Opening Data: 21 Boxes of Chaos Origin
All opening data on this page is from the Japanese OCG version of Chaos Origin. Both the Japanese OCG and English TCG releases share the Chaos Origin name — this guide covers the OCG product only. Box structure, pull rates, and rarity names reflect Japanese OCG specifications: 24 packs per box, 9 cards per pack, with a Plus 1 Expansion Pack included per box. TCG pull rates will differ.
The data below is drawn from two documented Japanese OCG opening sessions — a 9-box opening and a full carton (12 boxes) opening — totalling 21 booster boxes and 504 main booster packs. Chaos Origin released on 26 April 2026 in Japan at a box price of 5,940 yen.
Session 1: 9-box opening
- 9 booster boxes (216 packs)
- Prismatic Secret Rares: 3 (all from main booster packs)
- Secret Rares: consistent ~2 per box across all 9 boxes
- Quarter Century / Relief treatment cards: approximately 1 per box
- Plus 1 Expansion Pack: 1 per box (9 bonus packs)
Session 2: 1 carton (12 boxes)
- 12 booster boxes (288 packs) plus 12 Plus 1 Expansion Packs
- Prismatic Secret Rares: 8 total (main + expansion packs combined)
- Over-frame Prismatic Secret Rare: 1
- Ultra Rares distributed broadly — no reported dry boxes
Combined hit summary
- Total Prismatic Secret Rares: 11 across 21 boxes
- Over-frame Prismatic: 1 across 1 carton (12 boxes)
- Secret Rares: ~2 per box consistently
- Notable Prismatic pulls: Black Chaos Sword Master (×2), Aleister the Invoker, Sacred Beast cards
Key takeaway: Prismatic Secret Rare distribution was relatively consistent across both sessions — approximately 1 per 3 boxes from main packs, with expansion packs contributing additional pulls. The Over-frame Prismatic appeared once per carton, consistent with its status as the set's ultra-rare treatment across only 4 card types.
Chaos Origin Pull Rates by Rarity
Konami does not publish official Yu-Gi-Oh pull rates. The figures below are derived from documented community opening data. Session-to-session variance is real — treat these as averages, not guarantees.
| Rarity | Est. Per Pack | Per Box (24 packs) | Per Carton (12 boxes) | Notes |
|---|---|---|---|---|
| Over-frame Prismatic Secret Rare | ~1 in 288 | ~1 in 12 boxes | ~1 per carton | Only 4 types in set; rarest treatment |
| Prismatic Secret Rare | ~1 in 72 | ~1 per 3 boxes | ~4 per carton (main packs) | 24 types in set; top chase rarity |
| Secret Rare | ~1 in 12 | ~2 per box | ~24 per carton | Very consistent; effectively guaranteed ×2 |
| Ultra Rare | ~1 in 6 | ~4 per box | ~48 per carton | Consistent; no dry reports |
| Super Rare / Rare / Common | Remainder | Bulk of box | — | Fills remaining pack slots |
Comparing to Ascended Heroes (Pokemon TCG)
Collectors familiar with Ascended Heroes pull rates will notice a meaningful structural difference: Chaos Origin's top rarity (Prismatic Secret Rare at ~1 per 3 boxes) is considerably more accessible than Ascended Heroes' SIR rate (~1 per 3–4 boxes). On the surface the numbers look similar — but the key difference is variance. Yu-Gi-Oh Prismatic Secret Rare rates are more consistent box-to-box because the set structure guarantees hits more predictably. Ascended Heroes SIR sessions of 0-in-100 packs are common; a Chaos Origin box opening of 9 boxes with 3 Prismatics is considered a typical result.
The financial reality of chasing a specific Prismatic
- Goal: Pull the Black Chaos Sword Master Prismatic Secret Rare (1 of 24 Prismatics)
- Avg packs per Prismatic: ~72 (main packs only)
- Avg packs per specific Prismatic: ~1,728
- Box cost (24 packs): ~SGD $75–$90 at Singapore retail
- Expected spend to hit specific Prismatic: SGD $5,400–$6,500+
- Buy it outright: SGD $80–$200 (depending on the card)
- Opening to chase a specific Prismatic is an extremely expensive strategy. Buy singles.
