• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Ritual Summon a Mitsurugi boss (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) via Mitsurugi Ritual/Mirror, or Xyz-summon a large boss from K9/Mitsurugi material; K9 Xyz and Normal Summon pressure (K9-66X Jacks, K9-17 Ripper, K9-66a/b) backed by Mulcharmy draw
• Turn 1 (going first): Search a Mitsurugi/K9 engine piece (Mitsurugi no Mikoto searchers, A Case for K9, K9 Normal Summons when the opponent holds 2+ cards), then set up a ritual or Xyz boss while holding Ash Blossom and Droll as protection
• Turn 2 (going second): Open with Ash Blossom or Droll (Semi-Limited, 2 copies) to stop the first search, then rebuild through Mulcharmy draws and a ritual or Xyz follow-up
• Recovery: Multiple independent searchers (Mitsurugi no Mikoto Saji/Aramasa/Kusanagi, Pre-Preparation of Rites, Habakiri) and Graveyard Ritual revival (Mitsurugi Prayers, Mitsurugi Mirror) allow rebuilding after a single interruption
• After siding: Not applicable: the deck runs 0 Side Deck cards, so there is no post-side plan

Why it scores here

The deck scores as a connected Mitsurugi ritual/search system, not as an average of its card scores. Searchers are dense (18 searcher-text cards; P(at least one searcher in a 5-card opening hand) ≈ 0.96), so the engine is usually live by turn 2, and the core archetype group is almost always drawn (P ≈ 0.987). Interaction is layered across six hand traps and several negate or removal effects, which gives it a credible going-second plan through Ash Blossom and Droll. The ceiling is capped by the absence of any recorded boards, so the combo ceiling and median are inferred from card text only, and the deck's 20% exact-archetype purity with K9 and Mulcharmy splash lowers engine coherence. Popularity and archetype usage confirm the list is real but do not by themselves raise the score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63.4, Going First ≈ 64, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Banlist exposure (-2); Engine conflicts / split engines (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional/null; Structural 63.4 → 50.72, TR 58 → 11.6, modifiers −4 → 58.3, rounded to 58)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher text (18 cards) makes the engine reliably live (P ≈ 0.96 in 5 cards)
• Six hand traps plus Maxx C and Droll give strong going-second interaction
• Ritual and Xyz bosses reach 2400–3200 ATK with negate or destroy effects

Weaknesses

• No side deck, so no post-side adaptation
• No recorded boards, so the combo ceiling and median are inferred only
• Split engines (K9, Mitsurugi, Mulcharmy) with 20% exact-archetype purity

Critical choke points

• Droll & Lock Bird (2 copies) can stall the search engine and K9 Normal Summons for the whole turn
• Ritual Summon requires a Ritual Monster in hand plus Mitsurugi Ritual or Mirror; losing both shuts the Mitsurugi line

Recommended changes

Evidence & confidence

• Verified: Legal list: 40 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copies within legal max; Card text and stats for all 40 Main and 15 Extra cards; Usage stats: Mitsurugi core cards at 84–100% inclusion
• Observed: No measured boards; combo evidence absent
• Inferred: Engine live probability (hypergeometric) and brick estimate; Going-first and going-second strength read from text and interaction count; Ceiling and median combo output read from card text
• Provisional: Meta Power (null) and matchup fit (D13)
• 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 No win-rate telemetry (going-first, going-second, matchup, brick and OTK rates) Meta Power is Provisional without a dated metagame sample No Side Deck, so D12 has no performance basis
