• Format: master-duel

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi, Ame no Habakiri no Mitsurugi, Futsu no Mitama no Mitsurugi) via Mitsurugi Ritual and Mitsurugi Mirror, backed by Extra Deck link, xyz, fusion and synchro threats.; Extra Deck pressure from Dark Magician of Destruction, Albion the Branded Dragon, Ecclesia and the Dark Dragon and Super Starslayer TY-PHON, plus Habakiri's -800 ATK effect on opposing monsters.
• Turn 1 (going first): Search a Mitsurugi piece (Pre-Preparation of Rites, Lamia, Mitsurugi no Mikoto Saji/Aramasa/Kusanagi, or Mitsurugi Prayers), tribute Reptile monsters into a ritual, and keep Ash Blossom and Maxx C for the opponent's turn.
• Turn 2 (going second): Use Ash Blossom, Maxx C and Dominus Impulse to slow the opponent's summons, then recover board through Reptile recursion (Futsu no Mitama, Mitsurugi Mirror) and a Murakumo or Habakiri ritual.
• Recovery: Re-enter Reptile monsters from the Graveyard through Futsu no Mitama no Mitsurugi and Mitsurugi Mirror, and refill the hand with searchers (17 searcher-text cards).
• After siding: Not applicable: the deck has no Side Deck (side count 0) and Master Duel is a single game with no sideboarding.

Why it scores here

The deck reliably opens its engine: 17 searcher-text cards give about a 94% chance of at least one searcher in a 5-card opening hand, and the archetype core gives about 98% access to some Mitsurugi piece (Inferred from hypergeometric estimates). It converts that access into large Reptile Ritual Summons (Murakumo 3200 ATK, Habakiri 2400 ATK, Futsu 2000/3400) and a 15-card Extra Deck with strong link and xyz threats, which earns the closing-power score. Interaction comes from four hand traps and multiple negate and removal texts, but the deck has no recorded boards, so combo ceiling and floor are text-based inference only and are scored low-confidence. Popularity and the archetype's usage data confirm the list is real and accessible, but they did not raise the score; the score comes from consistency, closing power and interaction on the whole system, and no card scores were averaged. The 40 off-archetype copies, including 5 Dominus and 5 Mulcharmy cards that need specific conditions, and the absence of a Side Deck hold the score down.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Combo as tiebreak; no reliable weight shift applied. Structural ≈ 63.8, Going First ≈ 66, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Unrecoverable choke point (-2); Off-archetype dilution (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*63.8 + 0.20*62 = 63.4, plus modifiers -3 = 60.4, rounded to 60

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• 17 searcher-text cards give about 94% searcher access in a 5-card opening hand (Inferred)
• Ritual bosses (Murakumo 3200 ATK, Habakiri 2400 ATK, Futsu 2000/3400) give strong closing power (Verified card stats)
• Four hand traps plus multiple negate texts give layered interaction (Inferred)
• Full, legal list with no violations and a legal Limited/Semi-Limited restricted-card count (Verified)

Weaknesses

• No recorded combo boards, so combo ceiling and floor are inferred from text only (Verified data gap)
• Exact-name purity 29.8%; 10 Dominus/Mulcharmy copies are conditional and dilute the engine (Verified)
• No Side Deck, so no post-side adaptation (Verified)
• Most of the archetype's core Extra cards (e.g. King of the Feral Imps, S:P Little Knight) are not run (Verified usage)

Critical choke points

• Mitsurugi Ritual and Mitsurugi Mirror are the gate to all Ritual bosses; each single copy is hard to find, though searchers mitigate this (Inferred)
• Droll & Lock Bird, per the Vietnamese guide, is a single-card problem for the deck (Provisional)
• Banish-heavy Graveyard strategies, per the guide, hamper Reptile recursion (Provisional)

Recommended changes

Evidence & confidence

• Verified: Deck is Legal for master-duel: 42 Main, 15 Extra, 0 Side; no violations; Restricted cards: Maxx C (1 Limited), Mitsurugi Prayers (1 Limited), Ame no Habakiri (2 Semi-Limited), The Fallen & The Virtuous (2 Semi-Limited); Exact-name purity 29.8%; off-archetype copies 40; Core-card presence 13 of 25 (52%)
• Observed: Usage: Mitsurugi archetype core cards appear in 100% of the sampled lists (usage statistics)
• Inferred: P(>=1 searcher in 5-card opening hand) 0.94 (hypergeometric); Interaction layers from hand trap and negate text (semantic read); Going-first and going-second estimates from hand-trap and starter probabilities
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link; Guide's claim that Droll & Lock Bird and banish-heavy Graveyards are the main threats
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates): these signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck (Master Duel is single-game); D12 cannot be measured from post-side data
