Magnificent Monsters has no Commons, Rares or Super Rares. Every one of its 126 cards is printed at Ultra Rare or higher, and 46 of them come at two or three rarities.

Its 33 new cards sit mostly at the front of the list. The first 18, MAMO-EN001 to MAMO-EN018, are new cards for established names, among them Dark Magician, the Pharaoh's Servant, Kuriboh - Multiply!, Stardust Dragon - Victim Sanctuary, Number 39: Utopia, Emissary of Light and Decode Talker Integration, and each is printed as Ultra Rare, Starlight Rare and Grand Master Rare. Eight more new cards follow at MAMO-EN021 to MAMO-EN028, one sits at MAMO-EN101, and the last six close the set.

The other 93 cards are reprints. They run from Waboku and Delinquent Duo, first released in 2002, to Gorgon of Zilofthonia, first released in Winner's Pack 2026-2027 this July, and the two Sky Striker spells at MAMO-EN019 and MAMO-EN020 are the most valuable of them.

Cards and rarities

Magnificent Monsters has 126 set codes, each starting MAMO-EN and printed under the artwork on the right. Where a card comes at more than one rarity, every version shares its code, so the table counts set codes at each rarity and a code printed at two rarities is counted twice.

RarityCardsWhat they are
Ultra Rare120Every card except the six new ones at MAMO-EN121 to EN126.
Secret Rare26MAMO-EN021 to EN040 and EN121 to EN126.
Starlight Rare46The first 40 cards and the last six.
Grand Master Rare18The 18 new cards at MAMO-EN001 to EN018, and the set's chase cards.

The 80 cards from MAMO-EN041 to EN120 come at Ultra Rare only. On September 30 the catalog had no price at any rarity for Odd-Eyes Pendulum Dragon of the Four Heavenly Dragons (MAMO-EN013), and seven of the 18 Grand Master Rares had no price yet. Set completion in TurnZero HQ counts the distinct set codes you own against the set's total, so a card printed at two rarities counts once, with an every-rarity count beside it for collectors chasing each version.

The new cards

The 18 Grand Master Rare cards are the new headline cards, and most of them add to an archetype that already exists. Dark Magician, Kuriboh, Elemental HERO, Stardust and Synchron, Gagaga, the Pendulum Magicians and Cyberse each get new support.

Dark Magician, the Pharaoh's Servant, MAMO-EN001

Dark Magician, the Pharaoh's Servant

MAMO-EN001

Its name becomes Dark Magician on the field and in the GY. Once per turn it can reveal a Spell to Special Summon itself from your hand and Set a Spell or Trap that mentions Dark Magician, or discard a Spell as a Quick Effect to destroy all Spells and Traps your opponent controls.

Kuriboh - Multiply!, MAMO-EN002

Kuriboh - Multiply!

MAMO-EN002

Special Summons itself from your hand when your opponent activates a monster effect or attacks. Once per turn it can then add or Special Summon Dark Magician or a 300 ATK/200 DEF monster from your Deck or GY, and can make that opponent's monster's ATK 0.

Stardust Dragon - Victim Sanctuary, MAMO-EN007

Stardust Dragon - Victim Sanctuary

MAMO-EN007

Tribute it as a Quick Effect to negate and destroy a card or effect your opponent activates in response to yours. If one of your monsters was Tributed this turn, banish it from the GY to Special Summon a Stardust Synchro Monster from your Extra Deck.

Favorite HERO Flame Wingman, MAMO-EN005

Favorite HERO Flame Wingman

MAMO-EN005

A Fusion Monster always treated as an Elemental HERO card. It gains 1000 ATK in a battle with a monster that has 2200 or more ATK, and after a monster is destroyed by battle it can Fusion Summon as a Quick Effect.

Number 39: Utopia, Emissary of Light, MAMO-EN010

Number 39: Utopia, Emissary of Light

MAMO-EN010

Can't be destroyed by battle except with a Number monster. Detach a material to save one of your monsters from its first destruction that turn, and when the second attack of a turn is declared it gains 2500 ATK.

Decode Talker Integration, MAMO-EN016

Decode Talker Integration

MAMO-EN016

In the Extra Monster Zone it gains 500 ATK for every other Link Monster on the field and in the GYs, and your opponent can't target it. Once per turn it can Tribute a monster it points to, send a Cyberse monster from your Extra Deck to the GY, and attack monsters twice.

Reprints worth knowing

The reprints cover years of sets. These four carry the most value or do the most general work, and each is printed here at Starlight Rare as well as Ultra Rare.

The chase card: Cyberse Contract Witch

Rarity Grand Master Rare
Set code MAMO-EN018
1st Edition market price, September 30, 2026 $68,000.00

The Grand Master Rare Cyberse Contract Witch was the most valuable printing in Magnificent Monsters on September 30, at a market price of $68,000. The next highest, the Grand Master Rare Stardust Dragon - Victim Sanctuary, was $35,000.

Read those figures with care. At prices this high, a single sale can move the market figure a long way in either direction, so treat it as a rough marker rather than what a given copy will sell for.

The other two printings of the same card sit in a different market. The Starlight Rare was $243.57 and the Ultra Rare $2.22.

Chase cards and prices

These are TCGplayer's 1st Edition market prices on September 30, 2026. Prices for a new set can move a long way in its first months, so treat them as a snapshot. Each card's page shows today's price for every printing. How Yu-Gi-Oh! card prices work →

Playing it

Most of the new cards are support for decks built around their names. Dark Magician, the Pharaoh's Servant counts as Dark Magician on the field and in the GY, the two Favorite HERO Fusion Monsters are always treated as Elemental HERO cards, and Starjunk Synchron can stand in for any Synchron Tuner in a Synchro Summon.

Cyberse Contract Witch reaches furthest. When it is Link Summoned, it trades a Spell from your hand or field for a Ritual Monster from your Deck, and it can Special Summon a monster from your GY that shares a Type with a Ritual, Fusion, Synchro or Xyz Monster it points to but has a different card type.

Four cards in the set were on the Forbidden & Limited List as of October 1, 2026. Delinquent Duo and Sixth Sense are Forbidden, so you can't put them in a deck at all. Phantom of Yubel is Limited to one copy and Dracotail Lukias is Semi-Limited to two.
