Stardust Bystial Deck #770641 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro boss beats (Red Supernova Dragon, Tyrant Red Dragon Archfiend, Bystial Dis Pater, Red Nova Dragon) after Resonator and Archfiend Synchro lines; Red Dragon Archfiend and Hot Red Dragon Archfiend Abyss/Bane pressure, with Crimson Gaia and Crimson Call searches
• Turn 1 (going first): Resonator Call or Vision/Soul Resonator search, then Tuner plus non-Tuner into a Synchro boss, holding Ash Blossom, Infinite Impermanence or Droll as protection
• Turn 2 (going second): Hold Ash, Droll, Maxx C and Dominus Impulse to break the opponent's starter, then rebuild through Resonator searches and Synchro Summons
• Recovery: Recover through GY Resonators (Synkron, Soul, Vision, Crimson Resonator) and Crimson Call, then re-Synchro into a boss
• After siding: No side deck is run, so there is no post-side plan; Master Duel play is single-game

Why it scores here

The deck is scored as a Synchro-midrange system, not from its popularity or from averaging card scores. Its searchers (16 searcher-text cards, about 93.5% chance of at least one in a 5-card opening hand) and the 12-copy archetype core (about 85% at least one in hand) give it a reliable way to open a Tuner and Synchro line. Nine hand traps and about nine negation and eleven removal effects let it interrupt the opponent and recover through GY Resonators, which keeps the midrange plan alive after disruption. Its finishers (Red Supernova, Tyrant, Dis Pater, Red Nova, Bane) give the deck closing power. The score is held down by the absence of a side deck, the lack of any recorded combos or tournament data, and a main deck that spans several sub-archetypes (only 0% exact-name purity). The archetype label Stardust Bystial does not match the list, which is mostly Resonator and Red Dragon Archfiend, so the score reflects the list as built.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62.7, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: No side deck (-2). Final formula: 0.80*Structural(62.7) + 0.20*TournamentReliability(58) + ContextModifiers(-2) = 59.7, rounded to 60 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Reliable searcher density (16 searcher-text cards) gives a high starter-access rate
• Nine hand traps and layered negation give interaction on both turns
• Strong Synchro boss ceiling (3000-4000 ATK)
• Legal list with all restricted cards at legal copy counts

Weaknesses

• No side deck, so no adaptability or post-side plan
• No recorded combos or tournament data, so the ceiling and median are unverified
• Mixed sub-archetype build makes engine coherence depend on specific Resonator and Archfiend pieces
• Archetype label does not match the list

Critical choke points

• Red Dragon Archfiend and Tyrant are the main closers; losing them to one removal leaves weaker bosses
• Maxx C and Magnamhut are single-copy Limited cards, so losing either costs the only copy

Recommended changes

Evidence & confidence

• Verified: Legal size (40/15/0) with Master Duel size rules; Restricted cards at legal copy counts (Magnamhut 1 Limited, Maxx C 1 Limited, Droll 2 Semi-Limited); Copy histogram 12x1, 5x2, 6x3; Core-group hypergeometric P(>=1 in hand 5) 0.85
• Observed: Usage statistics show Droll, Maxx C, Ash, Mulcharmy and Fydraulis as archetype staples
• Inferred: Brick rate and starter-access estimates; Interaction density from text; Ceiling and median output from text only; Going-first and going-second strength
• Provisional: Matchup and format fit (no meta sample); Meta power (null)
• 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 No win-rate telemetry for going-first, going-second or matchups Meta power is provisional without a dated metagame sample Archetype label Stardust Bystial does not match the list; archetype-level stats may not apply
