Unchained Deck #774272 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

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

Legality

Main 40 / Extra 6 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link Summon Unchained Link monsters (Enma Lord Yama, Unchained Abomination, Abominable Unchained Soul line) off Unchained recursion and destruction-based board development.; Level 8 Fiend recursion through the Dark Spirit monsters and Unchained Soul of Disaster's GY-scaling ATK.
• Turn 1 (going first): Normal Summon Unchained Ogre Shma (3 copies) to Special Summon a Level 4-or-lower Unchained monster from the Deck, or open with Unchained Soul of Sharvara from hand, while Abomination's Prison and Reincarnation of the Unchained fetch the next Unchained piece.
• Turn 2 (going second): Hold Ash Blossom & Joyous Spring and Dark Spirit of Malice / Banishment as hand interaction, use Escape of the Unchained and Iron Thunder on the opponent's board, and rebuild through Unchained Twins - Rakea / Aruha Special Summons from hand.
• Recovery: Reincarnation of the Unchained shuffles GY Unchained cards back to the Deck; Unchained Soul Lord of Yama and Unchained Soul of Shyama can be used from the GY, and Dark Spirit recursion returns Level 8 Fiends.
• After siding: Not applicable: Master Duel has no sideboard (side_count 0, side size rule 0-15 unused), so no post-side adaptation exists to score.

Why it scores here

The 40-card list is legal and compact, with 35 exact-name Unchained copies (76.1% purity) and a hypergeometric estimate of about 92% that at least one archetype core card is in a 5-card opening hand, so the engine usually comes online early. Its strength as a system is in interaction and recursion: three Ash Blossom, two Iron Thunder, three Escape of the Unchained, and Level 8 Fiend recursion give it a dense answer layer and several independent ways to rebuild after one disruption. The main weaknesses are the 11 off-archetype copies, especially three Mulcharmy Fuwalos that only work when you control no cards, and the absence of any combo boards, tournament link, or win-rate data, so the floor and median are inferred rather than observed. The score comes from consistency, interaction, and recovery on the list as a whole, not from averaging individual card powers, and Unchained's popularity (guide evidence, usage rows) was not credited as strength. Meta power remains provisional because no dated metagame sample was supplied.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 62.8, Going First ≈ 65, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: off-archetype dilution (-2); engine compactness (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense, redundant Unchained access: archetype core present in about 92% of 5-card openers
• Layered interaction: three Ash Blossom, two Iron Thunder, three Escape of the Unchained
• Recursion routes (Reincarnation of the Unchained, Lord of Yama, Level 8 Fiend revival) support recovery after disruption
• Compact 40-card main with 6 single-copy Link monsters and no Extra Deck conflicts

Weaknesses

• 11 off-archetype copies dilute the engine, especially three Mulcharmy Fuwalos
• No recorded boards, so the floor and median cannot be measured
• Usage statistics show the deck runs few of the listed core cards (core present 7 of 25); the stat rows appear to be a broader card set, so the deviation is not proof of weakness
• Master Duel has no sideboard, so there is no post-side adaptation

Critical choke points

• Unchained Ogre Shma and Unchained Soul of Sharvara as the hand-based openers; losing both to hand disruption leaves few alternate starters
• Escape of the Unchained and Iron Thunder as the only non-hand-trap answers, each reliant on the Unchained board

Recommended changes

Evidence & confidence

• Verified: Legal main 40 / extra 6 / side 0 under master-duel size rules; All 21 main and 6 extra distinct cards Unlimited under BanMasterDuel; Exact-name archetype purity 76.1% (35 of 46 Unchained-named copies, 11 off-archetype)
• Observed: Unchained usage rows exist (available true) and the deck runs Ash Blossom x3, Sharvara x3, Shma x3 as typical core
• Inferred: P(≥1 archetype core in 5-card hand) ≈ 0.92; full-brick proxy ≈ 0.08; Recovery and interaction ratings from card text (removal 24 hits, negation 7 hits); Going-first and going-second power components
• Provisional: Meta power (no dated metagame sample); Matchup and format fit (tournament_context unavailable); Side deck adaptability (no sideboard in Master Duel)
• 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, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no sideboard; post-side scoring is structurally absent
