Limited to 100 serial-numbered cards — that is how Konami’s product pages headline the Grand Master Rare in both LIMIT OVER COLLECTION – THE HEROES – and LIMIT OVER COLLECTION – THE RIVALS -, with an individual serial number stamped on every card.
Yu-Gi-Oh’s OCG has produced premium collection sets before, but nothing structured quite like this pair. In early 2026, Konami released two companion sets about three weeks apart: LIMIT OVER COLLECTION – THE HEROES – (LOCH, February 28) built around the protagonists of the franchise, and LIMIT OVER COLLECTION – THE RIVALS – (LOCR, March 20) built around the characters who stood across the field from them. Both sets introduced the “Overframe” card design, where the illustration breaks out past the card frame, and both carry the serial-numbered Grand Master Rare.
LOCH and LOCR are twin 80-card premium collections (Ultra Rare 38 / Super Rare 42 each, 4 cards per pack, 15 packs per box, ¥385 per pack). The chase mechanic is the serial-numbered Grand Master Rare — Konami’s pages for both sets headline it as limited to 100 serial-numbered cards.
- Konami’s LOCR page carries the same 100-copy serial-numbered Grand Master Rare headline as the LOCH page.
- Sealed LOCH and LOCR boxes are sold out at the time of this update — sourcing requests go through Quick Order.

What Is the Limit Over Collection?
LIMIT OVER COLLECTION is a two-set premium collection series for the Japanese Yu-Gi-Oh OCG, released in early 2026. Rather than pushing a new mechanic or archetype for competitive play, both sets are built around the franchise’s characters — one set for the protagonists, one for their rivals — and around card treatments you can’t get anywhere else.
The two halves mirror each other deliberately:
- LIMIT OVER COLLECTION – THE HEROES – (LOCH) released February 28, 2026, and collects cards imagined around the protagonist characters, with new OCG cards adapted from past anime series, new illustration variants, and versatile, popular cards.
- LIMIT OVER COLLECTION – THE RIVALS – (LOCR) followed on March 20, 2026 — a national holiday in Japan — with the identical structure applied to the rival characters. Its official catchphrase translates to “Break past the limit — unleashed, here and now.”
Both sets share the same skeleton: 80 card types (38 Ultra Rare, 42 Super Rare), sold in packs of 4 cards at ¥385 per pack (tax included) with 15 packs per box. That 4×15 configuration is the standard format for OCG premium collections — it’s the same box structure Konami used for the art-focused QUARTER CENTURY ART COLLECTION in February 2025, which we covered in our QCAC Quarter Century Art Collection guide. Where QCAC was organized around illustration variants, the Limit Over pair is organized around character identity — and it adds two things QCAC never had: the Overframe design and the serial-numbered Grand Master Rare.
If you’re newer to importing Japanese Yu-Gi-Oh product, our Japanese Yu-Gi-Oh cards buying guide explains how OCG sets, rarities, and set codes work — worth reading alongside this one if terms like “Prismatic Secret Rare” are new to you.
Grand Master Rare: 100 Serial-Numbered Cards
The headline of the entire Limit Over Collection project is a new rarity: the Grand Master Rare GMR. Every Grand Master Rare card carries an individual serial number, and Konami’s product pages for both sets headline it as 100枚限定シリアルNo.入り — limited to 100 serial-numbered cards.
Standard chase cards in modern TCG sets are scarce in the sense that pulling one is unlikely, while the print run behind them is not published. A Grand Master Rare puts a figure in the headline instead, and each card’s serial number marks which copy you hold — Konami’s pages say the holder is the only holder of that serial number.
That changes what “owning the card” means in a very literal way:
- Published limit. The 100-copy limit is part of the headline on both product pages.
- Each copy is individually identifiable. Serial numbering means no two cards are interchangeable. Low numbers, meaningful numbers, and the simple provenance of a specific copy all become part of the card’s identity.
- A new rarity. Konami’s pages introduce Grand Master Rare as a new rarity (新たなレアリティ) in this series, alongside the Prismatic Secret, Secret, Ultimate and Collector’s Rare versions.
In each set, 18 Ultra Rare cards have a serial-numbered Grand Master Rare version. Konami’s pages also state that no two cards share a serial number.
Konami’s pages state that each Grand Master Rare is engraved with its own serial number and that, for this reason, exchanges and returns cannot be accepted.
The Overframe Design Explained
The second signature of the Limit Over Collection is the “Overframe” (オーバーフレーム) card design. Konami’s official description is simple: the illustration extends beyond the card frame. Instead of the artwork sitting inside the standard bordered art box, the monster breaks out of it — the character spills past the lines that normally contain it.
It’s a fitting visual for a product literally named “Limit Over”: the cards’ art crosses its own printed limits the same way the set’s theme celebrates characters who did. And because the design is applied to signature character monsters — the aces and the rivals’ counterparts — the effect lands on exactly the cards where a dramatic, frame-breaking pose means the most.
Konami’s pages for both sets describe the same Overframe distribution:
- Ultra Rare: 18 Ultra Rare cards are Overframe cards.
- Prismatic Secret Rare: 18 of the Prismatic Secret Rare versions are Overframe cards.
These are two separate things that both debut in this series. Overframe is a design — art breaking the frame — applied at stated rarities. Grand Master Rare is a rarity — the serial-numbered tier. Don’t conflate them when evaluating singles.

LOCR — THE RIVALS: Full Breakdown
