K9 Deck #704693 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 0/100 (±15 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Control
• Format: tcg

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon K9 boss monsters and establish interaction through repeated synchro/xyz lines; Hand trap disruption and going-second board breaking via removal suite
• Turn 1 (going first): Open a Level 5 Xyz monster via starters (Noroi, Lantern, Izuna, Jokul); establish negation/interaction
• Turn 2 (going second): Mulligan for hand traps (Ash, Ghost Ogre, Ghost Belle); use removal (Raigeki, Lightning Storm) and starters to rebuild and pressure
• Recovery: GY recursion and float mechanics on searchers (Chaotic Elements, K9-17 Ripper); Mulcharmy draw engines if board is empty
• After siding: Unknown due to 0-card side deck

Why it scores here

This deck is illegal in TCG format: it runs 3 copies of K9-04 Noroi (Forbidden) and 16 Extra Deck cards (maximum 15 allowed). Because of these hard violations, it cannot receive a normal Structural or Final Contextual score. The evaluation that follows is theoretical, treating the deck as if these violations were corrected. The core K9 engine is incomplete relative to the archetype baseline (36% of stat-tracked core present), missing key Xyz monsters like Number C104, AA-ZEUS, and Werewolf. Without combo evidence, the system's reliability and floor cannot be verified empirically. The high concentration of hand traps and removal (33 of 54 Main Deck slots) suggests defensive intent, but the list lacks a functional 0-card side deck for best-of-3 formats. Popularity metrics and archetype meta-share do not appear in the evidence and did not influence this evaluation.

Dimension scores

How the score was computed

Strategy profile: Combo (theoretical; illegal construction). Structural ≈ 38, Going First ≈ 44, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 22. Modifiers: Forbidden card violation (-100); Extra Deck over limit (-5). Final formula: ILLEGAL DECK — NO FINAL CONTEXTUAL SCORE. Theoretical Structural = 0.80·Structural (if corrected) + 0.20·TournamentReliability would ≈ 0.80·38 + 0.20·22 ≈ 35. Actual score = 0 (hard legal violation).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High hand-trap density (11 copies) provides strong going-second interaction
• Comprehensive removal toolkit (Raigeki, Lightning Storm, Spellbound) covers back-row and board threats
• Multiple independent starter cards (Noroi, Izuna, Jokul, Lantern, K9-ØØ Lupis) provide route redundancy
• Searcher float (Chaotic Elements, K9-17 Ripper) enables GY recursion and follow-up pressure
• Mulcharmy draw engines (Fuwalos, Purulia) convert empty boards into card advantage

Weaknesses

• ILLEGAL: Runs 3 copies of K9-04 Noroi (Forbidden in TCG); Extra Deck oversized (16/15)
• Incomplete core archetype — 36% of stat-tracked K9 core present; missing AA-ZEUS, Werewolf, C104 chain, N.As.H., CXyz N.As.Ch.
• 54 Main Deck size (vs 40–60 range) with heavy three-of concentration (13 distinct 3-ofs) increases brick rate and redundancy
• No side deck (0 cards) — cannot adapt for best-of-3 play; critical vulnerability in tournament contexts
• No combo evidence to verify system consistency, floor, or realistic output — all analysis is text-based inference
• Single Xyz destruction or Noroi ban removes core opener path; no unrecoverable choke-point safety

Critical choke points

• K9-04 Noroi (Forbidden) was the primary no-tribute opener; removal cripples T1 consistency
• Extra Deck oversized (16 vs 15) — illegal; also lacks mandatory core Xyz (AA-ZEUS, Werewolf) for resilient lines
• 0-card side deck — cannot board swap for common meta matchups; post-side plan non-existent
• Rank 5 Xyz as sole board layering (ATK 1700–2600 max) — ceiling insufficient vs modern board-breaking; missing Rank 12 reach (K9-X Ripper/M, Werewolf, AA-ZEUS)
• Combo data absent — cannot verify if the deck's theoretical consistency translates to tournament reliability

