Mitsurugi Deck #773558 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo, Ame no Habakiri or Futsu no Mitama from Mitsurugi Ritual or Mitsurugi Mirror; Murakumo's on-summon effect destroys the opponent's monsters, then the Reptile attackers close.; Ryzeal Xyz line (Ryzeal Duo Drive, Ryzeal Detonator) fed by Ryzeal level-4 summons, with Rank 4 and Rank 8 Xyz finishers from the Extra Deck.
• Turn 1 (going first): Normal Summon a Mitsurugi no Mikoto to search a Mitsurugi Spell/Trap, set up Mitsurugi Ritual, then Ritual Summon a Level 8 Reptile using two Reptile level-4 tributes; Mulcharmy draw and Ice Ryzeal add redundancy.
• Turn 2 (going second): Hold a hand trap (Ash Blossom, Droll & Lock Bird, Maxx "C" or Nibiru) for the opponent's first search or summon, then run the same Mitsurugi Ritual route from a six-card hand.
• Recovery: Recover from the Graveyard: Mitsurugi no Mikoto and Mitsurugi Prayers add Mitsurugi cards back, Mitsurugi Great Purification can Special Summon a Reptile from the GY, Futsu no Mitama revives a Reptile, and Ryzeal Xyz can attach Ryzeal monsters from the GY.
• After siding: Not applicable: side deck is 0 cards in this Master Duel list, so there is no post-side plan.

Why it scores here

The deck reliably opens a functional plan: 17 searcher-text cards give about a 95% chance of at least one searcher in an opening five, and Mitsurugi Ritual and Mirror make the Reptile Ritual line reachable from one or two starters. Its conversion ceiling is high because Ame no Murakumo's summon effect clears the opponent's board, and Ryzeal Duo Drive and Detonator give a second Xyz-based route. Interaction and resilience are above average: 7 hand traps (about a 71% chance of one going second), 7 negation-text cards and 4 removal-text cards, plus Graveyard recursion through Mikoto, Prayers and Great Purification. The score comes from consistency, the two-engine structure and interaction across the system; it does not come from the Mitsurugi archetype's popularity or from averaging card scores. Points are held back by no side deck, dead slots (Seventh Tachyon works only with Number 104; the two Triple Tactics cards are conditional), and a three-copy Reptile tribute chain that is a single choke point. Combo evidence is absent, so the median and ceiling are text-based inference and confidence is Medium.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 65, Going First ≈ 67, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: banlist_exposure (-1); engine_conflict (-2); unrecoverable_choke_point (-2); low_construction_cost (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 dropped from Structural as meta-neutral and weights re-normalized over 97)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• 17 searcher-text cards make a starter very likely in the opening hand
• Two independent engines (Mitsurugi Ritual and Ryzeal Xyz) plus Mulcharmy draw give redundancy
• Seven hand traps give a strong going-second hit rate
• Murakumo's summon effect and Exciton Knight give board-breaking power
• Graveyard recursion (Mikoto, Prayers, Great Purification, Futsu) aids recovery
• Cheap construction according to the guide

Weaknesses

• Reptile tribute chain depends on three single-copy level-4 searchers
• Ryzeal summon restrictions conflict with Extra Deck summons
• Dead or conditional slots: Seventh Tachyon (works only with Number 104), two Triple Tactics cards, Ryzeal Plasma Hole
• No side deck, so no post-side adaptation
• Guide reports sensitivity to Droll and GY banish

Critical choke points

• Two Reptile level-4 pieces in hand or field are needed to fuel Mitsurugi Ritual
• Droll & Lock Bird (2 copies) can stop the searcher chain
• Double tribute effects such as Nibiru can end the Mitsurugi board (guide)

Recommended changes

Evidence & confidence

• Verified: Legality: Master Duel size and copy limits all pass; no Illegal status; Banlist statuses for the restricted cards; Card text excerpts for the resolved list; Usage-stat list and core-card count
• Inferred: Consistency estimates from hypergeometric draws; Starter and brick estimates; Combo ceiling and median from text only (no recorded boards); Interaction quality from semantic text reads; Guide statements about Droll sensitivity, GY banish risk and cost (single guide, qualitative)
• Provisional: Meta Power (null, no dated sample); D13 matchup and format fit (excluded from structural score); D12 post-side adaptability (no side deck and no post-side data)
• Data gaps: No recorded boards: 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 (going-first/second, matchup, brick/starter rates) Meta Power is provisional without a dated metagame sample Usage-stat join is inconsistent: Vallon, Number 104, King of the Feral Imps, Dugares the Timeless and Dyna Mondo appear in the resolved Extra Deck list but are flagged in_this_deck=false, so missing_core (66.7%) is unreliable Deck title is null; guide is one Vietnamese snippet with no sections
