Labrynth Deck #759398 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±7 · Confidence: Medium)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Labrynth Lady / Lovely Labrynth and link or synchro bodies (3000 ATK class) on a board built from Normal Trap activations; Psychic End Punisher, Unchained Abomination and A Bao A Qu as late-game closers, where the Extra Deck allows them
• Turn 1 (going first): Open a Labrynth starter or searcher (Arianna / Ariane / Cooclock) and chain Normal Traps to Special Summon or Set the next Labrynth monster, then hold Dominus Impulse or Trap Holic for the opponent's response
• Turn 2 (going second): Use hand-trap or negation Normal Traps (Dominus Impulse, Songs of the Dominators, Dimensional Barrier) to stop the opponent's first board, then rebuild through Labrynth recursion (Stovie, Chandraglier, Big Welcome)
• Recovery: Recur Normal Traps from the GY via Trap Holic and Labrynth GY effects (Chandraglier, Stovie, Lady) to rebuild the Labrynth board
• After siding: No side deck registered (side_count 0); no post-side plan is evidenced

Why it scores here

The deck's score comes from how the system behaves, not from averaging card strengths. Its 24 Normal Traps, out of 42 main-deck cards, let it set and chain a Labrynth engine and recur resources from the Graveyard, which supports the resource (D6) and interaction (D7) scores. Consistency is middling: the probability that a 5-card opening hand contains at least one of the 3-copy starter Arianna is about 0.32, and the probability of a full all-trap hand is about 5% going first and about 2.6% going second, so brick risk is real but modest. No recorded boards exist in the evidence, so the combo ceiling and median are text-only inferences and are scored conservatively. The deck's bodies (3000 ATK Lady Labrynth, Unchained Abomination, Psychic End Punisher) lift the closing score, but popularity and archetype usage were not counted as power. The missing side deck and the absence of any meta or matchup data hold the total near the middle of the scale.

Dimension scores

How the score was computed

Strategy profile: 70% Midrange / 30% Control. Structural ≈ 60, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Normal Trap access dependence (-2); Engine compactness (1); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers(-2) (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 24 Normal Traps give a dense engine that recurs resources from the GY
• Layered interaction: negations, destruction and banish across Dominus and Labrynth traps
• Link and synchro bodies at 3000 ATK-class close games
• Large Labrynth core (31 copies) gives high starter presence

Weaknesses

• 57% trap density raises the risk of monster-light hands
• No side deck and no recorded combos to verify the ceiling
• Chain-timing complexity lowers pilotability
• Usage statistics flag Chaos Angel, Muckraker and Super Starslayer as absent, which conflicts with the card list

Critical choke points

• A Normal Trap in hand is needed for most engine lines
• Maxx C is the only hand trap and is a single Limited copy

Recommended changes

Evidence & confidence

• Verified: Legality: 42 main, 15 extra, 0 side, all cards Unlimited except Maxx C (Limited, 1 copy); 24 Main Deck cards are Normal Traps (race Normal); Extra Deck composition: 9 link, 5 synchro, 1 xyz; Usage: Labrynth Cooclock, Maxx C and Lovely Labrynth at 84.6% inclusion
• Inferred: Hypergeometric starter and brick estimates; Interaction density from card text; Recursion and resilience from card text; Going-second board-breaking from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data); Post-side adaptability (no side deck)
• Data gaps: no combos supplied: 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 exists for this deck no side deck registered, so post-side is unevaluated usage_statistics marks Chaos Angel, Muckraker and Super Starslayer as not in deck, but the cards list includes them (Chaos Angel, Muckraker and Super Starslayer all zone extra, copies 1), so the usage in_this_deck flags conflict with the card list Meta Power is Provisional unless a dated metagame sample is supplied
