Mitsurugi Deck #765327 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual or Xyz Summon a Mitsurugi boss (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) or a Ryzeal Xyz, backed by hand-trap protection; Extra Deck pressure: Divine Golden Shadow Dragon Dragluxion, Ryzeal Detonator, Number 38, Divine Arsenal AA-ZEUS
• Turn 1 (going first): Turn 1: search with Mitsurugi Saji, Aramasa or Kusanagi (or Pre-Preparation of Rites / Bonfire for a Ritual Spell), then Ritual Summon a Mitsurugi boss via Mitsurugi Ritual or Mitsurugi Mirror; keep Ash Blossom / Maxx C for the opponent's first interaction
• Turn 2 (going second): Hold Droll & Lock Bird, Maxx C and Ash Blossom as the answer set; once the opponent's first Special Summon or search resolves, convert into a Ritual boss or Ryzeal Xyz line
• Recovery: Search again through Mitsurugi monsters and Ritual Spells (22 searcher-text cards); Mulcharmy Fuwalos and Seventh Ascension refill the hand after a broken turn; Mitsurugi Great Purification and Futsu no Mitama recur Reptiles from the GY
• After siding: None: the list runs 0 side cards, so there is no post-side plan in this build

Why it scores here

The deck opens reliably: the Mitsurugi core is in 23 copies, P(at least one core card in a 5-card opening hand) is about 0.99, and 22 searcher-text cards mean most hands can find a starter (Inferred). Its ceiling comes from Ritual bosses such as Ame no Murakumo (3200 ATK) and Dragluxion, backed by Ryzeal Extra Deck access. Interaction is layered across Ash Blossom, Droll & Lock Bird, Maxx C, Mitsurugi Great Purification, Crossout Designator and Ame no Murakumo's negate, which lets the deck survive a common disruption. Points were not earned from popularity or meta share, and no card scores were averaged into this result. The main limits are the lack of a side deck (0 cards), no recorded combo boards to confirm median output, and no dated meta sample, so Meta Power stays provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 57, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: no side deck (-2); Ritual tribute choke point (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 62.2, TR 58, modifiers -3 = 58

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

• Reliable starter density: core P ≈ 0.99 at hand 5 and 22 searcher-text cards
• Layered hand-trap and negate suite (Ash Blossom, Droll, Maxx C, Murakumo, Great Purification)
• Recursion via Reptile GY effects and Mulcharmy refill
• Extra Deck covers both Ritual bosses and Ryzeal Xyz lines

Weaknesses

• No side deck: no post-side adaptation
• No recorded combo boards, so floor and median output are unmeasured
• Vanity's Ruler and Mitsurugi Mirror are narrow cards that may brick
• Hybrid core: only 23.6% exact-name Mitsurugi purity

Critical choke points

• Ritual bosses need Reptile tributes; losing the Reptile board to a sweep stalls the Ritual line
• Droll & Lock Bird and Ash Blossom are the first answers, so an early Droll on the opponent's first search can cut the deck's search engine
