Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

  • Win condition: Floodgate lock plus incremental hand-trap advantage; Xyz beatdown with rank-5 bosses
  • Turn 1 (going first): Set Dimensional Fissure / There Can Be Only One, establish hand traps and a small negate board
  • Turn 2 (going second): Break with S:P Little Knight / K9-X Forced Release and hand traps
  • Recovery: Mulcharmy draws, Pot of Prosperity, K9/Lupis recursion
  • After siding: No side deck (0 cards) – cannot adapt in best-of-3

Why it scores here

This deck is evaluated as a connected system, not as an average of its individual cards, and its popularity or archetype meta-share earned no points. The 55-card main deck dilutes the Vanquish Soul and K9 engines, yielding moderate opening consistency but high brick risk from floodgates and dead extra-deck bosses. Without parsed combos, the median output is inferred as a passive floodgate-plus-hand-trap board rather than a proactive combo, and the lack of a side deck removes best-of-3 adaptability. The score reflects a bloated control/midrange pile with interaction but poor conversion and efficiency.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 65 Hypergeometric P(≥1 of 24 core copies in 5) ≈ 0.95 but 55-card size dilutes individual starters (Inferred)
D2 Opening-Hand Quality & Brick Management 50 55-card list with 3 Dimensional Fissure and singleton garnet extra cards raises brick risk (Inferred)
D3 Combo Conversion & Ceiling 45 No parsed combos; text suggests rank-5 Xyz ceiling but Zeus/TY-PHON unreachable (Inferred)
D4 Combo Floor & Median Output 40 Median output likely a floodgate plus hand traps, low proactive board (Inferred)
D5 Interruption Resilience & Route Redundancy 55 Multiple hand traps and floodgates provide some resilience but engine single-choke (Inferred)
D6 Resource Economy, Recovery & Grind 60 Dimensional Fissure + Mulcharmy draw + Pot of Prosperity support grind (Inferred)
D7 End-Board & Interaction Quality 60 Floodgates + Solemn Judgment + Xyz negates yield moderate interaction (Inferred)
D8 Going-Second & Board-Breaking Power 45 S:P Little Knight and K9 Forced Release aid breaking but 55-card hand quality low (Inferred)
D9 Offensive Pressure & Closing Power 40 Bosses like K9 Werewolf exist but rarely summoned; low closing power (Inferred)
D10 Main Deck Efficiency & Flexibility 40 Main deck 55 cards with many singles reduces efficiency (Inferred)
D11 Extra Deck Efficiency & Coverage 50 Extra deck has dead 12-rank monsters; useful Ripper/Number 104 present (Verified/Inferred)
D12 Side Deck Adaptability 10 Side deck empty (0 cards) – no post-side adaptation (Verified)
D13 Matchup Coverage & Format Fit 50 No dated metagame sample; format fit provisional (Provisional)
D14 Pilotability & Error Tolerance 45 Mixed engines and floodgate timing create pilot error risk (Inferred)

How the score was computed

Strategy profile: Control. Structural ≈ 50, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: engine conflicts (-3); hard-garnet burden (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • High density of hand traps and floodgates for interaction
  • Multiple negation sources via Solemn Judgment and Xyz effects

Weaknesses

  • 55-card bloat reduces consistency and opening-hand quality
  • Many dead extra-deck cards (Zeus/TY-PHON) and conflicting floodgates
  • No side deck to adapt post-side

Critical choke points

  • Reliance on Level 5 monsters for K9/Xyz without sufficient tutors
  • There Can Be Only One limits own board types
Priority Remove Add Reason
1 Divine Arsenal AA-ZEUS - Sky Thunder Additional Vanquish Soul extender Extra deck slot wasted on unsummonable boss in this build

Evidence & confidence

  • Verified: Legality status Legal; Card text excerpts; Banlist Limited statuses for restricted cards; Side count 0
  • Inferred: Hypergeometric consistency estimates; Brick risk from 55-card size; Median board from card text; Extra deck dead weight
  • Provisional: Matchup coverage without dated metagame
  • 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 usage statistics core cards list mismatches actual deck contents (possible export error)
