Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Xyz Summon high-ATK K9 and Clown Crew Extra Deck monsters (K9-X Werewolf 3300, Divine Arsenal AA-ZEUS 3000) and convert the board with attacks and Clown Crew Diabolo piercing; Number C104 Masquerade Victory and Clown Crew Dristy second-attack pressure off Tribute Summons
  • Turn 1 (going first): Open with K9 and Clown Crew searchers and Normal Summon K9-66a Jokul or K9-66b Lantern without Tribute, then build an Xyz with a Level 5 pair; hold Ash Blossom and Solemn Strike for opposing starters
  • Turn 2 (going second): Use Ash Blossom, Solemn Strike, Nibiru and Clown Crew Biancaviso to disrupt the opponent's first summon chain, then rebuild with K9-X Forced Release and the Xyz Extra Deck
  • Recovery: Mulcharmy Fuwalos draw and Clown Crew Flair or Clown Crew Rehearsal recursion through the GY, with K9 Xyz effects that re-summon from the Extra Deck
  • After siding: Not evaluable: the Side Deck is empty (Side Deck size 0), so no post-side plan exists in this list

Why it scores here

The deck is scored as a system, not as an average of its cards. Its core engine is reasonably reliable: the hypergeometric estimate of at least one K9 core card in a 5-card opening hand is about 0.78 (Inferred), and the Clown Crew and K9 searchers give it redundant starts. Its interaction is the strongest part of the list, with Ash Blossom, Solemn Strike, Nibiru and Lightning Storm covering many lines, which earns the D7 score. Conversion is unproven: no combos were supplied, so the ceiling and median are text-only inferences and the deck earns only moderate D3 and D4 scores. The list is illegal as built: Ash Blossom and K9-17 Izuna run three copies against a Semi-Limited limit of two, so it receives a capped score. Popularity or archetype usage did not add points; the usage statistics only confirm that the core cards are real and accessible.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one core K9 card in hand of 5) ≈ 0.78; 2-card bootstrap via K9-66 Jokul and K9-66b Lantern (Inferred)
D2 Opening-Hand Quality & Brick Management 48 Brick proxy about 0.22 for no core card in hand of 5; 17 Tech or hand-trap slots compete with 14 three-copy cards (Inferred)
D3 Combo Conversion & Ceiling 52 No parseable boards; ceiling from K9-X Werewolf 3300 and Divine Arsenal AA-ZEUS 3000 Extra Deck access via text only (Inferred)
D4 Combo Floor & Median Output 45 No combo records, so median output cannot be measured; the estimate is a text-based guess (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Six hand traps plus Ash Blossom and Solemn Strike give several independent interruption answers, but no alternate line is verified (Inferred)
D6 Resource Economy, Recovery & Grind 60 Mulcharmy Fuwalos draw, Clown Crew Flair and Rehearsal recursion, and Preparation of Rites give real grind text (Inferred)
D7 End-Board & Interaction Quality 68 Three Ash Blossom plus Solemn Strike, Lightning Storm and Dimensional Fissure give broad interaction, though Ash is over the copy limit (Inferred semantic)
D8 Going-Second & Board-Breaking Power 62 Going-second hand-trap density is about 0.52 for at least one hand trap in hand of 6; no going-second combo split is available (Inferred)
D9 Offensive Pressure & Closing Power 58 Werewolf 3300, Zeus 3000 and Number C104 3000 give high end-board ATK; Diabolo gives piercing text (Verified card text, Inferred use)
D10 Main Deck Efficiency & Flexibility 42 24 distinct main-deck cards with 3-copy staples, 31 level-0 non-monsters, and 28 of 55 cards in one sub-archetype reduce flexibility (Verified counts, Inferred)
D11 Extra Deck Efficiency & Coverage 58 Extra Deck is full at 15 with 9 Xyz, 2 Link, 2 Fusion and 2 Synchro; several Extra slots are mandatory engine pieces (Verified count, Inferred)
D12 Side Deck Adaptability 15 Side Deck is empty (Side Deck size 0), so no post-side adaptability exists (Verified)
D13 Matchup Coverage & Format Fit 50 No dated metagame sample or tournament link; archetype usage only confirms accessibility (Provisional)
D14 Pilotability & Error Tolerance 40 Multiple archetype sub-engines (K9, Clown Crew, Number, Masquerade) and conditional summon rules make the list demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts (-4); illegal-list cap (-18). Final formula: 0.80*Structural(54.2) + 0.20*TournamentReliability(40) = 51.4; modifiers -12 gives 39.4; capped to 30 because legality status is Illegal (copy-limit violations). Meta Power provisional, excluded.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Core K9 engine is accessible on the going-first hand (about 0.78)
  • Strong interaction density with Ash Blossom, Solemn Strike, Nibiru and Lightning Storm
  • High end-board ATK from K9-X Werewolf and Divine Arsenal AA-ZEUS

Weaknesses

  • Illegal as built: Ash Blossom and K9-17 Izuna exceed the Semi-Limited copy limit
  • No Side Deck, so no post-side plan
  • Low archetype purity: 14.3 percent exact K9 name, with a large off-archetype Clown Crew block

Critical choke points

  • Ash Blossom and Izuna both sit on the illegal copy limit, so the list must drop one copy each to be playable
  • The Clown Crew and K9 engines both depend on a few Extra Deck Xyz monsters, so losing one breaks the line
Priority Remove Add Reason
1 one copy of Ash Blossom & Joyous Spring and one copy of K9-17 Izuna one non-restricted replacement each, or a second Side Deck-legal copy-limit fix Removes the copy-limit violation that makes the list illegal and lifts it out of the capped score band
2 one Clown Crew Rehearsal or Clown Crew Finale a Side Deck of 10 to 15 cards Creates a post-side plan, which the list currently lacks entirely

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 are within OCG size rules (40-60, 0-15, 0-15); Ash Blossom and K9-17 Izuna run 3 copies against a Semi-Limited legal limit of 2 (illegal); K9-66a Jokul and A Case for K9 run 1 copy each against a Limited limit of 1 (legal); Hand-trap, floodgate and tech counts come from the evidence pack
  • Observed: Core-card inclusion percentages from usage statistics: K9-00 Lupis 85 percent, K9-66a Jokul 80 percent, Mulcharmy Fuwalos 69 percent
  • Inferred: At least one core K9 card in a 5-card opening hand is about 0.78; Going-second hand-trap availability is about 0.52; Interaction and resilience scores are semantic reads of card text
  • Provisional: Meta power and matchup fit: no dated metagame sample or tournament link
  • 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 are absent No win-rate telemetry for going-first, going-second, matchup or brick rates Side Deck is empty, so post-side scoring cannot be evaluated Meta Power is provisional without a dated metagame sample
