Chaos Origins Set Guide

Overview

Chaos Origins is the third core booster set of 2026, after Burst Protocol and Blazing Dominion. Its 100 cards follow the core set pattern of 50 Commons, 26 Super Rares, 18 Ultra Rares and 10 Secret Rares, and 25 of those cards are also printed as Starlight Rares.

Every card in the set is new. The catalog dates all 100 to July 2, 2026, and only three of them, Astrazma Urania, Hyperinvoked Aeon and Pot of Sloth, have been printed anywhere else since, in Winner's Pack 2026-2027.

The center of the set is a Ritual pair. Magician of Dark Chaos - Black Chaos and Black Luster Soldier - Soldier of Light and Darkness are both Ritual Summoned with Light and Darkness Ritual, and ten cards, the Ritual Spell included, belong to that theme. Eleven more support the Sacred Beasts, and Blitzclique and Angelechy each get a theme of their own.

Cards and rarities

Chaos Origins has 100 set codes, each starting CORI-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.

Four cards come at three rarities: Magician of Dark Chaos - Black Chaos, Black Luster Soldier - Soldier of Light and Darkness, The Chaotic Phantasmal Sacred Beasts and Phara the Primordial Goddess are each printed as Ultra Rare, Secret Rare and Starlight Rare. 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

Four themes take up most of Chaos Origins: the Light and Darkness Ritual cards, the Sacred Beasts, Blitzclique and Angelechy. Smaller packages for Invoked and Aleister, The Phantom Knights, S-Force and Melffy fill out the rest.

Magician of Dark Chaos - Black Chaos

CORI-EN027

Ritual Summoned with Light and Darkness Ritual, and unaffected by your opponent's activated effects unless they target it. When Special Summoned it adds a Spell from your GY to your hand, and it can banish 1 card your opponent controls face-down.

Black Luster Soldier - Soldier of Light and Darkness

CORI-EN028

The other Light and Darkness Ritual monster. It can't be destroyed by battle, banishes 1 card your opponent controls when Special Summoned, and after destroying a monster by battle can gain 1500 ATK and attack again.

Sacred Beasts Released

CORI-EN047

Adds 3 Sacred Beast monsters with different names from your Deck to your hand, then you discard 2. Later, you can banish it from the GY to add a Level 10 Pyro, Thunder or Fiend that can't be Normal Summoned.

The Chaotic Phantasmal Sacred Beasts

CORI-EN029

A 5000 ATK Fusion Monster made from 3 Level 10 monsters that can't be Normal Summoned. Up to three times a turn it negates a face-up monster your opponent controls, and the first two times each turn it would be destroyed by a card effect, it isn't.

Surge Blitzclique

CORI-EN011

Reveal it from your hand to destroy a monster on the field and Special Summon a Thunder monster from your hand. While it is on the field, another card destroyed by a card effect lets you add a Blitzclique monster from your Deck.

Angelechy Opening to e4

CORI-EN096

Places an Angelechy Field Spell, Special Summons a Level 2 or 7 Angelechy monster from your Extra Deck, and places another Angelechy monster in your Spell & Trap Zone as a Continuous Spell. If your opponent goes first, you can activate it from your hand in their first Standby Phase.

Cards worth knowing

A few cards outside the main themes do something a wider range of decks can use, within the limits printed on them.

Pot of Sloth

CORI-EN061

Draws cards equal to the number of cards your opponent controls; if that is 2 or more, you place all but one of that many cards from your hand on the bottom of the Deck. You can't activate another Pot of Sloth that turn.

Phara the Primordial Goddess

CORI-EN022

Reveal it with a Spell or Trap, and neither player can respond to cards with that name until the end of the next turn. Special Summoned from the GY, it takes control of the monster your opponent controls with the highest ATK.

Witness of the Ancient

CORI-EN081

A Level 8 Tuner that Special Summons itself if you have a Synchro Monster in your field or GY, then places up to 3 Synchro Monsters in your Spell & Trap Zone and makes an Arc Token with a Level equal to that number.

Zenna's Deceiving Doll Maidens

CORI-EN043

A Link-5 that can use a monster in your hand as material. When Link Summoned it sends a monster from your Deck to the GY, or from your Extra Deck if every material was a monster you controlled.

The chase card: Magician of Dark Chaos - Black Chaos

Magician of Dark Chaos - Black Chaos

CORI-EN027

Rarity Starlight Rare

Set code CORI-EN027

1st Edition market price, September 30, 2026 $489.06

The Starlight Rare Magician of Dark Chaos - Black Chaos is the card Chaos Origins is opened for. At $489.06 on September 30 it was the most valuable printing in the set, and the only one above $400.

Its Ritual partner is close behind. The Starlight Rare Black Luster Soldier - Soldier of Light and Darkness was $305.09, and no other printing in the set reached $140.

The gap between rarities is wide. The Ultra Rare Magician of Dark Chaos was $60.36, and the Secret Rare was $8.95, well below the Ultra Rare.

Chase cards and prices

Every printing in the top eight of Chaos Origins is a Starlight Rare. The two Ritual Monsters lead by a wide margin, and the Starlight Rare Pot of Sloth is the most valuable card outside the set's archetypes.

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

The Light and Darkness Ritual cards are built to find each other. Skull Archfiend of Chaos sends a Ritual Spell to the GY to add a Ritual Monster that spell names, Celtic Mystic Tributes itself to Special Summon a Light and Darkness Ritual monster from your hand, and Light and Darkness Ritual returns itself and another card that mentions it from the GY to your hand.

The Sacred Beasts play differently. Uria, Hamon and Raviel can't be Normal Summoned and must be Special Summoned by a Sacred Beast card's effect, so the deck leans on Sacred Beasts Released to find them and on Summoner of the Sacred Beasts, which Special Summons Sacred Beast monsters from your hand or GY in Defense Position.

None of the 100 cards in Chaos Origins was on the Forbidden & Limited List as of October 1, 2026, so you can run three copies of any of them.
