Which One Piece cards can you play in Standard?
One Piece Card Game formats and blocks: what buyers need to know
If you're buying One Piece cards or sealed product to play at events, one small number decides whether they're legal: the block number in each card's bottom-right corner. Here's what each format allows now, which sets carry which number, what leaves next, and how to check before you buy. This covers Bandai's official rules for the English game; always confirm the format with the event's organizer.
In short
- Standard allows cards with block number 2 or higher from April 1, 2026 to March 31, 2027. Block 1 cards (OP-01 to OP-04) aren't allowed (Bandai).
- Block 2 leaves Standard in April 2027 under Bandai's published schedule. That's OP-05 to OP-08 and EB-01.
- Extra Regulation allows every card released so far, minus one shared ban list.
- Official events in North America use English cards only, so Japanese product is for collecting, not for those tournaments.

Sources and notes
Bandai's official rules for the English game. Store events, Store Championships and Regionals use Standard unless the listing says otherwise; Extra Regulation has its own events, such as the Extra Grand Battle (Bandai, Jan 9, 2026). Last verified October 15, 2026.
Find the block number
Block numbers are "printed in the lower right corner of each card", and Bandai uses them to decide which cards are eligible for official tournaments (Bandai). The number sits in a small circle right after the card number and rarity.

Same spot on every card: the number in the circle after the rarity. Card images from Bandai's official card list, shown as Bandai publishes them (marked SAMPLE). ©E.O./S., T.A., as printed on the cards. Status as of October 15, 2026.
Which sets carry which number
Block numbers follow the release year, about four booster sets each. Bandai's examples: "booster packs 1 to 4 being Block 1, booster packs 5 to 8 being Block 2" (Bandai). Later blocks don't split evenly, so here is what the cards themselves show.

- 2OP-05 to OP-08, EB-01Standard until Mar 31, 2027

Sources and notes
Our diagram. Read from the leader cards of each set in Bandai's card list on October 14, 2026. Starter decks carry their own year's number too (ST-10 shows 2, ST-21 shows 3, ST-29 shows 4, ST-31 shows 5), so check the deck before buying it to play.
What leaves next
Standard keeps "approximately 3 years' worth of the latest cards". For April 2027 to March 2028, Bandai's published plan allows blocks 3 to 6, so block 2 leaves. Extra Regulation keeps every block (Bandai). Bandai can still move individual cards; we update this page when it does.
Some cards stay legal whatever the number.
- Super Parallel Rares and cards that share their card number stay legal in Standard "regardless of reprints". New ones print with an X instead of a number (Bandai's list). See parallel.
- Fifteen older cards count as block 4, legal in Standard until March 31, 2029, whatever number is printed on them (same list).
- A reprint with a newer number makes "all past illustrations" of that card usable (Bandai).
Which format am I playing?
Checking a card, step by step
- Read the event listingStandard unless it says Extra Regulation.
- Standard? Check the number2 or higher, or X, in the bottom-right corner.
- Check the ban listIt applies in both formats.
- Brand-new set?Casual store events: on release. Store Championships and up: 7 days later.
Buying with legality in mind
- OP-01 to OP-04 booster boxes now open block 1 cards: playable in Extra Regulation, not Standard.
- OP-05 to OP-08 and EB-01 are Standard-legal until March 31, 2027 under the current plan; after that, Extra Regulation only.
- Language matters. Players in North America "must use English language cards" for their Leader and main deck at all tournament events (Tournament Rules Manual). Japanese imports won't work at those events.
- New sets are legal at casual store events on release day, prerelease included, and at Store Championships and bigger events 7 days after release (same manual).
- Prices and release dates for current sets are in our One Piece buying guide.
