Nekroz Deck #770085 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon a high-ATK Nekroz boss (Ruler of the End of the World, Nekroz of Areadbhair, Nekroz of Valkyrus, Nekroz of Trishula) from the Ritual engine, then close with Extra Deck Link/Xyz/Fusion follow-ups; Super Starslayer TY-PHON - Sky Crisis and Number 39: Utopia as Extra Deck closers once the board is established
• Turn 1 (going first): Open with a Nekroz Ritual Spell (Divinemirror, Mirror, Kaleidoscope or Cycle) plus a Ritual Monster or a searcher (Preparation of Rites, Emilia, Avance) to reach a Ritual Summon by turn 2, keeping a Ghost Belle or Ash Blossom up for the opponent's first activation
• Turn 2 (going second): Use the hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle) to answer the opponent's opening, then rebuild through Nekroz GY recursion (Unicore, Clausolas, Shurit) and Ritual Summon the boss
• Recovery: Recover through Nekroz GY-based recursion and Ritual Spells that return from the GY (Nekroz Mirror, Nekroz Cycle, Readying of Rites), and Extra Deck Links that reuse materials after an interruption
• After siding: No side deck is registered (side_count 0), so there is no evidenced post-side plan; any post-side adjustment is outside this deck's evidence

Why it scores here

The score comes from the system: the Nekroz Ritual engine is redundant (13 archetype-core copies give about 0.88 chance of at least one core card in a 5-card opening hand, and 23 searcher-text cards give about 0.99 chance of at least one searcher), so the deck reliably reaches a live engine on turns 1 to 2. Its interaction density is high, with six hand traps (about 0.65 chance of one in a 6-card going-second hand) and several Nekroz monsters that negate or remove, which keeps the engine alive through disruption and lets it recover through GY-based recursion. Its closing power comes from 3000 to 3300 ATK Ritual bosses and Extra Deck Link/Xyz follow-ups. The score is held back by the absence of any side deck (no post-side plan), by no recorded boards to measure real combo output, and by the Ritual-heavy sequencing that makes the deck demanding to pilot. Popularity was not credited: the archetype usage stats confirm the list is real, but they do not raise the score, and no card scores were averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary (~80/20 by profile). Structural ≈ 67, Going First ≈ 70, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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 Ritual engine with 23 searcher-text cards and about 0.88 core-card access in the opening 5
• Six hand traps and nine negation-text cards give layered interaction for going first and second
• Strong boss ATK (2900 to 3300) plus Extra Deck Link/Xyz/Fusion follow-ups
• Legal list: all restricted cards are within their copy limits (S:P Little Knight 1/1, Ash Blossom 2/2, Super Polymerization 2/2)

Weaknesses

• No side deck: no post-side plan in a best-of-3 setting
• Ritual-heavy sequencing with a low exact-name archetype purity of 40% and 33 off-archetype copies
• No recorded combo boards, so the floor and median are inferred from text only
• Extra Deck of 15 with several cards that need specific materials (Mereologic Aggregator needs Level 9 materials)

Critical choke points

• Ritual Monster and Ritual Spell must both be in hand or GY to start the engine; a hand with only one of the two is a brick
• Hand-trap coverage depends on opponent's activation timing; a going-second hand with no hand trap is common (about 0.35 chance)
• Boss revival depends on a GY Nekroz card for recursion lines

Recommended changes

Evidence & confidence

• Verified: Legal under the OCG BanList with 40 Main, 15 Extra and 0 Side cards; Semi-Limited copies within limits: Ash Blossom 2, Super Polymerization 2; Limited S:P Little Knight 1; Archetype core stat: Nekroz of Brionac at 80% inclusion, 3 copies run
• Inferred: At least one archetype-core card in the opening 5 is about 0.88 (hypergeometric); At least one searcher in the opening 5 is about 0.99 (hypergeometric); Going-second hand trap probability is about 0.65 (hypergeometric); Hand-trap interaction and Ritual boss closing power read from card text
• Provisional: Meta power is null: no dated metagame sample supplied; Matchup fit (D13) is a neutral placeholder: no archetype meta-share or tournament link; Post-side plan (D12) cannot be evaluated: no side deck
• 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/second, matchup, brick/starter rates): those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Usage-stat inconsistency: usage_statistics marks Toadally Awesome (90809975) and Number 4: Stealth Kragen (67557908) as not in the deck, but both appear in the cards list (zone extra, 1 copy each); core_present_pct of 63.6% may undercount the archetype core Side deck is empty (side_count 0): no post-side evidence at all
