Labrynth Deck #772697 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±9 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Control
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Labrynth boss monsters (Lady Labrynth of the Silver Castle 3000 ATK, Lovely Labrynth 2900 ATK) and Extra Deck beaters (Enigmaster Packbit 2900, Divine Arsenal AA-ZEUS 3000) after the opponent's interaction has been spent.; Going-second hand-trap and trap disruption that strips the opponent's board, then a Synchro or Xyz follow-up from the Extra Deck.
• Turn 1 (going first): Open with a Labrynth starter (Arias the Labrynth Butler, Big Welcome Labrynth) and set Normal Traps to protect the board, then convert with a Synchro or Xyz summon. Hold hand traps for the opponent's first activation.
• Turn 2 (going second): Use the 6-card hand to hold 1 to 2 hand traps (Infinite Impermanence, Ash Blossom, Ghost Ogre, Maxx C) against the opponent's first board, then rebuild with Labrynth recursion from the GY.
• Recovery: Recover from disruption by recycling Arias and Big Welcome from the GY, drawing with Glitter of Raise Moon or Maxx C, and using Pot of Extravagance to refill from the Extra Deck.
• After siding: Not defined: the deck has no Side Deck in the export, so there is no post-side plan. Best-of-3 play is unsupported by the current list.

Why it scores here

The deck reliably opens its Labrynth core: 10 core copies give about a 78% chance of at least one in an opening 5-card hand (hypergeometric, Inferred), and Big Welcome can summon from hand, Deck, or GY. Its strongest point is interaction on the system level: 8 hand traps, 21 traps, and Dominus Impulse, Mind Mirror Force, Dimensional Barrier, and Destructive Daruma give layered answers, and Lady and Lovely Labrynth protect the Normal Trap activations. The going-second hand-trap density (about 76% for at least one in 6 cards, Inferred) earns credit. Conversion and median output score lower because there are no recorded boards, and the 21 traps are dead without a Labrynth or hand-trap trigger. The deck runs no side deck, so post-side adaptability and best-of-3 resilience are weak. Points were earned from the system's consistency, interaction, and recursion, not from Labrynth's popularity or from averaging the card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Control secondary (not computed as a numeric blend; Midrange weights used for Structural). Structural ≈ 58, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: No side deck / weak post-side plan (-3); Engine conflict / split sub-archetypes (-2); Going-second hand-trap density (2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*57.9 + 0.20*55 = 57.4, then -4 modifiers = 53

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Labrynth core (Arias, Big Welcome, Lovely, Lady) is 78% likely in an opening 5 by the core proxy
• 8 hand traps and 9 negation-text cards give layered interaction, strong going second
• Big Welcome and Arias recursion from the GY supports recovery after disruption
• 15 Extra Deck slots with 3000-ATK bosses and a mix of Synchro, Xyz and Link

Weaknesses

• No side deck, so there is no post-side adaptation in best-of-3
• Exact archetype purity 16.4%: a toolbox of Dominus, Raise Moon, Ignister, From the Underworld and Greed dilutes the engine
• 21 traps and 17 monsters give a reactive, brick-prone opening hand
• No recorded boards, so ceiling and median are text-only and unverified

Critical choke points

• The Labrynth starter density is 10 core copies; a missing starter leaves the Normal Trap plan without its enablers
• Limited and Semi-Limited restrictions (Maxx C, Dimensional Barrier, Gozen Match, Ash Blossom, Dominus Impulse, Pot of Extravagance) each run at the legal maximum

Recommended changes

Evidence & confidence

• Verified: Legal OCG 40 Main / 15 Extra / 0 Side; no size or copy violations; Restricted cards: Dimensional Barrier, Gozen Match, Maxx C (Limited 1); Ash Blossom, Dominus Impulse, Pot of Extravagance (Semi-Limited 2); Labrynth core usage stats: Big Welcome 82.8%, Lovely 75.9%, Arias 69.0%, Infinite Impermanence 51.7%; Arianna and Labrynth Labyrinth absent; Exact archetype purity 9 of 55 copies (16.4%)
• Inferred: Midrange primary with Control secondary from trap count, hand-trap count and the absence of combos; Core opening-hand availability ≈ 0.78; going-second hand-trap availability ≈ 0.76; Interaction and recursion quality from card text regex hits and excerpts; Extra Deck efficiency as a toolbox with partial sub-archetype fit
• Provisional: Meta Power (null) and matchup fit (D13) without a dated metagame sample; Best-of-3 post-side plan (no side deck exists)
• Data gaps: no combos supplied; combo floor, median, and ceiling are text-only no tournament link; archetype meta share and per-pilot records are absent no win-rate telemetry exists in YGOVN; going-first/second and matchup win rates are unknown no Side Deck in the export; post-side performance is unmeasurable deck title is null Meta Power is provisional without a dated metagame sample
