Labrynth Deck #773153 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±8 · Confidence: Medium)

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

Legality

Main 57 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Labrynth Normal Trap engine recurs Fiend starters and grinds the board open, then closes with Lady Labrynth or Lovely Labrynth (ATK 3000 / 2900) and Extra Deck boss monsters; Five-Headed Dragon, Chaos Angel and the Fusion/Synchro/Xyz bosses as late-game closers once the board is cleared
• Turn 1 (going first): T1 Normal Summon or Set a Labrynth starter (Arianna, Chandraglier, Stovie Torbie, Cooclock, Back Jack) and Set a Welcome Labrynth or Big Welcome Labrynth; use Normal Trap recursion from the GY to keep a second line open
• Turn 2 (going second): Hand-trap and Normal Trap interaction (Ghost Ogre & Snow Rabbit, Mirror Force, Typhoon, Terrors of the Overroot) to answer the opponent's board, then rebuild through Labrynth recursion
• Recovery: Recycle Normal Traps and Labrynth monsters from the GY via Stovie Torbie, Chandraglier and Cooclock, and rebuild with Labrynth Set-Up or Labrynth Labyrinth
• After siding: No side deck in this list; post-side adaptation is not possible without changing the main deck

Why it scores here

The deck's power comes from the system as a whole: ten Labrynth-core copies give about a 63% chance of at least one core starter in a 5-card opening hand (Inferred, hypergeometric), and the Normal Trap recursion engine (Stovie Torbie, Chandraglier, Cooclock, Lovely Labrynth) lets the deck rebuild from the graveyard. Interaction is the strongest area, with 27 removal-text and 5 negation-text cards and two hand traps. Combo ceiling and floor are not scored from recorded boards because none were supplied, so those dimensions are text-only inference. Popularity was not credited: the archetype core inclusion stats only confirm that this is a standard Labrynth build. The score was not an average of the individual card scores. The absence of a side deck and of any tournament or matchup data caps the score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Control secondary (about 80/20 by weight). Structural ≈ 55, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: No side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural ≈ 55.1, TR 48, modifier -3 → ≈ 51)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.63 · 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

• Large Normal Trap engine with GY recursion, giving repeatable value
• Layered interaction: removal and negation text on 27 and 5 cards, plus two hand traps
• Strong late-game closers: Lady Labrynth, Lovely Labrynth, Five-Headed Dragon, Chaos Angel
• Standard archetype core, confirmed by usage stats (Big Welcome, Lovely Labrynth, Arias, Arianna all present)

Weaknesses

• No side deck, so the deck cannot adapt between games
• Non-monster-heavy main deck (30 of 57) raises brick risk
• Extra Deck is spread over many single-copy bosses from different engines, limiting consistency
• No recorded boards, so combo conversion and floor/median are unmeasured

Critical choke points

• The Normal Trap engine needs a Set Normal Trap plus a Fiend starter, so a hand without a Fiend or Normal Trap is largely dead
• No side deck means a single bad matchup has no answer within the deck

Recommended changes

Evidence & confidence

• Verified: Legal in OCG: 57 main (40–60), 15 extra (0–15), 0 side, no copy-limit or banlist violations; Core Labrynth inclusion: Big Welcome 83%, Lovely Labrynth 76%, Arias 69%, Arianna 59% (usage stats); 27 removal-text cards and 5 negation-text cards in the resolved text; Two hand-trap-flagged cards: Ghost Ogre & Snow Rabbit (×2)
• Inferred: P(≥1 core starter in a 5-card opening hand) ≈ 0.63; Normal Trap recursion provides multiple independent rebuild lines; Brick risk is elevated by the 30 non-monster main-deck cards; Going-second hand quality is supported by Back Jack, Ghost Ogre and Mirror Force; Interaction density is high relative to the 57-card main deck
• Provisional: Matchup and format fit (no dated meta sample or tournament link); Meta power (null)
• 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: going-first/second, matchup and brick rates are Inferred Meta Power is provisional without a dated metagame sample Deck title is null, so the deck name is not available from the export
