Ogdoadic/Abhyss Deck #768305 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: ocg

Legality

Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Ritual Summon Mitsurugi monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi) and Ogdoadic/Abyss boards (Aron, Ogdoabyss, Nephilabyss) from recursion-heavy Reptile lines; Link and Xyz closers (Ragnaraika Selene Snapper, Summon Sorceress, Full Armored Utopic Ray Lancer) once the GY and field are populated
• Turn 1 (going first): Search a Mitsurugi or Ogdoadic engine card with Mitsurugi Prayers or Pre-Preparation of Rites (both over the limit as built), then build toward a Ritual or Link line; no sequence was supplied, so this is Inferred from card text
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre and Nibiru to interrupt the opponent's board, then recurse Reptiles from the GY through Nauya, Nunu, Keurse or Derk (Inferred)
• Recovery: Reptile GY recursion (Nauya, Nunu, Keurse, Nephilabyss, Derk) and searchers (Mitsurugi monsters, Ogdoadic Spell/Traps) to rebuild after a single disruption (Inferred)
• After siding: Not assessable: the deck has zero Side Deck cards, so there is no post-side plan

Why it scores here

The deck reliably opens a Reptile engine, since the archetype core (29 copies) has a proxy 97.9% chance of at least one copy in a 5-card opening hand, and 18 searcher-text cards add redundancy (Inferred). Its recursion web (Nauya, Nunu, Keurse, Nephilabyss, Derk) and nine hand traps give it real resilience and interaction, which is why the structural score sits near the middle of the scale. The score is held down by the fact that the list is Illegal in OCG: three cards exceed their copy limits, and a cap applies, so this is a theoretical, structural-only read. The deck has no combo boards, no tournament link and no side deck, so the floor and median output cannot be measured. The score comes from consistency, interaction and recursion on the system, not from averaging card scores, and not from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Combo secondary (about 80/20 on the Midrange profile); Midrange weights used as the base. Structural ≈ 51, Going First ≈ 45, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (-8); No side deck (-4). Final formula: Theoretical cap for Illegal list: 0.80*Structural(51.4) + 0.20*TournamentReliability(35) = 48.1, then context modifiers (-12) = 36; Meta Power null (Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Redundant Reptile recursion (Nauya, Nunu, Keurse, Nephilabyss, Derk) keeps lines alive after disruption (Inferred)
• Nine hand traps plus removal text give strong interaction density on both turns (Inferred)
• Core archetype cards are nearly always present in opening hands (Inferred from the hypergeometric proxy)

Weaknesses

• Illegal as built: three cards over their OCG copy limits (Verified)
• Zero Side Deck cards: no post-side adaptability (Verified)
• Ritual and Link lines depend on Reptile tributes, making sequencing error-prone (Inferred)
• Off-archetype copies (70 of 70 non-exact) reduce coherence of the engine (Verified count)

Critical choke points

• Reptile tribute availability for Mitsurugi Ritual and Ritual Summons (Inferred)
• Dependence on Mitsurugi Prayers or Pre-Preparation of Rites for search, both at copy limit 1 (Verified legality)

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal in OCG: Pre-Preparation of Rites (3 vs 1), Mitsurugi Prayers (3 vs 1), Ash Blossom & Joyous Spring (3 vs 2); Main 56 cards, Extra 14, Side 0; size rules are met; Card text for the listed cards and their role hints; Archetype usage: 25 core cards, 17 present, 68% core coverage
• Observed: No parseable boards and no combo data: observed combo output is absent
• Inferred: Hypergeometric starter and archetype-core access (0.25 per 3-copy card; 0.98 for the archetype core); Interaction density from 9 hand traps and 9 negation-text cards; Recursion-based resilience from Reptile GY effects; Pilotability and sequencing complexity
• Provisional: Meta Power and Matchup Coverage: no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample Zero Side Deck cards: post-side plan cannot be assessed No deck title (title null): deck name taken as null
