Labrynth Deck #759733 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 50 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Board control through hand traps and Normal Trap-driven Labrynth/Plunder Patroll boards, closing with Extra Deck boss monsters (Lady Labrynth 3000 ATK, Lovely Labrynth 2900 ATK, Chaos Angel 3500 ATK, Plunder Patrollship Brann 2500 ATK); Plunder Patroll Extra Deck pressure (Blackbeard, Lys, Moerk, Brann) once the field is established
• Turn 1 (going first): Open a Labrynth starter (Labrynth Cooclock, Lovely Labrynth, Big Welcome Labrynth, Welcome Labrynth) and hold a hand trap (Ash Blossom, Infinite Impermanence, Evenly Matched) for the first opponent summon
• Turn 2 (going second): Use the hand-trap density (13 hand-trap-tagged cards, about 85% chance of at least one in a 6-card opening hand) to break the opponent's first board, then rebuild through Labrynth Chandraglier and Labrynth Stovie Torbie recursion
• Recovery: Recover from GY through Labrynth Chandraglier, Labrynth Stovie Torbie, Labrynth Cooclock and Arianna the Labrynth Servant, and reuse Normal Traps through Lovely Labrynth
• After siding: Not applicable: Master Duel uses no side deck in this list (side 0), so no post-side plan can be scored

Why it scores here

This list is Illegal in master-duel: Maxx C is run three times against a limit of one, and Called by the Grave (Forbidden) is run twice, so the normal Final Contextual score does not apply and the 30 shown is a capped, structural-only read. The structure is a Control profile: the hand-trap package (Ash Blossom, Infinite Impermanence, Evenly Matched, Nibiru, Maxx C) gives the deck a high going-second interaction density, and the Labrynth Normal Trap engine with Chandraglier and Torbie recursion gives it a reasonable chance to rebuild after disruption. Points were earned by the system (interaction, recursion, and the Labrynth/Plunder Patroll Extra Deck boss pool), not by averaging card scores, and popularity is not credited: the usage stats only confirm the Labrynth core is standard. The weakest parts are the split between Labrynth and Plunder Patroll (exact-name purity 27.7% with 47 off-archetype copies, so engine coherence is poor), the absence of any recorded boards, and no side plan. Meta Power is provisional and no win-rate evidence exists.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*51 + 0.20*45 = 49.8; modifiers -12 gives 37.8; Illegal-status cap applied, final score = 30 (structural-only, not a normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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 hand-trap package (13 cards) gives strong going-second interaction
• Labrynth recursion (Chandraglier, Stovie Torbie, Cooclock, Arianna) supports rebuilding after disruption
• Several 2900-3500 ATK boss options from both Labrynth and Plunder Patroll Extra Deck routes

Weaknesses

• Illegal list: Maxx C over limit (3 vs 1) and Called by the Grave (Forbidden) run twice
• Two engines compete: 47 of 50 main copies are off the exact Labrynth name, and Plunder Patroll Extra Deck pieces need their own resources
• No recorded boards or win-rate telemetry, so the combo ceiling and floor cannot be measured
• Master Duel side deck is empty, so no post-side adaptation exists

Critical choke points

• Normal Trap timing: many Labrynth and Plunder Patroll effects require a Normal Trap in hand or on the field, and Welcome Labrynth is run only once
• Called by the Grave is Forbidden in master-duel, so its inclusion is an immediate legality failure and a removal-line dependency

Recommended changes

Evidence & confidence

• Verified: Legality: Called by the Grave (Forbidden, 2 copies), Maxx C (Limited, 3 copies vs legal 1), status Illegal; Main 50 / Extra 15 / Side 0 within master-duel size rules; Card texts for hand-trap, searcher and recursion roles; Usage statistics: Labrynth core cards present at 84-93% inclusion
• Inferred: Hypergeometric consistency: archetype core at least one in 5 about 0.93; hand-trap at least one in 6 going second about 0.85; Control profile weighting; structural score 51; Interaction breadth and recursion read from text roles; Engine conflict between Labrynth and Plunder Patroll
• Provisional: Meta Power (no dated metagame sample); Tournament reliability and format fit (no tournament link); Side deck adaptability (Master Duel side is empty)
• 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 (going-first/second, matchup, brick and starter rates) Meta Power provisional without a dated metagame sample Deck title is null, so the deck is identified only by archetype and deck id
