Mitsurugi Deck #762223 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Ritual/Tribute engine
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo no Mitsurugi via Mitsurugi Ritual (3200 ATK; its Special Summon destroys all opponent monsters), with Ame no Habakiri no Mitsurugi (-800 ATK to opposing monsters) as the second ritual boss; Extra Deck beats from Synchro, Link and Xyz monsters (TY-PHON, Malong, Dyna Mondo, Packbit) once the opponent's board is cleared
• Turn 1 (going first): Open a Reptile searcher (Aramasa, Saji, Kusanagi or Lamia), use it to fetch the Ritual Spell or a Ritual boss, and keep Ash Blossom, Infinite Impermanence or Maxx C up to protect the line from a single interaction
• Turn 2 (going second): Use the six-card hand and the 7 main-deck hand traps to stop the opponent's first summon, then ritual into Murakumo or Habakiri to take the board
• Recovery: Rebuild through Futsu no Mitama (GY revival of a Reptile) and Mitsurugi Great Purification (banish from GY to revive a Reptile), and use Lamia's banish effect to protect a Reptile
• After siding: Bring in Evenly Matched or Ghost Belle against a board-heavy opponent and Droll & Lock Bird against a card-draw deck; Dimensional Fissure is a floodgate option against GY-heavy decks

Why it scores here

The deck's consistency rests on a system, not on any single card: 18 searcher-text cards and four Reptile searchers (Aramasa, Saji, Kusanagi, Lamia) give a 96 percent chance of at least one searcher in an opening hand of five, while the Ritual Spell routes are narrower (Mitsurugi Ritual at three copies gives about 34 percent going first). Seven main-deck hand traps (Ash Blossom, Infinite Impermanence, Maxx C) and the negate-plus-revival package (Mitsurugi Great Purification, Futsu no Mitama, Dominus Impulse) make the deck interaction-dense, which drives the endboard and going-second scores. The ceiling is Ame no Murakumo's Special Summon wipe followed by a 3200-ATK attack; the median is unmeasured because no recorded boards exist, so the median score is an inference from the text only. Popularity did not earn points: the archetype core coverage is inconsistent in the evidence, and the score was not built by averaging card scores. The deck is penalized for a single Mitsurugi Ritual choke point, the Reptile-tribute conflict between searchers and Ritual costs, and the Limited status of Maxx C and Mitsurugi Prayers.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (disclosed; weights taken from the Midrange profile). Structural ≈ 62, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Banlist exposure (-1); Engine conflict (-1); Unrecoverable choke point (-2); Engine compactness (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*62 + 0.20*58 - 3 = 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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 density (18 texts) gives a high starter-in-hand rate
• Seven hand traps plus negates provide layered interaction
• Murakumo gives a board-wipe ceiling; Habakiri gives a second ritual boss
• Revival options (Futsu, Great Purification) let the deck rebuild from the GY

Weaknesses

• Single Ritual Spell choke point (3 Mitsurugi Ritual plus Mirror)
• Reptile-tribute conflict between searchers and Ritual costs
• Droll & Lock Bird is the guide's main danger; only 2 copies in the side deck
• Off-archetype Extra Deck slots reduce engine coherence

Critical choke points

• Mitsurugi Ritual and Mitsurugi Mirror (Ritual access)
• Mitsurugi Prayers (Limited searcher)
• A GY banish-heavy opponent turns off the GY revival lines

Recommended changes

Evidence & confidence

• Verified: Legal under BanMasterDuel: main 40, extra 15, side 15; Limited and Semi-Limited copy counts comply; Card stats and text for all 40+15+15 cards; Archetype exact-name purity 30.9 percent (17 of 55 main-deck copies)
• Observed: Vietnamese guide snippet: Droll stops the engine, GY-banish decks are feared, Xyz rank 4 and 8 play
• Inferred: Consistency estimates from hypergeometric draws; Interaction density (Inferred semantic read of card text); Brick risk and going-second hand-trap read
• Provisional: Meta power and matchup fit (no dated metagame sample); Post-side plan performance
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent usage_statistics in_this_deck flags are inconsistent: King of the Feral Imps, S:P Little Knight, Dugares, Masquerena and Dyna Mondo are in the Extra Deck list but marked in_this_deck false and reported as missing core; core_cards_present (14) counts only main/side, so core coverage 56 percent is unreliable no win-rate telemetry (going-first/second, matchup, brick and OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
