Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi 3200 ATK, Ame no Habakiri no Mitsurugi 2400 ATK, Futsu no Mitama no Mitsurugi 2000 ATK) via Mitsurugi Ritual and Mitsurugi Mirror, with Xyz boss backup (Ryzeal Detonator, Number 90 Galaxy-Eyes Photon Lord, Dragluxion).; Ryzeal Xyz line (Ice Ryzeal, Sword Ryzeal, Ext Ryzeal, Node Ryzeal into Ryzeal Duo Drive or Ryzeal Detonator) as a second engine when the Ritual line is blocked.
• Turn 1 (going first): Search a Mitsurugi monster or Ritual Spell (Mitsurugi no Mikoto searchers, Pre-Preparation of Rites, Bonfire, Mitsurugi Prayers), Normal Summon a Reptile, then Ritual Summon a Ritual boss with Mitsurugi Ritual or Mirror (Inferred from card text).
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C and Dominus Impulse to stop the opponent's first search or summon, then rebuild a Ritual boss from the hand and GY (Inferred from card text; no recorded boards).
• Recovery: Futsu no Mitama no Mitsurugi revives a Reptile from the GY when the opponent Special Summons; Mikoto Saji, Aramasa and Kusanagi re-search; Mitsurugi Great Purification can banish itself to revive a Reptile (Inferred from card text).
• After siding: Not applicable. Master Duel has no side deck and the evidence shows side_count 0, so there is no post-side plan to evaluate.

Why it scores here

The deck reliably opens a functional plan: the searcher-text group (17 copies) has about a 95% chance of at least one hit in a 5-card opening hand, and the archetype-core group (23 copies) about 99%. It converts that plan into pressure through Ritual bosses that hit 2000 to 3200 ATK plus Xyz backups at 2500 to 3000 ATK. It survives disruption well, with 5 hand traps, Crossout Designator, Forbidden Droplet and Mitsurugi Great Purification, and it recovers through GY revival and Mikoto re-search. Structural power is scored on the system (consistency, median output, interaction density), not by averaging card scores. Popularity and archetype usage confirm the list is real and accessible but added no points. No recorded boards, win rates or metagame exist, so the median, meta and matchup reads stay Inferred or Provisional and cap the score near the middle of the range.

Dimension scores

How the score was computed

Strategy profile: Combo profile; D13 weight dropped and remaining weights renormalized (meta-neutral). Structural ≈ 69, Going First ≈ 67, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 66. Modifiers: banlist_exposure (-2). Final formula: 0.80*Structural(69.5) + 0.20*TournamentReliability(66) + ContextModifiers(-2) = 66.8 -> 67 (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher density (17 searcher-text cards) gives reliable starts.
• Five hand traps plus several GY-or-field negates give strong going-second interaction.
• Two independent engines (Ritual and Ryzeal Xyz) cover each other's blocked lines.
• Cheap 40-card main with 15 Extra slots used fully; no dead Extra slots.

Weaknesses

• No recorded boards, so median output and realistic conversion cannot be confirmed.
• Banish-heavy graveyards and repeated Droll-style hand traps hit the GY-based recovery plan (guide evidence).
• Ritual tribute costs can strand a hand when no Reptile is present.
• Triple Tactics Talent and Dominus Impulse are conditional and can be dead early.

Critical choke points

• Mitsurugi Ritual or Mirror plus a Reptile in hand; without both the Ritual boss line stalls.
• Opponent banish-based GY hate removes the recursion pieces.

Evidence & confidence

• Verified: Legal status: 40 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copies within legal_copies.; Archetype Mitsurugi with 15 exact-name copies; Ryzeal 8 and Mulcharmy 4 support copies.; Usage stats: Maxx C, Mitsurugi no Mikoto Saji, Mitsurugi Prayers at 100% inclusion; Ash Blossom 97.8%.
• Observed: Guide snippet reports the deck is cheap and strong when searching but vulnerable to Droll and to banish-heavy GY decks.
• Inferred: Searcher-group opening probability ≈ 0.95 (hypergeometric).; Ritual boss conversion and T1 plan from card text.; Interaction density read from negate and removal text.; Consistency and brick estimates.
• Provisional: Meta Power null; no dated metagame sample.; Matchup fit (D13) dropped from structural score.; Tournament reliability estimate without tournament data.
• 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 provisional; no dated metagame sample. Deck title is null in the export.
