Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±8 · 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 and Xyz boss monsters: Ame no Murakumo no Mitsurugi (3200 ATK, destroys opposing monsters on Special Summon), Ryzeal Detonator (3000 ATK) and Ryzeal Duo Drive (2500 ATK) (Inferred from card text); Ame no Habakiri no Mitsurugi (2400 ATK ritual, -800 ATK to opposing monsters) and Divine Golden Shadow Dragon Dragluxion / Number 38 (Inferred from card text)
• Turn 1 (going first): Search a Mitsurugi or Ryzeal starter with Mitsurugi no Mikoto Saji/Aramasa/Kusanagi, Pre-Preparation of Rites or Bonfire, then extend into a Rank 4 Xyz or Ritual boss while holding Ash Blossom and Droll for the opponent's response (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C or Dominus Impulse to stop the opponent's first Special Summon or search, then rebuild a Ritual or Xyz boss from the GY and hand (Inferred)
• Recovery: Mitsurugi searchers and Pre-Preparation of Rites refill the hand; Saji, Aramasa and Kusanagi can add back from the GY or banish; Futsu no Mitama can Special Summon a Reptile from the GY (Inferred)
• After siding: Not applicable: the deck runs no Side Deck (side_count 0), so there is no post-side plan (Provisional)

Why it scores here

The deck reliably opens a functional plan: 15 searcher-text cards and 25 archetype-core copies give a hypergeometric P(at least one core card in a 5-card opening hand) of about 0.995, and the 3-copy Ice Ryzeal, Pre-Preparation of Rites and Mulcharmy give redundant starters (Inferred). It converts that plan into pressure through three Rank 4 and 8 Xyz and Ritual finishers with 2400 to 3200 ATK. Interaction is dense, with 6 hand traps (P(at least one in a 6-card going-second hand) about 0.65), Ash Blossom and Droll x2 covering the opponent's first play, and negation text on several boss monsters, so it survives a single interruption. The score rests on consistency, median output and interaction on the whole system, not on averaging card scores; Mitsurugi's popularity and the single guide's endorsement did not earn points. Deductions: no side deck, no recorded boards, three loosely linked sub-engines (exact archetype purity 21.8%), and reliance on Droll & Lock Bird, a Semi-Limited card, as a fragile choke point.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 68, Going First ≈ 73, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: banlist exposure (-2); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*67.8 + 0.20*62 = 66.6, then -4 modifiers = 63)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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 and starter redundancy, with 25 archetype-core copies and P(core in opening 5) about 0.995
• Six hand traps and multiple negations covering both turn orders
• High-ATK Ritual and Xyz finishers with a board-wipe Murakumo
• Compact 40-card main with redundant 3-copy engine pieces

Weaknesses

• No side deck, so no post-side adaptation
• Heavy reliance on two Semi-Limited Droll & Lock Bird copies as the key hand trap
• Three loosely linked sub-engines and low exact archetype purity
• Multi-step Ritual and Ryzeal lines raise the pilot burden

Critical choke points

• Droll & Lock Bird banned or limited would reduce going-second protection and searcher consistency
• Mitsurugi searchers depend on Reptile monsters in hand or field to tribute and continue the line

Recommended changes

Evidence & confidence

• Verified: Legality: 40 main, 15 extra, 0 side within master-duel size rules; all restricted cards at legal copies; Card text and stats for all 40 main and 15 Extra cards; Archetype usage stats: 22 rows, 15 of 20 core cards present
• Observed: Guide snippet: the deck is cheap and fears Droll; mass Special Summon triggers and banish-heavy boards are risks
• Inferred: Hypergeometric consistency estimates (searcher, core and hand-trap groups); Ceiling and closing power read from card text; Going-first and going-second plans and choke point analysis; Pilotability estimate
• Provisional: Meta Power is null: no dated metagame sample; Matchup and format fit (D13) and side deck adaptability (D12)
• Data gaps: no combos supplied; 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 unless a dated metagame sample is supplied deck has no side deck, so post-side performance cannot be assessed only one guide with a single Vietnamese snippet; no section titles
