Unchained Deck #647809 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Evil Twin / Live Twin Link and Fiendsmith Fusion boards closing through 3000+ ATK Link and Synchro monsters (Evil Twin's Trouble Sunny, Chaos Angel, A Bao A Qu); Unchained recursion boards via Unchained Soul Sharvara and Unchained Soul Lord of Yama, backed by 1-copy negates
• Turn 1 (going first): Open a Live Twin starter (Live Twin Ki-sikil or Lil-la), search with Secret Password or Live Twin Sunny's Snitch, and Link into Evil Twin monsters while holding Ash Blossom and Infinite Impermanence
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash Blossom, Effect Veiler, Droll and Lock Bird, Nibiru) to break the opponent's first board, then rebuild through Evil Twin Link and Fiendsmith Engraver
• Recovery: Recover from a negated starter via GY effects of Live Twin and Evil Twin Lil-la / Ki-sikil and the Unchained Abominable Chamber Set; limited by only one archetype core copy in the Main Deck
• After siding: No Side Deck is run (side_count 0); post-side adaptation is not available in Master Duel as built

Why it scores here

This list is Illegal in master-duel because it runs one copy of Called by the Grave, which is Forbidden, so the score is a structural read capped at 30 and is not a normal contextual score. The system has a real Live Twin / Evil Twin Link engine with 3 copies of each starter-searcher pair, about 13 negation-text cards and 10 hand traps, which gives it reasonable interruption resilience and going-second hand-trap density (about 85 percent to have one in a 6-card hand, Inferred). Its weaknesses are a loose engine that mixes Fiendsmith, Unchained, Knightmare, Chaos, D/D and Fabled pieces (only 5.5 percent exact-name archetype purity), no parseable combo boards, and no side deck. Popularity did not earn points: the Unchained core usage stats confirm the archetype is real, but most core cards (Sarama, Abominable Unchained Soul, Lord of Yama, Shyama) are absent from this list. The score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: 0.8 Combo + 0.2 Stun for Structural is not used; the Combo profile is applied as stated. Structural ≈ 51, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 47. Modifiers: Banlist exposure (-8); Engine conflicts (-3). Final formula: No-meta formula: 0.80*Structural(51) + 0.20*TournamentReliability(47) + ContextModifiers(-11) = 39 before the Illegal cap; Illegal list capped at 30 and labelled theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Three copies of each Live Twin starter and searcher
• Ten hand traps and 13 negation-text cards give going-second interaction density
• Link and Synchro endboard reaches 3000+ ATK

Weaknesses

• Illegal in master-duel due to Forbidden Called by the Grave
• Low exact-name archetype purity (5.5 percent) and mixed engines
• No Side Deck and no post-side plan
• No parseable recorded combos to ground the ceiling or median

Critical choke points

• Live Twin Ki-sikil or Lil-la starter draw in the opening hand (about 34 percent per 3-copy starter in 5 cards)
• Single-copy Unchained Soul core, which is one of the archetype's standard cards and is largely absent

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 counts match the master-duel size rules; Called by the Grave is Forbidden with 0 legal copies and 1 copy run; Droll and Lock Bird Semi-Limited at 2 copies; Crossout Designator Limited at 1 copy (both legal); Archetype purity 5.5 percent and core presence 28 percent from usage statistics
• Observed: Archetype usage confirms Unchained core cards are played (100 percent inclusion for core Unchained Soul cards)
• Inferred: Opening-hand starter and hand-trap probabilities from hypergeometric estimates; Interaction density and resilience from card text; Going-first and going-second strength estimates
• Provisional: Meta Power (null); Matchup fit (D13); Post-side plan (D12, 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 hand-trap rates Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
