Identity & game plan

  • Win condition: Grind opponent via layered Normal Trap disruption and protected Labrynth boss monsters; Extra-deck synchro/link removal for cleanup and tempo
  • Turn 1 (going first): Set multiple Normal Traps via Arianna/Arias/Chandraglier, establish Lady Labrynth protected, negate with Dominus/Songs
  • Turn 2 (going second): Use Dimensional Barrier/Dogmatika Punishment/Eradicator Virus to break board, then summon synchro/link removal
  • Recovery: Recur traps with Transaction Rollback/Trap Holic/Lovely, GY monsters revive via Stovie/Chandraglier
  • After siding: No side deck (side_count 0) – relies solely on main deck consistency

Why it scores here

This Labrynth list is a trap-centric Control system that almost always opens a live starter (P(core live) ≈ 0.9996 inferred) and converts it into layered Normal Trap disruption backed by Lady Labrynth's protection. Median output is a resilient board of 1–2 negates plus removal, with redundant routes via GY recursion and Transaction Rollback, though its extra-deck synchro lines add ceiling at the cost of occasional garnet. Going-second power is modest and the complete absence of a side deck caps best-of-3 adaptability. The score reflects consistency, interaction quality, and grind on the connected system — not Labrynth's archetype popularity nor an average of individual card scores.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 82 Hypergeometric P(opening ≥1 core card) ≈ 0.9996 from 30 core copies; multiple 3-copy starters (Inferred)
D2 Opening-Hand Quality & Brick Management 75 22 traps but Labrynth monsters set/activate them from hand, estimated low brick rate except Fydraulis (Inferred)
D3 Combo Conversion & Ceiling 68 Ceiling board includes Lady Labrynth + Dominus/Songs negates + extra-deck removal, but no recorded combos (Inferred)
D4 Combo Floor & Median Output 65 Median expected: 1–2 trap disruptions and a 3000-ATK boss from typical opening (Inferred)
D5 Interruption Resilience & Route Redundancy 78 Redundant routes via GY revival (Stovie/Chandraglier) and Trap recycling (Transaction Rollback) (Inferred)
D6 Resource Economy, Recovery & Grind 80 Trap-heavy grind with Lovely/Trap Holic recur, resource signature favors long game (Inferred)
D7 End-Board & Interaction Quality 82 Interaction density high: 8 negation-text cards, 19 removal-text cards, Lady protection (Inferred)
D8 Going-Second & Board-Breaking Power 55 Going-second relies on Dimensional Barrier/Dogmatika/Eradicator but limited force-interaction (Inferred)
D9 Offensive Pressure & Closing Power 50 Bosses Lady 3000, Lovely 2900, extra synchros 3500 but slow offensive conversion (Inferred)
D10 Main Deck Efficiency & Flexibility 80 40-card compact main, 7 three-copy cores, minimal dead slots (Inferred)
D11 Extra Deck Efficiency & Coverage 65 15 extra cards span synchro/link/xyz/fusion but some generic pieces may be situational (Inferred)
D12 Side Deck Adaptability 10 Side deck count 0, no post-side adaptation plan (Verified)
D13 Matchup Coverage & Format Fit 55 Archetype usage stats confirm real list but no dated metagame sample for fit (Provisional)
D14 Pilotability & Error Tolerance 70 Trap timing decisions moderate; not high-complexity combo, error tolerance fair (Inferred)

How the score was computed

Strategy profile: Control. Structural ≈ 70, Going First ≈ 78, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 65. Modifiers: hard_garnet (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • High consistency of trap/monster core
  • Strong layered negation and removal via Normal Traps
  • Good recursion and grind through GY traps

Weaknesses

  • No side deck (side_count 0)
  • Going-second plan weaker
  • Extra deck may contain situational garnet (Fydraulis)

Critical choke points

  • Lack of side deck in best-of-3
  • Dependency on setting traps which can be countered by spell/trap removal
Priority Remove Add Reason
1 Fydraulis Harmonia Welcome Labrynth Welcome Labrynth is a core trap (81.8% inclusion) that improves recursion; Fydraulis is often a garnet

Evidence & confidence

  • Verified: Legality status Legal; Side count 0; Maxx C semi-limited copy 1
  • Observed: No parsed combos in evidence
  • Inferred: Consistency probabilities from hypergeometric; Interaction density from card text roles
  • Provisional: Matchup format fit without dated metagame
  • 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 win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
