Labrynth Deck #769964 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Normal Trap chain into Labrynth board presence, finished by Lady Labrynth of the Silver Castle (3000 ATK) and Lovely Labrynth (2900 ATK) with Extra Deck boss support.; Extra Deck finishers (Chaos Angel, Underworld Goddess of the Closed World, Super Starslayer TY-PHON, Number 1: Infection Buzzking) once the board is cleared or the opponent has committed.
• Turn 1 (going first): Set Welcome Labrynth / Big Welcome Labrynth and use Arianna, Arias, Ariane, Stovie or Cooclock to search or Special Summon Labrynth pieces, then chain Normal Traps into Lady or Lovely.
• Turn 2 (going second): Use Ash Blossom, Maxx C, Infinite Impermanence and Dogmatika Punishment to answer the opponent's first board, then rebuild through Normal Trap recursion from the GY.
• Recovery: Recycle Normal Traps and Labrynth monsters from the GY (Stovie Torbie, Chandraglier, Lovely's Normal Trap recursion) and rebuild a Labrynth board from the Deck.
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games.

Why it scores here

The deck reliably opens a Labrynth core: the archetype core group has P(at least one copy in a 5-card opening hand) of about 0.92, and the proxy for no core card in hand is about 0.08. Its strength is on the system level: 15 Normal Traps feed a chain of search, recursion and Special Summon effects, and the 6 hand traps (Ash Blossom x2, Maxx C, Infinite Impermanence x3) plus Lady and Lovely give layered interaction and strong end-board bodies. The score does not come from Labrynth being a popular archetype, and it does not come from averaging card scores; the Labrynth-specific Normal Trap dependency and the 15-card Extra Deck are what drive the reading. The main weaknesses are the absence of any recorded boards (the combo floor and median are text-only inference), an empty Side Deck that gives no post-side adaptation, and a high pilot-complexity burden from timing Normal Trap activations.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 62, Going First ≈ 66, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-2); empty_side_deck (-2); engine_compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*62.4 + 0.20*55 = 60.9, then context modifiers -2 = 58.9, rounded to 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core Labrynth group is present in about 92% of 5-card opening hands (Inferred).
• Six hand traps and layered end-board interaction (Lady, Lovely, Daruma, Big Welcome, Dogmatika Punishment).
• Extra Deck has high-ATK closers across Synchro, Link, XYZ and Fusion, covering several boss routes.

Weaknesses

• No recorded combo boards, so ceiling, median and floor are text-only inference.
• Empty Side Deck means no matchup adaptation.
• Normal Trap density (15 of 40 main slots) makes trap-only hands dead without a monster to chain into.

Critical choke points

• Normal Trap activations: most engine lines require a Set Normal Trap or a Normal Trap activation from hand.
• Maxx C, Ash Blossom and Pot of Extravagance are single-copy-limited or Semi-Limited, so the hand-trap wall cannot be stacked beyond the cap.

Evidence & confidence

• Verified: Legal in OCG: 40 Main, 15 Extra, 0 Side; within size rules and copy limits.; Restricted cards: Maxx C (Limited, 1), S:P Little Knight (Limited, 1), Ash Blossom (Semi-Limited, 2), Pot of Extravagance (Semi-Limited, 2), all at legal cap.; 15 Normal Traps (race Normal, frame trap), 21 monsters, 4 spells in Main Deck.; Archetype purity 45.5% exact-name; 1 Vietnamese guide attached (snippet only).
• Inferred: P(>=1 core copy in 5-card hand) = 0.919; proxy brick = 0.081.; P(>=1 hand trap in 6-card going-second hand) = 0.650.; Interaction and closing strength read from card text, not from boards.; Going-first and going-second splits are estimated from consistency and interaction.
• Provisional: Meta Power is null; format fit (D13) is provisional with no dated meta sample.; Tournament reliability is estimated from the structure only.
• Data gaps: No parseable combo boards (combos_evidence total_combos = 0). No tournament link; no archetype meta-share or per-pilot match record. No win-rate telemetry for going-first, going-second, matchup, brick or starter rates. Side Deck is empty; post-side performance is unmeasurable. The single guide snippet has no section detail to confirm the intended line.
