Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±10 · Confidence: Low)

• 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 boss monsters (Ame no Murakumo no Mitsurugi, Ame no Habakiri no Mitsurugi, Futsu no Mitama no Mitsurugi) through Mitsurugi Ritual and Mitsurugi Mirror; Rank 4 and Rank 8 Xyz boards (Ryzeal Detonator, Ryzeal Duo Drive, Gallant Granite, Dragluxion) plus Mulcharmy draw pressure
• Turn 1 (going first): Turn 1 search with Pre-Preparation of Rites, Bonfire or a Mitsurugi Reptile searcher to get the Ritual Spell and a Ritual Monster, then set up Tribute fodder from Reptile monsters
• Turn 2 (going second): Ash Blossom and Droll and Lock Bird as the first answer, then Ritual Summon a Mitsurugi boss; Maxx C and Nibiru are extra hand traps
• Recovery: Reptile and Mitsurugi monsters recycle from the GY (Futsu no Mitama no Mitsurugi, Mitsurugi no Mikoto Kusanagi, Mitsurugi Prayers) while Mulcharmy draw effects refill the hand
• After siding: Not applicable: the list runs 0 side deck cards (side rule allows 0-15) and Master Duel has no post-side step, so no post-side plan exists as built

Why it scores here

The deck reliably opens its plan: 17 searcher-text cards give a 0.95 chance of at least one searcher in a 5-card opening hand, and the 24-card archetype core is almost never absent (Inferred). Its conversion ceiling comes from Ritual Summoning Reptile bosses such as Murakumo and Habakiri, and from Xyz Rank 4 and 8 boards; no recorded boards exist, so the median is an Inferred read from card text and the guide note only. Interaction is dense for a Master Duel list (Ash Blossom, two Droll and Lock Bird, Maxx C, Nibiru, Great Purification, Plasma Hole, Murakumo's negation), which supports going-second play. Weaknesses are a split engine (only 23.6% exact-name purity across Mitsurugi, Ryzeal and Mulcharmy), a single-choke Droll exposure noted in the guide, and no side deck. Popularity and usage data confirm the list is real and accessible but earned no points on their own, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 64, Going First ≈ 62, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); unrecoverable choke point (-1); engine conflicts (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); (0.80*64.09 + 0.20*58) - 4 = 58.9, rounded to 59

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

• 17 searcher-text cards and 24 archetype-core copies make the opening hand reliably functional (Inferred)
• Seven hand traps and several negations give good going-second interaction (Inferred)
• Ritual boss and Xyz Rank 4 and 8 options give more than one closing route (Inferred)
• Extra Deck is fully used, with multiple Rank 4 and Rank 8 Xyz available (Verified)

Weaknesses

• Engine split across Mitsurugi, Ryzeal and Mulcharmy: only 23.6% exact-name purity (Verified)
• No side deck, so no adaptation between games and no post-side plan (Verified)
• Several Limited single copies (Maxx C, Prayers, Sword Ryzeal, Ext Ryzeal, Bonfire) make the list fragile to future list changes (Verified)
• Guide notes Droll and Lock Bird and graveyard banish as the main failure points (Observed in guide text)

Critical choke points

• Mitsurugi Ritual (2 copies) and Mitsurugi Mirror (1 copy) as the only Ritual access to the Reptile bosses (Inferred)
• Droll and Lock Bird stopping GY recursion after an early hand-add (Inferred)

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 matches the Master Duel size rule (main 40-60, extra 0-15, side 0-15); All restricted cards are at or below their legal copy limit (Maxx C 1, Prayers 1, Sword Ryzeal 1, Ext Ryzeal 1, Bonfire 1, Habakiri 2, Droll 2); Archetype exact-name purity is 23.6% (13 of 55 copies); Usage stats show 24 archetype rows and a core-present rate of 68.2%
• Observed: Guide (topic 1250) describes the deck as cheap and easy to pilot, weak to Droll and to graveyard banish, with Rank 4 and Rank 8 Xyz access
• Inferred: Searcher and archetype-core hand probabilities (hypergeometric, Main Deck only); Ceiling and median output from card text, since no recorded boards exist; Interaction density from hand-trap and negation text flags; Going-first and going-second split from hand-trap probability and card text
• Provisional: Meta Power (null) and D13 matchup fit: no dated metagame sample and no tournament link; D12 side adaptability: the deck has no side deck to evaluate
• 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; going-first, going-second and matchup rates are unknown usage statistics flags King of the Feral Imps, Number 60, Dyna Mondo, Number 104 and Vallon as in this deck=false, but the cards list includes them in the Extra Deck; core-card presence (68.2) may be understated and should be checked against the export Meta Power is provisional until a dated metagame sample is supplied
