Legality

Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi, Ame no Habakiri no Mitsurugi) with Mitsurugi Ritual and push damage with their ATK, protected by hand traps and Ash Blossom / Ghost Ogre.; Xyz and Link follow-up from the Extra Deck (Galaxy-Eyes Photon Lord, King of the Feral Imps, Number 60 Dugares, Gorgon, Ragnaraika) once the Ritual board is established.
• Turn 1 (going first): Search a Mitsurugi monster or Ritual Spell with Mitsurugi no Mikoto Aramasa / Saji / Kusanagi / Lamia, then Ritual Summon a boss with Mitsurugi Ritual, keeping Ash Blossom or Ghost Ogre up against the opponent's first interaction.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Maxx C or Dominus Impulse for the opponent's turn-one interaction, then go to a Ritual boss or Mitsurugi Great Purification negation on the next turn.
• Recovery: Reuse Reptile monsters from the GY (Futsu no Mitama special summon, Mitsurugi Great Purification banish-and-summon) and re-search via Mitsurugi monsters to rebuild Ritual access after a board wipe.
• After siding: Not applicable: the list runs no Side Deck (Master Duel), so there is no post-side plan.

Why it scores here

The deck is scored as one Ritual system: 16 searcher-text cards and 3 Pre-Preparation of Rites / Ritual Spell pieces make a Mitsurugi starter likely in the opening hand (about 94% for at least one searcher, Inferred), and the core archetype group reaches about 98% for at least one copy. Interaction is layered across six hand traps, Dominus Impulse, Dominus Spark and Mitsurugi Great Purification, so the boss usually has a protected window. Two Ritual bosses (Ame no Murakumo no Mitsurugi, Futsu no Mitama) and the GY recursion give a credible ceiling, but no recorded boards exist, so the median and the ceiling are both text-based inference and not averaged card scores. Popularity (the Mitsurugi usage rows and the guide) confirms the list is real and accessible, but it did not add points; the guide's warning that Droll & Lock Bird and banish-heavy boards punish this deck was taken as a weakness. Engine coherence is only moderate: Mulcharmy requires controlling no cards while the Ritual engine needs cards, and the Dominus package is off-archetype.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 66, Going First ≈ 64, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: engine redundancy (2); banlist exposure (-1); engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 66.23 -> 0.80*66.23 + 0.20*62 = 65.38, plus context modifiers -1 = 64.38 -> 64

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered searcher density (16 searcher-text cards) gives high starter access
• Six hand traps plus Dominus Impulse, Dominus Spark and Great Purification give interaction on both turns
• Ritual bosses with 2000 to 3400 ATK and Murakumo's board-wipe effect give closing power
• Extra Deck covers rank 4 and rank 8 Xyz plus Link and Synchro options

Weaknesses

• No recorded boards, so combo conversion and median output cannot be measured
• No Side Deck, so there is no post-side adaptation
• Mulcharmy cards conflict with the Ritual engine's need for field cards
• Banish-heavy and Droll-style interaction is a known weakness per the guide

Critical choke points

• Mitsurugi Ritual plus one Ritual monster: losing both to a single banish or Droll-style lock stops the main Ritual line
• Dependence on tributing Reptile monsters: a single Herald or Limited-card board interaction can leave the Ritual engine without fodder

Evidence & confidence

• Verified: Legal under BanMasterDuel with 40 main, 15 extra and 0 side; Limited and Semi-Limited copy counts are within legal limits; Card text for the 22 distinct main-deck names and 15 Extra cards is present in the evidence
• Observed: Usage stats show Mitsurugi core cards at 100% inclusion (Maxx C, Saji, Mitsurugi Prayers)
• Inferred: Starter probability of about 0.98 for the core group and 0.94 for searchers; Interaction layering rated high from negation and removal text; Going-first and going-second splits estimated from the card text and hand-trap probability
• Provisional: Meta Power (null); D13 matchup fit; Tournament Reliability
• 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 for going-first, going-second, matchup or brick rates Meta Power is provisional unless a dated metagame sample is supplied Usage statistics mark S:P Little Knight, Number 60 Dugares, King of the Feral Imps and I:P Masquerena as not in this deck, but the card list contains all four in the Extra Deck; the missing_core result is unreliable for those cards Only one guide mention with no section structure
