Supreme Darkness Set Guide

Overview

Supreme Darkness is the first core booster set of 2025. Its 101 cards break down into 50 Commons, 26 Super Rares, 14 Ultra Rares and 10 Secret Rares, plus 25 Quarter Century Secret Rares: one for every Ultra and Secret Rare, and one card printed only at Quarter Century Secret Rare.

All 101 cards are new, first released with the set on January 23, 2025. Some have been reprinted since, in products such as Magnificent Monsters, Rarity Collection 5 and Legendary Modern Decks 2026.

The set spreads across many themes. Mitsurugi gets seven cards and Evil HERO six monsters plus three Dark Fusion support cards, Argostars, Materiactor and Crystron get five each, and there are smaller runs for Azamina, Gladiator Beast, Tenyi and Speedroid.

Cards and rarities

Supreme Darkness has 101 set codes, each starting SUDA-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.

The 24 Ultra and Secret Rares count again in the Quarter Century Secret Rare row, which is why the rows add up to 125 printings for 101 set codes. 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.

Archetypes

Mitsurugi and Evil HERO get the most cards in Supreme Darkness. Azamina and Argostars get smaller packages, each with monsters and Spells or Traps of its own.

Ame no Murakumo no Mitsurugi

SUDA-EN092

A Ritual Monster Summoned with Mitsurugi Ritual. When Special Summoned it can destroy every monster your opponent controls, and when it is Tributed it searches a Mitsurugi card and can Special Summon itself.

Evil HERO Neos Lord

SUDA-EN031

A Fusion of Elemental HERO Neos (or a Fusion Monster that mentions it) and an Effect Monster, Special Summoned with Dark Fusion. It cannot be destroyed by battle or card effects, and once per turn, when it is Special Summoned or a monster is sent to your opponent's GY, it takes control of one of their face-up monsters.

Evil HERO Dead-End Prison

SUDA-EN002

Special Summons itself from your hand while you control a Fusion Monster that must be Special Summoned with Dark Fusion. It sends a HERO monster from your Deck to the GY, then can stand in for one named material when you Fusion Summon a HERO that turn.

Elzette, Azamina of the White Forest

SUDA-EN008

Reveal it to Special Summon a White Forest or Azamina monster from your hand, or Fusion Summon an Azamina Fusion Monster in your Main Phase. Sent to the GY as Synchro Material, it searches a Sinful Spoils card.

Saint Azamina

SUDA-EN036

A Fusion of a Level 6 or higher Fusion Monster and Synchro Monster. Your opponent cannot target it, or cards on their own field, GY or banishment, with card effects, and the turn it is Fusion Summoned it can Special Summon a Level 9 or lower Azamina monster from your Deck or Extra Deck.

Argostars - Glorious Adra

SUDA-EN010

When Normal Summoned, your opponent cannot respond to your Continuous Traps for the rest of the turn. It can banish itself from the field to place up to 2 Argostars Continuous Traps from your hand or Deck face-up.

Cards worth knowing

Four more cards from the set. Two of them, Mulcharmy Meowls and A Bao A Qu, the Lightless Shadow, are not tied to an archetype.

Mulcharmy Meowls

SUDA-EN025

If you control no cards, discard it to draw a card each time your opponent Special Summons from a GY or banishment this turn. In the End Phase, your hand is cut back to the number of cards they control plus 6.

A Bao A Qu, the Lightless Shadow

SUDA-EN049

A Link-4 for 2+ monsters, including a Fiend. In the Main Phase it can discard a card to destroy 1 card on the field or to Special Summon a LIGHT or DARK monster from your GY, and in your Standby Phase it draws for each Monster Type in your GY, then puts the same number back.

Primite Dragon Ether Beryl

SUDA-EN015

When Normal Summoned it Sets a Primite Spell/Trap from your Deck. Tribute it to send a Normal Monster from your Deck to the GY, and it returns to your hand in your Standby Phase if you have a Normal Monster on the field or in the GY.

Poseidra, the Storming Atlantean

SUDA-EN016

Special Summons itself by sending another WATER monster from your hand or field to the GY. When Summoned it sends an Atlantean or Mermail monster from your Deck to the GY, then returns a card your opponent controls to the hand.

The chase card: Paladins of Bonds and Unity

Paladins of Bonds and Unity

SUDA-EN000

Rarity Quarter Century Secret Rare

Set code SUDA-EN000

1st Edition market price, September 30, 2026 $162.63

The Quarter Century Secret Rare Paladins of Bonds and Unity (SUDA-EN000) is Supreme Darkness's chase card. It was $162.63 on September 30, 2026, a little more than twice the next card, the Quarter Century Secret Rare Primite Dragon Ether Beryl at $75.19.

It is a Level 12 Synchro Monster for 1 Tuner and 1+ non-Tuners with 2500 original ATK and DEF. Your opponent cannot target it with card effects or destroy it with them, and once per turn, while your opponent has 25 or more cards in their GY, it can negate a Spell Card's activation and destroy that card.

It is the one card in the set printed only at Quarter Century Secret Rare, so Supreme Darkness has no cheaper version of it. The catalog lists no other printing of the card.

Playing it

No Supreme Darkness card is on the Forbidden & Limited List as of October 1, 2026, so a deck can run three copies of any of them.

The Mitsurugi cards are Reptiles that act when they are Tributed. Mitsurugi no Mikoto, Kusanagi and Saji each have an effect when Tributed and can be Tributed in place of another Reptile that would be destroyed, and Mitsurugi Ritual and Mitsurugi Prayers give you ways to Tribute them on your own terms.

The Evil HERO cards are built around Dark Fusion. Evil HERO Infernal Rider adds Dark Fusion from your Deck or GY, Evil Assault can return it from the GY, and Dark Contact Fusion Summons a Dark Fusion monster by shuffling its materials from your field, GY or banishment into the Deck.
