Identity & game plan

  • Win condition: Ritual or Xyz boss (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi, Ryzeal Detonator, Ryzeal Duo Drive) built from Mitsurugi Reptile tribute chains; Mulcharmy draw pressure and Ryzeal Xyz extension
  • Turn 1 (going first): Search a Mitsurugi or Ryzeal starter (Mitsurugi no Mikoto, Saji / Kusanagi / Aramasa, Sword or Ext Ryzeal) and pivot into a Ritual or Xyz boss; Mitsurugi Great Purification and Mitsurugi Mirror protect the line
  • Turn 2 (going second): Hand traps (Ash Blossom, Ghost Belle, Droll & Lock Bird, Nibiru) plus Ame no Murakumo's board wipe to break the opponent's board, then a Ritual or Xyz boss to close
  • Recovery: Mitsurugi and Ryzeal monsters recur from the GY through Ryzeal Cross, Mitsurugi Ritual and Futsu no Mitama's GY revival
  • After siding: No side deck (0 cards), so no post-side plan exists

Why it scores here

This OCG Mitsurugi list is scored as a connected system, not as an average of its card scores. Its Mitsurugi core (14 exact-name copies, P(at least one core card in a 5-card opener) of about 0.79) gives a reasonably accessible engine, and 24 searcher-text cards and 9 hand traps add redundancy and disruption. Conversion is the weak point: no recorded boards exist, so the ceiling and median are text-only inferences, and only 20% of the main deck is exact Mitsurugi, with the rest split across Ryzeal, Mulcharmy, Seventh, Forbidden and generic cards. The list has no side deck and no matchup or tournament data, so going-second adaptability and meta fit are provisional. Popularity (Mitsurugi usage stats) confirms the archetype is real but did not add points. The list is illegal (six copy-limit violations), so the score is capped as a structural-only theoretical read.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one Mitsurugi/Ryzeal starter in a 5-card opener) about 0.79 from the archetype core group; 2-card bootstrap plausible (Inferred)
D2 Opening-Hand Quality & Brick Management 55 24 searcher-text cards and 9 hand traps offset 15 tech and 4 trap-slot redundancies; no brick rate measured (Inferred)
D3 Combo Conversion & Ceiling 55 Ritual, Xyz and tribute chains reach strong bosses (Ame no Murakumo 3200 ATK, Ryzeal Detonator 3000 ATK), but no recorded boards exist (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards, so median output cannot be measured; expected floor is lower than the ceiling because many lines need specific Reptile tributes (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Hand traps and Ryzeal recursion give multiple routes after one disruption; Ash Blossom and Ghost Belle are real responses (Inferred)
D6 Resource Economy, Recovery & Grind 60 24 searcher-text cards and GY recursion (Ryzeal Cross, Mitsurugi Ritual, Futsu no Mitama) regenerate resources (Inferred)
D7 End-Board & Interaction Quality 60 Mitsurugi Great Purification, Ryzeal Detonator, Light Dragon @Ignister and Tornado Dragon give layered interaction (Verified text + Inferred)
D8 Going-Second & Board-Breaking Power 58 Ame no Murakumo's board wipe plus Evenly Matched, Nibiru and Great Purification challenge a going-second board (Inferred)
D9 Offensive Pressure & Closing Power 62 Several 2500-3200 ATK bosses (Ame no Murakumo, Ryzeal Detonator, Ryzeal Duo Drive, Dragluxion) close games (Verified stats)
D10 Main Deck Efficiency & Flexibility 45 54 main cards over 30 distinct names, 20.3% exact archetype purity, 23 Normal-type spells/traps and multiple off-archetype splashes lower compactness (Verified composition)
D11 Extra Deck Efficiency & Coverage 55 14 Xyz and 1 Link in the Extra Deck, with Ryzeal Duo Drive x2 as the most-used boss; flexible enough (Verified)
D12 Side Deck Adaptability 10 No side deck (0 cards), so there is no post-side adaptability (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament link, no dated metagame sample; archetype share unknown (Provisional)
D14 Pilotability & Error Tolerance 50 Multi-step tribute chains and Ritual/Xyz sequencing need many decision points, but recurring-searcher lines are learnable (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 56, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); engine conflict (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*54 + 0.20*45 - 10 = 42.2, then capped at 35 because the list is Illegal (structural-only, theoretical)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.79 · 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

  • Mitsurugi core is widely used (usage stats available), so the list is real and accessible
  • Dense searcher text (24 cards) and 9 hand traps give redundancy and disruption
  • Multiple 2500-3200 ATK Ritual and Xyz bosses close games

Weaknesses

  • Illegal: six copy-limit violations including three copies of Limited cards
  • No side deck, so no post-side adaptability
  • Low archetype purity (20.3%) and engine conflicts across Ryzeal, Mulcharmy and Seventh
  • No recorded boards, so combo conversion cannot be measured

Critical choke points

  • Mitsurugi Ritual / Mitsurugi Prayers tribute chains depend on a few Reptile monsters in hand or field
  • Ryzeal Detonator and Ryzeal Duo Drive depend on Ryzeal monsters reaching the GY, a single engine route
Priority Remove Add Reason
1 2 Mitsurugi Prayers, 2 Pre-Preparation of Rites, 2 Seventh Tachyon, 1 Ash Blossom & Joyous Spring, 1 Ice Ryzeal, 1 Sword Ryzeal (cut to legal copy limits) Legal-copy replacements from the same archetype core (e.g. another searcher or Mitsurugi starter) The list is illegal; fixing the copy limits is required before any normal score can apply
2 Off-archetype splash cards with weak engine fit (e.g. Night Sword Serpent, Nibiru) Additional Mitsurugi or Ryzeal starters Raises exact purity and reduces brick risk from conflicting Normal Summons
3 None (side deck absent) A 10-15 card side deck with Ash Blossom, Droll & Lock Bird and anti-Xyz or anti-Ritual cards Provides post-side plans for best-of-3 play

Evidence & confidence

  • Verified: Illegal status: six copy-limit violations (legality block); Main 54 / Extra 15 / Side 0 sizes; Archetype purity 20.3% and copy histogram; Banlist statuses of Limited and Semi-Limited cards
  • Observed: Usage stats: Mitsurugi Great Purification 86.8%, Mitsurugi Mirror 81.6%, Mitsurugi no Mikoto Kusanagi 79.8% inclusion
  • Inferred: Starter access about 0.79 (hypergeometric); Brick and interaction ratings from card text; Going-first and going-second estimates
  • Provisional: Meta power (no dated metagame sample); Matchup and format fit (no tournament link)
  • Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchups or brick rate Meta power is provisional without a dated metagame sample No side deck, so post-side plan is absent
