Mitsurugi Deck #765475 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon a Reptile boss (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) via Mitsurugi Ritual or Mitsurugi Mirror, or convert the board with Xyz bosses (Ryzeal Detonator, Number 38, Duo Drive).; Xyz pressure from Rank 4 and Rank 8 Xyz monsters built from Ryzeal and Reptile bodies, with Dragluxion and Hope Harbinger as late-game closers.
• Turn 1 (going first): Turn 1: search with Pre-Preparation of Rites, Mitsurugi no Mikoto (Saji/Aramasa/Kusanagi) or Mitsurugi Prayers to set up a Ritual Spell plus a Ritual Monster, then Ritual Summon a Reptile boss on turn 2 while holding Ash Blossom or Maxx C for interruption.
• Turn 2 (going second): Hold Droll & Lock Bird, Ash Blossom, Forbidden Droplet and Dominus Impulse to answer the opponent's board, then use the Ritual searcher chain to rebuild a Reptile boss the following turn.
• Recovery: Use Mitsurugi Great Purification and Mitsurugi Prayers to special summon Reptile monsters from the GY, and Mulcharmy draw effects to refill the hand once the field is empty.
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adjust between games in a best-of-3.

Why it scores here

The score is built from the deck as a system: a dense searcher layer (16 searcher-text cards, 93.5% chance of at least one in a 5-card opening hand) reliably finds a Ritual Spell and a Reptile Ritual boss, and the ritual boss then converts into board control or Xyz pressure. Interaction density is high for a 40-card main (hand traps, Forbidden Droplet, Dominus Impulse, Crossout Designator, and Ryzeal Detonator), which lifts end-board and going-second scores. The main penalties are the absence of a side deck (D12 is scored low and no post-side plan exists), the single Droll & Lock Bird and graveyard-banish exposure noted in the guide, and an exact-name archetype purity of only 25.5% across Ryzeal, Mulcharmy and other sub-archetypes. No combo boards were supplied, so the ceiling and median are text-based inferences, and no card scores were averaged into the deck score. Popularity (archetype core coverage of 99% by hypergeometric estimate) confirms the list is real and accessible but was not credited as power.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, with Toolbox adjustment weighting D7/D10 (none applied numerically). Structural ≈ 64.4, Going First ≈ 66, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: no_side_deck (-2); engine_conflict_archetype_purity (-2); banlist_exposure_limited (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*64.4 + 0.20*60 - 5 = 58.5, rounded to 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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 layer (16 searcher-text cards) makes the engine reliably live on turns 1 and 2
• Five hand traps plus Forbidden Droplet and Dominus Impulse give strong going-second interaction
• Ritual bosses (Murakumo 3200 ATK, Habakiri, Futsu) and Xyz closers (Detonator, Hope Harbinger, Dragluxion) give high end-board power
• Full Extra Deck with 13 Xyz and 2 Link gives flexible Rank 4 and Rank 8 options

Weaknesses

• No side deck, so no post-side plan in best-of-3
• Droll & Lock Bird (single copy) and graveyard-banish hate are known weaknesses per the guide
• Exact-name archetype purity is only 25.5%, with Ryzeal, Mulcharmy and generic cards diluting the engine
• Six Limited cards run at their limit, leaving no redundancy if one is removed
• No combo boards recorded, so floor, median and ceiling are text-only inferences

Critical choke points

• A single Mitsurugi Ritual or Mitsurugi Mirror is required for most boss lines; if the Ritual Spell is dead, the Ritual chain fails
• Droll & Lock Bird or Maxx C during the search chain can stall the draw engine for the turn
• Banish-based graveyard hate removes the recursion of Great Purification and Prayers

Recommended changes

Evidence & confidence

• Verified: Legal status for master-duel with 40 main, 15 extra, 0 side and no violations; All Limited and Semi-Limited copies are at or below their legal limit; Archetype purity exact-name 25.5%; Probabilities from hypergeometric draws over the resolved main deck
• Observed: Usage stats show Maxx C, Ash Blossom, Ame no Habakiri, Mitsurugi Prayers and Saji at 94-100% inclusion in the archetype
• Inferred: Engine consistency and brick rate estimates from searcher density and hand math; Going-first and going-second power from card text and interaction density; Median and ceiling output from text, since no combo boards exist
• Provisional: Meta power and matchup fit, pending a dated metagame sample; Tournament reliability relies on archetype context only
• 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 and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered
