• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon Mitsurugi Ritual Monsters (Ame no Murakumo, Ame no Habakiri, Futsu no Mitama) with Mitsurugi Ritual or Mitsurugi Mirror, then press with the Ritual monsters and Xyz boss Ryzeal Detonator or Ryzeal Duo Drive; Xyz Summon Rank 4 and Rank 8 boss monsters (Light Dragon @Ignister, Eclipse Twins, Ryzeal Duo Drive, Ryzeal Detonator) once Ryzeal and Mitsurugi board presence is set up
• Turn 1 (going first): Normal Summon a Level 4 Reptile or Ryzeal starter (Mitsurugi no Mikoto Aramasa/Saji/Kusanagi or Ext Ryzeal), search a Mitsurugi piece with Pre-Preparation of Rites or Mitsurugi no Mikoto, and set up Ritual or Xyz follow-ups on the next turn
• Turn 2 (going second): Answer the opponent's board with Ash Blossom, Droll and Lock Bird, Maxx C or Mitsurugi Great Purification, then Ritual Summon or Xyz Summon through the remaining monsters (Inferred from card text)
• Recovery: Recur Mitsurugi monsters from the Graveyard with Futsu no Mitama no Mitsurugi and Mitsurugi Prayers, and rebuild a Ritual line from the Graveyard with Mitsurugi Ritual or Mitsurugi Mirror (Inferred)
• After siding: No side deck is run, so there is no post-side plan; the Main Deck is the only plan

Why it scores here

The deck reliably opens its Mitsurugi engine on the first turn: 22 core-archetype copies are in the Main Deck, with P(at least one in a 5-card opening hand) at about 0.99 by the proxy estimate, and a searcher density of 17 cards, which gives roughly 0.95 for at least one searcher (Inferred). It converts that opening into Ritual Summons of Ame no Murakumo and Ame no Habakiri, and then into Rank 4 and Rank 8 Xyz bosses, but no recorded boards exist, so the ceiling and median are text-only inferences. Interaction is layered across hand traps (Ash Blossom, Droll and Lock Bird, Maxx C), Mitsurugi Great Purification and Number 104, which gives moderate resilience, though the guide flags Droll and graveyard-banish decks as its main risks. The score comes from consistency, the combo ceiling and interaction taken on the deck as a system, not from averaging the card scores and not from Mitsurugi's popularity, and it is reduced for the five Limited or Semi-Limited copy restrictions and a deck with no side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (about 80/20 in the weighting). Structural ≈ 61, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*61 + 0.20*58 - 4 = 56

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Dense Mitsurugi core and searchers give a high chance of a functional opening
• Ritual and Xyz bosses reach high ATK and strong closing power
• Layered hand traps and negation give a defensive plan on the opponent's turn

Weaknesses

• No side deck means no post-side adaptation
• Five restricted cards leave little room for error on the banlist
• Off-archetype Extra Deck and Main Deck slots dilute the engine

Critical choke points

• Droll and Lock Bird on the going-first draw or the search chain shuts down most of the deck's search
• Graveyard-banish effects from opposing decks remove Ritual and recursion fuel
• Mitsurugi Ritual or Mitsurugi Mirror as the single Ritual enabler needs a Reptile in hand or on the field

Recommended changes

Evidence & confidence

• Verified: Legal status and copy limits for all restricted cards; Main Deck size 40 and Extra Deck size 15; Card stats and banlist status for each card; Core card inclusion and copy counts from usage statistics
• Observed: Core card inclusion statistics from the archetype usage data
• Inferred: Starter access probabilities from the hypergeometric estimates; Going-first and going-second plans from card text; Combo ceiling and interaction ratings from card text; Consistency, brick, and resilience reads
• Provisional: Meta Power and matchup fit, pending a dated metagame sample
• Data gaps: no combos supplied, so combo floor, median, and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry, so going-first, going-second, and matchup rates are unknown Meta Power is provisional unless a dated metagame sample is supplied the guide snippet is a single Vietnamese mention with no sections
