SPYRAL Deck #773590 — Yu-Gi-Oh! Master Duel

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 46 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link, Fusion and Xyz boss monsters (SPYRAL Sleeper 2800, Galaxy-Eyes Photon Lord, The Zombie Vampire, Dragunity Lord - Georgius, Imsety 3000) that are fed by SPYRAL recursion from the Graveyard (Inferred from card text); Horus monsters Special Summoned from the GY once King's Sarcophagus is on the field (Inferred from card text)
• Turn 1 (going first): Use SPYRAL searchers (Quik-Fix, Master Plan, Mission, Super Agent) to convert the opening hand into a Link or Fusion boss while holding Ash Blossom / Droll / Maxx C as protection (Inferred)
• Turn 2 (going second): Hold Droll & Lock Bird, Ash Blossom, Maxx C and Infinite Impermanence to answer the opponent's first board, then rebuild with SPYRAL GY recursion (Inferred)
• Recovery: Recover from disruption by Special Summoning SPYRAL monsters from the GY (Quik-Fix, Sleeper by banishing 3 SPYRAL, Big Red) and re-searching with Master Plan and Mission (Inferred)
• After siding: Master Duel has no sideboard; side_count is 0 and no post-side plan applies.

Why it scores here

The deck reliably opens into its SPYRAL engine: the 24 archetype-core copies give about a 98% chance of at least one core card in a 5-card opening hand, and 16 searchers give about 90% for at least one searcher (Inferred from hypergeometric estimates). It converts that access into boards through a dense Link and Fusion Extra Deck, with several 2400 to 3000 ATK bosses, and the GY recursion keeps the engine going after a break. Interaction is layered across seven hand traps plus Crossout Designator, Monster Reborn and Infinite Impermanence, which gives it a reasonable going-second answer. Costs are the 18 off-archetype copies (Horus, Mulcharmy, Dark Magician, Forbidden, Chaos, Dragunity and others) that create some engine conflict, the 15-slot Extra Deck with 9 Link summons, and no sideboard or combo data to confirm the median output. Popularity (the 80% usage stats) confirms the list is a real, accessible build, but it did not earn points by itself, and the score was built from the system rather than from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo weights not blended since the combo evidence is absent. Structural ≈ 62.8, Going First ≈ 66, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Engine conflicts (-3); Banlist exposure (-1); Hand-trap redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Strong starter access: 98% chance of a core card and 90% chance of a searcher in a 5-card hand (Inferred)
• Layered interaction: seven hand traps plus Crossout Designator, Monster Reborn and Infinite Impermanence (Verified card text)
• Repeated GY recursion (Quik-Fix, Sleeper, Big Red, Master Plan) keeps the engine alive after disruption (Inferred)
• Boss variety across Link, Fusion, Xyz and Synchro end-boards (Verified stats)

Weaknesses

• 18 off-archetype copies create engine conflicts and brick risk (Verified composition, Inferred impact)
• Core Extra Deck cards (Double Helix, Red-Eyes Dark Dragoon, Dark Magician of Destruction, Masquerena) are missing from a list where they are 80% core (Verified usage stats)
• No combo evidence, so the floor and median are unmeasured (Provisional)
• High pilot complexity from Horus, SPYRAL and Mulcharmy chains (Inferred)

Critical choke points

• SPYRAL monsters in the GY as the main recursion source; too few banished SPYRAL cards blocks Sleeper and Big Red (Inferred)
• King's Sarcophagus is needed for Horus GY Special Summons; without it the Horus half of the engine does not run (Verified card text)

• Inferred: Engine access and consistency estimates from hypergeometric odds; Interaction and hand-trap coverage from role flags and card text; Structural and final score calculations; Engine conflicts from off-archetype spread
• Provisional: Meta Power is null: no dated metagame sample; Tournament reliability and matchup fit: no tournament link; Combo floor and median: no recorded boards; Side-deck dimension: no sideboard in the format
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry for going-first/second, matchup, or brick/starter/OTK rates Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no sideboard; post-side scoring is not applicable
