Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: Fusion Summon Darklord and Gem-Knight Fusion Monsters (Eveningstar, The First Darklord, Lady Rose Diamond) for board pressure; Recursion-driven grind through Darklord Contact, Morningstar, Gulgolet and Nepyrim in the GY
  • Turn 1 (going first): Search via Banishment of the Darklords or Indulged Darklord, open Djehuty or Gulgolet for a Darklord summon, then fuse toward a 3000+ ATK Fusion Monster
  • Turn 2 (going second): Hold Herald of Orange Light and Herald of Green Light as hand-trap negates, then rebuild through Darklord Contact and Gem-Knight searchers
  • Recovery: Use Darklord Contact and Morningstar recursion to return Darklord monsters from the GY
  • After siding: Not applicable: Master Duel has no side deck and the list runs 0 side cards

Why it scores here

The list is Illegal as submitted: it runs 3 copies of Herald of Orange Light against a Limited cap of 1, so it receives a structural-only read and its score is capped at 30 rather than a normal Final Contextual score. Scored as a system, its strength is access and recursion: 22 searcher-text cards give a 0.987 chance of at least one searcher in the opening 5, and Darklord Contact, Morningstar and Gulgolet return Darklord monsters from the GY. Interaction is layered through three Herald/Buio negates plus Sanctified Darklord, Darklord Rebellion and Forbidden Droplet. The weaknesses are a split identity (Darklord core labelled Herald, with only 10.9% exact-name purity) and a 15-card Extra Deck that is entirely Fusion with several generic members and no recorded boards to confirm conversion. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one of 3 copies in opening 5) = 0.338 per starter; 22 searcher-text cards give P(>=1) = 0.987 (Inferred)
D2 Opening-Hand Quality & Brick Management 55 8 singleton slots and 3-copy starters give a moderate brick risk; no brick estimate is computable from the list alone (Inferred)
D3 Combo Conversion & Ceiling 58 No recorded boards; ceiling read from text only, e.g. Eveningstar and The First Darklord reach 3000 and 4000 ATK (Inferred)
D4 Combo Floor & Median Output 45 No combos evidence, so the median is text-only and sits low given split Darklord/Gem-Knight/Herald plans (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Redundant starters across Darklord, Herald and Gem-Knight lines plus GY recursion give multiple independent routes (Inferred)
D6 Resource Economy, Recovery & Grind 60 Recursion via Darklord Contact, Morningstar, Gulgolet and Nepyrim gives grind value (Inferred from text)
D7 End-Board & Interaction Quality 62 Three Herald/Buio negates plus Sanctified Darklord, Rebellion and Droplet give broad quick-effect interaction (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 55 Going-second hand-trap coverage: P(>=1 of 3 hand traps in 6-card hand) = 0.394 (Inferred)
D9 Offensive Pressure & Closing Power 60 Eveningstar at 3000 ATK and The First Darklord at 4000 ATK are strong closers if summoned (Verified stat, Inferred use)
D10 Main Deck Efficiency & Flexibility 48 40 main cards with 20 distinct; 6 exact-Herald copies against a Darklord core of 26 copies lowers coherence (Verified composition)
D11 Extra Deck Efficiency & Coverage 52 15 Fusion Extra with 3 copies each of the two Darklord fusions; several generic and Gem-Knight members are situational (Verified composition, Inferred)
D12 Side Deck Adaptability 30 No side deck exists in Master Duel (0 side cards), so no post-side plan is available (Verified)
D13 Matchup Coverage & Format Fit 45 No dated meta sample or tournament link; format fit cannot be established (Provisional)
D14 Pilotability & Error Tolerance 35 Fusion requirements, multi-step GY recursion and several OPT chains raise decision load (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 56, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-8); engine conflict (-3). Final formula: Illegal: uncapped 0.80*55 + 0.20*42 + (-11) = 41; capped to 30 as structural-only per the legality rule (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.34 · 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

  • Searcher density (22 cards) gives near-certain access to a search every opening hand
  • Layered negate and removal interaction (Herald/Buio hand traps, Sanctified Darklord, Darklord Rebellion)
  • GY recursion (Contact, Morningstar, Gulgolet) supports grinding after disruption
  • High-ATK Fusion closers (Eveningstar, The First Darklord)

Weaknesses

  • Illegal as submitted: 3 copies of Herald of Orange Light against a limit of 1
  • Split identity: Darklord core labelled Herald with 10.9% exact-name purity
  • Extra Deck is 15 Fusions with several generic members and no recorded conversion data
  • No side deck, so no post-side adaptation

Critical choke points

  • Herald of Orange Light must drop to 1 copy to be playable at all
  • Fusion summons depend on specific Darklord and Gem-Knight materials being in hand or GY
Priority Remove Add Reason
1 2 copies of Herald of Orange Light 2 copies of Darklord Contact (Unlimited, legal at 3) Brings the list into legal copy limits and adds GY recursion that matches the Darklord core
2 1 Gem-Knight Hollowcore (or one generic Extra Deck Fusion) A second Darklord searcher or the Darklord Ixchel slot already in the pool Tightens the Darklord identity to reduce archetype split and improve starter density

Evidence & confidence

  • Verified: Illegal copy-limit violation: Herald of Orange Light 3 copies vs Limited 1; Main 40, Extra 15, Side 0 are within MasterDuel size rules; Card texts and banlist statuses from the evidence pack; Archetype purity 10.9% exact-name; Darklord 26 copies
  • Inferred: Starter access 0.338 per 3-copy starter and 0.987 searcher access (hypergeometric); Interaction density and negate coverage from card text; Recursion-based grind estimates
  • Provisional: Meta Power and format fit (no dated metagame sample)
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for this deck Meta Power provisional unless a dated metagame sample is supplied Deck title is null, so identity rests on the archetype label and card composition
