Legality

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

Identity & game plan

  • Win condition: Layered Fusion/Synchro board with negation and removal bosses; Grind via Bystial banish recursion and Branded Regained draws
  • Turn 1 (going first): Open starter (Branded/Bystial) to fusion/synchro into negate bosses and set disruption
  • Turn 2 (going second): Use hand traps and board breakers to disrupt then establish smaller board
  • Recovery: Branded Regained, Bystial searches, GY recursion from Extra Deck monsters
  • After siding: None (side deck absent)

Why it scores here

This deck is evaluated as a connected Branded/Bystial combo system that leverages Dragon searchers and fusion/synchro bridges to produce layered disruption boards. Consistency is supported by multiple 3-copy starters and a high probability of opening a searcher, though singleton extras and limited copies introduce variance. The ceiling includes multiple negation bosses (Dis Pater, Rindbrumm, Mercourier) but the median output is more modest and fragile to single interruptions due to one-of extra deck pieces. No tournament win rates or parsed combos were available, so Meta Power is provisional and the score reflects inferred structural power rather than archetype popularity, and individual card scores were not averaged.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 75 Multiple 3-copy starters (Seyfert, Lubellion, Ecclesia) yield P(open≥1)~0.34 each, union high; searcher group P=0.95 (Inferred)
D2 Opening-Hand Quality & Brick Management 65 16 singleton main cards and several garnet-ish techs suggest moderate brick risk (Inferred)
D3 Combo Conversion & Ceiling 80 Extra deck provides multiple negate bosses (Dis Pater, Rindbrumm) enabling high ceiling board (Inferred)
D4 Combo Floor & Median Output 60 No parsed combos; median expected single fusion + synchro with one disruption (Inferred)
D5 Interruption Resilience & Route Redundancy 65 Redundant Bystial banish and Branded fusion from hand give some route redundancy, but extra deck one-ofs limit (Inferred)
D6 Resource Economy, Recovery & Grind 60 Branded Regained and Magnamhut search provide moderate grind; net advantage unclear (Inferred)
D7 End-Board & Interaction Quality 70 Negation text on 4 cards and removal on 14 support interactive end board (Inferred from flags)
D8 Going-Second & Board-Breaking Power 45 Only 2 hand traps and few board breakers yields weak going-second plan (Inferred)
D9 Offensive Pressure & Closing Power 65 Bosses up to 3500 ATK and attack-all Chaos Archfiend enable closing (Inferred)
D10 Main Deck Efficiency & Flexibility 70 40-card compact list with clear engine cores but singleton dilution (Inferred)
D11 Extra Deck Efficiency & Coverage 65 15 extra deck slots used for 9 fusion/6 synchro covering many lines but mostly one-of (Inferred)
D12 Side Deck Adaptability 10 Side deck absent (0 cards) so post-side adaptability nonexistent (Verified)
D13 Matchup Coverage & Format Fit 50 No dated metagame sample; format fit provisional neutral (Provisional)
D14 Pilotability & Error Tolerance 55 Mixed fusion/synchro lines create moderate complexity and error tolerance (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 66, Going First ≈ 70, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: no Side Deck (-3); banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

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

  • Multiple redundant Dragon searchers and starters
  • Diverse fusion/synchro extra deck with negation bosses
  • Bystial banish mechanics provide removal and recursion

Weaknesses

  • Singleton extra deck pieces create choke points
  • No side deck for best-of-3 adaptation
  • Limited copies of key cards reduce consistency

Critical choke points

  • PSY-Framelord Omega Limited to 1 copy
  • Bystial Magnamhut Limited to 1 copy
Priority Remove Add Reason
1 Gold Sarcophagus Super Polymerization Gold Sarc is slow and dead weight; Super Poly improves going-second board breaking (unlimited in Master Duel)

Evidence & confidence

  • Verified: Legality status Legal; Side count 0; Restricted cards within copy limits; Extra deck 15 cards legal
  • Observed: No parsed combos (0 boards) in evidence; Usage stats show deviation from typical core
  • Inferred: Consistency probabilities from hypergeometric; Strategy classification Combo/Toolbox; Dimension scores from card text and composition; Going-first/second power estimates
  • Provisional: Matchup format fit (no dated meta); Meta Power null
  • 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 — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
