Mitsurugi Deck #765126 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon a Reptile Ritual monster (Ame no Murakumo or Ame no Habakiri) with Mitsurugi Ritual or Mitsurugi Mirror, then convert board presence into Xyz pressure from Rank 4 and Rank 8 Xyz monsters (Ryzeal Detonator, Divine Golden Shadow Dragon Dragluxion) and Ryzeal Duo Drive.; Ryzeal Extra Deck Xyz pressure and Mulcharmy draw engine grinding the opponent through card advantage.
• Turn 1 (going first): Pre-Preparation of Rites or a Mitsurugi searcher (Saji, Aramasa, Kusanagi) into a Reptile tribute line, with Mulcharmy Fuwalos or Ice Ryzeal as board fillers and Ash Blossom and Droll as protection for the first Ritual.
• Turn 2 (going second): Hold Ash Blossom, Maxx C and Droll and Lock Bird to answer the opponent's first summon or search, then Ritual Summon or Xyz Summon into the open board.
• Recovery: Futsu no Mitama no Mitsurugi and Mitsurugi Great Purification recur Reptile monsters from the Graveyard, and Ryzeal Duo Drive and Ryzeal Detonator reuse Ryzeal materials from the Graveyard.
• After siding: None. The list runs no Side Deck (0 cards), and Master Duel ladder play is single-game, so there is no post-side adjustment.

Why it scores here

The deck reliably opens a Reptile ritual line: Mitsurugi Ritual (3 copies, about 34 percent in a 5-card opening hand) plus Pre-Preparation of Rites (3 copies) and several Reptile searchers give it a fairly accessible T1 engine, and archetype-core cards are almost always present (about 99 percent at least one in hand). Its interaction layer is the strongest part of the system: Ash Blossom, Maxx C, Droll and Lock Bird, Dominus Impulse, Forbidden Droplet and Mitsurugi Great Purification cover opponent summons, searches and activations, which supports going-second play. Conversion is credible on a Rank 4 and Rank 8 Xyz base, with Murakumo and Habakiri as board-breaking Ritual monsters, but there are no recorded boards, so the ceiling and median are text-based inferences. The main weaknesses are a low archetype purity (about 25 percent exact name, with 41 off-archetype copies), no Side Deck, and a documented vulnerability to Droll-style lock and graveyard banish; popularity and meta share were not credited, and the score was not built by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 64, Going First ≈ 61, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: banlist exposure (-1); unrecoverable choke point (-2); engine conflicts (-2); cheap and flexible positioning (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*63.66 + 0.20*60 - 4 = 58.9

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

• Layered interaction on opponent summons, searches and activations, including six hand-trap-capable cards
• Compact searcher density (16 searcher-text cards) supports consistent starts
• Rank 4 and Rank 8 Xyz coverage in the Extra Deck with several board-breaking Ritual monsters

Weaknesses

• Low archetype purity (about 25 percent exact name) and many off-archetype techs dilute engine cohesion
• No Side Deck, so there is no adaptation tool
• Ritual engine depends on Reptile cards in hand for tribute, which raises brick risk

Critical choke points

• Mitsurugi Ritual or Mitsurugi Mirror plus a Reptile Ritual monster in hand
• Droll and Lock Bird or graveyard banish disrupting the Pre-Preparation and Ritual route

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 are legal under master-duel size rules; Limited and Semi-Limited copy counts are within legal limits; Archetype purity 25.5 percent with 41 off-archetype copies
• Observed: Usage statistics show the Mitsurugi core cards (Maxx C, Ash Blossom, Habakiri, Mitsurugi Prayers) at 100 percent inclusion
• Inferred: Opening-hand starter probability from hypergeometric estimate (0.34 for 3-copy starter); Floor and ceiling from card text only, with no recorded boards; Going-second hand-trap coverage (0.58)
• Provisional: Matchup and format fit (no dated meta); Meta power (null)
• Data gaps: No recorded combos (total_combos 0): combo floor, median and ceiling are text-only inferences No tournament link: archetype meta share and per-pilot record absent Usage statistics flag King of the Feral Imps, Number 60, Dyna Mondo and I:P Masquerena as not in this deck, but the cards list places all four in the Extra Deck; the cards list was treated as the source of truth No post-side or Side Deck data; Master Duel ladder is single-game No win-rate telemetry exists in YGOVN for going-first, going-second, matchup or brick rates
