Labrynth Deck #765912 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Toolbox
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Labrynth Normal Trap engine converting Normal Trap activations into Special Summons and recursion, closed by Xyz/Fusion boss monsters (Arc Rebellion Xyz Dragon, Lady Labrynth of the Silver Castle, Lovely Labrynth of the Silver Castle); Trap-based negation and removal (Dominus Impulse, Songs of the Dominators, Infinite Impermanence, Maxx "C") grinding the opponent's board until a boss monster lands
• Turn 1 (going first): Open with a Labrynth/Lilith monster plus a Normal Trap to trigger the engine, and hold hand traps (Maxx "C", Infinite Impermanence) for the opponent's first Special Summon or effect
• Turn 2 (going second): Hand-trap and negate the opponent's opening Special Summons with Maxx "C", Dominus Impulse and Songs of the Dominators, then convert the surviving Normal Trap recursion into a boss Extra Deck monster
• Recovery: Recover Normal Traps from the GY (Big Welcome Labrynth, Welcome Labrynth, Trap Holic) and re-deploy Labrynth monsters from the GY; Xyz/Fusion extra-deck monsters replace boards that were cleared
• After siding: No side deck is registered (side_count 0), so there is no evidenced post-side plan; this is a gap, not a strength

Why it scores here

The deck reliably opens a functional hand: with 9 monsters among 40 main cards, the hypergeometric estimate of at least one monster in the opening five is about 0.74, and the Labrynth engine needs both a monster and a Normal Trap, which 31 trap-type cards supply often enough. Its strongest value is interaction density, with four hand-trap or negation-text cards (Maxx "C", Infinite Impermanence, Dominus Impulse, Songs of the Dominators) and removal-text cards that cover both turns, which is why end-board interaction scores highest. Conversion is capped by the thin monster count and the lack of recorded boards: with no combo evidence, the conversion and median scores are text-based inference only. The deck does not earn points from archetype popularity (the core group is present in 72% of the archetype's usage rows) and no score was obtained by averaging card scores. The side deck is empty, so the post-side and matchup dimensions remain low and provisional.

Dimension scores

How the score was computed

Strategy profile: Control profile; Toolbox used as descriptive secondary only, no blend applied. Structural ≈ 56, Going First ≈ 54, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: no side deck / weak post-side plan (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*56.3 + 0.20*50 = 55.0, minus 3 side-deck modifier = 52

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · key two-card combo ≈ — · full-brick estimate ≈ 0.26 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Four hand-trap or negation cards cover both turns and give the deck strong end-board interaction
• Labrynth Normal Trap recursion regenerates resources from the GY
• Legal list with copy limits respected (Maxx "C" and Tearlaments Kitkallos at 1 copy each, both Limited)
• Flexible Extra Deck (6 Fusion, 9 Xyz) with multiple boss options

Weaknesses

• Only 9 monsters in 40 main cards, so the engine is thin and bricks are plausible
• No side deck, so no post-side adaptation
• No recorded boards, so conversion and median output cannot be verified
• Generic trap-heavy structure: 27 generic off-archetype copies lower engine coherence

Critical choke points

• Lilith, Lady of Lament (3 copies) and the Labrynth monster line are the only monster supply; without a monster the Normal Trap engine stalls
• Opening-hand monster presence (~0.74) is the main consistency driver

Recommended changes

Evidence & confidence

• Verified: Legal status, 40 main / 15 extra / 0 side, Limited copies (Maxx "C", Tearlaments Kitkallos) within limit; Archetype usage rows: 22 total, 13 of 18 core cards present; Card stats for all resolved monsters
• Observed: Usage statistics show the archetype core is present in 72% of rows
• Inferred: P(>=1 monster in opening 5) ≈ 0.74 and P(0 monsters) ≈ 0.26; Engine recursion and interaction value from card text excerpts; Control-profile structural score of 56
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13 = 50)
• 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 side deck: post-side plan and D12 are unevidenced no win-rate telemetry for going-first/second, matchup, or brick/starter rates Meta Power provisional without a dated metagame sample
