Nekroz Deck #714405 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Ritual Summon Nekroz boss monsters for disruption and grind advantage; Rank 4 Xyz pressure via Ryzeal engine and Toadally Awesome
• Turn 1 (going first): Ritual Summon Nekroz of Brionac or Unicore to establish negation; search starters with Avance and ritual spells
• Turn 2 (going second): Hand traps (Ash, D.D. Crow, Impermanence) into board disruption; limited removal access without forbidden cards
• Recovery: Recursion via Nekroz discard effects and GY search; limited—deck depends on live ritual spells
• After siding: No side deck provided; cannot assess post-side coherence

Why it scores here

This deck is illegal in OCG (5 Forbidden cards: Appointer of the Red Lotus ×3, Maxx "C", Harpie's Feather Storm, Bahamut Shark, Herald of the Arc Light) and receives a structural-only evaluation. The deck attempts a Nekroz ritual engine (Brionac, Unicore, Catastor searchers) paired with a Ryzeal Xyz sub-engine, but suffers from core inconsistency: only 4 of 25 archetype-core cards are present (16% core purity), missing critical Magistus and Fairy Tail support. The ritual spell redundancy (Preparation, Kaleidoscope, Divinemirror, Cycle) is strong; hand-trap coverage (14 copies) supports going-second. However, 55-card main deck inflates brick risk, the extra deck is oversized (15 slots, many flex), and combo evidence is absent—no tested board sequences exist. Ritual lines are theoretically sound (discard searchers, multiple boss effects) but unverified in practice. The deck is unplayable as-is and should not be scored for competitive use.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 39, Going First ≈ 44, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 32. Modifiers: Illegality penalty (-11); Missing side deck (-2). Final formula: Illegal deck — capped at structural-only evaluation. Formula: 0.70·Structural + 0.30·TournamentReliability (Meta null; illegality modifier −11; no post-side plan modifier −2). Result: 0.70·39 + 0.30·32 − 11 − 2 = 27.3 + 9.6 − 13 = 23.9 ≈ 28 (rounded, band ±8).

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Ritual spell redundancy (4 copies: Preparation, Kaleidoscope, Divinemirror, Cycle) provides multiple Nekroz summon routes
• Hand-trap suite (14 copies: Ash, Impermanence, D.D. Crow, Evenly Matched, Droll & Lock, Dimension Shifter) supports disruption
• Searcher density (26 copies with 'searcher' text) enables draw acceleration and deck thinning
• Dual-engine design (Nekroz ritual + Ryzeal Xyz) theoretically offers backup lines for disruption
• Nekroz boss effects (Brionac search, Unicore negation, Areadbhair removal) layered interaction

Weaknesses

• Deck is ILLEGAL in OCG: 5 Forbidden cards (Appointer ×3, Maxx C, Feather Storm, Bahamut Shark, Herald of Arc Light)
• Archetype core purity only 16% (4 of 25 core cards present); missing Magistus, Fairy Tail, and key Predaplant support
• 55-card main inflates brick risk; Normal Summon bottleneck with 10 ritual monsters competing for one summon per turn
• No combo evidence: no tested boards, no power-index distribution, no verified ceiling output
• Ritual summoning vulnerability: single choke point on ritual spell availability; no independent backup lines after first ritual disrupted
• Extra deck oversized (15 slots, 2 Forbidden) with many flex cards reducing consistency
• Limited removal without Forbidden cards (Harpie's Feather Storm, Bahamut Shark unavailable); board-wipe weakness
• No side deck: post-side adaptability unmeasurable; tournament reliability compromised
• Ryzeal sub-engine underutilized (5 copies, limited Xyz payoff); Toadally Awesome ×2 but no synergy with ritual core

Critical choke points

• Ritual spell draw is mandatory: if no ritual spell in opening hand/early draws, ritual lines dead
• Forbidden cards present make deck illegal: cannot be played in OCG format without correction
• Avance/Emilia/Shurit synergy requires exact ritual summon conditions (1 Nekroz ritual); failing triggers stalls line
• Hand-trap reliance for going-second; without hand traps in opening 6, board-break capability minimal
• Mereologic Aggregator (Rank 9) and D/D/D Wave High King (Rank 6) are niche slots; core does not naturally generate their levels

Evidence & confidence

• Verified: Legality status: Illegal (5 Forbidden cards: Appointer ×3, Maxx C, Feather Storm, Bahamut Shark, Herald of Arc Light); Main deck size: 55 cards (legal range 40–60); Extra deck size: 15 cards (legal maximum); Archetype core purity: 16% (4 of 25 core cards present); Forbidden card ban field: BanList (OCG format); Card text excerpts: all resolved from deck evidence; Usage statistics available: 34 rows; Nekroz core 16% present, 84% missing
• Observed: Hand-trap density: 14 copies detected (Ash, Impermanence, D.D. Crow, Evenly Matched, Droll & Lock, Dimension Shifter); Searcher text detected: 26 copies with 'searcher' hint tags; Ritual spell count: 4 (Preparation, Kaleidoscope, Divinemirror, Cycle); Rank 4 Xyz count: 6 (Ryzeal Duo Drive, Toadally Awesome ×2, Exciton Knight, Castel, Eclipse Twins, Ryzeal Detonator, Starliege)
• Inferred: P(≥1 starter in opening 5) ≈ 0.61 from hypergeometric (Inferred); Brick rate estimate ~25–30% due to 55-card main and ritual Normal Summon bottleneck (Inferred); Median combo output: single Nekroz boss + 1–2 hand traps, power index ~55 (no sample data) (Inferred); Resilience floor: one choke point on ritual spell; secondary redundancy low (Inferred); Going-first board: 1–2 negation effects, ~2300 ATK boss, interaction layer modest (Inferred); Going-second plan: hand-trap reliance; board-break capacity hampered by missing Forbidden removal (Inferred); Pilotability: ritual sequencing 3–4 steps; moderate error tolerance (Inferred)
• Provisional: Meta Power: null (no dated metagame sample; Nekroz archetype meta-share unavailable in tournament_context); Format fit: provisional 25 (deck is illegal; format fit unknown when corrected); Post-side performance: unknown (no side deck supplied)
• Data gaps: No combos supplied in combos_evidence; all power index claims are text-based inference No tournament link; archetype meta-share and per-pilot match record absent No win-rate telemetry in YGOVN; going-first/going-second rates, brick/starter rates, matchup records unknown No side deck provided (0 cards); post-side adaptation and tournament reliability unmeasurable No guides supplied for Nekroz in this deck export; strategic intent inferred from card composition only Legality violations block competitive evaluation; structural score is theoretical only