Over-frame Prismatic Secret Rare: How Rare Is It?
The Over-frame Prismatic Secret Rare is a special treatment introduced alongside Chaos Origin's Plus 1 Expansion Pack system. Only 4 card types in the entire set have this treatment — making it categorically rarer than a standard Prismatic Secret Rare.
What makes it different
- Artwork extends beyond the standard card frame border — the 'over-frame' effect
- Full prismatic foil treatment across the entire card surface
- Only 4 variants exist in Chaos Origin (vs 24 standard Prismatic types)
- Can appear in both main booster packs and the Plus 1 Expansion Pack
- Confirmed at approximately 1 per carton (12 boxes) from opening data
| Treatment | Types in Set | Est. Rate (main packs) | Per Carton |
|---|---|---|---|
| Standard Prismatic Secret Rare | 24 types | ~1 per 3 boxes | ~4 |
| Over-frame Prismatic Secret Rare | 4 types | ~1 per 12 boxes | ~1 |
The carton opening produced 1 Over-frame Prismatic from the full 12 boxes. At this rate, a collector buying individual boxes has approximately an 8% chance of hitting one Over-frame Prismatic per box purchased — roughly comparable to pulling an SIR from a single Ascended Heroes booster box, which sits around a 25–33% chance per box at community-estimated rates.
Plus 1 Expansion Pack Explained
Each Chaos Origin booster box ships with one Plus 1 Expansion Pack — a bonus pack separate from the standard 24 booster packs. This is not a new concept in OCG, but Chaos Origin represents a meaningful upgrade to the previous 'Plus 1 Assist Pack' format.
What changed from the Plus 1 Assist Pack
- Previous Assist Packs contained Ultra Rares only — widely criticised as low value
- The new Expansion Pack includes Prismatic Secret Rares in the pull pool
- Over-frame Prismatic variants can appear in Expansion Packs
- Secret Rares are also possible from Expansion Packs
- Community reception has been significantly more positive than the previous format
Expansion Pack pull rates (estimated)
- Prismatic Secret Rare: possible — confirmed pulls from expansion packs across carton opening data
- Secret Rare: confirmed in Expansion Packs
- Ultra Rare: base rate; most Expansion Packs land here
- Over-frame Prismatic: possible but very rare — treat as a bonus if it appears
A carton (12 boxes) generates 12 Expansion Packs. In the documented carton opening, these 12 Expansion Packs contributed meaningfully to the total Prismatic count. Treat the Expansion Pack as a genuine bonus pull opportunity rather than dead packaging — it is a real improvement over previous OCG supplemental packs.
Chaos Origin: Top Chase Cards
Chaos Origin is one of the most thematically broad OCG sets in recent memory — spanning Chaos archetypes, Sacred Beast support, Magistus, Merffy, Phantom Knights, Elfin Notes, and new themes. The cards most collectors are targeting for Prismatic treatment:
Headline Prismatic targets
- Super Chaos Sword Master Black Chaos — the package card; Prismatic version is the primary chase. Strong effect and iconic artwork combining Dark Yugi with Black Chaos make this the set's standout pull.
- Sacred Beast cards (Hamon, Uria, Raviel) — new support for the three Sacred Beasts arrives with Chaos Origin. All three received significant new cards; Prismatic versions are among the most sought-after pulls.
- Aleister the Invoker (new version) — Magistus / Summoned Skulls archetype receives major new support. Aleister in Prismatic is one of the most consistently desired pulls for competitive play.
- Pot cards — multiple Pot-type spell cards appear in the set. Prismatic Pot reprints are always in demand regardless of the meta; 4 pulls of Pot-type cards were recorded across the 9-box session alone.
Over-frame Prismatic targets (only 4 types)
Only 4 cards in Chaos Origin have the Over-frame Prismatic treatment. Based on the set's theme emphasis, the Over-frame treatment is expected on the highest-profile Chaos archetype cards — likely including Black Chaos Sword Master and at least one Sacred Beast. Confirm via pull reports as community data accumulates.
