SPYRAL Deck #773927 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 47/100 (±8 · Confidence: Medium)

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

Legality

Main 60 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link/Xyz bosses (K9-X "Werewolf" 3300 ATK, Underworld Goddess 3000 ATK, D/D/D Wave High King Caesar 2800 ATK) protected by a hand-trap and negation suite (Inferred); Vanquish Soul Caesar Valius, Sengenjin and Diabellstar beatdown once a board is established (Inferred)
• Turn 1 (going first): Open on a searcher to reach one archetype starter, then extend into a Link or Xyz boss; no verified combo steps exist, so this is structural (Inferred)
• Turn 2 (going second): Use hand traps (Infinite Impermanence, Ghost Ogre & Snow Rabbit, Maxx "C") and the Link/Xyz bosses to answer the first-turn board (Inferred)
• Recovery: Several searchers and graveyard revival effects (Fiendsmith's Requiem, Vanquish Soul summons, Sky Striker Ace monsters) allow starters to be rebuilt after disruption (Inferred)
• After siding: Not applicable: Master Duel runs without a sideboard, and the deck carries 0 side cards

Why it scores here

The deck is scored as a connected system, not as an average of its card scores. Its consistency comes from breadth rather than a single engine: 26 searcher-text cards give about a 95% chance of at least one searcher in an opening hand of five, but each individual starter reaches only roughly 16–23% per opening hand, and the deck is split across K9, Sky Striker, Vanquish Soul, Fiendsmith, Mikanko, Radiant Typhoon and other archetypes, with only 4 of 23 usage-core cards present and 3 SPYRAL-named copies in the Main Deck. Its strongest points are interaction and closing power: 18 removal-text cards, 6 negation-text cards, 5 hand traps and several high-ATK Link and Xyz bosses. No recorded boards exist, so combo floor, median and ceiling are not measured and are held near neutral. Popularity and archetype share did not earn points, and no dated meta or win-rate data was supplied, so Meta Power is provisional and the meta-neutral formula was used.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflicts (-5); engine compactness (-3); banlist exposure (-2); interaction breadth (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional; D13 dropped and weights re-normalized over the remaining 95 points: Structural = 5305/95 ≈ 55.8)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Broad searcher density (26 cards, P≥1 in opening hand ≈ 0.95)
• Interaction suite of five hand traps, 18 removal-text cards and 6 negation-text cards
• High-ATK Link and Xyz bosses with negation or removal text (K9-X Werewolf 3300, Underworld Goddess 3000)

Weaknesses

• No single coherent engine: 4% exact-name SPYRAL purity and 72 off-archetype copies
• Only 4 of 23 usage-core cards present, so the list does not run the archetype's standard core
• Low copy counts on the starters that anchor each engine (2 copies or fewer)
• No Side Deck, so no post-side adaptability

Critical choke points

• Each engine needs its own starter, and any one starter is present in only about 16–23% of opening hands
• Going second, five hand traps are only about 42% likely to produce a hit in the first six cards

Recommended changes

Evidence & confidence

• Verified: Main 60 / Extra 15 / Side 0 is legal under the Master Duel size rules (main 40–60, extra 0–15, side 0–15); Eight Limited or Semi-Limited cards, each run at or below its legal copy count; Card text and stats for every listed card; Composition: 51 distinct Main Deck cards, 72 off-archetype copies, 4% exact-name SPYRAL purity; Usage statistics: 4 of 23 core cards present (17.4%)
• Inferred: Engine consistency: hypergeometric P(≥1 searcher) ≈ 0.95 and per-starter ≈ 16–23%; Hand-trap going-second hit rate ≈ 0.42; Primary strategy Toolbox and secondary Midrange, from functional card roles and the absence of a single engine; Interaction and closing estimates from card text; Recovery and pilotability read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and tournament reliability (no tournament or match data); Side adaptability (no sideboard in Master Duel, neutral placeholder)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no sideboard, so D12 is a neutral placeholder rather than measured evidence guide evidence is a single Vietnamese-language SPYRAL guide snippet with no section structure
