Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Ritual Summon Reptile monsters (Ame no Murakumo no Mitsurugi 3200 ATK, Ame no Habakiri no Mitsurugi 2400 ATK, Futsu no Mitama no Mitsurugi) and convert them into Xyz / Ryzeal pressure such as Ryzeal Detonator (3000 ATK) and Ryzeal Duo Drive (2500 ATK).; Rank 4 and Rank 8 Xyz boards (Number 38, Number 104, Eclipse Twins, Dragluxion) that use Extra Deck summons and negation or removal effects to win board exchanges.
• Turn 1 (going first): Turn 1: Pre-Preparation of Rites or a Mitsurugi searcher (Saji, Aramasa, Kusanagi, Prayers) to find a Ritual Spell and a Ritual target, followed by Mitsurugi Ritual or Mirror into a Reptile Ritual Monster.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Maxx "C", Dominus Impulse or Mitsurugi Great Purification to answer the opponent's first board, then rebuild with a searched Mitsurugi monster and a Ritual Summon.
• Recovery: Recover from a single interruption by re-searching with Mitsurugi monsters and Pre-Preparation of Rites, and by returning Mitsurugi cards from the GY or banishment with Kusanagi, Prayers or Great Purification.
• After siding: Not applicable: the deck runs no Side Deck (side_count 0), so there is no post-side plan.

Why it scores here

The deck reliably opens a Mitsurugi starter: the archetype core (25 copies) gives about 99.5% odds of at least one piece in a 5-card opening hand (Inferred), and 15 searcher-text cards add redundancy, so the engine is live on turn 1 or 2 in most hands. Conversion runs through Reptile Ritual Monsters and Ryzeal/Xyz Extra Deck summons, but no combo boards were recorded, so ceiling and median are text-only inferences and are kept near the middle of the scale. Interaction is broad (6 hand-trap-tagged cards, negation text on Murakumo, Dominus Impulse, Great Purification, Number 38 and Number 104), which supports resilience and end-board quality. Scores are reduced for the lack of a side deck, Limited and Semi-Limited exposure (Droll & Lock Bird, Crossout Designator, Maxx "C"), and the Ryzeal Extra Deck summon restriction that conflicts with Mitsurugi lines. Popularity (the archetype is a common, accessible build) confirms the list is real but did not add points, and the score was built from consistency, interaction and closing power on the system, not by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65, Going First ≈ 68, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: banlist_exposure (-2); no_side_deck (-2); engine_conflicts (-1); engine_compactness (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated meta sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• Searcher density (15 searcher-text cards) makes the engine reliably live on turn 1 or 2
• Broad negation and removal across Murakumo, Detonator, Number 38, Number 104 and hand traps
• Compact Main Deck with three-copy staples and a flexible one-copy Extra Deck
• High closing power from 2400 to 3200 ATK Ritual monsters and 2500 to 3000 ATK Xyz monsters

Weaknesses

• No side deck, so no post-side adaptation
• Droll & Lock Bird and banish-based GY hate are described in the guide as the deck's main soft spots
• Multiple Limited cards mean the line depends on one copy each of several key pieces
• Ryzeal Extra Deck summon restrictions conflict with Mitsurugi turn sequencing

Critical choke points

• Ritual Spell plus a Reptile Ritual Monster in hand (Mitsurugi Ritual or Mirror with Murakumo, Habakiri or Futsu no Mitama)
• Hand traps held for the opponent's first board on going second

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main, 15 Extra, 0 Side within Master Duel size rules; Limited and Semi-Limited copy counts respected; Card text for Murakumo, Habakiri, Detonator, Droll & Lock Bird and Maxx "C" from the excerpts; Extra Deck composition: 12 Xyz, 3 Link, all single copies; Usage statistics show the archetype core (Maxx "C", Ash Blossom, Habakiri, Prayers, Kusanagi) is present
• Observed: Guide snippet (Vietnamese, one entry): the deck is cheap, searches strongly, is vulnerable to Droll and banish-based GY hate, and is viable with Xyz Rank 4 and 8
• Inferred: P(>=1 archetype core card in opening 5) = 0.995 from the hypergeometric table; Ceiling and median power estimated from card text alone; Interaction density and layering read from negation and removal text; Going-second hand-trap availability of about 65% in a 6-card hand
• Provisional: Meta Power (null), format fit (D13) and matchup coverage, because no dated meta sample or tournament link exists
• 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 are absent no win-rate telemetry exists in YGOVN for this deck usage_statistics in_this_deck flags conflict with the card list: King of the Feral Imps, Dyna Mondo, I:P Masquerena, S:P Little Knight and Number 60 are in the Extra Deck list with copies 1 but are flagged in_this_deck false, and listed as missing_core no side deck, so post-side plan and D12 are unverified Meta Power is provisional without a dated metagame sample
