K9 Deck #730290 — Yu-Gi-Oh! OCG

K9 Hybrid — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±5 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Blind-Second
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Xyz-based board pressure via K9 and Vanquish Soul attribute-reveal chains; Grind game through Mulcharmy draw triggers and floodgate stacking
• Turn 1 (going first): Open with Level 5 starter, reveal attribute to chain searches, build Xyz + Link board with 2–4 interaction points (negation + floodgate)
• Turn 2 (going second): Hand-trap (Ash/Impermanence/Nibiru) into opponent's setup, break board, recover via Mulcharmy draws, rebuild Xyz and close
• Recovery: Redundant Level 5 starters (6 distinct), GY recursion (Lantern K9 SS, Caesar Valius return), searcher density (20 copies) enables finding payoffs
• After siding: Unknown (no side cards supplied; likely meta-reactive floodgate/removal shifts)

Why it scores here

This K9-Vanquish Soul hybrid opens a functional Xyz board with solid consistency (78% to draw a Level 5 starter, 91% to draw a searcher), but the 55-card main dilutes variance and reduces reliability compared to optimized 40-card lists. The deck produces decent combo ceilings (2–4 Xyz/Link + negation) and has strong redundancy (6 distinct Level 5 starters) that survives disruption, though missing key powerhouses like K9-X Werewolf and Divine Arsenal AA-ZEUS limits end-board ceiling and going-second board-wipe capability. The 75% hand-trap rate and floodgate stacking (Dimensional Fissure, Dimension Shifter) provide solid going-second interaction, but without measured combo boards, the system-level power (combo floor, resource flow, board interaction density) cannot be verified—only inferred from card roles and text. The score reflects a **playable, mid-tier variant** that sacrifices a few core Extra-Deck slots and consistency optimizations for technical coherence, not a structural flaw.

Dimension scores

How the score was computed

Strategy profile: 80% Combo, 20% Midrange. Structural ≈ 70, Going First ≈ 67, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 61. Modifiers: 55-card main deck dilution (-2); Missing tier-1 Extra-Deck cards (-2); K9-Vanquish Soul hybrid archetype fit (-1); High searcher density enablement (1). Final formula: 0.80 * Structural (70) + 0.20 * TournamentReliability (61) = 64 (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ 0.61 · 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

• Very high starter redundancy (6 distinct Level 5 monsters) ensures consistency and resilience to disruption
• Strong hand-trap density (11 copies, 75.6% opening rate going-second) enables board breaking and going-second viability
• Searcher suite (20 copies) provides flexibility and recovery after whiffs or disruption
• Dual-engine (K9 + Vanquish Soul) offers coherent synergy and attribute-based utility (reveal triggers, Xyz overlays)
• Floodgate diversity (Dimensional Fissure, Dimension Shifter, Droll & Lock Bird) disrupts GY-centric and search-heavy decks

Weaknesses

• 55-card main deck (non-standard for OCG) dilutes startup consistency vs 40-card optimized peers; ~21.5% brick rate on core
• Missing three tier-1 Extra-Deck cards (K9-X Werewolf 68.8%, K9-17 Ripper 55.8%, Divine Arsenal AA-ZEUS 57.1%) limits combo ceiling and going-second board wipe
• No measured combo data; floor/median/ceiling and system-level board power unverified (all inferred from text and role tags)
• Mulcharmy soft starters require clear board and opponent summon to activate draw; weak opening T1 setup liability
• Conflicting Level 5 normal summons (Izuna, Lantern, Jokul) cause redundant hands with only one summonable

Critical choke points

• Lack of measured combo lines: without boards, cannot confirm independent routes through disruption or verify actual resource flow
• No side deck: cannot assess best-of-3 adaptability or post-side stability
• Missing K9-17 Ripper: eliminates on-board Xyz negation on opponent monster effects (hand/GY activation)
• Mulcharmy dependency: Fuwalos and Meowls require opponent to have already summoned before their draw triggers activate
• No direct damage or OTK engine: forced into grind game against resilient boards; limited closing speed

Evidence & confidence

• Verified: Legality: 55 main / 15 extra / 0 side within OCG size rules; all 11 restricted cards at legal copies; Card text: all 44 distinct main cards and 14 Extra cards resolved with description excerpts; Banlist status: 10 Limited, 1 Semi-Limited (Droll & Lock Bird ×2); all legal under OCG rules; Archetype classification: K9 primary, Vanquish Soul secondary (21 copies), Mulcharmy tertiary
• Observed: Usage statistics: K9 archetype core card inclusion rates (Jokul 74%, Lupis 72.7%, Izuna 58.4%); this deck runs 7/15 core cards (46.7%); Hand trap draw probability: 11 hand-trap copies, P(≥1 in opening 6) ≈ 0.7565 going-second per hypergeometric calculation
• Inferred: Engine consistency: P(≥1 core starter in opening 5) ≈ 0.7846 from hypergeometric; 72 accessibility score; Brick rate: 21.5% full core no-draw (P(no core)) from hypergeometric; contributes to 66 brick management score; Combo ceiling and floor: inferred from 10 Level 5 starters + searcher chains, but without measured boards = 65/62 scores unverified; Interruption resilience: 6 distinct Level 5 starters + 3 GY recursion paths confirm redundancy, but independent line count unverified (D5 = 68); Resource economy: Mulcharmy x2 + spell draw engines estimated to generate 2–4 cards per grind turn, but ResourceScore field absent (D6 = 64); Board interaction: 8 negation-text + 3 floodgate cards estimated at 3–4 interaction points per opening, but average interaction density unavailable (D7 = 70); Going-second power: 75.6% hand-trap rate + 11 total copies supports 68 score; missing board-wipe cap explains gap (D8 = 69); Offensive closing: 2600–3000 ATK beater range typical; missing Werewolf multi-attack caps ceiling at 61 (D9 = 61); Main deck efficiency: 55-card size penalty (−3 vs 40-card) drives D10 = 62; 20 searchers mitigate dilution partially; Extra deck efficiency: 14/15 filled, 11 Xyz strong, but 3 missing tier-1 cards (Werewolf, Ripper, AA-ZEUS) cap D11 = 68; Pilotability: 6+ starters reduce opening error punishment, moderate complexity (reveal + timing); D14 = 67 estimate
• Provisional: Meta Power: null — no dated metagame sample supplied; archetype meta-share unavailable; cannot assess top-deck positioning; D13 Matchup fit: 55 — K9 is real OCG archetype, but deck is non-core variant; without meta context, rated neutral
• Data gaps: No combo boards: cannot verify combo ceiling (D3), floor (D4), median output (D4), power distribution, or interaction density (D7); all text-only inferred No tournament link: no archetype meta-share, per-pilot match record, or dated metagame sample; Meta Power remains provisional No win-rate telemetry: brick rate (21.5% estimated only), OTK rate, going-first/second performance, matchup spreads unknown No side deck: 0 side cards supplied; D12 cannot be validated; best-of-3 adaptability unknown No ResourceScore/netCardAdvantage field: resource economy (D6) cannot be measured; only card-count inference available No average interaction density: board quality (D7) cannot be confirmed from measured boards; text-role tag inference only No going-second board split: cannot compare T1 vs T2 power distribution across the deck's play patterns
