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

Legality

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

Identity & game plan

• Win condition: Ritual Summon Mitsurugi Ritual monsters (Ame no Murakumo no Mitsurugi sweeps the opponent's monsters on Special Summon; Ame no Habakiri no Mitsurugi gives -800 ATK to opposing monsters) and convert the board with Xyz and Link payoffs (Ryzeal Detonator, Ryzeal Duo Drive, Number 80, Dyna Mondo); Ryzeal Xyz pressure through Ext Ryzeal, Sword Ryzeal and Node Ryzeal recursion plus Number 104 / King of the Feral Imps card advantage
• Turn 1 (going first): Pre-Preparation of Rites or a Mitsurugi searcher (Aramasa, Saji, Kusanagi, Mitsurugi Prayers) into a Reptile Ritual Summon, backed by Ash Blossom and Droll on the opponent's turn
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird or Maxx "C" to slow the opponent's search, then rebuild through Mitsurugi Ritual and Mitsurugi Magatama's Ritual mode
• Recovery: Recover Reptile bodies and Ritual Monsters from the GY via Mitsurugi Great Purification, Futsu no Mitama no Mitsurugi and Ryzeal GY re-summons, then rebuild the Xyz board
• After siding: No side deck is registered (0 of up to 15 slots), so there is no defined post-side plan

Why it scores here

The deck reliably opens into its engine: 17 searcher-text cards give about a 95% chance of at least one searcher in an opening 5-card hand (Inferred, hypergeometric), and the 25-card archetype core is almost always present. Its conversion ceiling comes from the Ritual chain into Ame no Murakumo no Mitsurugi (a board-wipe on Special Summon) and Ame no Habakiri no Mitsurugi (-800 ATK to opposing monsters), followed by Rank 4 Xyz payoffs. Interaction is layered across six hand traps (Ash Blossom, Droll & Lock Bird, Maxx "C"), Great Purification, Ryzeal Detonator and Light Dragon @Ignister, which lifts the going-second score. Its weaknesses are a median that depends on having two Level-4 Reptile bodies on the field to pay Ritual costs, three Extra Deck cards that appear unsummonable from this list, and an empty side deck that leaves no post-side plan. No combo boards exist to measure median output, and the guide's claim that it is cheap was not scored, so popularity and archetype share earned no points; the score is the system's consistency, interaction and ceiling, not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 63, Going First ≈ 65, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-1); Dead Extra Deck slots / engine conflicts (-3); Unrecoverable Reptile choke point (-2); No post-side plan (-2); Engine compactness and redundant searchers (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Multiple searchers (17 searcher-text cards) make an opening searcher very likely
• Layered interaction: 6 hand traps, Great Purification, Detonator, Light Dragon, Masquerade
• High board-breaking ceiling via Murakumo and Habakiri
• Compact 40-card Main with a 25-card archetype core

Weaknesses

• Three Extra Deck cards appear unsummonable from this list
• No side deck means no post-side adaptation
• Droll & Lock Bird and GY banish hate are known pressure points per guide snippet
• Ritual Summon costs depend on two Level-4 Reptile bodies

Critical choke points

• Two Level-4 Reptile bodies on field for a Level-8 Ritual Summon
• Ame no Murakumo no Mitsurugi and Habakiri both require the Mitsurugi Ritual chain to resolve

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 40 Main, 15 Extra, 0 Side within limits; Copy limits respected for all Limited and Semi-Limited cards; Archetype purity 29.1% (16 of 55 Mitsurugi-name copies); One guide snippet cites Droll & Lock Bird and GY-banish as the deck's weaknesses
• Inferred: Opening-hand searcher probability ≈0.95; Hand-trap chance ≈0.65 going second; Three Extra Deck cards without valid materials; Ritual Summon requires two Level-4 Reptile bodies on the field
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck — post-side behaviour cannot be evaluated
