Pokémon TCG Rotation and Regulation Marks (2026–27)

What is the regulation mark on a Pokémon card?

A regulation mark is a single capital letter printed at the bottom left of a Pokémon card, right next to the set symbol or set code. It exists for one reason: to tell players and judges at a glance whether the card can be used in the Standard tournament format.

English cards first carried a mark in the Sword & Shield set in February 2020, and that first letter was D. The letters A, B and C appeared only on cards released in Asia, which is why the English sequence starts partway through the alphabet. Since then each block of sets has moved one letter along: E and F during Sword & Shield, G for the first Scarlet & Violet sets, H from Temporal Forces (March 2024), I from Journey Together (March 2025) and J from the Mega Evolution sets of 2026.

The letter follows the card rather than the set, so a set can include a handful of cards with a different letter. A card with no letter at all almost always comes from a set before Sword & Shield — anything from the 1999 Base Set to the 2019 Sun & Moon sets. The mark has nothing to do with rarity or value; the rarity symbol sits next to the card number, and our rarity symbols guide covers it.

Which regulation marks are legal in Standard for 2026–27?

H, I and J. The Pokémon Company announced the 2026 rotation on January 9, 2026. It took effect for in-person Play! Pokémon events on April 10, 2026 and on Pokémon TCG Live on March 26, 2026. Cards with the G mark were removed from Standard, and the announcement adds that any future regulation marks will be legal as they arrive.

In set terms, the Standard card pool now starts with Temporal Forces and runs through every later Scarlet & Violet and Mega Evolution set, plus the matching promo cards — the full list is in the next section. The G-mark sets that left were Scarlet & Violet, Paldea Evolved, Obsidian Flames, 151, Paradox Rift and Paldean Fates.

Which sets carry which letters comes from our TCGdex snapshot of every English set; the Standard Legality Checker lists them in full, with card counts.

Which Pokémon sets are Standard-legal right now?

Sixteen main expansions make up the 2026–27 Standard pool as of September 2026, from Temporal Forces (March 2024) to Pitch Black (July 2026). The marks column counts the cards in each set by letter in our TCGdex snapshot — useful because a legal set can still contain a few cards with an older letter.

Notice the G-mark cards inside Temporal Forces and Prismatic Evolutions: being in a legal set doesn’t make a card legal. Read the letter on each card. A G-mark Trainer from those sets is still playable if the same card also exists with H, I or J; a G-mark Pokémon isn’t.

Two newer releases are worth a note. 30th Celebration launched on September 16, 2026; our card data doesn’t have its regulation marks yet, so check the letter on the card — any H, I or J card becomes legal once the set’s waiting period has passed. Mega Evolution—Delta Reign is scheduled for November 6, 2026, with Prerelease events at participating stores from October 24, according to The Pokémon Company’s press release.

How does Standard rotation work?

Standard is the tournament format that rotates, and it deliberately keeps to recent cards. Rather than listing every legal set, Pokémon names the legal regulation marks. When the format rotates, the oldest letter drops out and every card carrying it leaves together — including reprints of older cards that happened to be printed with that letter.

That has happened one letter at a time since the marks were introduced. Here is how the cut-off has moved, according to Bulbapedia’s season records:

Pokémon announces a rotation ahead of time — the 2026 one came out three months before it took effect — and publishes the date for events and for Pokémon TCG Live separately. New sets join the format continuously: the announcement says new cards must wait before they’re tournament-legal, typically two weeks after release. If a set came out last week, check the event’s details before you build around it.

What are the exceptions to the regulation mark rule?

Three exceptions cover most of the questions people bring to the table.

Basic Energy is always legal

Basic Energy cards — the plain Grass, Fire, Water and other Energy with no rules text — carry no regulation mark and are legal in every format, whatever set they came from. Special Energy cards are different: they have text, carry a mark and follow the normal rules.

Reprinted Trainers carry over

If a Trainer card with the same name and text has been printed with a legal mark, older prints of that Trainer can be used too. Pokémon’s own example in the 2026 announcement is Rare Candy: the Sun & Moon version, which has no mark, is still playable because the Rare Candy in the Mega Evolution set has an I mark. Pokémon points players to the Play! Pokémon Tournament Rules Handbook for the fine print.

Pokémon cards don’t carry over

The allowance doesn’t extend to Pokémon. A Pokémon with a rotated mark can’t stand in for a functionally identical Pokémon with a legal mark — you need the H, I or J print itself. For Special Energy reprints, the announcement’s wording covers older unmarked versions of legal cards, but the worked example is a Trainer, so confirm with the handbook or your event organizer.

The ban lists

A card can also be removed by name. As of September 2026 no cards are listed as banned in 2026–27 Standard. Expanded has a short ban list of specific cards — 26 entries, plus one card banned only on Pokémon TCG Live — which our legality checker reproduces in full. Pokémon’s own list lives on Play! Pokémon’s banned card page; check it before a big event.

What happens to rotated Pokémon cards?

Nothing happens to the cards themselves. Rotation only changes which cards can go in a Standard tournament deck. A rotated card is still:

• Legal in Expanded, if it was printed in the Black & White series (April 2011) or later. Every card with a regulation mark qualifies, since marks start in 2020.
• Fine for casual play. At home or at a friend’s house you can agree to use anything.
• The same card to a collector. Rotation doesn’t change a card’s printing, rarity or condition, which is what collectors pay for.

What does shift is demand from players: a deck staple that rotates is needed by fewer Standard decks. Pokémon TCG Live is built around Standard too — it gives players access to every card currently in the format.

If rotation leaves you with a binder of cards you no longer play, that’s a common moment to sell or trade. Text photos to (760) 453-6389 and we’ll tell you what we’d offer in cash or trade credit, based on recent sold prices for the exact printing and condition — or see how selling works.

How do you check if a Pokémon card is legal?

1. Find the letter. Look at the bottom left corner, next to the set symbol or code. No letter usually means a pre-2020 card.
2. Check the card type. Basic Energy is always legal. Pokémon need an H, I or J themselves. Trainers can borrow legality from an H, I or J reprint of the same card.
3. For an older Trainer, search the exact name. If a print with the same name and text has a legal mark, your copy is playable.
4. For Expanded, find the set. Black & White (2011) or later is in. Our list of every English set shows each set’s symbol, code and release date.
5. Check the ban lists for anything you’re unsure of.

The Standard Legality Checker runs those steps for you: pick the letter and card type, answer at most two follow-up questions, and it prints every rule that applied along with its source. If you can’t read the set symbol, the set code finder turns the three-letter code on newer cards into the set name.

What's the difference between Standard and Expanded?

Both formats use 60-card decks and the same rules of play. They differ in which cards you may use and how often they change.

For a new or younger player, Standard is the format to learn first: it’s the one Pokémon TCG Live is built around and the one the rotation announcements cover. Our parent’s guide covers the ways to learn, including the free Pokémon TCG Live app.

What should you buy if you want to play Standard?

Buy from the legal sets. Packs, Elite Trainer Boxes and bundles from Temporal Forces onward hold H, I and J cards, and because the oldest letter is always the one that rotates, cards with the newest letters (I and J, mostly the Mega Evolution sets) have the most Standard life left. Sealed product from the rotated G-mark sets is still fun to open for a collection, but it won’t build a Standard deck.

To finish a deck, buying the exact singles you need saves opening pack after pack hoping to pull them. When you shop for singles, check the regulation mark in the listing photo — two prints of the same Trainer can have different letters, and for a Pokémon only the H, I or J print counts. The What’s in the Box tool shows how many packs each sealed product holds if you’re comparing prices.
