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

Identity & game plan

  • Win condition: Ritual Summon a Level 8 Reptile boss (Ame no Murakumo 3200 ATK, Ame no Habakiri 2400 ATK, Futsu no Mitama 2000 ATK) through Mitsurugi Ritual or Mitsurugi Mirror, then close with Xyz pressure; Rank 4 and Rank 8 Xyz boards (Ryzeal Detonator, Ryzeal Duo Drive, Galaxy-Eyes Photon Lord) built from Level 4 monsters
  • Turn 1 (going first): Search a Level 4 Reptile (Mitsunurugi Aramasa, Saji, or Kusanagi) and build toward Pre-Preparation of Rites or Mitsurugi Ritual, then Ritual Summon Murakumo or Habakiri by tributing Reptiles; keep Ash Blossom and Dominus Impulse for the opponent's turn
  • Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Dominus Impulse, Maxx C) to stop the opponent's first summon or search, then Ritual Summon from a Reptile search chain
  • Recovery: Revive Reptiles from the GY (Futsu no Mitama's effect, Mitsurugi Great Purification banish, Mitsurugi Prayers) and rebuild Level 4 Xyz material from the Ryzeal pieces
  • After siding: None: the deck runs 0 side cards, so there is no sided plan

Why it scores here

The score comes from how the whole list functions, not from averaging card strengths or from Mitsurugi's popularity. The searcher density (18 search-text cards, about 96% at least one in a 5-card hand) makes the Reptile engine reliably reachable, and a Level 8 Ritual boss on turn 2 gives the deck real ceiling. Interaction is the strongest dimension: six hand traps, about 11 negation-text cards and about 7 removal-text cards make the deck hard to stop once it survives the first turn. Its weak points pull the score down: the Ritual engine and the Ryzeal Xyz package use different resources, the Extra Deck of 15 spreads across several unrelated archetypes, and the deck has zero side cards. No combo boards or win-rate data exist, so the combo dimensions rest on card text and are labeled Inferred, and Meta Power stays provisional.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one searcher-text card in opening 5) = 0.96; P(at least one Pre-Preparation of Rites in opening 5) = 0.34, so the 3-copy starter is unreliable alone (Inferred).
D2 Opening-Hand Quality & Brick Management 55 13 singleton slots and mixed Ryzeal and Reptile pieces give some dead-card risk; the Ryzeal Level 4 pieces need an Xyz-material plan to function (Inferred).
D3 Combo Conversion & Ceiling 62 Level 8 Ritual bosses (Murakumo 3200, Habakiri 2400, Futsu 2000) give a high ceiling, but no recorded boards exist to measure conversion (Inferred from card text).
D4 Combo Floor & Median Output 48 No combos_evidence rows exist, so median output is unmeasured; the guide describes the deck as cheap and consistent (Observed guide, Inferred for the number).
D5 Interruption Resilience & Route Redundancy 60 Multiple Reptile searchers and GY revival give alternate lines after one interruption; Droll & Lock Bird and Ash Blossom add disruption pressure on the opponent (Inferred from text).
D6 Resource Economy, Recovery & Grind 62 Searchers and GY Reptile revival recycle resources, and Mulcharmy Fuwalos and Maxx C provide card flow (Inferred from card text).
D7 End-Board & Interaction Quality 78 Six hand traps, about 11 negation-text cards and about 7 removal-text cards give layered interaction (Verified card text, Inferred quality).
D8 Going-Second & Board-Breaking Power 74 Six hand traps cover the going-second turn and Murakumo's special-summon trigger can destroy all opposing monsters (Verified card text, Inferred board impact).
D9 Offensive Pressure & Closing Power 72 Several Level 8 Ritual bosses reach 2400 to 3200 ATK and Xyz bosses reach 2500 to 3000 ATK (Verified stat, Inferred closing).
D10 Main Deck Efficiency & Flexibility 62 40 main cards with 24 distinct entries, with some high-copy staples (3x Ryzeal, 3x Pre-Preparation, 3x Ash) and some one-of tech; some redundancy is missing (Inferred from composition).
D11 Extra Deck Efficiency & Coverage 45 15 Extra Deck cards cover at least 6 archetypes, and only about 3 cards (Ryzeal Duo Drive, Ryzeal Detonator, King of the Feral Imps) connect to the main engine (Verified composition, Inferred).
D12 Side Deck Adaptability 20 0 side cards in a format that allows up to 15, so no post-side adaptation exists (Verified legality, Inferred weight).
D13 Matchup Coverage & Format Fit 50 No tournament, meta-share, or dated sample is available, so matchup fit is Provisional and set to a neutral 50.
D14 Pilotability & Error Tolerance 62 The line requires multi-step Ritual tributes, Reptile target selection and Xyz material decisions; the guide calls the deck simple, so complexity is moderate (Inferred).

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 58, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflict (-3); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.96 · 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 package (18 search-text cards) makes the Reptile engine consistently reachable
  • Six hand traps plus about 11 negation-text cards give strong going-second interaction
  • Level 8 Ritual bosses and Xyz bosses reach 2400 to 3200 ATK
  • Cheap, with a strong ceiling for the cost (guide, Observed)

Weaknesses

  • Two engines compete: Ritual (Reptile tributes) and Ryzeal Xyz (Level 4 material)
  • Extra Deck of 15 spans about 6 archetypes, with low coherence
  • No side deck, so no matchup adjustment
  • Single-copy Level 8 Ritual boss access depends on Ritual spells (3 copies)

Critical choke points

  • Mitsurugi Ritual or Mitsurugi Mirror must be available to Ritual Summon the Level 8 bosses
  • Droll & Lock Bird can lock searches (guide, Observed), and the deck has no side answer
  • Banishing the GY removes the revival and Ritual monsters from the GY
Priority Remove Add Reason
1 Ext Ryzeal (1 copy, Limited) a second Mitsurugi Mirror (Reptile Ritual spell, Unlimited) Adds Reptile-compatible Ritual access without the non-Reptile Xyz cost; the deck already runs 5 Ritual monsters and 3 Ritual spells.
2 Eclipse Twins or Number 60 (off-plan Extra Deck) King of the Feral Imps (Reptile Xyz, already in the Extra list) Adds a Reptile Xyz that can search a Reptile, which matches the main engine (Inferred).
3 none a 10 to 15 card side deck A side deck gives a post-side plan; the format permits 0 to 15 side cards.

Evidence & confidence

  • Verified: Legal under BanMasterDuel: 40 main, 15 extra, 0 side (side 0 is within the 0-15 range); Limited and Semi-Limited copy limits are satisfied; Usage: Maxx C, Ame no Habakiri, Mitsurugi Prayers at 100%; Ash Blossom at 97.7%; Card text for Ritual monsters, searchers and hand traps
  • Observed: Guide: deck is cheap, Droll & Lock Bird is a major problem, and banish-based graveyard hate is a risk
  • Inferred: Hypergeometric consistency estimates; Dimension scores for D1 to D14; Structural and final scores; Engine conflict assessment
  • Provisional: Meta Power (no dated metagame sample); Matchup fit (D13)
  • Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot 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 deck title is null
