Mitsurugi Deck #773834 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo no Mitsurugi (3200 ATK) or a Ryzeal Duo Drive / Xyz board, converting Reptile recursion and Mitsurugi searches into a single large threat; Ryzeal Detonator (3000 ATK) and Galaxy-Eyes Photon Lord as Extra Deck closers once the Ryzeal or Xyz lines are live
• Turn 1 (going first): Turn 1 search through Mitsurugi no Mikoto (Saji or Kusanagi) or Pre-Preparation of Rites, Ritual Summon via Mitsurugi Ritual/Mirror into Murakumo or Habakiri, and keep Ash Blossom and Droll for the opponent's first response
• Turn 2 (going second): Hold Ash Blossom, Droll, Maxx C, Ghost Ogre and Effect Veiler in a six-card hand to stop the opponent's first summon or search, then rebuild through the Reptile GY recursion and Futsu no Mitama no Mitsurugi revival
• Recovery: Reptile monsters in the GY (Saji, Kusanagi, Aramasa, Wousu) and Mitsurugi Prayers/Mitsurugi Mirror re-enable a Ritual Summon, while Ryzeal Duo Drive attaches Ryzeal monsters from the GY as material
• After siding: No Side Deck is registered (side 0), so there is no post-side plan; adaptation is limited to in-game choices

Why it scores here

The deck opens a functional plan reliably: the archetype core has about 98% chance of at least one copy in a 5-card opening hand, and 15 searchers give about 92% at least one searcher in hand, so the Ritual and Reptile engine is usually live by turn 2. Its conversion comes from Ritual Summoning Ame no Murakumo no Mitsurugi (a board wipe on Special Summon) and from Xyz/Link extenders, with Reptile recursion from the GY letting the deck rebuild after a disruption. Interaction density is high (Ash Blossom, Droll and Lock Bird, Maxx C, Ghost Ogre, Effect Veiler, Mitsurugi Great Purification), which supports a strong going-second position. Popularity and the archetype usage statistics confirm the list is the standard build but did not add points by themselves, and no card scores were averaged into the deck score. No recorded boards, no tournament record, and no side deck limit the confidence and keep Meta Power provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (weights not blended; Midrange profile used). Structural ≈ 65, Going First ≈ 64, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Banlist exposure (-1); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*64.9 + 0.20*60 = 63.9, then -3 modifiers = 61

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Archetype core and searcher density give high opening access (0.976 for the core in a 5-card hand)
• Multiple independent starters and Reptile recursion from the GY
• High hand-trap and negation density for going second
• Murakumo Ritual Summon gives a board-wiping closer

Weaknesses

• No side deck, so no post-side adaptability
• Low archetype exact-name purity; off-archetype Ryzeal, Branded and Mulcharmy cards dilute the core
• Several one-copy Limited cards and niche tech cards add brick risk
• Hand traps Droll and Maxx C are dead against some opening hands

Critical choke points

• Ritual Summon via Mitsurugi Ritual or Mirror: losing the Reptile tributes or the Ritual spell stops the Murakumo line
• Droll and Lock Bird as a one-card lock against the Mitsurugi search chain

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 within master-duel size rules; Limited and Semi-Limited copy counts are within the legal limit; Hypergeometric probabilities from the resolved list (0.976 core, 0.919 searcher)
• Observed: Usage statistics show the core cards (Saji, Kusanagi, Mitsurugi Prayers, Mitsurugi Mirror) at 100% inclusion
• Inferred: Opening access and brick estimates from composition and text; Going-second interaction density from text; Closing power read from ATK values and text
• Provisional: Meta Power (no dated metagame sample); Matchup coverage (no tournament data)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry; going-first, going-second and matchup rates are unknown Meta Power is Provisional without a dated metagame sample Only one guide mention (Vietnamese, no sections), low guide weight
