Mitsurugi Deck #773563 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±6 · Confidence: Medium)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual or Xyz boss (Ame no Murakumo no Mitsurugi 3200 ATK, K9-X Werewolf 3300 ATK, Number 38, Arc Rebellion) reached through Mitsurugi searchers and the K9 Xyz route; K9 Xyz/Normal Summon pressure (K9-66a Jokul, K9-17 Izuna, K9-04 Noroi) backed by hand traps
• Turn 1 (going first): Normal Summon a Reptile or K9 searcher (Mitsurugi no Mikoto Aramasa/Saji/Kusanagi, K9-66a Jokul), search the Ritual Spell or Ritual Monster, and convert via Mitsurugi Ritual or Mitsurugi Mirror into a Ritual boss while holding Ash Blossom and Droll in hand
• Turn 2 (going second): Hold Ash Blossom, Maxx C and Droll & Lock Bird to answer the opponent's starter, then rebuild through Reptile GY recursion and a Ritual boss
• Recovery: Reptile monsters in the GY and banish zone are recoverable via Mitsurugi Prayers, Mitsurugi Great Purification and the Mikoto monsters' search effects; K9 Xyz monsters re-enter through K9-X Forced Release
• After siding: No side deck is registered, so no post-side plan can be evaluated; the main deck is the only plan

Why it scores here

The deck is a legal Master Duel Mitsurugi build whose 18 searcher effects and 24 archetype-core copies make a functional starter very likely in the opening hand (about 0.99 for at least one core card in 5, and 0.95 for at least one searcher), so the Structural engine score is driven by accessibility and recovery rather than by any recorded combo. Interaction is the strongest system trait: Ash Blossom, Droll, Maxx C, Ame no Murakumo, Great Purification, Number C104 and Number 38 cover negation, hand traps and board destruction across the duel. Ceiling and floor are scored separately: the Ritual and Xyz bosses give a high ceiling, but with no recorded boards the median is only inferred and held near the middle. Going second is weaker because single-copy starters are unlikely in a six-card hand, which is why the going-second read sits below going-first. Popularity and usage stats confirm the list is real and close to the archetype core (78.9% core present), but they did not raise the score, and card scores were not averaged into it.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (structural weights taken from the Midrange profile). Structural ≈ 63.6, Going First ≈ 66, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*63.6 + 0.20*58 - 2 = 60.5, rounded to 60

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

• Large searcher density (18) makes starters reliable on going first
• Two hand traps (Ash Blossom, Droll) plus Maxx C give layered interaction
• Boss range covers 3000+ ATK threats and board-destruction effects
• Compact 42-card main deck at the legal minimum

Weaknesses

• Only about 21% exact-name archetype purity: K9, Mitsurugi and Mulcharmy compete for slots
• Six Mulcharmy cards depend on the controls-no-cards condition and are conditional bricks
• No side deck, so no post-side plan
• Going-second single-copy starters are unlikely in a six-card hand

Critical choke points

• Mitsurugi Ritual and Mitsurugi Mirror (1 copy each) for the Ritual boss route
• Droll & Lock Bird: a guide notes the deck is strongly vulnerable to Droll
• Opponent banish of the GY, which the guide also flags as a risk

Recommended changes

Evidence & confidence

• Verified: Legal under master-duel size rules (42/15/0) with banlist entries Limited x3 and Semi-Limited x3 at legal copy counts; Card text for all 42 main and 15 Extra cards from the evidence pack; Usage stats: 15 of 19 core cards present (78.9%)
• Observed: The guide notes Droll and banish-GY vulnerability and the deck's low cost
• Inferred: Starter, brick and going-second probabilities from the hypergeometric table; All 14 dimension scores and the structural weighting; Ceiling and median reads from text (no combos recorded)
• Provisional: Meta Power (null) and D13 matchup fit (50) need a dated metagame sample
• Data gaps: Title is null on the Deck row No combos supplied, so 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 exists in YGOVN; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
