Seventh Deck #765329 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Ryzeal Xyz pressure (Ryzeal Detonator, Ryzeal Duo Drive) backed by Mitsurugi ritual bosses (Ame no Murakumo, Ame no Habakiri) that clear or outclass the opposing board; Vanity's Ruler and Mulcharmy-driven card advantage if the board is stalled
• Turn 1 (going first): Open with Ice Ryzeal or a Reptile searcher, use Seventh Ascension or Pre-Preparation of Rites to find a ritual spell or Xyz enabler, and set Ash Blossom or Droll & Lock Bird for the opponent's first search
• Turn 2 (going second): Use the six-card hand to hold a hand trap (Ash, Droll, Maxx C) for the opponent's first non-hand-trap play, then rebuild through Mitsurugi searchers into a Ritual Summon of an 8-Level Reptile boss
• Recovery: Mulcharmy Fuwalos draw effects, Ext Ryzeal and Duo Drive recycling of Ryzeal monsters from the GY, and Mitsurugi searchers from Deck or banishment
• After siding: No side deck in Master Duel (side 0); there is no post-side plan to evaluate

Why it scores here

The deck reliably opens a searcher-driven start: 22 searcher-text cards give roughly a 0.99 chance of at least one in a 5-card opening hand (Inferred from the hypergeometric table), so it finds an engine most games. Its interaction is layered, with six hand traps (Ash Blossom x3, Droll & Lock Bird x2, Maxx C) plus Crossout Designator, Mitsurugi Great Purification, Node Ryzeal and Number 104 text, which lets it survive a single disruption and make a second-turn plan. Its closing power comes from two independent Extra Deck engines, Ryzeal Xyz on six Level 4 Ryzeal monsters and Mitsurugi ritual bosses at 2400 to 3200 ATK. The score is held down by the deck being a mix of three archetype families (exact Seventh purity 10.9%), by Seventh Tachyon having only one legal Extra target (Number 104), and by Pre-Preparation of Rites needing one of only two Ritual Spells. Popularity and archetype usage were not credited, and the score was not built from averaging card scores; there are no recorded boards and no meta sample, so the combo and meta reads are structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 54, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: engine conflicts (-4); banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional): 0.80*60 + 0.20*54 - 6 = 52.8, rounded to 53

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

• Searcher density (22 searcher-text cards) gives near-certain access to an engine in a 5-card opening hand (Inferred)
• Six hand traps plus Crossout, Great Purification, Node Ryzeal and Number 104 give layered interaction (verified card text, Inferred use)
• Two independent Extra Deck engines (Ryzeal Xyz on six Level 4 Ryzeal monsters; Mitsurugi ritual bosses on five Level 8 Reptile ritual monsters)

Weaknesses

• Three archetype families share one Main Deck (exact Seventh purity 10.9%), which dilutes engine coherence
• Seventh Tachyon x3 has only one legal Extra target (Number 104, one copy) and is a conditional dead card
• Pre-Preparation of Rites x3 needs a Ritual Spell, and only two are in the deck
• Vanity's Ruler cannot be Special Summoned and needs tribute, which conflicts with the Special Summon engines

Critical choke points

• The single Mitsurugi Ritual and single Mitsurugi Mirror are the only Ritual Spells, so losing one to disruption removes the ritual route
• Number 104 is the only legal target for Seventh Tachyon and the only Xyz negate in the Extra Deck
• Tribute fodder for ritual summons is four Level 4 Reptiles (Aramasa x2, Saji, Kusanagi)

Recommended changes

Evidence & confidence

• Verified: Legal status under BanMasterDuel: all 8 restricted cards within legal copies; Main 40 and Extra 15, with side 0, within Master Duel size rules; Copy histogram and Extra Deck breakdown from the list; Card text excerpts (Seventh Tachyon, Vanity's Ruler, Pre-Preparation, Ryzeal Detonator); Archetype usage stats: core cards at 100% inclusion
• Inferred: Hypergeometric opening-hand access and hand-trap odds; Searcher and brick reads from card text; Ryzeal Xyz and Mitsurugi ritual route read; Closing power from ATK values and effect text; Seventh Tachyon has one legal Extra target
• Provisional: Meta Power (no dated meta sample); Matchup coverage and format fit (D13); Side deck adaptability (D12): Master Duel has no side deck in this list
• 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, starter or brick rates); those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; the archetype label Seventh does not match the mixed Mitsurugi/Ryzeal/Seventh list
