Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Ritual/Synchro/Link mechanics
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo no Mitsurugi (3200 ATK) or Ame no Habakiri no Mitsurugi (2400 ATK), backed by synchro and link extenders; Baronne de Fleur (3000 ATK) and Futsu no Mitama no Mitsurugi (2000 ATK / 3400 DEF) as recursive boards
• Turn 1 (going first): Search a Mitsurugi monster or Spell/Trap with Saji, Aramasa or Kusanagi, convert via Mitsurugi Ritual or a Yummy link/synchro line, and hold Ash Blossom, Infinite Impermanence or Droll as protection
• Turn 2 (going second): Use the 8 hand traps (Ash, Impermanence, Maxx C, Droll, Herald-style negation) to stop the opponent's first summon, then rebuild a Ritual board from the GY
• Recovery: Recycle Mitsurugi monsters and Spells from the GY through Saji, Kusanagi and Pre-Preparation of Rites, and use Mulcharmy draw effects to refill
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot change its configuration between games

Why it scores here

The deck reliably opens a functional plan: 14 searcher-text cards give about a 0.90 chance of at least one searcher in a 5-card opening hand, and the 98% archetype-core presence (21 core copies) means the list runs the standard Mitsurugi core. Conversion is credible but ritual-dependent: Mitsurugi Ritual plus four Ritual monsters and Saji/Kusanagi recursion turn into 2000 to 3200 ATK boards, with synchro and link extenders adding follow-up. Survival rests on eight hand traps and eight negate/removal effects, giving roughly a 0.76 chance of at least one hand trap in a 6-card going-second hand, though a single Droll or a graveyard banish plan is a documented weakness. No combo boards or tournament data exist, so the ceiling and floor are text-based inference, and the score comes from consistency, recovery and interaction on the system, not from the archetype's popularity or from averaging the card scores. The Yummy and Mulcharmy splash (about 22% exact-name purity) adds engine conflict, which is the main reason the score sits in the mid-50s.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.7, Going First ≈ 57, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Engine conflicts (Yummy/Mulcharmy/Sky Striker splash) (-2); Ritual choke point (-1); Unrecoverable choke point (Droll & Lock Bird) (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated meta sample)

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

• Dense searcher suite (14 searcher-text cards) gives high starter access
• Eight hand traps plus eight negate/removal effects give layered interaction
• Link and synchro extenders (9 Link, 6 Synchro) supply Extra-Deck flexibility
• Mitsurugi GY recursion regenerates resources after interruption

Weaknesses

• Low exact-name purity (21.8%) splits the engine across Yummy, Mulcharmy and Sky Striker
• Ritual pieces (Mitsurugi Ritual x2, Habakiri x2) are a narrow bottleneck
• No side deck means no post-side adjustment
• Guide reports vulnerability to a single Droll and to graveyard banish

Critical choke points

• Mitsurugi Ritual and its Ritual monsters
• Droll & Lock Bird as a single-card lock on the opponent's draw
