Thanks, Pokémon.
And then came Evolving Skies
27 August 2021.
Oh dear.
Evolving Skies.
Eeveelutions. Rayquaza.
And a certain Umbreon that has since caused grown adults to look at pieces of cardboard with expressions normally reserved for mortgage applications.
There were 2 standard Evolving Skies ETB designs, splitting the Eeveelutions between them.
The ordinary ETBs contained 8 Evolving Skies booster packs.
The Pokémon Center versions contained:
10.
And this time...
all 10 were actually there.
Character development.
The Pokémon Center boxes also had alternative accessories, including different sleeves, an Eeveelution coin and an Eevee enamel pin.
That pin gives us another tiny bit of ETB history. Contemporary coverage identified it as the first pin included in an Elite Trainer Box.
Another first for the list.
Pokémon had invented a new collecting problem
You could buy the standard Evolving Skies ETB.
Or the Pokémon Center version.
But there were 2 different Pokémon Center designs.
So the question wasn't simply:
Do I want an ETB?
It became:
Which ETB do I want?
Then:
Do I want the Pokémon Center one?
Then:
Which Pokémon Center one?
Then, inevitably:
Oh no. Do I need both?
There it is.
The sealed collector's natural habitat.
Pokémon had turned the Elite Trainer Box into a product with variants.
The packs might be the same, but the product wasn't.
The artwork mattered.
The accessories mattered.
The exclusivity mattered.
And because we're talking about Evolving Skies, Pokémon had chosen a particularly dangerous set with which to demonstrate this.
WAIT, WHAT?
There was still no special Pokémon Center promo
This is one of the biggest differences between early and modern Pokémon Center ETBs.
The Evolving Skies Pokémon Center boxes did not contain a special Pokémon Center-stamped Eeveelution promo.
They didn't contain a guaranteed promo at all.
If you started collecting Pokémon Center ETBs recently, that can feel strange.
Today, the stamped promo is one of the first things collectors look at.
Back then?
The box was the exclusive.
Remember that.
We're going to need it next week.
Then Pokémon had a birthday
8 October 2021.
Pokémon's 25th Anniversary.
Celebrations.
And apparently moderation was cancelled.
The standard Celebrations Elite Trainer Box already contained:
10 Celebrations booster packs
plus
5 additional Pokémon TCG booster packs.
That's 15 packs in total.
There's an important detail here. Celebrations packs contain 4 cards, so we're not talking about 15 conventional full-size expansion boosters.
Still, compare it with the 7-pack Plasma Storm ETB we started this series with.
Then Pokémon Center looked at 15 and apparently thought:
Cowards.
The Celebrations Pokémon Center ETB had 19 packs
Yes.
19.
The Pokémon Center version contained:
13 Celebrations booster packs
plus
6 additional Pokémon TCG booster packs.
That's 19 packs in total.
It also contained the Greninja ☆ SWSH144 promo alongside its other ETB contents.
Let's revisit the family tree.
Plasma Storm, 2013
7 packs.
Celebrations Pokémon Center, 2021
19 packs.
Plasma Storm is somewhere shaking its tiny discontinued deck box in disgust.
Pokémon Center ETBs didn't have a proper recipe yet
And I think this is what makes the early Pokémon Center era so interesting.
It wasn't simply:
standard ETB + 2 packs = Pokémon Center ETB.
Different releases got different extras.
Evolving Skies had the Eevee pin.
Celebrations dramatically increased the number of packs.
Other Sword & Shield releases continued experimenting with things such as deck boxes, special coins, extra sleeves and metal accessories.
Pokémon was figuring it out as it went.
Sometimes you got a pin.
Sometimes you got a deck box.
Sometimes metal bits.
Sometimes Pokémon promised 10 packs and had to send you the missing 2 afterwards.
It's a journey.
But one idea had become clear.
The Pokémon Center version wasn't merely another way to buy the same boosters.
It was becoming a collectable version of the ETB itself.
The really important thing hadn't happened yet
If you buy a modern Pokémon Center ETB, there's one feature we haven't really talked about.
The special Pokémon Center-stamped promo card.
That's because these early boxes didn't have one.
Chilling Reign didn't.
Evolving Skies didn't.
The original premium proposition was the box itself, its additional packs and its exclusive accessories.
Then Pokémon changed something.
It took an ETB promo.
Printed another version.
Added a little Pokémon Center logo.
Same promo number.
Tiny stamp.
How much difference could that possibly make?
We'll find out next week.
Because first, I want to know something.
Your turn: which would you keep?
You're standing in front of 2 sealed Evolving Skies ETBs.
One is the standard version.
One is the Pokémon Center version.
You can keep one sealed.
No selling it tomorrow.
No checking current prices first.
No hiding the other one under your jumper.
Which are you choosing?
Standard ETB or Pokémon Center ETB?
Tell me in the comments, but tell me why too.
Is it the artwork?
The exclusivity?
The contents?
The history?
Or do the words Pokémon Center immediately activate a small part of your brain that whispers:
special one... want special one...
And if you actually ordered one of the Chilling Reign Pokémon Center ETBs in 2021 and received Pokémon's compensation, I especially want to hear from you.
There can't be that many people reading this in the UK who were there for the first Pokémon Center ETB cock-up.
Prove me wrong.
Next week at Camp Onion...
The Tiny Stamp That Changed Pokémon ETBs
A tiny logo.
That's what happens next.
Not a new rarity.
Not a gold-plated booster pack.
Not Pikachu personally delivering your order.
A stamp.
Pokémon takes a promo card, puts a Pokémon Center logo on another copy and adds it to the exclusive ETB.
And collectors care.
A lot.
Next week we're finding out which ETB did it first, why stamped and unstamped cards can have the exact same promo number, how the standard and Pokémon Center ETBs changed, and why that tiny logo gave collectors another thing to chase.
And I've already found some things in that story that I didn't know before starting this series.
So if you thought 2 missing booster packs were unnecessarily complicated...
wait until we start talking about identical card numbers.
See you next week.
