Legality

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

Identity & game plan

• Win condition: Ritual Summon Level 8 Reptile Ritual monsters (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) via Mitsurugi Ritual, Mirror or Magatama, then convert the 3200/2400 bodies and Xyz boards into attacks; Ryzeal Xyz (Duo Drive, Detonator) and Number 104/80 boards built from Level 4 monsters
• Turn 1 (going first): Search with Pre-Preparation of Rites or Mitsurugi no Mikoto (Aramasa/Saji/Kusanagi) to assemble Reptile tributes, then Ritual Summon a Level 8 Reptile; hold Ash Blossom and Droll for the opponent's first search
• Turn 2 (going second): Hold Droll & Lock Bird, Ash Blossom and Maxx C (about 65% chance of at least one hand trap in hand6) to slow the opponent's search, then Ritual Summon on the next turn
• Recovery: Reptile monsters in the GY can be recovered by Futsu no Mitama and the Mitsurugi search effects, and Pre-Preparation rebuys a Ritual Spell plus its monster
• After siding: No side deck supplied (Side Deck size 0); no post-side plan can be evaluated

Why it scores here

The deck is scored as a system, not as an average of its cards. It reliably reaches a starter: P(at least one of Mitsurugi Ritual, Pre-Preparation of Rites, Mitsurugi Mirror or Mitsurugi Magatama in opening hand of 5) is about 0.69, and P(at least one searcher in opening hand of 5) is about 0.95, so the Ritual engine is usually live by turn 2 (Inferred). Its conversion is strong on paper: Murakumo's Special Summon effect and Habakiri's ATK debuff give it a real board-breaking and closing ceiling, but no recorded boards exist, so the ceiling and median are text-based only. Interaction is dense (Ash Blossom, Droll & Lock Bird, Maxx C, Mitsurugi Great Purification, Light Dragon @Ignister, Ryzeal Detonator) and is the main reason the deck holds up through disruption, while its weakest point is Droll & Lock Bird (guide text also calls Droll the deck's main fear). Popularity did not earn points: the archetype core is present in almost every list, but that only confirms the list is real. No side deck is supplied and no tournament or meta sample exists, so Meta Power is provisional and the score excludes it.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62.5, Going First ≈ 62, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Banlist exposure (-2); Engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional): 0.80*62.5 + 0.20*58 = 61.6, then modifiers -4 = 57.6, rounded to 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ 0.1 · 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

• Ritual engine has 17 searcher-text cards and 2-for-1 Pre-Preparation, so starts are usually reachable (Inferred)
• Layered interaction: six hand traps, Great Purification, Habakiri debuff, Light Dragon destroy (Inferred from text)
• Murakumo gives a board-clearing Special Summon effect (Inferred from text)
• Legal in format with every restricted card at or under legal copies (Verified)

Weaknesses

• Droll & Lock Bird is a single-point weakness per the guide (Verified from guide snippet, translated)
• Side deck absent, so no post-side adaptation (Verified)
• Several Fusion extras (Garura, Flame Wingman, Mudragon, Dogma) lack partners in the list (Inferred)
• Low exact archetype purity (29.1%) with split engines (Verified)

Critical choke points

• Mitsurugi Ritual x3 / Pre-Preparation x3 as the main starter gateway (Inferred)
• Reptile tribute count for Level 8 Ritual monsters (Inferred from excerpts)

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 main, 15 extra, 0 side; all 8 restricted cards at or under legal copies; Archetype copy counts (Mitsurugi 16, Ryzeal 8, Mulcharmy 3); Hypergeometric probabilities from the probabilities block
• Inferred: Starter and searcher access estimates (D1); Hand-trap interaction density and going-second value (D7, D8); Fusion material gaps from excerpt text (D11)
• Provisional: Meta Power and D13 matchup fit (no dated meta sample); Side adaptability (no side deck)
• Data gaps: no combos supplied: combo floor/median/ceiling is text-only inference no tournament link: archetype meta-share and per-pilot record absent usage statistics in this deck flags conflict with the cards list: Dyna Mondo, Number 104, Vallon, Number 60 and King of the Feral Imps are listed in the Extra Deck here but marked in this deck=false, so usage-based presence is unreliable for Extra cards Fallen of Albaz and other Fusion partners are not in the list, so Fusion material gaps rely on excerpt text no win-rate telemetry; going-first/second and matchup rates unknown Meta Power is provisional