Competitive vs collector value
Unlike some recent OCG sets where the top Prismatic cards are purely collector items, Chaos Origin has meaningful competitive relevance. Aleister the Invoker, the new Magistus support, and several generic Link monsters (confirmed strong on multiple pulls) have real deck-building value. This dual appeal — competitive utility plus collector demand — is why the set saw unusually aggressive pre-order activity and rapid general-sale sellouts across Japan.
What This Means For You: Practical Singapore Collector Guide
If you want a specific Chaos Origin Prismatic
Buy the single. Black Chaos Sword Master Prismatic and Sacred Beast Prismatic cards will be available from Japanese importers and Singapore sellers. Paying SGD $80–$200 for the card outright is a fraction of the expected cost to pull one specific Prismatic from boxes. Use the tcgTalk price comparison to find current Singapore listings.
If you want to open boxes
Chaos Origin is a genuinely rewarding set to open — Secret Rares come at ~2 per box, making every box feel productive even without a Prismatic. Set a per-box or per-session budget. Buying single boxes gives you a reasonable ~33% shot at a Prismatic per box, with each box also delivering 2 guaranteed Secret Rares. The Plus 1 Expansion Pack adds real variance upside at no extra cost.
If you are buying sealed for investment
Chaos Origin has strong fundamentals for sealed appreciation: iconic artwork, broad thematic coverage (Chaos, Sacred Beasts, Magistus), and a genuine sellout at launch. Boxes that were available at Japan retail (5,940 yen) represent the floor price. Singapore retail will carry a freight and distribution premium. Historical OCG set appreciation on 2–4 year horizons has been positive for popular sets — but do not pay significant above-retail premiums and expect immediate returns.
If you are sourcing from Japan
Chaos Origin was effectively unavailable at general sale across Japan — only pre-orders were fulfilled at most stores. Expect proxy/forwarding service markups or secondary market prices if buying from Japan now. Check Yuyutei and Mercari JP for current box pricing, and factor in consolidation and shipping costs. See our guide to buying from Japan for proxy service options.
Frequently Asked Questions
Is this guide for the OCG or TCG version of Chaos Origin?
Both the Japanese OCG and English TCG releases share the name Chaos Origin. All pull rate data on this page is from the Japanese OCG version. The OCG and TCG versions have different box structures, rarity distributions, and card numbering — pull rates from one do not directly apply to the other. The Japanese OCG version covered here has 24 packs per box, 9 cards per pack, and includes a Plus 1 Expansion Pack per box. If you are buying the English TCG version of Chaos Origin, treat these figures as directional only.
How does Chaos Origin compare to recent OCG sets for pull rates?
Chaos Origin follows the recent OCG structural trend: ~2 Secret Rares per box, ~1 Prismatic per 3 boxes from main packs, and a meaningful Plus 1 Expansion Pack bonus. This is broadly comparable to the previous major release (Blazing Dominion and similar sets), though the Expansion Pack improvements make Chaos Origin feel more rewarding per box than sets using the old Assist Pack format.
Does the Plus 1 Expansion Pack affect the main box pull rates?
No — the Expansion Pack is a separate, bonus pack. Its hits are additive, not redistributed from the main 24 packs. Your main booster box pull rates are unaffected by what appears in the Expansion Pack. Think of it as a free extra pack that happens to have a real Prismatic pool.
Why did Chaos Origin sell out so quickly at general sale?
Several factors converged: the package artwork featuring Dark Yugi and Black Chaos is among the most visually striking OCG packaging in years, attracting both returning collectors and casual buyers. The Sacred Beast support (Hamon, Uria, Raviel) drew nostalgia-driven demand. And an active anime in 2026 has broadly reinvigorated Yu-Gi-Oh interest. Pre-order demand absorbed most allocation before general sale opened.
Is Chaos Origin worth buying in Singapore if boxes are above retail?
At modest above-retail premiums (10–20%), the set remains reasonable for personal opening — the pull experience is solid and competitive demand for Aleister and Magistus support sustains singles values. At large premiums (50%+), the expected value from opening becomes harder to justify. Evaluate: if you want specific singles, buy those singles. If you want the opening experience with a defined budget, set that budget and commit. Do not buy above-retail boxes expecting to profit from opening.
