Nekroz Deck #761224 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Ritual Summon high-Level Nekroz monsters (Brionac, Trishula, Valkyrus, Areadbhair, Decisive Armor) to establish 2800-3300 ATK boards; Fusion Summons of Extra Deck monsters (Filia Regis, Predaplant Triphyoverutum, Almarduke) using Super Polymerization and Nekroz Mirror/Cycle
• Turn 1 (going first): Search Nekroz Ritual Spell via Preparation of Rites or Divinemirror, then Ritual Summon a Nekroz monster; protect the starter with Ash Blossom and Infinite Impermanence where legal
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Infinite Impermanence) to disrupt the opponent's first board, then Ritual Summon through the remaining resources
• Recovery: Recurse Nekroz monsters from GY via Nekroz Mirror, Unicore, or Clausolas effects and rebuild a Ritual Summon
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck is Illegal in OCG: three cards exceed their banlist limits (Ash Blossom, Super Polymerization at 3 copies; Droll & Lock Bird at 2 copies), so this is a theoretical, structural-only read capped low. Structurally the Nekroz core is reliable to access (about 90% to open at least one of the 15 archetype cards in a 5-card hand, and about 99% to hit a searcher), and the Ritual pathway reaches high-ATK boards. Hand-trap density (8 cards, about 74% to hold one going second) and Nekroz recursion give the deck some interruption resilience. Brick risk, a 49% exact-name archetype purity with 22 generic and several off-archetype copies, and the absence of any Side Deck pull the score down. Popularity and archetype usage stats confirm the list is real, not that it is strong, and the score was not produced by averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo secondary treated as informational only. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-12); side deck absence (0). Final formula: Illegal cap: theoretical structural read only. Structural 61 (Midrange profile) and TournamentReliability 50 give 0.80*61+0.20*50 = 58.8; banlist exposure modifier -12 gives 46.8; capped to 30 because the deck is Illegal (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• Core Ritual engine is highly accessible (about 91% to open a core card)
• Searcher density is very high (about 99% to hit a searcher)
• Hand-trap and recursion redundancy supports going-second interaction
• High-ATK Ritual finishers provide closing power

Weaknesses

• Illegal in OCG: three copy-limit violations
• No Side Deck, so no post-side adaptation
• Low archetype purity (49%) with many generic and off-archetype cards
• No recorded combos; floor and ceiling are text-only inference

Critical choke points

• A single Ritual Spell (Nekroz Mirror, Kaleidoscope, Cycle, or Divinemirror) is needed to start most lines
• Ash Blossom and Droll are over-limit and must be cut to legal copies before the list is playable
• Going-second hands depend on hand traps; a hand with none gives no answer to the opening board

Recommended changes

Evidence & confidence

• Verified: Illegal status: three over-limit cards per banlist (Ash Blossom, Super Polymerization, Droll & Lock Bird); Main 42, Extra 15, Side 0 within OCG size rules; Archetype composition: 28 exact-name Nekroz, 22 generic, 29 off-archetype copies; Core inclusion: Brionac 80%, Avance 60%, Unicore 60%, Preparation of Rites 60%
• Inferred: P(≥1 core card in opening 5) ≈ 0.91 and P(≥1 hand trap in going-second 6) ≈ 0.74; Ritual chains reach 2800–3300 ATK finishers; Interaction density from negation and removal text
• Provisional: Meta Power and matchup fit: no dated metagame sample and no 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 for going-first/second, matchup, or brick/starter rates Meta Power provisional without a dated metagame sample Deck has no title, and the list is Illegal, so no normal Final Contextual score is given
