Labrynth Deck #772962 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Labrynth Normal Trap chains that Special Summon Fiend monsters and push board presence, closed by Extra Deck threats (Supreme King Z-ARC x2, Odd-Eyes Arcray Dragon, Saint Azamina, Chaos Angel) (Inferred from card text); Link and Fusion beatsticks (A Bao A Qu, Unchained Soul of Anguish, Starving Venom, Brave-Eyes Pendulum Dragon) that attack through a stalled board (Inferred)
• Turn 1 (going first): Open a Labrynth Fiend or Normal Trap and set a Normal Trap; use the Labrynth summon-from-Trap loop to reach a 2-3 monster board and hold Mind Mirror Force / Solemn Accusation behind it (Inferred)
• Turn 2 (going second): Hold Maxx "C", Evenly Matched and Dominus Impulse as hand and set interaction, then use Normal Trap activations to answer the opponent's summon and rebuild a board with Labrynth monsters from the GY (Inferred)
• Recovery: Labrynth GY effects (Labrynth Chandraglier, Labrynth Stovie Torbie, Labrynth Cooclock) re-enter the field from the GY after a Normal Trap resolves, and Ariane / Arianna can draw or search Labrynth cards (Inferred from card text, not tested)
• After siding: Not evaluable: the deck runs no Side Deck (Side Deck size 0), so there is no post-side plan (Verified)

Why it scores here

The score is built on the deck as a system and not on the average of its card scores. The Labrynth core (7 copies of the core set, P(at least one core card in a 5-card opening hand) ≈ 0.51) gives an engine that is live on some openings but leaves about half of hands without a starter, and 35 of 55 Main Deck cards are Trap Cards that need a Labrynth or Fiend monster on the field, which pulls the brick and consistency scores down. Interaction is the deck's strongest area: Mind Mirror Force, Solemn Accusation, Soul of the Supreme King, Dominus Spark, Evenly Matched, Trap Holic and Dominus Impulse give layered negation and removal (inferred from text). Closing power is moderate, with Supreme King Z-ARC and Saint Azamina as the main boards, and the score is capped because the list is illegal: Azamina Ilia Silvia is Forbidden and is run once. Popularity from usage statistics (Big Welcome Labrynth at 82.8%) confirms the list is accessible but did not add points. No combo data, no tournament data, and no side deck exist, so floor, median and ceiling are text-only estimates.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-6); no Side Deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*49 + 0.20*35 = 46.2; modifiers total -10 gives 36.2; illegal-deck cap applied, final score 30 (theoretical / structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.51 · 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

• Layered interaction: Mind Mirror Force, Solemn Accusation, Soul of the Supreme King, Dominus Spark, Evenly Matched, Trap Holic, Dominus Impulse (Inferred from text)
• Redundant recovery through Labrynth GY effects (Chandraglier, Stovie Torbie, Cooclock) (Inferred from text)
• Strong Extra Deck closers: Supreme King Z-ARC x2, Odd-Eyes Arcray Dragon, Saint Azamina (Verified stats)
• Real and accessible list: Big Welcome Labrynth 82.8% and Lovely Labrynth 75.9% usage in the archetype (Verified usage)

Weaknesses

• Illegal list: Azamina Ilia Silvia is Forbidden and cannot be run (Verified)
• High trap density: 35 of 55 Main Deck cards are Traps needing a monster on field (Verified count, Inferred brick risk)
• Core engine only ~51% to appear in a 5-card opening (Inferred)
• No Side Deck (Verified)
• Low exact-name purity (25.7%) across many sub-archetypes (Verified)

Critical choke points

• Labrynth monster on field to enable the Normal Trap loop: if the opening has traps and no monster, the hand is largely dead (Inferred)
• Single-copy engine pieces (Labrynth Cooclock, Arianna, Lovely Labrynth) cannot be replaced once they are used (Verified copy count)
• Illegal Forbidden card in Extra Deck makes the whole list unplayable as-is until it is removed (Verified)

Recommended changes

Evidence & confidence

• Verified: Forbidden card Azamina Ilia Silvia is over copy limit (1 copy vs 0 legal); Main 55 / Extra 15 / Side 0 counts; Usage stats: Big Welcome Labrynth 82.8%, Lovely Labrynth 75.9%, Arias 69.0%, Arianna 58.6%; Maxx "C" Limited (1 copy), Dominus Impulse Semi-Limited (2 copies)
• Inferred: Starter P(≥1 core in hand of 5) ≈ 0.51; Trap density drives brick rate; Interaction density is layered (negation and removal text); Going-second plan via set Normal Traps and Maxx "C"
• Provisional: Meta Power is null: no dated metagame sample; Matchup and format fit (D13) is provisional without tournament data
• Data gaps: Illegal list: a Forbidden card is run, so no normal Final Contextual score is given No parseable combos: floor, median and ceiling are text-only estimates No win-rate telemetry, no tournament link, no dated metagame sample No Side Deck, so post-side adaptability cannot be measured Deck title is null in the export
