Mitsurugi Deck #774370 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo no Mitsurugi or Ame no Habakiri no Mitsurugi off the Mitsurugi Ritual / Mitsurugi Mirror lines, then convert the board into Synchro, Link and Fusion beats (Psychic End Punisher, Juraishin, Enigmaster Packbit, Red-Eyes Dark Dragoon) (Inferred from card text); Extra Deck pressure from Link and Synchro monsters once the Mitsurugi board is established; Number 60 and Dyna Mondo support the Extra-Deck route (Inferred from card text)
• Turn 1 (going first): Pre-Preparation of Rites or a Mitsurugi searcher (Aramasa, Saji, Kusanagi, Wousu) for the Ritual spell and a Reptile Ritual monster, then Ritual Summon into a board-control or negate line (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Maxx C or Dominus Impulse for the opponent's first Special Summon or activation, then Ritual Summon with Mitsurugi Ritual or Mirror once the board is stable (Inferred)
• Recovery: Ritual monsters and Mitsurugi searchers re-fuel from the GY and banishment; Futsu no Mitama and Habakiri can re-summon Reptiles from the GY (Inferred from card text)
• After siding: Not applicable in Master Duel: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens its Mitsurugi engine: the archetype core (23 copies) gives a 99% chance of at least one core card in a 5-card opening hand, and 15 searchers give about 92%, which is why D1 is the strongest consistency read (Inferred, hypergeometric). Conversion is the ceiling, not the average: Ame no Murakumo and Habakiri are Ritual Summons that can wipe or shrink the opposing board, and the Extra Deck supplies high-ATK beaters. The median is much lower because the list runs 21 distinct Main Deck cards with 8 off-archetype copies (Mulcharmy and Dominus), no recorded boards exist, and the guide flags Droll & Lock Bird as a known bad matchup. Interaction is dense (7 hand-trap and 10 negation-text cards), and 71% of going-second six-card hands contain a hand trap (Inferred), but there is no Side Deck, so adaptation is weak. Popularity and archetype usage confirm the list is real and accessible, but they earned no points; the score comes from the consistency, ceiling and interaction of the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo primary; Midrange not blended into the weights. Structural ≈ 61, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Banlist exposure (-1); Engine conflicts from off-archetype cards (-2); Droll exposure (-2); Redundant interaction (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*61.3 + 0.20*56 - 3 = 57.2

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Archetype core and searchers are very likely to appear in the opening hand (Inferred)
• High ATK Ritual and Extra-Deck beaters give closing power (Verified stats)
• Multiple hand traps and negation effects give redundant answers, especially going second (Inferred)
• Multiple routes back from the GY through Ritual re-summons and Reptile recursion (Inferred)

Weaknesses

• No Side Deck, so there is no way to adapt after game one (Verified)
• Off-archetype copies (Mulcharmy, Dominus) dilute the engine and add bricks (Verified composition, Inferred impact)
• Weak against Droll & Lock Bird and banish-heavy boards according to the guide (Inferred from guide snippet)
• No recorded combo boards, so the median output cannot be measured (Verified gap)

Critical choke points

• Droll & Lock Bird, which the guide flags as a deck-stopper (Inferred from guide)
• The Ritual Summon line through Mitsurugi Ritual and Mirror, which needs Reptile tributes (Inferred from card text)

Evidence & confidence

• Verified: Legality: 40 Main, 15 Extra, 0 Side, all cards Unlimited or within legal copies; Archetype core present 13 of 19 with 68.4% presence in usage stats; Card text and stats taken from the evidence pack
• Observed: Usage statistics show Mitsurugi core cards at 100% and 98% inclusion rates
• Inferred: Consistency probabilities from the hypergeometric draw table; Ceiling and median reads from card text; Going-first and going-second plan descriptions
• Provisional: Meta Power is null and matchup fit is provisional because no dated metagame sample exists
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record are absent No win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is provisional without a dated metagame sample
