Nekroz Deck #773305 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon high-ATK Nekroz bosses (Nekroz of Sophia 3600, Areadbhair 3300, Valkyrus 2900, Trishula 2700) backed by negation effects; Generic Extra Deck threats (Myutant Ultimus, Absolute Axon Kicker, TY-PHON, Garura, Elder Entity N'tss) when Ritual lines are disrupted
• Turn 1 (going first): Open a Ritual Spell plus a Ritual Monster (about 29% in 5 cards, Inferred); search with Emilia, Avance, Shurit, Preparation of Rites, then Ritual Summon via Mirror, Cycle, Kaleidoscope or Divinemirror
• Turn 2 (going second): Six-card hand has about 41% chance of Ritual Spell plus Ritual Monster (Inferred); Effect Veiler as a hand trap to negate a sole opposing effect, then Ritual Summon a negation boss
• Recovery: Recur Ritual Spells from the GY with Preparation of Rites and banish-cost Nekroz Mirror/Divinemirror; Nekroz monsters that negate on-field effects rebuild the board
• After siding: No side deck is registered (0 cards); no post-side plan exists in the evidence

Why it scores here

The deck scores as a system: a 40-card Nekroz Ritual engine with 28 searcher-text cards, 11 Ritual Monsters and 4 Ritual Spells, plus a generic 15-card Extra Deck. Its reliability rests on search density and recursion rather than on any single card, and the score does not average the individual card powers. Ritual Spell access is the main weakness: the hypergeometric estimate for a Ritual Spell in the opening five is about 0.43 (Inferred), so the starter is not reliably live on the first turn. Interaction is the strongest area, with Effect Veiler, multiple negation-effect Ritual Monsters and Ultimate Slayer, and the top-end bosses give good closing power. Popularity did not earn points: the Nekroz usage stats confirm the list is real and accessible, but there are no recorded boards, tournament results or side cards to support a higher score.

Dimension scores

How the score was computed

Strategy profile: Midrange, D13 dropped and renormalised over 95 (meta-neutral). Structural ≈ 60, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Generic Extra Deck dilution (-2); No side deck (-1); Off-archetype main-deck splash (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural 60.0, TR 55, modifiers -3)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.43 · key two-card combo ≈ 0.29 · 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

• Dense searcher text (28 cards) and recursion through Preparation of Rites, Mirror, Cycle and Divinemirror
• Multiple negation-effect Ritual Monsters and Effect Veiler give layered interaction
• High-ATK Ritual bosses (3600/3300/2900) provide strong closing power

Weaknesses

• Only 4 Ritual Spells: the opening-hand Ritual Spell chance is about 43% (Inferred)
• Generic Extra Deck (13 distinct, mostly off-archetype) with 47% exact-name purity
• No side deck, so no post-side plan

Critical choke points

• Ritual Spell in hand on going-first (about 43%)
• Extra Deck monster needed as cost for Nadir Servant, Ultimate Slayer and Kaleidoscope

• Provisional: Meta Power (null); D13 matchup and format fit (excluded from Structural)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference (combos_evidence.total_combos = 0) No tournament link: archetype meta-share and match record are absent No win-rate telemetry: going-first, going-second, matchup and starter rates are Inferred Usage join error: Code Igniter, Toadally Awesome, Evilswarm Exciton Knight and Number 4: Stealth Kragen are listed as not in deck (in_this_deck=false, missing_core) but appear in the extra list with copies 1; core_cards_present (7/11) is undercounted and likely 11/11 Meta Power is Provisional: no dated metagame sample Side deck empty (0 cards): D12 has no performance data
