SPYRAL Deck #773828 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 50/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link and Synchro boss monsters (SPYRAL Double Helix, Ancient Fairy Dragon, Baronne de Fleur, Cupsy and Cooky Yummy Way Synchros) and the 2800 ATK SPYRAL Sleeper, which is Special Summoned from the Graveyard by banishing 3 SPYRAL cards.; Red-Eyes Dark Dragoon and Dark Magician of Destruction from the Extra Deck (listed in the Extra Deck, but absent from the usage-statistics core check; see data gaps).
• Turn 1 (going first): Open a searcher or starter (Snake-Eye Ash or Oak, SPYRAL Quik-Fix, Diabellstar, Marshmao or Cooky Yummy) and extend into a Link-1 or Level 2 Synchro to enable the Yummy Special Summons (Inferred from card text).
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C and Forbidden Droplet to answer the opponent's summons and searches, then convert the open turn with a searcher (Inferred).
• Recovery: SPYRAL Resort and SPYRAL Master Plan re-add SPYRAL pieces each turn; SPYRAL MISSION - Rescue and Quik-Fix return Graveyard monsters (Inferred from card text).
• After siding: No Side Deck is registered (0 cards), so there is no post-side plan; adaptation is limited to in-game choices.

Why it scores here

The deck reliably opens a searcher or starter in most hands, since the searcher-text group (26 copies) has a hypergeometric P of about 0.95 of at least one in a 5-card opening hand, though this is a proxy and not a verified starter rate (Inferred). It converts into pressure through several independent routes (SPYRAL, Yummy, Snake-Eye, Diabellstar, Allure Queen), but no recorded boards exist, so the ceiling and median are text-only estimates. Interaction is broad (6 hand traps, 8 negation texts, 19 removal texts), which supports its going-second plan. The score comes from consistency, interaction and the system's coherence, not from the popularity of SPYRAL, and not from averaging the card scores. Engine conflicts (only 22.7 percent exact-name purity across five sub-archetypes), the lack of a side deck, and eight Limited single-copy engine cards pull the score down.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-3); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*55 + 0.20*52 = 54.4, then -4 modifiers = 50.4, rounded to 50

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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 searchers and multiple independent starters reduce dead hands
• Broad interaction on the going-second turn (6 hand traps, 8 negation texts)
• Extra Deck covers Link, Synchro and Fusion routes

Weaknesses

• Five sub-archetypes compete for the same resources; exact purity 22.7 percent
• No Side Deck (0 cards) and no post-side plan
• Eight single-copy Limited engine cards create dependence on specific draws
• No recorded boards, so the combo ceiling and floor are unverified

Critical choke points

• Enabling Yummy Special Summons requires a Link-1 or Level 2 Synchro on the field (Inferred from card text)
• SPYRAL Sleeper needs 3 SPYRAL cards in the Graveyard to be Special Summoned

Recommended changes

Evidence & confidence

• Verified: Main 60, Extra 15, Side 0 are within Master Duel size rules (main 40-60, extra 0-15, side 0-15); All 10 restricted cards are within legal copy limits (8 Limited at 1 copy, 2 Semi-Limited at 2 copies); Copy histogram: 8 cards at 3 copies, 6 at 2, 24 at 1 (60 main); Archetype core presence 73.9 percent from usage statistics
• Inferred: P(at least one 3-copy starter in opening hand) about 0.23 per card; Searcher-text group about 0.95 at least one in 5 cards (proxy only); Toolbox weight profile chosen from engine sprawl and interaction density; Engine conflicts and banlist exposure modifiers
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit and D13 (no tournament link); Side deck adaptability and D12 (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 match record absent No win-rate telemetry exists in YGOVN; going-first and going-second rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Usage statistics mark Linkuriboh, Red-Eyes Dark Dragoon, Dark Magician of Destruction, SPYRAL Double Helix, I:P Masquerena and S:P Little Knight as not in this deck, but the card list places all six in the Extra Deck; the core-presence figure may be understated and was not used for scoring No Side Deck registered; D12 is Provisional Only one guide, and its snippet is partial
