Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Toolbox
• Format: duel-links

Legality

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

Identity & game plan

• Win condition: Trap-driven board control with Labrynth monsters (Lady and Lovely Labrynth, 2900-3000 ATK) and Lord of the Heavenly Prison as the closers, following the Normal Trap loop (Welcome / Big Welcome Labrynth); Nibiru, the Primal Being as a hand-trap-style 3000 ATK swing when the opponent summons 5 or more monsters in a turn
• Turn 1 (going first): Set Welcome Labrynth or Big Welcome Labrynth on T1, activate it through a Labrynth monster from hand (Arianna, Arias, Cooclock, Stovie) to Special Summon a Labrynth and recycle the trap into the GY for the next engine step
• Turn 2 (going second): Hold Ice Dragon's Prison and Nibiru as interaction, use Normal Trap activations on the opponent's turn to clear a monster and then land Lady or Lovely Labrynth
• Recovery: Recover from the GY: Labrynth Chandraglier, Stovie and Cooclock can be added or Special Summoned when a Normal Trap leaves the field, and Lovely Labrynth can Set a Normal Trap back from the GY
• After siding: Not applicable: Duel Links has no Side Deck (side_count 0)

Why it scores here

The deck is a Labrynth Normal Trap control list in Duel Links: 11 trap cards plus Labrynth Labyrinth, with 18 exact-name Labrynth copies in the 30-card Main Deck. Its reliable part is the Welcome-family trap loop, which has about a 63% chance of at least one of its five copies in a going-first opening hand (Inferred hypergeometric estimate), and it gets recursion from the GY through Chandraglier, Stovie, Cooclock and Lovely Labrynth. Its interaction is spread across Ice Dragon's Prison, Ghastly Glitch, Dogmatika Punishment, Terrors of the Overroot and Compulsory Evacuation Device, so it can answer a board in layers rather than with one card. The main weakness is the Extra Deck: its nine singletons come from nine unrelated sources (Chimera, Berfomet, Knightmare, Chaos, Gallant Granite, Dugares, Muckraker, N'tss, Underworld Goddess) and none is a Labrynth, so the Extra slots add little to the engine and the list has no recorded combo evidence to raise its ceiling. The score comes from consistency, recursion and interaction on the system as a whole, not from Labrynth being a known archetype and not from averaging card scores; the absence of combos, tournament data and win-rate telemetry keeps the band wide.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflicts / unrelated Extra Deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 52.15*0.80 + 52*0.20 = 52.1, then modifiers = -3 => 49

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

• Legal, complete Main Deck (30) and Extra (9) for Duel Links with no copy-limit violations
• Recursion from the GY across several Labrynth monsters supports rebuilding after interruption
• Layered trap-based interaction covers different board states
• Welcome-family starter density (5 copies) gives the engine a reasonable opening chance

Weaknesses

• No Labrynth monster in the Extra Deck; nine unrelated singletons add little
• No recorded combos, so the ceiling and median are unverified
• Eleven generic traps and Labyrinth are not archetype-pure (46.2% exact-name purity)
• Closing power depends on a few single-copy monsters (Lady, Lovely, Lord, Nibiru)

Critical choke points

• Normal Trap activation: most of the engine stops if no Normal Trap can be Set or activated
• Single-copy Lady and Lovely Labrynth are the main end-board payoffs

Recommended changes

Evidence & confidence

• Verified: Legal status, size counts 30/9/0, copy histogram 13/4/3 and hypergeometric draw odds match the resolved list; Archetype purity 18 exact-name Labrynth copies out of 39 (46.2%); Interaction cards and their text (Ice Dragon's Prison, Ghastly Glitch, Dogmatika Punishment, Terrors, Compulsory Evacuation Device)
• Observed: Usage statistics confirm Labrynth core cards (Welcome, Arianna, Arias, Lovely, Lady) are standard in this archetype
• Inferred: Going-first starter probability and brick rate; Interaction layering and recursion value; Going-second strength of Nibiru and Ice Dragon's Prison; Control primary strategy from the trap-heavy composition and guide text
• Provisional: Meta power (no dated metagame sample); Format fit and matchup coverage (no tournament_context); Post-side plan (Duel Links has no Side Deck)
• 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 for going-first, going-second, matchup, brick or starter rates Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics in_this_deck flags contradict the cards list for 8 Extra Deck cards (Knightmare Phoenix, Muckraker, Underworld Goddess, Chaos Angel, Elder Entity N'tss, Berfomet, Chimera, Dugares show in_this_deck false but appear in cards with zone extra); the in_this_deck and missing_core values were not relied on for scoring guides_evidence snippets are thin (section_count 0 on both guides)
