Legality

Main 59 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

  • Win condition: Fusion or Link boards (Chimera, Hecahands, Fiendsmith) that overwhelm a single-turn board with 2400 to 3500 ATK monsters; Chaos Angel and Guardian Chimera as high-ATK closers once the Main Deck engines have set up
  • Turn 1 (going first): Fiendsmith Engraver (only 1 legal copy) or Lacrima the Crimson Tears to reach Fiendsmith's Tract or Lacrima; the 3-copy Mulcharmy and Chimera starters add a second line if Fiendsmith is absent
  • Turn 2 (going second): Hand traps (Ash Blossom, Droll, Infinite Impermanence, Ghost Ogre) to slow the opponent, then Hecahands or Chimera Fusion summons to rebuild a board
  • Recovery: Hecahands and Mulcharmy draw and recursion effects plus Fabled Lurrie in the GY to refill the hand after a board wipe
  • After siding: Not evaluable: the deck runs no Side Deck (0 cards), so there is no post-side plan in the list

Why it scores here

The list is Illegal in OCG (three cards over their copy limits, two Forbidden cards, and a 16-card Extra Deck), so it is capped and scored as a theoretical, structural read only. Its engines are split across at least four sub-archetypes (Fiendsmith 8 exact copies, Hecahands 16, Mulcharmy 6, Chimera 5 with 10.7% exact-name purity), so starters often miss the engine they need. Interaction is dense (11 hand traps, 14 negation texts, Ash Blossom, Ib'al and Yad'al-Hecahands), and the Extra Deck carries high-ATK closers (Chaos Angel, Guardian Chimera, Hecahands Xeno). The score does not come from the popularity of the Fiendsmith archetype, the usage statistics, or an average of card scores; with no combos, guides, or dated meta, consistency is Inferred and Meta Power stays null.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 50 P(at least one Engraver in a 5-card hand) ≈ 0.24 at 3 copies, and only 1 copy is legal; the Fiendsmith engine needs Engraver or Lacrima (Inferred)
D2 Opening-Hand Quality & Brick Management 40 Three sub-archetype engines plus 3-copy Mulcharmy and Chimera starters give conflicting hands; P(core group in hand) ≈ 0.53 (Inferred)
D3 Combo Conversion & Ceiling 40 No parseable recorded boards; ceiling is inferred from Chimera, Hecahands and Fiendsmith text only (Inferred)
D4 Combo Floor & Median Output 35 No combo data, so floor and median are unknown and set from text only (Inferred)
D5 Interruption Resilience & Route Redundancy 50 Eleven hand traps and recursion (Lurrie, Mulcharmy, Hecahands) give some line redundancy, but the engines are disjoint (Inferred)
D6 Resource Economy, Recovery & Grind 50 Hecahands and Mulcharmy draw effects and GY recursion refill the hand; the Fiendsmith GY revival path is present (Inferred)
D7 End-Board & Interaction Quality 60 Negation and removal density is high (14 negation texts, 21 removal texts, Illusion Gate, Ib'al and Yad'al-Hecahands) (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 50 Hecahands and Chimera boards with Droll and hand traps challenge a board, though Droll is over its limit (Inferred)
D9 Offensive Pressure & Closing Power 60 Chaos Angel 3500, Guardian Chimera 3300, Hecahands Xeno 3400 and Chimera Illusion 3100 provide closing ATK (Verified stat, Inferred closing)
D10 Main Deck Efficiency & Flexibility 25 59 Main Deck cards across 30 distinct names with a 4-engine spread and 10.7% exact purity; efficiency is low (Verified composition, Inferred)
D11 Extra Deck Efficiency & Coverage 40 16 Extra cards (over the limit of 15) across 14 distinct cards, mixing Fusion, Link, Synchro and Xyz engines (Verified composition)
D12 Side Deck Adaptability 20 Zero Side Deck cards, so no adaptation is possible in the list (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament link or dated meta sample; matchup fit is Provisional
D14 Pilotability & Error Tolerance 30 Four interleaved engines and multiple hand-trap timing decisions put the error load high (Inferred)

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary not blended (weights used as-is). Structural ≈ 45, Going First ≈ 40, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-6); engine conflict (-4); extra_deck_overflow (-2). Final formula: Illegal cap: 0.80*Structural(45) + 0.20*TournamentReliability(30) = 42, then context modifiers -12 = 30 (Meta provisional, theoretical only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.24 · 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

  • Dense interaction: 11 hand traps and 14 negation texts
  • High closing ATK in the Extra Deck (Chaos Angel, Guardian Chimera, Hecahands Xeno)
  • Multiple recursion and search paths (Lurrie, Mulcharmy, Hecahands)

Weaknesses

  • Illegal list: three copy-limit overruns, two Forbidden cards, Extra Deck over limit
  • No Side Deck
  • Engines split across four sub-archetypes with low exact-name purity

Critical choke points

  • Fiendsmith engine depends on Engraver, which is legal at 1 copy only
  • Forbidden cards would be rejected at deck validation
Priority Remove Add Reason
1 2 Fiendsmith Engraver 0 (cap at 1 copy) Copy-limit violation; the list cannot be legally played as built
2 Called by the Grave and Triple Tactics Talent Legal tech or hand traps Forbidden in OCG
3 1 Droll & Lock Bird and 1 Ash Blossom & Joyous Spring Legal substitutes or nothing (cap at 1 Droll and 2 Ash) Copy-limit violations
4 1 Extra Deck card 0 Extra Deck is 16 cards against a 15 limit
5 Engine overlap (Mulcharmy or Chimera) A Side Deck of 8 to 15 cards Commit to one engine and add a Side Deck for adaptability

Evidence & confidence

  • Verified: Copy limits and banlist statuses (Forbidden: Called by the Grave, Triple Tactics Talent; Limited: Engraver, Droll, Lacrima, Tract; Semi-Limited: Ash Blossom); Main Deck 59 cards, Extra Deck 16 cards, Side Deck 0 cards; Card text excerpts for the 30 distinct Main Deck cards and 14 distinct Extra Deck cards
  • Observed: Archetype usage: Fiendsmith core cards Requiem, Sequence, Lacrima the Crimson Tears, Lurrie, Mulcharmy Fuwalos and Droll appear in high inclusion (usage statistics)
  • Inferred: P(at least one Engraver in 5 cards) ≈ 0.24 and P(archetype core group in 5 cards) ≈ 0.53; Interaction density is high from the hand-trap and negation text counts; Engine overlap lowers consistency and pilotability
  • Provisional: Matchup fit and Meta Power (no dated metagame sample); Side Deck adaptability (no Side Deck cards and no post-side data)
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no guides attached no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
