Based on Konami’s North American product specification, checked November 13. November 13 is its listed general launch and legal date, not verified local stock or dispatch. No physical card, serial, purchase or box opening was tested; manufacturer diagrams were inspected privately and are not republished.
WHY IT MATTERS
Keep card language, regional serial suffix and eligible treatment together. The regional allocation and package-pool descriptions answer different questions and do not establish a chosen card’s pull probability.
Event date: . This article’s publication date is shown separately above.
Keep the serial suffix and distribution group together
Konami’s Magnificent Maestros page describes Grand Master Rares for the 18 reimagined anime cards, numbered 001 through 100. That numbering is not a worldwide limit of 100 copies of each card: the publisher specifies 100 per card for the Americas combined and another 100 per card for markets supplied from Europe, including Europe, Oceania, Africa and the Middle East. Copies in the latter group carry an E after the serial number.
The page’s prose uses a 1,800-card figure before describing the two allocations. Its manufacturer map labels 1,800 English Grand Master Rares for the Americas and 1,800 for EMEA and Oceania. Keep the regional scope beside that figure rather than presenting 1,800 as an unqualified worldwide total. The serial text and suffix should remain visible in photographs used to identify an offered copy.
All Grand Master Rares are described as English-language cards, including those found in French, German, Italian, Portuguese or Spanish packs. The language on a sealed wrapper therefore does not, by itself, identify the language of this particular target. Record the card language separately from the pack language and distribution group.
Extended art is a broader target than Grand Master Rare
The product has extended-art versions of 24 cards, but only the 18 reimagined cards receive Grand Master Rare versions. The six additional extended-art reprints do not. A listing that says only extended art leaves the intended treatment unresolved; it should not be upgraded to a numbered Grand Master Rare in a checklist without evidence.
The package route differs too. Konami places the 18 reimagined extended-art cards in the foil-wrapped packs, while the six additional extended arts can appear only among the three cellophane-wrapped cards supplied with a box. Those six are described as Ultra Rare or Starlight Rare. Choosing a target starts with the eligible card group and treatment, rather than assuming every extended-art version comes from the same part of the package.
Read the bonus-pool exception before assuming three identical rarities
The page’s short contents list says three five-card packs plus three Secret Rares with a chance to upgrade to Starlight Rare. Its detailed bonus diagram adds a qualification: Pool 1 also includes the six extended-art reprints as Ultra Rare or Starlight Rare. Retain both statements when comparing a package; the summary alone should not erase the Pool 1 treatment exception.
The regular-pack diagram assigns one card from each of Pools A through E to each five-card pack. The bonus diagram instead assigns one card from each of three numbered pools. Those are different selection structures. Neither the regional numbering nor a pool’s size supplies an individual pack probability for a chosen card; the page gives no numerical Grand Master Rare pull rate.
Use the North American dates as dates, not a stock check
Konami’s North American page lists November 11, 2026 for the Official Tournament Store launch and November 13 for the general launch and tournament-legal date. This guide records those specifications on November 13 without claiming that a particular retailer has received a box or that an order will ship today. The page’s original publication date is unknown.
For an offered Grand Master Rare, retain the product name, actual card name, English language, treatment, complete serial including any E suffix, condition and source photographs. For a sealed opening plan, record the relevant pack or bonus-pool route separately. This report has not opened a box, inspected a physical card, authenticated a serial or established a resale value.
