Mitsurugi Deck #766473 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, 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 (via Mitsurugi Ritual or Mitsurugi Mirror, tributing Reptiles) to swing the board, backed by Yummy and Link/Synchro pressure.; Yummy Level-2 Synchro Way monsters and Link-1 enablers recurring Yummy beaters and Yummy removal.
• Turn 1 (going first): Normal Summon a Level 1 Yummy monster (Cooky, Lollipo, Marshmao), search a Reptile via Saji, Aramasa or Kusanagi, then Ritual Summon Habakiri or Murakumo.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Droll and Maxx C for the opponent's first summon or search, then Ritual Summon Murakumo or Futsu to answer the resulting board.
• Recovery: Reuse Reptile tributes from the GY via Kusanagi and Futsu no Mitama's GY effect; Mulcharmy draws refill the hand once the field is empty.
• After siding: None: the deck runs 0 Side Deck cards and Master Duel is a single-game format, so there is no post-side plan.

Why it scores here

The deck reliably opens a functional starter: 14 searchers and a 0.90 chance of at least one searcher in a 5-card opening hand, plus a 0.98 chance of at least one archetype-core card (Inferred). Its two engines, Yummy Level-1 bodies and Mitsurugi Reptiles, feed Ritual Summons of Murakumo and Habakiri, which give it a high ceiling and a strong board-breaking effect on Special Summon. Eight hand traps and eight negation or removal effects make its interaction layered for both going first and going second, though the hand-trap density also creates dead cards on the play. Scoring rests on consistency and interaction across the whole system, and popularity or the Mitsurugi archetype's usage stats earned no points; card scores were not averaged. No recorded boards exist, so the median and ceiling are text-based inference, and Meta Power is left provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist_exposure (-2); engine_conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (no dated meta sample; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• 14 searchers and a 0.90 chance of at least one searcher in an opening hand of 5.
• Ritual Summon Murakumo and Habakiri give a high ceiling with board-wiping and ATK-reduction effects.
• Eight hand traps and eight negation or removal effects give layered interaction on either turn order.
• Two engines (Yummy and Mitsurugi) give redundant starters and multiple lines.

Weaknesses

• No Side Deck, so there is no adaptability beyond the main deck.
• Hand-trap density creates dead cards when going first.
• Off-archetype cards (Mulcharmy, Sky Striker) dilute the engine.
• No recorded boards, so the median output is unknown and the score carries high uncertainty.

Critical choke points

• Reptile tributes (Saji, Aramasa, Kusanagi) gate every Mitsurugi Ritual Summon.
• Droll and Lock Bird and Mitsurugi Prayers' LP cost are a sensitive point for the searcher density.

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side; 8 restricted cards within their legal copy limits.; Card text for all 40 Main and 15 Extra cards; archetype usage stats present (core present 70%).
• Inferred: Hypergeometric draw estimates: searcher 0.90, core 0.98, hand trap 0.76 going second.; Consistency, brick, and interaction reads derived from card text and role tags.
• Provisional: Matchup and format fit (D13) and Meta Power: no dated metagame sample or tournament link.
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference. No tournament link; archetype meta-share and per-pilot record absent. No win-rate telemetry (going-first/second, matchup, brick rate). Meta Power is provisional without a dated metagame sample.
