Labrynth Deck #771641 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 41 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Labrynth and Ashtra Synchro/Link boards (Ashtraja Susanoo, Chaos Angel, Lady/Lovely Labrynth of the Silver Castle) pressured through a Normal Trap engine that searches and recurs its own Labrynth pieces; Trap-based negation and removal (Infinite Impermanence, Songs of the Dominators, Dominus Impulse) that clears interruption and protects the board
• Turn 1 (going first): Open a Labrynth starter (Arianna, Big Welcome Labrynth, Welcome Labrynth) to search or summon a Labrynth follow-up, then set Normal Traps to protect the engine
• Turn 2 (going second): Use hand traps (Infinite Impermanence, Nibiru, Dominus Impulse) to disrupt the opponent's summon-heavy turn, then rebuild through Normal Trap recursion and the Extra Deck
• Recovery: Recur Normal Traps and Labrynth monsters from the GY (Labrynth Stovie Torbie, Labrynth Chandraglier, Labrynth Cooclock) and use Lovely Labrynth to re-set Normal Traps
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan in the evidence

Why it scores here

The deck is Illegal as submitted: Dominus Impulse is run 3 times against an OCG Semi-Limited limit of 2, so per the rubric it receives a capped, structural-only score of 30 rather than a normal Final Contextual score. Its structural read is moderate: about 77% of hands open at least one of the 10 Labrynth/Ashtra core copies and about 83% open a searcher-text card (both Inferred hypergeometric estimates), and the Normal Trap engine recurs its own pieces from the GY, which supports resilience. Interaction is the strongest area, with 6 hand traps, 11 negation-text and 9 removal-text cards, and a 64% chance of at least one hand trap in a going-second six-card hand. The deck has no recorded boards, no tournament link and no side deck, so its ceiling and median output are text-only inferences and its post-side score is minimal. Popularity of the archetype and the card-level scores were not averaged or used to raise the score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 52, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist and copy-limit violation (-6); No side deck (-4); Illegal cap (-13). Final formula: Formula 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 42.8 before cap; capped at 30 because the deck is Illegal (no normal Final Contextual score); Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.77 · key two-card combo ≈ — · full-brick estimate ≈ 0.23 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Interaction density: 6 hand traps, 11 negation-text and 9 removal-text cards
• Normal Trap recursion and Labrynth searchers give real resilience across turns
• Broad Extra Deck coverage of high-ATK synchro and link finishers

Weaknesses

• Illegal as submitted: Dominus Impulse over the copy limit
• No side deck, so no best-of-3 adaptation
• Low archetype purity (25% exact name) and 42 off-archetype copies dilute the engine

Critical choke points

• A single Normal Trap or Labrynth starter in the opening hand gates the whole line; ~23% of hands lack any core copy
• Dominus Impulse is over the limit and must be cut before the list is playable

Recommended changes

Evidence & confidence

• Verified: Illegal status: Dominus Impulse 3 copies vs legal limit 2 (Semi-Limited); Main 41 (40-60 legal), Extra 15 (0-15 legal), Side 0 (0-15 legal); Archetype core share: Big Welcome Labrynth 83%, Lovely Labrynth 76%, Arianna 59%, Infinite Impermanence 52%; Arias the Labrynth Butler 69% and Labrynth Labyrinth 52% missing
• Inferred: P(at least one core starter in opening 5) = 0.77 and proxy brick 0.23 (hypergeometric); Interaction density from text flags (6 hand traps, 11 negation, 9 removal); Going-second hand trap probability 0.64 (hypergeometric); Boss-level ATK on the Extra Deck from card data
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry; going-first/second, matchup and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied deck title is null in the export no side deck supplied (0 cards)
