Unchained Deck #754562 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±8 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Blind-Second/OTK, Toolbox
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Unchained Soul of Sharvara and Unchained-based Special Summons into Abominable Unchained Soul / Nibiru / Desirae pressure, after hand traps and monster-destruction effects clear the opponent's interaction; Fiendsmith Extra Deck threats (Fiendsmith's Desirae, Fiendsmith's Lacrima) reached through Fiendsmith Engraver and Fiendsmith's Tract searches
• Turn 1 (going first): Open Unchained starters (Sharvara, Buio, Aruha, Abominable Unchained Soul) and Abomination's Prison to search an Unchained card, then build a field of Fiend monsters while keeping Ash and Maxx C for the opponent's response
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Tour Guide and Nibiru as hand traps to stop the opponent's first summon chain, then convert the surviving hand into Unchained Special Summons
• Recovery: Rebuild from the Graveyard through Unchained Soul of Shyama, Escape of the Unchained, Abominable Chamber of the Unchained and Abominable Unchained Soul revival effects; Droll & Lock Bird and Ash Blossom spread out the opponent's draws
• After siding: Not applicable: Master Duel has no Side Deck, so the deck has no post-side plan and the Side-adaptability score reflects that absence

Why it scores here

The deck's Structural score comes from how it behaves as a system: the Unchained core (21 copies, present in 98% of opening 5-card hands by the hypergeometric proxy) makes an engine live early, and the 10 searcher-text cards (about 78% for at least one in hand) keep it fed. Its interaction density is the strongest signal, with Ash Blossom, Droll & Lock Bird, Maxx "C", Nibiru, Tour Guide and Crossout Designator all covering different timings, which drives D7 and D8. Median output and combo ceiling (D3/D4) are scored from text only because the export contains no parseable boards, so they carry wide uncertainty. Archetype popularity (usage statistics showing the Unchained core as standard) confirms the list is real and accessible but did not add points by itself, and the scores were not averaged from individual card scores. The Fiendsmith sub-build (11 copies plus Extra Deck pieces) shares the Fiend type and dilutes Unchained purity to 30.9%, which costs a few points of engine cohesion and earns a modest negative modifier.

Dimension scores

How the score was computed

Strategy profile: Control primary; Blind-Second/OTK considered for D8/D9 emphasis but the Control profile was kept as the base weight set. Structural ≈ 61, Going First ≈ 56, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: banlist_exposure (-2); engine_conflict_fiendsmith_subbuild (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers (-4) = 0.80*61.4 + 0.20*60 - 4 ≈ 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense, layered interaction across hand traps, on-field negations and destruction effects
• Large Unchained core gives near-certain engine access in the opening hand
• Strong going-second hand-trap density

Weaknesses

• No recorded boards, so the combo ceiling and median output are inferred from text only
• Dilution from the Fiendsmith sub-build lowers Unchained cohesion
• Several Limited/Semi-Limited staples cap resilience if restricted cards are needed twice

Critical choke points

• Unchained Soul of Sharvara and the Unchained Special Summon restriction, since losing the summon piece blocks most engine lines
• Limited Maxx "C" and Crossout Designator as the main answers to a key opposing play

Evidence & confidence

• Verified: Legal status: 40 Main, 15 Extra, 0 Side against Master Duel size rules; Restricted copies: Crossout Designator 1 (Limited), Maxx "C" 1 (Limited), Droll & Lock Bird 2 (Semi-Limited), all within limits; Archetype purity 30.9% (17 of 55 archetype-named copies are exact Unchained); Card text for all 40 Main and 15 Extra cards from the evidence excerpts
• Observed: Usage statistics show the Unchained core as standard (Unchained Soul of Sharvara, Ash Blossom, Droll & Lock Bird, Escape of the Unchained at 75–100% inclusion)
• Inferred: Starter access ≈ 0.98 for the Unchained core and ≈ 0.34 for Sharvara in hand5 (hypergeometric); Interaction density is the deck's strongest dimension (Ash, Droll, Maxx C, Nibiru, Tour Guide, Buio, Crossout); Going-second hand-trap density ≈ 0.71 for at least one hand trap in hand6
• Provisional: Meta Power (no dated metagame sample); Matchup fit (D13) and matchup variance; Tournament reliability inputs beyond structural estimates
• 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 (going-first/second, matchup, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics in_this_deck flags contradict the card list for several Extra Deck cards (Unchained Soul Lord of Yama, Fiendsmith's Sequence, Fiendsmith's Requiem, A Bao A Qu marked in_this_deck false although present with zone extra), so core_present_pct 56% is unreliable Master Duel has no Side Deck, so D12 has no performance data
