Mitsurugi Deck #773852 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

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

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Mitsurugi Ritual Monsters (Ame no Murakumo, Futsu no Mitama, Ame no Habakiri) and K9 Xyz boss monsters (K9-X Werewolf, K9-66X Jacks, K9-17 Ripper) converting their board advantage into attacks.; Dragluxion and Number-series Xyz monsters as Extra Deck follow-up when the K9 or Mitsurugi lines are interrupted.
• Turn 1 (going first): Open Pre-Preparation of Rites or Mitsurugi Prayers for a Mitsurugi/K9 searcher, Normal Summon Mikoto or K9 monsters, then Mitsurugi Ritual or Mirror into a Ritual Monster and Xyz Summon a K9 boss while Ash Blossom and Droll stay up for interruption.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, and Maxx "C" to break the opponent's search and draw lines, then rebuild from a K9 or Mitsurugi searcher and a single Ritual or Xyz follow-up.
• Recovery: Recover through Mitsurugi Great Purification (GY banish to Special Summon a Reptile), Mikoto recursion from GY or banishment, and the Pre-Preparation and Mikoto searches that re-find engine pieces.
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-3.

Why it scores here

The deck opens a functional plan reliably: searchers (18 searcher-text cards) plus a 24-copy archetype core give roughly a 99% chance of at least one core piece in a 5-card opening hand (Inferred hypergeometric). Its ceiling comes from Mitsurugi Ritual Monsters and K9 Xyz bosses, with Ash Blossom, Droll & Lock Bird, Maxx "C", Great Purification, and Murakumo giving layered interaction on the system. The score comes from consistency, recovery, and interaction on the whole system; it does not reflect the popularity of the Mitsurugi archetype, and no card scores were averaged. Median output, going-second conversion, and post-side adaptability are weaker: there are no recorded boards and no Side Deck, which caps the score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Combo secondary (primary-weighted; secondary weights not applied separately). Structural ≈ 63, Going First ≈ 66, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist_exposure (-2); engine_split (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Dense searcher suite (18 searcher-text cards) gives high access to the engine on turn 1-2
• Layered interaction: Ash Blossom, Droll & Lock Bird, Maxx "C", Great Purification, Murakumo negate, Crossout Designator
• Multiple starters and recursion (Mikoto, Great Purification, Pre-Preparation) support recovery after disruption
• Strong Xyz and Ritual boss ceiling (K9-X Werewolf 3300 ATK, Murakumo 3200 ATK)

Weaknesses

• No Side Deck: no post-side adaptation in a best-of-3
• Only 21% exact-name archetype purity; K9, Mitsurugi, and Mulcharmy compete for slots
• Mulcharmy draw effects need an empty field and are dead in many hands
• No recorded combos or tournament data, so the median output cannot be confirmed

Critical choke points

• Ritual and Xyz summons depend on Mitsurugi Ritual or Mirror plus Reptile tributes; losing those pieces to Droll or an early hand trap stalls the Ritual line
• K9 summon conditions require the opponent to hold 2+ cards in hand, which is not guaranteed

Recommended changes

Evidence & confidence

• Verified: Main 42, Extra 15, Side 0; legal under master-duel size rules (40-60 main, 0-15 extra, 0-15 side); Banlist: Maxx "C", Mitsurugi Prayers, Crossout Designator Limited; Ame no Habakiri and Droll & Lock Bird Semi-Limited; Archetype composition: 12 exact Mitsurugi, 16 K9, 6 Mulcharmy, 21.1% exact-name purity
• Observed: Core Mitsurugi cards (Maxx "C", Saji, Prayers, Mirror) show 100% inclusion in the usage statistics
• Inferred: Opening-hand probability of at least one searcher ≈ 0.95 (hypergeometric); Brick, recovery, and interaction quality scores from card text and composition; Going-first and going-second power estimates
• Provisional: Meta Power is null; D13 is a neutral placeholder (no dated meta sample or tournament link)
• 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 deck title is null and no Side Deck is registered
