Frequently Asked Questions
How many Tuckboxes contain a Magnificent Maestros space?
10 Tuckboxes, according to the distributor Ynaris ("10 Tuckboxes per carton"). That makes 30 booster packs, 150 Ultra Rares, and 30 Secret Rare bonus cards, for a total of 180 cards.
What's the difference between a box and a Tuckbox?
A Tuckbox is a box containing 3 booster packs and 3 bonus cards. A box is the original Konami carton containing 10 of these factory-sealed Tuckboxes. The contents of each box are the same.
What's guaranteed in a box?
The contents of each Tuckbox are: 15 Ultra Rares and 3 Secret Rare bonus cards (or Ultra Rare/Starlight Rare cards for the 6 extended artwork cards in Bonus Group 1). Konami does not guarantee any Starlight Rares or Grand Master Rares per box, nor a complete set of all 18 reimagined cards.
Can you find a Grand Master Rare in a box?
It's possible, but nothing is guaranteed. Grand Master Rares are found in booster packs, in the same slots as the reimagined cards. There are only 100 per card for Europe, for a total of 1,800.
What are the pull rates per box?
Konami has not published any pull rates, either per box or per box, for Starlight Rares and Grand Master Rares. The only official figure is the print run: 100 Grand Master Rares per card and per region.
Is the box factory sealed?
Yes. It's the original Konami box, never opened, not 10 Tuckboxes hand-sewn together.
What is the release date and how does pre-ordering work?
The release is scheduled for November 12, 2026 in Europe, according to Konami. The box is shipped as soon as the product is received.
What is the difference between the English and French boxes?
The contents are the same: 10 Tuckboxes, same structure, same rarities, same release date. Only the language of the cards changes. The Grand Master Rares are in English in both versions. In French, the expansion is called Les Maîtres Fantastiques (MAMS-FR).
What is the connection to Magnificent Monsters?
Magnificent Maestros is the sequel. After the cards of the anime's heroes, the set reimagines those of their rivals, adds 21 Toon, Witchcrafter, and Unchained cards, and increases the number of cards to 24 with extended artwork.
Is this case suitable for a retail store or a case opening?
Yes. It's the distributor packaging unit, 10 Tuckboxes per carton, and the original sealed carton serves as proof of origin for the boxes during a filmed opening.
