• 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, can destroy all opposing monsters) or Futsu no Mitama no Mitsurugi via Mitsurugi Ritual, then convert the board with Extra Deck Synchro, Xyz and Link monsters; Extra Deck pressure from Psychic End Punisher, Super Starslayer TY-PHON and Enigmaster Packbit once a Synchro or Xyz line is established
• Turn 1 (going first): Pre-Preparation of Rites or a Reptile searcher (Aramasa, Lamia, Saji, Kusanagi) into Mitsurugi Ritual, Ritual Summon a Level 8 Reptile, then use Ash Blossom or Ghost Ogre to protect the line
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Maxx C or Dominus Impulse to stop the opponent's first board, then Ritual Summon through the interruption using the remaining Reptile tributes
• Recovery: Futsu no Mitama no Mitsurugi revives a Reptile from the GY, Mitsurugi Great Purification revives from the GY, and Mitsurugi Mirror or Magatama can Ritual Summon from the GY
• After siding: No Side Deck is registered, so there is no post-side plan in this list

Why it scores here

The deck reliably opens a Reptile searcher or Pre-Preparation of Rites in most hands (searcher text group about 0.94 in a 5-card opening hand), which makes the Mitsurugi Ritual line live early in most games. Conversion comes from Ritual Summoning Murakumo or Futsu, which gives a high-ATK board and, in Murakumo's case, a board wipe, and the Extra Deck then adds Synchro, Xyz and Link follow-up. Interaction is layered: six hand traps and about nine negation effects, including Ash Blossom and Ghost Ogre, cover the first disruption. The score is set by consistency, median output and interaction on the system as a whole. Archetype popularity earned no points, the deck has no tournament or win-rate data, and the card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: archetype purity (-2); banlist exposure (-1); ritual_choke_point (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*63.35 + 0.20*58 - 4 ≈ 58

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

• Searcher density gives a high chance of reaching the Ritual line
• Layered hand traps and negation cover the first disruption
• Murakumo and Futsu give high-ATK and board-wipe conversion
• Extra Deck covers Synchro, Xyz and Link, so the board can be extended after the Ritual Summon
• Legal list, with restricted cards within copy limits

Weaknesses

• Only one Ritual Spell path with 3 copies, so the starter is not guaranteed
• Off-archetype copies dilute the engine (30.9% exact-name purity)
• No Side Deck, so no post-side adaptation
• Guide notes vulnerability to Droll & Lock Bird and to banish-based GY removal
• No recorded boards, so the median and ceiling are inferred from text only

Critical choke points

• Mitsurugi Ritual (3 copies) plus Reptile tributes
• Double tribute from effects like Nibiru can cook the board, per the guide
• Droll & Lock Bird-style floodgates stop the searcher-based draw

Recommended changes

Evidence & confidence

• Verified: Legal main (40), Extra (15) and Side (0) counts for Master Duel; Restricted cards are within limits: Herald 1, Maxx C 1, Prayers 1, Habakiri 2; Card stats and text for all 40 Main Deck and 15 Extra Deck cards; Archetype purity 30.9% (17 exact Mitsurugi copies)
• Observed: Usage stats show Mitsurugi core cards at 100% inclusion (Maxx C, Saji, Prayers, Mirror)
• Inferred: Consistency from hypergeometric draw odds and searcher density; Interaction density from negation and removal text; Going-second hand-trap coverage at P ≈ 0.65
• Provisional: Meta Power and matchup fit, with no dated metagame sample; Post-side performance, since no Side Deck is registered
• 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 win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is Provisional unless a dated metagame sample is supplied guide is a single Vietnamese topic with no sections
