SPYRAL Deck #773539 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Land a large Link/Synchro/Fusion boss (Baronne de Fleur, Red-Eyes Dark Dragoon, Dark Magician of Destruction, SPYRAL Sleeper) through SPYRAL search and recursion, with Yummy and Snake-Eye lines as secondary engines; Diabellstar and Snake-Eyes Diabellstar pressure, with Allure Queen as a fallback extender line
• Turn 1 (going first): Open on a SPYRAL search or Allure Dance/Quik-Fix route into a Link-1 or Level 2 Synchro bridge, then summon a boss with Herald or Baronne to protect the board
• Turn 2 (going second): Use Ash Blossom, Droll and Maxx C to break the opponent's first engine, then rebuild through SPYRAL GEAR and Master Plan recursion
• Recovery: Recycle SPYRAL monsters from the Graveyard via SPYRAL Resort and SPYRAL Master Plan, then re-search with Quik-Fix and Super Agent
• After siding: No side deck is registered in the export, so no post-side plan can be assessed

Why it scores here

The deck reliably opens a SPYRAL-based starter through its many searchers and Resort, with a 3-copy starter opening in roughly 23% of 5-card hands by hypergeometric estimate (Inferred). Its interaction suite is the strongest part of the system: six hand traps, Baronne de Fleur, Herald of the Arc Light and Red-Eyes Dark Dragoon give it several ways to answer a board, which supports the going-second and end-board scores. Conversion and median output cannot be measured because no recorded boards exist, so the combo ceiling and floor are text-only inferences with low confidence. The main deck is fragmented across SPYRAL, Yummy, Snake-Eye, Allure Queen, Diabellstar and Magician cards (exact archetype purity about 23%), which costs efficiency and pilot tolerance, and there is no side deck. The score comes from the system's consistency, interaction and boss density, not from SPYRAL's popularity and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (not separately weighted; Midrange profile used as-is). Structural ≈ 59, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-2); engine_conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*59 + 0.20*55 = 58.2, then modifiers -4 gives 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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

• Dense searcher and recursion text for consistent starts
• Six hand traps plus Droll give strong going-second interaction
• Several 2800-3000 ATK bosses across Extra Deck types

Weaknesses

• Fragmented engine with low exact archetype purity
• No side deck registered
• No recorded boards, so the combo ceiling is unverified

Critical choke points

• Starter access depends on a few 3-copy cards; full-brick risk is unmeasured
• Extra-Deck boss routing requires specific Link-1 or Level 2 Synchro bridges

Recommended changes

Evidence & confidence

• Verified: Deck is legal in master-duel with 60 main, 15 extra and 0 side; All 10 restricted cards are within their legal copy limits; Boss ATK values for Sleeper, Dark Magician of Destruction, Red-Eyes Dark Dragoon and Baronne de Fleur
• Inferred: Starter and hand-trap hypergeometric estimates; Interaction and recovery reads from card text; Consistency and brick-risk estimates
• Provisional: Meta power and matchup fit (no dated sample); Post-side plan (no side deck)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent usage_statistics marks SPYRAL Double Helix, Linkuriboh, Red-Eyes Dark Dragoon, Dark Magician of Destruction, I:P Masquerena and S:P Little Knight as missing, but all six are in the Extra Deck list; the core-present percentage (73.9) is likely an artifact of counting Extra-zone cards as absent No win-rate telemetry exists in YGOVN No side deck registered; post-side plan unassessable Meta Power is Provisional without a dated metagame sample Deck title is null in the export
