Nekroz Deck #772600 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual Summon high-ATK Nekroz monsters (Brionac, Trishula, Areadbhair, Decisive Armor, Valkyrus) through the Nekroz Ritual Spell engine, then attack or negate to close; Fusion Summon from the Extra Deck, but only one Fusion enabler (Super Polymerization) is in the Main Deck and it is over the copy limit
• Turn 1 (going first): Search a Ritual Spell (Preparation of Rites, Nekroz Mirror, Cycle, Kaleidoscope) or a Ritual Monster, then Ritual Summon Brionac or Trishula through Divinemirror/Cycle (Inferred from card text)
• Turn 2 (going second): Same Ritual engine through a six-card hand, plus Trishula/Unicore/Clausolas negation effects to answer the opponent's board (Inferred from card text)
• Recovery: Recycle Nekroz monsters from the GY via Unicore and Clausolas effects to add them back to hand; Shurit and Emilia searches restock the engine (Inferred from card text)
• After siding: Not evaluable: the list has 0 Side Deck cards, so there is no post-side plan

Why it scores here

The Nekroz engine is consistent on paper: 15 Nekroz-core copies give a 90.5% chance of at least one in a five-card opening hand, and 30 searcher-text cards make a starter nearly certain to be reachable by turn 2 (Inferred). The Ritual Spell suite plus Brionac, Trishula and Areadbhair gives a high ceiling and strong closing bodies at 2300 to 3300 ATK, and the Trishula, Unicore, Clausolas and Valkyrus effects supply real negation. The list cannot be scored normally because it is illegal: Super Polymerization runs 3 copies against a limit of 2, so this read is theoretical and structural only and is capped at 30. The Extra Deck is the main structural weakness, with 15 Fusion Monsters but only one Fusion enabler in the Main Deck, so most of the Extra Deck is dead. The score comes from the system (consistency, ceiling, negation density, and the Extra Deck gap), not from averaging card scores or from the archetype's usage or popularity.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 52, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Illegal copy-limit cap (-23). Final formula: Illegal deck: theoretical structural read (Combo profile = 53) capped at 30; the normal 0.80*Structural + 0.20*TournamentReliability formula is not applied (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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 engine with 8 Nekroz Ritual Spells and 13 Ritual Monsters
• Very high searcher density (30 searcher-text cards), so starter access is strong
• Negation and removal text across 8 and 14 cards, with 3 tech cards
• Closing bodies at 2900 to 3300 ATK

Weaknesses

• Illegal: Super Polymerization over the copy limit (3 vs 2)
• 15 Fusion Monsters with only one Fusion enabler, so most of the Extra Deck is dead
• Only 28 of 57 Main and Extra copies are exact Nekroz; 29 are off-archetype or generic
• No Side Deck (0 of 15 slots used)

Critical choke points

• Single Super Polymerization line for the entire Fusion Extra Deck (and it is illegal at 3 copies)
• Ritual Spell requirement: Brionac and Trishula need a Nekroz Ritual Spell in hand or GY

Recommended changes

Evidence & confidence

• Verified: Legality: Super Polymerization 3 copies vs limit 2 (Illegal); Main 42, Extra 15, Side 0 counts within OCG size rules; Archetype purity 49.1% (28 of 57 exact Nekroz copies); Hypergeometric draw probabilities from the Main Deck list; Usage stats: 7 of 11 core cards present (63.6%)
• Inferred: Starter access from searcher density and the 15-copy core group; Brick and dead-Extra-Deck risk from single-enabler Fusion slots; Ritual ceiling and negation value from card text; Going-first and going-second strength estimates
• Provisional: Meta Power (no dated metagame sample); Format fit and matchup coverage (no tournament link)
• Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first/second, matchup, brick, or starter rates) No guides attached to the archetype No Side Deck, so post-side performance cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
