Legality

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

Identity & game plan

  • Win condition: K9 Xyz bosses (K9-X Werewolf 3300 ATK, Divine Arsenal AA-ZEUS 3000 ATK, Number C104 Umbral Horror Masquerade Victory 3000 ATK) reached through hand-trap-protected summons; Dark Time Wizard and Mulcharmy card advantage and recursion, plus Red-Eyes Black Dragon Exceed as a Fusion finisher
  • Turn 1 (going first): Open a K9 or Dark Time Wizard starter (about 81% for at least one core card in a 5-card hand), search with Case for K9 or Fire Formation - Tenki, and build toward an Xyz; hand traps stay in hand for the opponent's first activation
  • Turn 2 (going second): Use the 6-card hand's hand-trap density (about 89% to hold at least one hand trap) to answer the opponent's board, then Normal Summon K9 monsters that need no tribute
  • Recovery: Recover through Foolish Graverobber, Droll and Lock Bird, and Mulcharmy draws; this is textual and unmeasured
  • After siding: None: the list runs 0 side cards, so there is no post-side plan to evaluate

Why it scores here

The deck is illegal as built: Ash Blossom & Joyous Spring and K9-17 Izuna are each run three times against an OCG limit of two, so the score is capped and the evaluation is structural-only. Its structural read comes from the system, not from averaging card scores: about 81% of hands hold at least one archetype-core card, about 89% of going-second hands hold a hand trap, and the Xyz bosses carry strong interaction (Inferred). The deck runs three engines (K9, Dark Time Wizard, Mulcharmy) with only 15.7% exact-name K9 purity, which lowers engine cohesion and pilotability. There are no recorded boards, no side deck and no tournament record, so floor, median and meta are unmeasured. Archetype popularity earned no points.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one core card in a 5-card hand) is about 0.81 across 15 core copies; multiple starters but engines conflict (Inferred)
D2 Opening-Hand Quality & Brick Management 52 16 hand traps and 13 searchers sit beside a roughly 19% proxy full-brick rate with no non-tech dead cards filtered (Inferred)
D3 Combo Conversion & Ceiling 55 Ceiling from card text alone: K9 Xyz chains and Number-class Xyz bosses reach 3000+ ATK, but no boards were recorded (Inferred)
D4 Combo Floor & Median Output 40 Median output is unmeasured because combos_evidence is empty; scored conservatively at 40 (Provisional)
D5 Interruption Resilience & Route Redundancy 60 Three copies of Ash Blossom and Izuna plus Droll, Infinite Impermanence and Evenly Matched give multiple interruption routes (Inferred)
D6 Resource Economy, Recovery & Grind 58 Mulcharmy draw triggers and Foolish Graverobber recursion add card economy; no resource data was recorded (Inferred)
D7 End-Board & Interaction Quality 72 Solemn Judgment, Harpie's Feather Duster, Lightning Storm, Jinzo and Masquerade removal form a layered end-board package (Inferred from text)
D8 Going-Second & Board-Breaking Power 66 Going-second hand-trap density is about 0.89 for at least one hand trap in hand 6, with Limited removal backing it (Inferred)
D9 Offensive Pressure & Closing Power 70 Several 3000+ ATK Xyz bosses and direct-attack text support a closing plan (Inferred)
D10 Main Deck Efficiency & Flexibility 45 55 main cards hold 28 distinct names with 24 off-archetype copies and 20 tech slots, which lowers compactness (Verified composition, Inferred effect)
D11 Extra Deck Efficiency & Coverage 55 Extra Deck is 10 Xyz, 4 Link and 1 Fusion, with 15 of 15 core Extra cards present (Verified)
D12 Side Deck Adaptability 10 No side deck is registered, so there is no adaptability and this is scored near zero (Verified)
D13 Matchup Coverage & Format Fit 50 No tournament link or dated meta sample, so matchup fit is withheld and held at neutral (Provisional)
D14 Pilotability & Error Tolerance 35 Three engines, many optional hand-trap decisions and Xyz sequencing make this demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine_conflict (-4); no_side_deck (-2). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(48) + modifiers(-6) = 47.6 raw; Illegal cap applied -> 35 (theoretical/structural-only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.81 · key two-card combo ≈ — · full-brick estimate ≈ 0.19 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Layered interaction: 16 hand traps, Solemn Judgment, Harpie's Feather Duster, Lightning Storm and Masquerade removal
  • High going-second hand-trap density
  • Strong Xyz bosses with 3000+ ATK and multiple engine routes
  • Full 15-card Extra Deck with the core Xyz and Link cards present

Weaknesses

  • Illegal as built: Ash Blossom & Joyous Spring and K9-17 Izuna each run 3 copies against an OCG limit of 2
  • Three engines (K9, Dark Time Wizard, Mulcharmy) with only 15.7% exact K9 purity
  • No side deck, so no post-side plan
  • No recorded boards, so the combo floor and median are unmeasured
  • 24 generic cards and 20 tech slots dilute the main deck

Critical choke points

  • Copy-limit fix forces Ash Blossom and Izuna down to 2 copies each
  • Six Limited single-copy cards (Droll and Lock Bird, Case for K9, Harpie's Feather Duster, K9-66a Jokul, S:P Little Knight, Solemn Judgment) limit redundancy
  • K9 Xyz lines depend on Extra Deck summons, so a removed Extra card breaks the core
Priority Remove Add Reason
1 One copy of Ash Blossom & Joyous Spring A legal main-deck slot or a side-deck card Brings the card to the OCG Semi-Limited limit of 2 so the list is legal
2 One copy of K9-17 Izuna A legal main-deck slot or a side-deck card Brings the card to the OCG Semi-Limited limit of 2 so the list is legal
3 None A side deck of up to 15 legal cards A side deck is the only way to score D12 and to get a post-side plan
4 Some of the 24 generic and off-archetype tech slots Core K9 or Dark Time Wizard support Improves engine cohesion and lowers the 15.7% purity

Evidence & confidence

  • Verified: Illegal: Ash Blossom & Joyous Spring and K9-17 Izuna at 3 copies each against OCG limit 2; Main 55, Extra 15, Side 0; Main and Extra sizes are legal; Six Limited single-copy cards are present; Exact-name K9 purity 15.7%; 11 of 55 main cards are exact K9 names
  • Inferred: P(at least one core card in a 5-card hand) about 0.81 and proxy full-brick about 0.19; Hand-trap density for going second about 0.89; Interaction layering and Xyz boss strength from card text
  • Provisional: Median output and meta position; no combos or tournament data; Matchup fit and tournament reliability
  • Data gaps: No combos supplied: floor, median and ceiling rest on card text only No tournament link: archetype meta-share and pilot match record absent No side deck: post-side plan unmeasurable usage_statistics in_this_deck flags mark K9-X Werewolf, N.As.H. Knight, CXyz N.As.Ch. Knight, S:P Little Knight, K9-17 Ripper and Divine Arsenal AA-ZEUS as absent, but all six appear in the Extra Deck card list; the card list was used as the source of truth, so the reported 60% core coverage is understated No win-rate telemetry for going-first/second, matchup or brick/OTK rates; these are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
