Labrynth Deck #768081 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Labrynth Normal Trap engine (Welcome / Big Welcome / Lovely Labrynth) recurring Fiend and Labrynth monsters into high-ATK Link, Xyz, Synchro and Fusion finishers (Inferred from card text; no recorded boards); Extra Deck boss monsters such as Chaos Angel, Bucephalus II, Super Starslayer TY-PHON and Underworld Goddess once the board is established (Inferred)
• Turn 1 (going first): Open a Labrynth starter (Arianna, Arias, Chandraglier, Big Welcome) and set a Normal Trap to build a Fiend-based board; keep Ash and Infinite Impermanence up for interaction (Inferred)
• Turn 2 (going second): Use the six-card hand to hold hand traps (Ash, Nibiru, Evenly Matched, Impermanence, Daruma) against the opponent's first summon, then convert through Labrynth recursion (Inferred)
• Recovery: Recur Labrynth Cooclock, Labrynth Stovie Torbie and Chandraglier from the GY through Normal Trap activations; Labrynth Set-Up returns spells and traps to the Deck (Inferred)
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adjust between games (Verified: side_count 0)

Why it scores here

This list is Illegal in OCG: Ash Blossom & Joyous Spring is run 3 times against a limit of 2, and S:P Little Knight is run 2 times against a limit of 1, so the score is capped and labelled theoretical only. Structurally the Labrynth Normal Trap engine gives a reasonably accessible starter (about 0.86 chance of at least one archetype-core card in a 5-card opening, Inferred) and a strong interaction package of 11 hand traps and 14 removal-text cards. The score comes from consistency, interaction and closing power on the system as a whole, not from averaging the individual card scores, and popularity is not counted: the Labrynth archetype is in usage stats, but that only shows the list is real. Median output and combo conversion are weak because no recorded boards exist, so those dimensions are text-only inference, and the deck has no Side Deck and only 38.6% exact archetype purity.

Dimension scores

How the score was computed

Strategy profile: Midrange primary (≈85%) with Combo secondary (≈15%) for the Labrynth Normal Trap engine. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-8); off-archetype density (-4). Final formula: Final = 0.80*Structural + 0.20*TournamentReliability + Modifiers = 0.80*57.1 + 0.20*52 - 12 ≈ 44; Illegal-status cap applied to 35 (theoretical only; Meta Provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Large, accessible archetype core (13 copies, 0.86 chance of at least one in opening 5)
• 11 hand traps and 14 removal-text cards give layered interaction
• Several 2900-3500 ATK finishers in the Extra Deck
• Recursion from the GY supports grind

Weaknesses

• Illegal copy counts: Ash Blossom and S:P Little Knight are over the OCG limit
• No Side Deck, so no post-side plan
• Low archetype purity (38.6%) and mixed Extra Deck engines
• No recorded boards, so combo conversion and median output are unverified

Critical choke points

• Illegal copy counts must be fixed before any normal rating applies
• Single Normal Trap activation window needed for most Labrynth lines

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 vs 2 legal copies; S:P Little Knight 2 vs 1 legal copies; Main 42 and Extra 15 are within size rules; Side 0; Card text and ATK/DEF values from the evidence pack; Archetype core inclusion 83% from usage stats
• Inferred: Opening-hand consistency (0.86 starter access); Interaction quality from text role hints; Combo conversion and recovery from card text; Going-first and going-second plans
• Provisional: Meta Power (null); Matchup and format fit (no dated meta sample)
• 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 exists in YGOVN — going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered (side_count 0)
