Labrynth Deck #770359 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Combo, Stun
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Extra-Deck Fusion/Synchro boss (Titaniklad, Mirrorjade, Crimson King, Red Dragon Archfiend, Psychic End Punisher) reached through Fallen-of-Albaz material lines and Labrynth/Dogmatika search; Hand-trap and Normal Trap interaction that stops the opponent's engine so the Extra-Deck boss lands unopposed
• Turn 1 (going first): Open a Labrynth/Dogmatika starter (Arianna, Big Welcome, Dogmatika Ecclesia) or a Fallen-of-Albaz body, search or summon toward a Fusion/Synchro boss, and hold a hand trap (Ash, Impermanence, Droll, Maxx C) for the first opposing play
• Turn 2 (going second): Use the 9 hand traps (about 0.81 chance of at least one in a six-card hand) to negate the opponent's first summon or search, then convert the surviving board into a boss
• Recovery: Recover through GY-based effects (Fallen & The Virtuous, Droll, Ecclesia and Dark Dragon from GY, Rindbrumm from GY) and Normal Trap recursion (Lovely Labrynth, Big Welcome)
• After siding: Not applicable to Master Duel ranked play (side = 0); adjustment is limited to the Extra-Deck choice and the 40-card main

Why it scores here

The deck opens a live starter often enough but not reliably: a Fallen-of-Albaz body (three effective copies counting Fallen of the White Dragon) has about a 0.34 chance of appearing in a five-card opening hand, and the Labrynth starters (Arianna x2, Big Welcome x2) are about 0.24 each, so the engine is accessible but built on several separate routes rather than one unified line. Interaction is the strongest part of the system: 9 hand traps, 14 traps overall and about 11 negation and 16 removal text hits, which makes it hard for the opponent to build a board on either turn order. Its ceiling comes from a 15-card Extra Deck of boss monsters (Titaniklad, Mirrorjade, Crimson King, Red Dragon Archfiend, Psychic End Punisher), but the Extra summons are gated by Fallen-of-Albaz material, so the median is much lower than the ceiling. The score reflects the deck as a system: consistency, median output, and interaction layering, with a penalty for fragmented sub-archetypes (only 7 of 55 archetype-tagged copies are exact 'Labrynth' names). Popularity did not earn points: the archetype is confirmed as real by usage data, but usage was not treated as strength, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 60, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Fallen-of-Albaz choke point (-3); Engine fragmentation (-4); Layered interaction (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural = weighted Midrange profile with D13 dropped and renormalized over 95

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

• Nine hand traps and layered Dominus/Normal-trap interaction give strong answers on both turns
• Extra Deck of high-ATK bosses (2500-3500) gives real closing power once the Fallen material line resolves
• Usage data confirms the core is real: Maxx C, Dominus Spark/Impulse, Infinite Impermanence, Lovely Labrynth are archetype-standard

Weaknesses

• Starter access depends on about three Fallen-of-Albaz bodies (about 0.34 in a 5-card hand), with no second starter route of similar reliability
• Fragmented engine: 7 exact Labrynth copies, with the rest spread across sub-archetypes that do not share an engine
• Deviates from the archetype's standard core (Songs of the Dominators 1 vs typical 3, Dominus Spark 2 vs typical 3, Big Welcome 2 vs typical 3, Ariane and Labrynth Cooclock absent)
• No side deck and no combo evidence, so the post-side and combo-ceiling claims are inferred

Critical choke points

• Fallen of Albaz (1 copy) plus the two Fallen of the White Dragon copies that are treated as Fallen of Albaz: losing these bodies stalls most Fusion boss lines
• Normal Trap dependence for the Labrynth and Dominus traps (Lovely Labrynth, Big Welcome, Dominus Impulse/Spark)

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side within size rules; all Limited/Semi-Limited copy counts within limit; Main Deck composition and copy histogram (12 singletons, 8 twos, 4 threes; 8 Fusion + 7 Synchro in Extra); Usage stats: Maxx C, Dominus Spark, Dominus Impulse, Big Welcome, Infinite Impermanence, Lovely Labrynth at 100% or 67% archetype inclusion; 10 of 23 core cards present
• Observed: No recorded boards: combos_evidence has 0 parseable boards, so no measured floor, median, or ceiling
• Inferred: Starter access: about 0.34 for the Fallen-of-Albaz bodies, 0.24 for Arianna, 0.74 for searcher text in a five-card opening hand; Going-second hand-trap access about 0.81 in a six-card hand; Interaction layering from card text (14 traps, 11 negation, 16 removal); Closing power from Extra-Deck ATK values and text
• Provisional: Meta Power (null): no dated metagame sample; Matchup and format fit (D13): no tournament link, dropped from the structural score
• Data gaps: no combos supplied (combos_evidence.total_combos = 0): combo floor, median, and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry for going-first/second, matchup, or brick rate no dated metagame sample: Meta Power stays null Master Duel side deck is 0: post-side adaptability cannot be measured
