Labrynth Deck #771800 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• 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: Synchro boss pressure (Ashtra 3000-ATK synchros, Psychic End Punisher, Ecclesia and the Dark Dragon) backed by hand-trap and negation interaction; Labrynth Lady/Lovely recursion and Normal Trap value; Ashtra revival line
• Turn 1 (going first): Open Labrynth or Ashtra starters (Big Welcome Labrynth, Arianna, Akasuna) and go to a Synchro, keeping Ash Blossom, Infinite Impermanence and Solemn Judgment up for the opponent's first activation
• Turn 2 (going second): Hand traps (Ash Blossom, Droll & Lock Bird, Maxx C, Evenly Matched) to break the opponent's starter, then Synchro through the resulting board
• Recovery: Recycle Normal Traps and Labrynth monsters from the GY with Lovely Labrynth, Big Welcome and Welcome Labrynth; rebuild with Pot of Prosperity or Pot of Sloth
• After siding: Not evaluable: the deck has no Side Deck (0 of up to 15 cards), so no post-side plan exists

Why it scores here

The deck is scored as a system, not as an average of its cards. Consistency is moderate: the core Labrynth set (10 copies, about 65% chance of at least one in a 5-card opening hand per the archetype group estimate) is accessible, but exact-name archetype purity is only 12.9% and the list splits across Ashtra, Dominus, Solemn, Greed, Branded and Mulcharmy, so starters conflict with each other. Interaction is the deck's strongest feature: 17 negation-text and 23 removal-text cards, 9 hand traps, and about a 68% chance of at least one hand trap in a 6-card going-second hand. Popularity is not credited: Labrynth usage stats confirm the core is real, but they do not make the list stronger. No recorded boards exist, so combo ceiling and median are text-only inferences and are scored low. The deck is Illegal (Baronne de Fleur and Albion the Branded Dragon are Forbidden, with 1 copy each), so the Final score is capped at 25 and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: primary 0.85 / secondary 0.15. Structural ≈ 41, Going First ≈ 40, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(41) + 0.20*TournamentReliability(35) = 40; modifiers total -12 gives 28; Illegal-deck cap applied, final 25 (structural-only, theoretical)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 negation and removal coverage: 17 negation-text and 23 removal-text cards
• Strong end-board ATK in the Extra Deck (Ashtraja Susanoo 3300, Psychic End Punisher 3500)
• Core Labrynth set has high inclusion in the archetype usage data

Weaknesses

• Illegal: two Forbidden cards at 1 copy each
• Low exact-archetype purity (12.9%), with starters spread across 6+ sub-archetypes
• No Side Deck, so no post-side plan
• Heavy Level-0 and Trap density (28 Traps, 33 Level-0 cards) reduces draw efficiency

Critical choke points

• Dependence on the Forbidden Baronne de Fleur and Albion slots for the boss/removal plan
• Opening-hand starter access for each sub-engine (about 25% per copy at 5 cards)

Recommended changes

Evidence & confidence

• Verified: Legality: Baronne de Fleur and Albion the Branded Dragon are Forbidden and run at 1 copy each; Main 55 and Extra 15 are within OCG size rules; Side is 0; Copy histogram: 15 singles, 8 doubles, 8 triples; Role-tag counts: 9 hand traps, 17 negation-text, 23 removal-text
• Observed: Labrynth core cards show high archetype usage inclusion (Big Welcome 82.8%, Lovely Labrynth 75.9%)
• Inferred: Starter access about 25% per 3-copy card in a 5-card hand; Hand-trap presence about 68% in a 6-card going-second hand; Consistency and brick estimates from text plus composition
• Provisional: Meta Power (null, no dated metagame); Matchup fit (D13), no tournament data
• 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 in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, and the Side Deck is empty