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Noroi 3×/Forbidden, Extra 16>15); Main Deck size: 54 cards (vs 40–60 legal range); Extra Deck size: 16 cards (vs 15 maximum); Archetype purity: 21 exact-name K9 (30%); 6 Mulcharmy, 3 R.B., 2 Cyclone, 1 each of Chronomaly/Harpie/Umbral Horror/Wind-Up; Hand-trap density: 11 copies (Ash 3, Ghost Ogre 3, Ghost Belle 3, Droll 2); Copy histogram: 7 singletons, 4 two-ofs, 13 three-ofs; Banlist status: Ash Blossom, Ghost Ogre, Ghost Belle, Droll (legal); Noroi (Forbidden); Called by Grave, Harpie's Feather Duster, K9-66a Jokul, Triple Tactics Talent, "A Case for K9" (Limited); No side deck: 0/15 cards
• Observed: Usage statistics show K9 archetype core at 36% inclusion (9/25 stat-tracked core cards present); Missing 7 mandatory Xyz per archetype stats (AA-ZEUS, Werewolf, C104, N.As.H., CXyz N.As.Ch., TY-PHON, another entry)
• Inferred: P(≥1 K9 starter in opening 5) ≈ 0.84 (hypergeometric, before Noroi removal: ~0.75 post-correction); Brick estimate ~15% (multiple Level 5 redundancy reduces hard-garnet risk; three-of concentration mitigates); Combo ceiling (best line) estimated ~74 before illegal removals, ~65 post-correction (Rank 5 Xyz + K9-17 Ripper searcher + negation layering); Combo median estimated ~55 (2–3 independent lines; starter diversity ~5–6 openers); Interruption resilience moderate (~40): Izuna/Jokul/Lantern provide route redundancy, but single Xyz destruction is a choke point; Resource economy net +1 to +2 per resolved line (float via searchers, Mulcharmy draw conversion); Interaction density ~3.2 per line (K9-17 Ripper + Disablaster + Arc Rebellion + scattered negation text); Going-second power ~52 (11 hand traps + 6 removal = 17 interaction cards; board-breaker coverage strong; no OTK setup limits closing); Offensive power limited (~35): max Xyz ATK 2600; missing Rank 9 (K9-X Ripper/M 3100) and Rank 12 (AA-ZEUS 3000) monsters; Main Deck efficiency poor (~28): 54 cards (bloat) + 13 three-ofs (redundancy) + 34 generic staples (purity 30%) compress flex slots; Extra Deck efficiency constrained (~30): legal max 15; this list runs 16 (violation); missing key Xyz leaves coverage gaps despite density; Pilotability moderate (~38): ~6–8 decision points per turn (Xyz pivots, searcher chains, hand-trap windows); moderate complexity, not FTK-level
• Provisional: Meta Power: null (no dated metagame sample supplied; archetype meta-share unknown); Tournament Reliability: ~22 (inferred from high hand-trap stability, no side deck, and combo-evidence gap; brick rate + post-side exposure lower confidence); Format fit: Provisional (K9 archetype meta-share absent; deck deviates from 36% core baseline; no tournament link)
• Data gaps: Deck is Illegal (Forbidden card + Extra Deck oversize) — no legal evaluation possible without correction No combo evidence: floor, median, ceiling, and per-starter breakdown all unknown; inferred from text only No tournament link: archetype meta-share, per-pilot match record, and format win-rate absent No guides data: archetype strategy intent unknown; builder rationale (Mulcharmy splash, 54-card main) not documented No side deck (0/15): best-of-3 adaptation strategy cannot be assessed No win-rate telemetry: brick rate, going-first/second performance, matchup spreads, and OTK frequency unknown Combo example boards absent: interaction density, resource signature, and resilience to single disruption are text-inferred, not verified
