Identity & game plan
- Win condition: Extra Deck boss summons (Link and Xyz, e.g. Number 38, Super Starslayer TY-PHON, Divine Arsenal AA-ZEUS) backed by Mitsurugi ritual boards; Ritual monsters Ame no Murakumo no Mitsurugi (3200 ATK) and Futsu no Mitama no Mitsurugi (2000 ATK) via Mitsurugi Ritual and Mitsurugi Mirror
- Turn 1 (going first): Search a Mitsurugi or Ogdoadic piece with Mitsurugi no Mikoto monsters, Nauya and Mitsurugi Ritual, then ritual or link into a boss; hold Ash Blossom and Ghost Belle as interaction
- Turn 2 (going second): Respond to the opponent's board with Ash Blossom, Ghost Belle, Droll and Evenly Matched, then rebuild through Mulcharmy draw effects and Mitsurugi searchers
- Recovery: Mitsurugi and Ogdoadic monsters recur from the GY through Keurse, Ogdoadic Daybreak and Mitsurugi Great Purification; Mulcharmy draw effects refill the hand
- After siding: Not evaluable: no side deck is present in the export
Why it scores here
The list has no recorded boards, so the ceiling and median are text-only inferences and not observed output. Its consistency is moderate: about 61 percent of opening 5-card hands contain at least one of the 9-copy archetype core, and about 91 percent contain at least one searcher, but 14 of 29 distinct main-deck cards are singletons and 4 percent of the main deck is exact-name Alien. Interaction is the strongest part of the system, with 12 negation-text and 12 hand-trap cards across Ash Blossom, Ghost Belle, Droll and Evenly Matched, which supports going-second play. Extra Deck coverage is solid, with 15 slots filled by Link and Xyz bosses. The score is held down because five Forbidden cards and four over-limit cards make the list illegal, so it is capped and labeled theoretical/structural only. Popularity or archetype stats did not earn points, and no card scores were averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 42 | P(at least one of 9 core cards in opening 5) ~0.61; 3-copy starters ~0.25 each; searcher text ~0.91 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 38 | 12 hand traps and 18 tech cards in 55 main slots create dead-draw risk when Mitsurugi and Ogdoadic pieces are missing (Inferred) |
| D3 | Combo Conversion & Ceiling | 30 | No parseable boards; ceiling read from card text only (Ame no Murakumo, Number 38, Divine Arsenal) (Inferred) |
| D4 | Combo Floor & Median Output | 30 | No recorded median or power distribution; floor unknown (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 48 | Multiple searchers and two Mitsurugi tributable monsters give some redundant routes after a disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 40 | Ritual and GY recursion (Keurse, Daybreak, Great Purification) with draw-engine Mulcharmy; resource cost is not measured (Inferred) |
| D7 | End-Board & Interaction Quality | 58 | 12 negation-text cards plus Ash, Ghost Belle and Droll; banned Called by the Grave and Triple Tactics Talent removed (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 45 | Going-second hand-trap coverage ~0.79 for 12 hand traps (Inferred) |
| D9 | Offensive Pressure & Closing Power | 42 | Boss ATK up to 3200 (Ame no Murakumo) and 3000 (Number 38, Divine Arsenal), but the banned Number 41 and 60 are excluded (Verified/Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 30 | Off-archetype copies 67/71 of main; purity 4.3 percent; no side deck; efficiency low (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 55 | Extra Deck has 9 Link and 6 Xyz slots; Forbidden Number 41 and 60 are over the limit (Verified) |
| D12 | Side Deck Adaptability | 15 | No side deck exported; no post-side plan can be scored (Provisional) |
| D13 | Matchup Coverage & Format Fit | 35 | No tournament link and no dated meta sample; Meta Power is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Ritual chains, tribute decisions and multiple negation timings require careful sequencing (Inferred) |
How the score was computed
Strategy profile: Toolbox. Structural ≈ 41, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-8); engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then context modifiers -10; theoretical/structural-only because the list is Illegal
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.61 · 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
- Strong Extra Deck bosses and Link coverage
- Heavy negation and hand-trap density for going second
- Searchers give high redundancy in the opening hand
Weaknesses
- Illegal as built: five Forbidden cards and four copy-limit violations
- Mixed archetype engines with only 4 percent exact-name purity
- No side deck
Critical choke points
- Mitsurugi Ritual and the Ritual boss chain depend on a few Reptile tributes
- The banned Number 41 and 60 and Called by the Grave are removed from the list, so their roles need replacements
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Triple Tactics Talent, Called by the Grave, Number 41 and Number 60 (Forbidden) | Legal substitutes from the Mitsurugi or Ogdoadic core | Clears the Forbidden violations so the list can receive a normal score |
| 2 | Excess copies of Pre-Preparation of Rites, Mitsurugi Prayers, Droll and Ash Blossom | Single copies of the best Limited cards and one more searcher | Brings copy counts within legal limits and reduces brick risk |
| 3 | Off-archetype tech | Side deck of 15 cards | Adds post-side adaptability, which is currently absent |
Evidence & confidence
- Verified: Legality status Illegal with five Forbidden and four copy-limit violations; Main 55, Extra 15, Side 0 counts; Card text and stats for all listed cards; Archetype purity 4.3 percent
- Inferred: Hypergeometric consistency estimates (~0.61 core, ~0.91 searcher); Interaction and going-second read from negation and hand-trap text; Ritual and boss ceiling read from text only
- Provisional: Meta Power; Tournament reliability and matchup fit (no dated meta sample); Post-side plan (no side deck)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for this deck Meta Power is provisional unless a dated metagame sample is supplied No side deck in the export
