Identity & game plan

  • Win condition: Ritual Summon a Reptile boss (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) with Mitsurugi Ritual or Mitsurugi Mirror, then protect the board with Dominus and Mitsurugi traps; Link and Xyz finishers from the Extra Deck (Zealantis, TY-PHON, Gorgon, King of the Feral Imps) once the Reptile base is established
  • Turn 1 (going first): Pre-Preparation of Rites or a Saji/Aramasa/Kusanagi search, then Mitsurugi Ritual toward a boss while holding Ash Blossom and Maxx C for interaction
  • Turn 2 (going second): Hand-trap through the opponent's first Special Summon (Ash, Maxx C, Mulcharmy draw), then Dominus Impulse or Great Purification on the follow-up and Ritual or search into a boss
  • Recovery: Mitsurugi Great Purification and Futsu no Mitama no Mitsurugi revive Reptile monsters from the GY; Mulcharmy Fuwalos and Purulia refill the hand when the board is empty
  • After siding: No side deck is registered, so there is no evidence of a post-side plan; the deck has no sideboard adjustment path in this export

Why it scores here

The deck reliably opens a functional Mitsurugi plan: the 17 searcher-text cards give about 94% at least one searcher in a 5-card opening hand (Inferred), and the 22-copy Mitsurugi core is present in almost every opening. Conversion rests on Ritual Summoning Reptile bosses with Mitsurugi Ritual or Mirror, and the boss ceiling (Murakumo 3200 ATK, Habakiri 2400, Futsu 3400 DEF) is credited on text, not on recorded boards. Interaction is layered across Ash Blossom, Maxx C, three Dominus Impulse, two Dominus Spark, Great Purification and Magatama, so the deck can survive one interruption and recover from the GY. Points are earned for the system (searcher density, GY recursion, layered traps, Extra Deck coverage), not for the archetype's popularity: the guide and usage stats confirm the list is real, not that it is strong. The score is not an average of card scores. Missing sideboard (0 cards), no recorded boards, and no tournament link cap confidence at Medium.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 74 P(at least one searcher-text card in opening 5) = 0.94; P(at least one of 3 copies of a key card) = 0.32; 22-copy Mitsurugi core P(open at least one) = 0.98 (Inferred)
D2 Opening-Hand Quality & Brick Management 66 Four hand traps and 17 searchers reduce dead hands, but Reptile tribute chains and many zero-level spells/traps add brick risk; 4 hand-trap group P(at least one in going-second 6) = 0.47 (Inferred)
D3 Combo Conversion & Ceiling 58 No recorded boards; ceiling read from card text: Ritual bosses with board-wide destruction and -800 ATK on Habakiri, plus Link/Xyz finishers (Inferred from text)
D4 Combo Floor & Median Output 52 No combos_evidence rows; median output is inferred from search density and the guide's note that the deck is cheap and playable, not from measured boards (Inferred)
D5 Interruption Resilience & Route Redundancy 66 Ash, Maxx C, Fuwalos, Purulia, Great Purification revive and Futsu revive give independent recovery lines; no recorded interruption data (Inferred)
D6 Resource Economy, Recovery & Grind 70 Multiple searchers (Saji, Aramasa, Kusanagi, Wousu, Lamia) and GY revives regenerate resources; the guide flags Droll & Lock Bird as the main weakness to this economy (Inferred, with guide snippet)
D7 End-Board & Interaction Quality 70 Three Dominus Impulse, two Dominus Spark, Great Purification, Magatama and Ash/Maxx hand traps give layered interaction; negation and removal text in 10 and 13 cards (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 70 Murakumo on-summon destruction, Habakiri's -800 ATK and multiple negate traps challenge a going-second board; no going-second split is measured (Inferred)
D9 Offensive Pressure & Closing Power 72 Boss ATK (Murakumo 3200, Destruction 2800, TY-PHON 2900) closes games, but no end-board or conversion stats are recorded (Inferred from card stats)
D10 Main Deck Efficiency & Flexibility 60 42 main cards with 7 three-copy slots and 23 distinct cards; archetype purity is only 29.8% exact-name, with Dominus, Mulcharmy, Branded and Ecclesia spread (Inferred from composition)
D11 Extra Deck Efficiency & Coverage 58 15/15 Extra slots used across Link (8), Xyz (3), Fusion (3), Synchro (1); several Extra cards (Albion, Ecclesia, Destruction) need specific materials; usage stats show King of the Feral Imps and Dugares as core but absent (Verified stat, Inferred coverage)
D12 Side Deck Adaptability 25 Side deck is empty (0 of 15 slots used); no post-side plan can be evaluated (Verified count, Provisional score)
D13 Matchup Coverage & Format Fit 50 No tournament link or dated metagame sample; archetype meta-share absent, so matchup fit cannot be measured (Provisional)
D14 Pilotability & Error Tolerance 62 Multiple Ritual, tribute and search chains with several hand-trap timing decisions; step count moderate from card text (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 63, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Droll & Lock Bird exposure (-2); No side deck (-3); Limited / Semi-Limited exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural 63.4, TR 60, modifiers -5 gives 57.7 rounded to 58)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Searcher density (17 cards, about 94% at least one in opening 5, Inferred) keeps the engine live
  • Layered interaction: 4 hand traps, 3 Dominus Impulse, 2 Dominus Spark and Great Purification
  • GY recursion (Great Purification, Futsu no Mitama) and Mulcharmy draw give recovery after a clear
  • Legal list at the copy cap for every restricted card

Weaknesses

  • No side deck: no post-side plan
  • Low exact-name purity (29.8%) spreads the deck across Dominus, Mulcharmy, Branded and Ecclesia
  • Droll & Lock Bird is a single-card lock per the guide
  • Extra Deck has several cards whose materials are off-theme (Albion, Ecclesia, Destruction)

Critical choke points

  • Mitsurugi Ritual (3 copies) and the Reptile tribute base: losing the Ritual enabler or Reptile bodies stops the boss line
  • Droll & Lock Bird: a single copy on the field stops the search engine (guide note)
Priority Remove Add Reason
1 one off-theme Extra Deck card (for example Dyna Mondo or Reprodocus, which the usage stats do not show as core) a 15-card side deck with a Droll answer and a Dominus or Mitsurugi floodgate-style trap A side deck is the largest gap (D12 25) and the guide names Droll as the main threat; a side adds a post-side plan.
2 one Mulcharmy Purulia copy a Reptile-engine searcher or a second Mitsurugi Ritual route Reduces off-archetype copies and raises the Reptile tribute density the boss line depends on.

Evidence & confidence

  • Verified: Legal in Master Duel at 42 main, 15 extra, 0 side; all restricted cards at legal copy caps; Usage stats: Mitsurugi core inclusion 85 to 100 percent, 13 of 20 core cards present; Guide snippet notes the deck is cheap and that Droll is its main weakness
  • Inferred: Searcher, consistency and brick probabilities from the hypergeometric table; Interaction density from card text flags; Boss ceiling and recovery reads from card text
  • Provisional: Meta Power is null (no dated metagame sample); Matchup and format fit (D13 50) without tournament data; Post-side plan score (D12 25) with no side cards
  • 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 for going-first, going-second, matchup or brick rate Meta Power is provisional: no dated metagame sample No side deck in the export: post-side performance cannot be scored
