• 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 Ame no Habakiri no Mitsurugi, or Extra Deck beaters such as Majesty's Fiend, Vanity's Fiend, Dragluxion and Umbral Horror Masquerade; Fiendsmith Lacrima and Charmer Quartet in Bloom pressure, with Yummy monsters as cheap Link-1 and Synchro-enabled bodies
• Turn 1 (going first): Mitsurugi Prayers or Piri Reis Map to search a Mitsurugi/Fiendsmith monster, Yummy lines from hand via a Link-1 monster, and Ash Blossom or Droll held up as protection
• Turn 2 (going second): Hand traps (Ash Blossom x3, Droll & Lock Bird x2, Maxx C) plus Jinzo and Spell Canceller to strip the opponent's board, then Ritual or Synchro conversion on the following turn
• Recovery: Saji and Kusanagi recover themselves and other Mitsurugi cards from the GY, Fiendsmith monsters recur from the GY, and Mulcharmy draw effects refill the hand once the field is empty
• After siding: None: the deck runs no Side Deck cards, so there is no evidenced post-side plan

Why it scores here

The deck scores as a system rather than as an average of its cards. It reliably reaches functional boards through six hand-traps and several searchers (Piri Reis Map, Mitsurugi Saji, Kusanagi, Fiendsmith Engraver, Lacrima), which earns the resilience and resource-economy dimensions. Conversion is the weak link: the Ritual engine rests on only two Ritual monsters and a few Reptile tributes, and there are no recorded boards to show a median output. Interaction is broad (Ash Blossom, Droll x2, Maxx C, Jinzo, Spell Canceller, Umbral Horror Masquerade) and closing power comes from several 2400 to 3200 ATK bodies. Consistency and efficiency are held back by the mix of four archetypes (only 7 exact Mitsurugi copies) and by the absence of any Side Deck, so the score is not raised by the archetype's popularity or by the guide's description of it as cheap.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 58, Going First ≈ 57, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflicts (-3); banlist exposure (-1); no side deck (-2); searcher density (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*58 + 0.20*55 = 57.4, plus modifiers -5 = 52.4, rounded to 52

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Six hand-traps and two Droll-style disruptions give the deck resilience on the going-second turn
• Fourteen searcher-text cards keep the hand supplied across turns
• Broad interaction: Jinzo, Spell Canceller, Umbral Horror Masquerade, Herald
• Several high-ATK closing bodies (Murakumo 3200, Dragluxion 2500, Masquerade 3000)

Weaknesses

• Off-archetype mix: only 7 exact Mitsurugi copies, with Yummy, Fiendsmith and Mulcharmy taking most slots
• Ritual engine rests on two Ritual monsters and a few Reptile tributes, a thin conversion route
• Zero Side Deck cards, so no post-side adaptability
• Guide notes the deck is vulnerable to Droll & Lock Bird, a single common disruption

Critical choke points

• Droll & Lock Bird on the first search or Normal Summon halts the searcher chain
• Reptile tribute requirement for both Ritual monsters, which depends on a small Reptile count
• Two Ritual monsters only: losing Mitsurugi Ritual or Mirror shuts off the top-end finisher

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side within size rules; Copy counts and banlist status for each restricted card; Archetype purity of 12.7% from composition; Card stats and text excerpts for every listed card
• Observed: Guide snippet notes the deck is cheap and that Droll is a main vulnerability
• Inferred: Brick and consistency reads from the hypergeometric probabilities and the copy histogram; Interaction quality and closing power read from card text; Going-first and going-second estimates
• Provisional: Meta Power (null) and matchup fit, pending a dated metagame sample; Median output, pending recorded boards
• 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 in the export
