Identity & game plan

  • Win condition: Xyz pressure from K9 Level 5 and Level 9 Xyz monsters (K9-X Werewolf 3300 ATK, K9-X Ripper/M 3100 ATK with piercing) backed by Vanquish Soul beaters (Caesar Valius 3000 ATK, Heavy Borger 2500 ATK); Vanquish Soul board takeover through Hollie Sue and Snow Devil; Number subengine via N.As.H Knight and Number 104 Masquerade in the Extra Deck
  • Turn 1 (going first): Open a 15-searcher-density hand, Normal Summon a K9 Level 5 (no tribute with 2+ opposing cards), search the Vanquish Soul or K9 support, and reach a Level 5 Xyz on turn 2 through Lupis, Jokul or Izuna material
  • Turn 2 (going second): Use the six-card hand to present a hand trap (Ash Blossom, Ghost Ogre, Maxx C) against the opponent's first summon or search, then Quick-Effect Hollie Sue or Dr. Mad Love to rebuild the board
  • Recovery: Chaotic Elements, A Case for K9 and Lantern recover Level 5 starters from Deck and GY; Maxx C and Mulcharmy draw cards when the opponent Special Summons
  • After siding: No side deck is registered (side 0). The post-side plan is unevaluated and scored as a weakness.

Why it scores here

The deck's score comes from the system, not from its cards: 15 searcher-text effects and three-copy starters (Izuna, Dr. Mad Love, Hollie Sue) make a live Level 5 starter likely early (P of at least one searcher in an opening 5 is about 0.92, Inferred), and six hand traps keep interruption and going-second answers available. Offensive closing power is the strongest component, since K9-X Werewolf, K9-X Ripper/M and Vanquish Soul Caesar Valius all reach 3000+ ATK. Two engines (K9 and Vanquish Soul) plus a Number subengine, Mulcharmy and Bystial tech, dilute the main deck and cost consistency and pilotability. No combo boards, tournament link, or side deck are present, so the floor and median are unmeasured and the post-side plan scores low. Archetype popularity (the K9 core is in the list) confirms the deck is real and accessible but earned no points on its own.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 72 P(at least one of 3 copies of a 3-copy starter in a going-first 5-card hand) = 0.338; searcher-text group P(>=1 in hand5) = 0.919 (Inferred)
D2 Opening-Hand Quality & Brick Management 66 Six hand traps (Ash, Ghost Ogre, Maxx C) plus 16 singletons; going-second P(>=1 hand trap in 6 cards) = 0.650 (Inferred)
D3 Combo Conversion & Ceiling 65 No parseable boards; ceiling inferred from 3000+ ATK Xyz finishers and Vanquish Soul board takeover text (Inferred)
D4 Combo Floor & Median Output 52 No combo evidence; median output not measurable, lowered for dual-engine conflict (Provisional)
D5 Interruption Resilience & Route Redundancy 70 Multiple independent starters (Izuna, Dr. Mad Love, Hollie Sue, Jokul, Lupis) and hand-trap redundancy after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 70 Searchers (Chaotic Elements, A Case for K9, Razen, Start!) and draw effects (Maxx C, Mulcharmy Fuwalos) support recovery (Inferred)
D7 End-Board & Interaction Quality 74 Eleven removal-text and three negation-text cards; Lupis is untargetable by card effects when used as Xyz material; Forced Release destroys (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 72 Six hand traps and Snow Devil/Heavy Borger/Caesar Valius give going-second board breaking; Druiswurm and Magnamhut are DARK removal beaters (Inferred)
D9 Offensive Pressure & Closing Power 80 End-board ATK: Werewolf 3300, Ripper/M 3100 with piercing, Zeus 3000, Caesar Valius 3000 (Verified stat)
D10 Main Deck Efficiency & Flexibility 58 26 distinct main cards, 16 singletons, 40 slots with Mulcharmy (3), Bystial (2) and Umbral/Number tech diluting K9 (15 exact-name copies, 27.3% purity) (Verified composition)
D11 Extra Deck Efficiency & Coverage 58 12 Xyz and 3 Link Extra cards; roughly 8 of 15 Extra slots serve a second engine or tech (Numbers, Arc Rebellion, Zeus, TY-PHON, S:P Little Knight) (Verified composition, Inferred role)
D12 Side Deck Adaptability 25 Side count is 0; no post-side plan exists (Verified)
D13 Matchup Coverage & Format Fit 50 No tournament link or dated meta sample; archetype meta-share absent (Provisional)
D14 Pilotability & Error Tolerance 45 Multiple engines, Quick-Effect Vanquish Soul reveals, and tribute-free K9 summons create many decision points (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 64.6, Going First ≈ 71, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 61. Modifiers: No side deck (-2); Engine conflicts (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*64.6 + 0.20*61 - 5 = 58.9)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.92 · 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 text (15 cards) and three-copy starters give high Level 5 access on going first (Inferred)
  • Six hand traps and eleven removal-text cards cover both disruption and going second (Inferred)
  • Extra Deck offers 3000+ ATK Xyz finishers with piercing, Werewolf and Ripper/M (Verified stats)

Weaknesses

  • Two archetype engines (K9 15 copies, Vanquish Soul 18) and tech splash (Mulcharmy, Bystial, Umbral) dilute consistency (Verified composition)
  • No side deck, so no post-side plan (Verified)
  • Hand-trap-heavy hands can be non-functional without a starter (Inferred)
  • No combo or tournament evidence to confirm the floor or median (Verified gap)

Critical choke points

  • A Level 5 starter in hand for turn 1: several engines need a Level 5 monster in hand or GY (Inferred)
  • Ash Blossom, Ghost Ogre and Maxx C are the only hand-trap answers to the opponent's first summon or search (Inferred)
Priority Remove Add Reason
1 Mulcharmy Purulia (1) A Level 5 K9 or Vanquish Soul monster Off-engine draw tech adds a dead card in a hand needing starters (Inferred)
2 Number 104: Masquerade or Number C104: Umbral Horror Masquerade Second copy of a core Xyz (K9-66X Jacks or K9-17 Ripper) The Number subengine needs its own materials and conflicts with the K9 Xyz plan (Inferred)
3 A 15-card side deck A side deck is legal (sideMax 15) and would give a post-side plan for the matchups that need one (Inferred)

Evidence & confidence

  • Verified: Legal status; 40 Main / 15 Extra / 0 Side; all restricted cards at legal copy limits; Composition: 15 exact K9 copies, 18 Vanquish Soul copies, 27.3% exact-name purity; ATK values of the listed Xyz and beater monsters
  • Inferred: Starter access and brick estimates from hypergeometric draws; Hand-trap and removal coverage from card text; Engine-conflict and pilotability reads from card text
  • Provisional: Meta Power (null); D13 matchup and format fit
  • 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 side deck: post-side plan cannot be assessed usage_statistics in_this_deck flags ignore the Extra Deck: K9-X Werewolf, K9-66X Jacks, K9-17 Ripper, Number 104 Masquerade, Rock of the Vanquisher and others appear as absent although they are in the list. Only Droll & Lock Bird and Saryuja Skull Dread are truly absent from the Main Deck, so core_cards_present 14/25 is overstated and was not used. Archetype core brick proxy (0.94%) depends on an unverified core group definition and was not used No win-rate telemetry exists in YGOVN
