• Secondary strategies: Toolbox, Ritual Engine, Xyz
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Ritual Summon Mitsurugi Reptile monsters (Ame no Murakumo no Mitsurugi 3200 ATK, which destroys all opponent monsters on Special Summon, and Ame no Habakiri no Mitsurugi 2400 ATK) using Mitsurugi Ritual or Mitsurugi Mirror, with Saji, Aramasa, Kusanagi, Wousu and Prayers searching the engine; Xyz pressure from Ryzeal Detonator, Ryzeal Duo Drive, Full Armored Utopic Ray Lancer and Galaxy-Eyes Photon Lord, fed by Ryzeal Xyz-enablers
• Turn 1 (going first): Opening searcher (Saji, Aramasa, Kusanagi, Pre-Preparation of Rites or Bonfire) into a Ritual Spell, then Ritual Summon Murakumo or Habakiri with Reptile tributes; hold Ash Blossom and Maxx C for the opponent's turn
• Turn 2 (going second): Hand trap first (Droll & Lock Bird, Ash Blossom, Maxx C, Dominus Impulse or Mulcharmy draw) to break the opponent's search or summon, then Ritual Summon through the open board
• Recovery: Search again from the deck with Mitsurugi monsters and Prayers, recurse Futsu no Mitama no Mitsurugi or Great Purification from the GY, and rebuild Ryzeal Xyz from GY-attached materials
• After siding: No side deck is registered (side_count 0), so there is no recorded post-side plan; the deck is locked into its main-deck configuration for every matchup

Why it scores here

The deck reliably opens a functional plan: 17 searcher cards in a 40-card main deck give an estimated 95% chance of at least one searcher in a 5-card opening hand (Inferred), and the Mitsurugi core is almost always present. It converts that plan into pressure through Ritual Summons of 2400-3200 ATK Reptiles, with Murakumo's board-wipe effect giving a real ceiling. It survives disruption through a dense hand-trap suite (Ash Blossom, Maxx C, Droll, Dominus Impulse, Great Purification, Crossout Designator) and recursion from the GY, while the 15-card Extra Deck of Xyz and one Link closes games. The score comes from consistency, interaction and closing power on the system, not from Mitsurugi being a popular archetype (no meta share was supplied) and not from averaging the individual card scores; it is held back by the absence of a side deck, the tech-heavy off-archetype slots, and the Droll and GY-banish sensitivity noted in the guide.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; Midrange profile used for the structural score. Structural ≈ 64, Going First ≈ 66, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: No side deck (-3); Off-archetype tech and mixed sub-archetypes (-2); Limited-status singletons (-1). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*64.26 + 0.20*58 - 6 = 57 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 17 searchers give near-certain engine access (0.949 at least one in 5 cards)
• Ritual Summons of Murakumo and Habakiri plus Reptile recursion give a real ceiling
• Dense interaction suite: Ash Blossom, Maxx C, Droll, Dominus Impulse, Great Purification, Crossout Designator
• Full 15-card Extra Deck with Xyz and Link closing options

Weaknesses

• No side deck: no post-side adaptability (side_count 0)
• Only 27.3% exact-name archetype purity; Ryzeal, Mulcharmy and Dominus slots split the engine
• Dependent on GY banishment and Droll-sensitive searches (guide notes)
• Off-theme cards such as Triple Tactics Talent, Forbidden Droplet and Seventh Tachyon are conditional

Critical choke points

• Reptile tribute fodder: Ritual Summon of Level 8 Ritual monsters needs enough Reptile monsters in hand or field
• Droll & Lock Bird or a GY-ban can stop Mitsurugi search chains mid-turn
• Ritual Spell access (4 copies) drives the Ritual line; no second independent route if they are removed

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel with 40 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copies within legal limits; Card text for Murakumo, Habakiri, Saji, Aramasa, Kusanagi, Wousu, Prayers, Dominus Impulse, Great Purification; Usage statistics show the Mitsurugi core (Saji, Kusanagi, Prayers, Great Purification, Pre-Preparation, Habakiri) at 100% inclusion
• Inferred: Searcher access 0.949 and core 0.998 from hypergeometric draw estimates; Midrange primary strategy and Toolbox secondary from composition and card text; Structural score 64 from the Midrange profile and the dimension scores; Murakumo board-wipe and Habakiri ATK reduction as the ceiling
• Provisional: Meta Power is null; no dated metagame sample supplied; Matchup fit (D13) and side adaptability (D12) cannot be measured without a tournament link or side data
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta share and per-pilot match record absent no side deck registered: post-side plan cannot be measured no win-rate telemetry exists in YGOVN for going-first, going-second or matchups Meta Power is provisional unless a dated metagame sample is supplied
