• Secondary strategies: Blind-Second board breaking (Lava Golem / Nibiru package), Trap-based grind (GY recursion), Fiend toolbox Extra Deck
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Out-grind the opponent with recycled Labrynth Normal Traps, then close with Lady Labrynth (3000 ATK), Lovely Labrynth (2900 ATK) or Chaos Angel (3500 ATK).; Going-second blowout: tribute two opponent monsters for Lava Golem, break the rest with Nibiru / Ice Dragon's Prison / Compulsory / Terrors of the Overroot and attack into the opened board.
• Turn 1 (going first): Normal Summon Arianna the Labrynth Servant to add a Labrynth card, Set Welcome Labrynth / Big Welcome Labrynth plus other Normal Traps, then use them on the opponent's turn to summon Lovely or Lady and start the trap-recursion loop.
• Turn 2 (going second): Open with Lava Golem (or Nibiru) to strip the opponent's field, follow with spot-removal Normal Traps (Ice Dragon's Prison, Compulsory Evacuation Device, Terrors of the Overroot, Archfiend's Ghastly Glitch, Dogmatika Punishment), then convert with Lady / Lovely / Chaos Angel.
• Recovery: Lovely sets a Normal Trap from the GY, Lady Special Summons herself when a Labrynth or Normal Trap resolves, Big Welcome banishes itself from the GY to bounce a card, Muckraker From the Underworld recurs a Fiend, and Absolute King Back Jack re-sets a Normal Trap from the top of the Deck.
• After siding: None — the export has a 0-card Side Deck and Duel Links ladder play is best-of-1, so no post-side configuration exists to evaluate.

Why it scores here

This is a 30-card Duel Links Labrynth trap-control shell whose real engine is compact — Arianna, Welcome/Big Welcome, Chandraglier, Stovie Torbie, Lovely and Lady — and whose winning path is grinding with recycled Normal Traps rather than building a large combo board. It opens a Labrynth card often enough (about 70% for one of the six main starter/search copies), so accessibility and the recursion engines carry the deck, while opening-hand quality is dragged down by three main-deck Lava Golem (43% to be in a going-first five and dead there), a near-dead Photon Jumper and 13 single-copy slots. No boards were recorded (0 combos), so the ceiling, the median and the post-disruption routes are text-based inferences rather than measured values. Going second, the Lava Golem / Nibiru / removal-trap package is genuinely live, which is why going-second scores at least as high as going-first. Archetype usage stats confirm the list resembles a real Labrynth build, but popularity and meta representation earned no points here, and the score is a judgement of the system — not an average of the individual card scores.

Dimension scores

How the score was computed

Strategy profile: 0.75 Control + 0.25 Blind-Second / OTK. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Hard-garnet burden (-3); Non-functional Extra Deck slots (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + modifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.7 · key two-card combo ≈ 0.4 · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Compact, coherent Labrynth trap engine with genuine GY recursion (Lovely, Big Welcome, Lady, Muckraker) that wins long games.
• Lovely Labrynth stops monster-effect responses to your Normal Traps, which turns every one-for-one trap into a protected interaction.
• Lady Labrynth is untargetable and indestructible while a Set card is on board, making her a sticky 3000 ATK closer in a 4000-LP format.
• Real going-second package: Lava Golem at 3 copies (50% in a 6-card hand) plus Nibiru and five spot-removal Normal Traps.
• Six starter/search copies give about 70% to open a Labrynth play, and 16 of the 25 usage-tracked core cards are present.

Weaknesses

• Three Lava Golem are dead in the going-first opener and lock out the Normal Summon when used.
• Thirteen single-copy slots mean low redundancy; losing the one Welcome Labrynth or Arianna often ends the turn's development.
• Welcome Labrynth restricts Special Summons from Deck/Extra to Fiends, cutting off most of the Extra Deck toolbox whenever it resolves.
• Golden Cloud Beast - Malong x2 in the Extra Deck is uncastable with no Tuner in the Main Deck.
• Pot of Extravagance randomly banishes 3-6 Extra Deck cards and turns off further draws, fighting the Dogmatika Punishment / N'tss line.
• No Side Deck and no recorded boards: matchup adaptation and post-disruption lines cannot be verified.

Critical choke points

• Arianna the Labrynth Servant and Welcome Labrynth are the only real entry points; negating the search or the summon leaves a passive turn.
• Welcome Labrynth's Fiend-only Special Summon lock closes the Chaos Angel / Underworld Goddess lines for the rest of that turn.
• Lava Golem's 'cannot Normal Summon/Set the turn it is Special Summoned' clause blanks the engine turn when it is used.
• No Tuner exists in the Main Deck, so two Extra Deck slots are permanently dead.
• Dogmatika Punishment's Extra Deck lock and Pot of Extravagance's banish both starve the same limited Extra Deck.

Evidence & confidence

• Verified: Deck is legal under BanDuelLink: 30 Main / 9 Extra / 0 Side within 20-30, 0-9, 0-9 size rules with no violations.; Bystial Druiswurm runs 1 copy against a Semi-Limited limit of 2; Photon Jumper runs 1 against a Semi-Limited limit of 2.; Lovely Labrynth of the Silver Castle: opponent cannot activate monster effects in response to your Normal Trap activations; sets a Normal Trap from the GY.; Lady Labrynth of the Silver Castle: untargetable and indestructible by opponent's card effects while you control a Set card; 3000 ATK.; Welcome Labrynth locks Special Summons from Deck/Extra to Fiends until the end of the next turn after it resolves.; The Main Deck contains no Tuner monster, while the Extra Deck contains two Golden Cloud Beast - Malong (a Synchro Tuner requiring 1 Tuner).; Composition: 18 Effect Monsters, 9 Normal Traps, 3 Spells in the Main Deck; 21 distinct main-deck cards with 13 singletons.
• Observed: Usage statistics: 16 of 25 tracked archetype core cards are present (64%); typical Big Welcome count 3 vs 2 here, typical Arianna count 3 vs 2 here.; Hypergeometric table from the resolved list: 2-copy cards appear in 31.0% of going-first 5-card hands; the 6-copy starter/search group is 70.2%.; Zero recorded combo boards (combo data.total combos = 0), so no measured floor, median or ceiling exists.
• Inferred: About 70% to open at least one Labrynth starter/search card, but only a handful of follow-up engine pieces behind it.; Lava Golem at 3 copies is 43.4% to be in a going-first five where it does nothing.; Full-brick rate estimated near 12% for hands with only breakers/hand traps and no engine or usable trap.; Resilience is trap recursion rather than route redundancy; losing the single Welcome/Arianna line usually ends the turn.; Two Malong slots are permanently dead value in a 9-card Extra Deck.; Going-second power is at least as high as going-first because Lava Golem, Nibiru and the removal traps are all live there.
• Provisional: Meta Power is null: no dated metagame sample and no tournament link were supplied.; Matchup coverage and format fit cannot be scored without archetype meta-share or a per-pilot match record.; Side Deck adaptability is unscoreable: 0 side cards and best-of-1 Duel Links ladder.
• 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 (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied. usage statistics marks Elder Entity N'tss and Underworld Goddess of the Closed World as 'in this deck: false' while both appear in the resolved Extra Deck — the card list was treated as the source of truth. No Duel Links skill information was provided, which can materially change a Duel Links deck's consistency.
