Nephthys Deck #769745 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 14 / Side 0 — status: Illegal. 9 violation(s).

Identity & game plan

• Win condition: Hand of Nephthys (1 copy) tributes itself plus one other monster to Special Summon Sacred Phoenix of Nephthys (1 copy), then Phoenix's GY effect destroys Spells and Traps (Inferred, card text verified); Zaborg the Thunder Monarch (2 copies) Tribute Summon destroys a monster; Black Luster Soldier - Envoy of the Beginning (1 copy) is a 3000 ATK beater that needs LIGHT and DARK monsters banished from the GY (Inferred)
• Turn 1 (going first): Open Hand of Nephthys plus a second monster, Tribute into Sacred Phoenix, and use Phoenix plus removal spells to clear the opponent's backrow. Probability of at least one Hand of Nephthys in a 5-card opening hand is about 0.09 (Inferred)
• Turn 2 (going second): Six-card hand with the same single-copy engine; probability of Hand of Nephthys in the opening hand is about 0.11. Removal (Mystical Space Typhoon, Nobleman of Crossout, Heavy Storm, Mind Control) is the main interaction (Inferred)
• Recovery: Sinister Serpent and Sangan recover monsters from the Deck or GY, and Sacred Phoenix can return from the GY after a card-effect destruction. Each recovery route is a single copy (Inferred)
• After siding: No Side Deck is registered (side_count 0), so no post-side plan exists for a best-of-3 format

Why it scores here

This list is Illegal in OCG: four Forbidden cards (Pot of Greed, Graceful Charity, Delinquent Duo, Cyber-Stein, Amazoness Archer, Trap Dustshoot x2) plus Solemn Judgment x3 and Reinforcement of the Army x2 exceed their limits, so the structural score is shown as a theoretical read and capped by 6 points. The deck's engine is thin: the only Nephthys-to-Phoenix line is one Hand of Nephthys and one Sacred Phoenix, giving roughly a 9 percent chance of the starter in an opening 5-card hand. Its 14 Fusion Monsters have only one legal enabler (Metamorphosis, 1 copy) because Cyber-Stein is Forbidden, so most of the Extra Deck is dead. The removal and spell density (27 removal-text cards) gives the list real interaction, which is the main reason it scores above a pure brick. Popularity and archetype usage stats were not counted, and the score was not built by averaging card scores; the 2.9 percent exact archetype purity and missing combo data were penalised instead.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 32, Going First ≈ 27, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 25. Modifiers: Illegal list cap (-6); Banlist exposure (-2); Single-copy engine (-2); Fusion access dependency (-2). Final formula: Structural 32 → 0.80*32 + 0.20*25 = 31 (Meta provisional), then capped to 25 by the Illegal-legality rule (theoretical/structural read only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.09 · 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

• Real removal density (27 removal-text cards) and layered spell and trap interaction (Verified card text)
• Sacred Phoenix with Hand of Nephthys is a real Special Summon line (Verified card text)
• Zaborg and Black Luster Soldier give high-ATK pressure on single-copy access (Verified card text)

Weaknesses

• Illegal in OCG: Forbidden and over-limit cards (Verified legality)
• Engine is single-copy and cannot be reached reliably (Inferred)
• 14 Fusion Monsters with one legal enabler; most of the Extra Deck is dead (Verified composition, Inferred access)
• No Side Deck (Verified)
• Archetype purity 2.9 percent; the deck is a mix of unrelated staples (Verified composition)

Critical choke points

• Hand of Nephthys (1 copy) is the only Phoenix enabler
• Metamorphosis (1 copy) is the only legal fusion enabler
• No recovery for the Phoenix line if Hand of Nephthys is drawn with no second monster

Recommended changes

Evidence & confidence

• Verified: Illegal status: over-limit and Forbidden cards listed in legality.violations; Main 56 / Extra 14 / Side 0 counts and the 14-Fusion Extra Deck; Card text for Hand of Nephthys, Sacred Phoenix, Zaborg, BLS - Envoy, Metamorphosis, Solemn Judgment; Archetype purity 2.9 percent
• Inferred: Hand of Nephthys to Sacred Phoenix as the main win route; Hypergeometric starter odds of about 9 percent for a single copy; Going-first and going-second plans; Removal density as the reason for interaction score
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent 1 passcode(s) in CardIDList could not be resolved to a card (counted as main) no win-rate telemetry exists in YGOVN — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered; post-side plan and D12 are unscored in practice
