K9 Deck #772333 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

Main 43 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: K9 and Vanquish Soul Xyz/Link boards (K9-X Ripper/M, K9-66X Jacks, Caesar Valius, Jiaolong) pressuring through hand-trap-protected lines; Ripper and Masquerade interaction on the opponent's effect activations, with Ripper/M piercing
• Turn 1 (going first): Open a Vanquish Soul or K9 starter (Stake your Soul!, Vanquish Soul Dr. Mad Love, K9-66b Lantern) with a searcher, then extend into a Xyz; hold Ash, Ghost Ogre or Infinite Impermanence for the opponent's first response
• Turn 2 (going second): Hand-trap the opponent's first activation (Ash, Ghost Ogre, Infinite Impermanence, Izuna's Quick Effect on monster effects), then convert the survivor into a Xyz board
• Recovery: Searchers (A Case for K9, K9-66a Jokul, Vanquish Soul, Start!) and Vanquish Soul revival through Stake your Soul! and Heavy Borger rebuild the hand; Ripper recovers via its search effect
• After siding: Not evaluable: the deck runs no side deck, so no post-side plan exists

Why it scores here

This deck is Illegal: three copy-limit violations (Ash Blossom, Vanquish Soul Razen, K9-17 Izuna) and no side deck. Its structural read is Midrange with a Stun secondary, built on a 15-copy archetype core (about 0.90 chance of at least one core card in a 5-card opening hand) and nine hand traps (about 0.78 chance of at least one in a 6-card hand when going second). Interaction and going-second pressure are its strongest areas, backed by Ripper/M, Jacks and Masquerade on the extra-deck side. Floor and median output cannot be measured because no boards were supplied, so both are text-only inference. Popularity in the K9 archetype and the usage statistics confirm the list is real, but they do not add points to the score, and no card scores were averaged. The structural score is about 55 and the theoretical final is about 41; the Illegal status caps the published score at 30.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, with Stun secondary used only for the hand-trap context (structural weights unchanged; blend disclosed, not applied). Structural ≈ 55, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Copy-limit violations (illegal) (-12). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53; modifiers total -12 gives 41 theoretical; Illegal status caps the published score at 30 (structural-only, no normal Final score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• Large archetype core: 15 K9 or Vanquish Soul copies with about 0.90 chance of a core card in a 5-card opening hand
• Dense interaction: nine hand traps plus negation and removal text, with about 0.78 chance of a hand trap in a 6-card going-second hand
• Searcher density (15) and revival lines keep the hand refueling after one disruption

Weaknesses

• Illegal as listed: Ash Blossom, Vanquish Soul Razen and K9-17 Izuna are over their copy limits
• No side deck, so there is no best-of-3 adaptation
• Tech-heavy main (13 tech) dilutes the engine and raises the brick rate
• Two-archetype engine (K9 and Vanquish Soul) with a low exact-name purity (22.8%)

Critical choke points

• Each K9 and Vanquish Soul starter needs a specific Attribute or Level match to reveal and summon
• Ash and Izuna both sit in the hand-trap package; cutting them to legal counts removes two of the main interaction routes

Recommended changes

Evidence & confidence

• Verified: Main deck 43 cards and extra deck 14 cards (within 40-60 and 0-15 size rules); Copy-limit violations: Ash Blossom x3 (legal 2), Vanquish Soul Razen x3 (legal 1), K9-17 Izuna x3 (legal 2); Banlist tokens for Limited and Semi-Limited cards on the deck as listed; Card stats and types from the card table; Archetype core inclusion 50.8 to 85.5 percent from usage statistics
• Observed: Usage statistics show the core K9 cards at 50 to 85 percent inclusion (archetype-wide rates, not this deck's results)
• Inferred: Opening-hand consistency (0.90 core, 0.78 hand trap) from hypergeometric estimates; Hand-trap and searcher roles from card text; Structural score 55 and theoretical final 41 from the rubric weights; Going-second and going-first estimates from interaction density in the text
• Provisional: Meta power (null) and format fit (D13) because no dated metagame sample is supplied
• 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 absent No win-rate telemetry exists in YGOVN (going-first and going-second, matchup, brick and starter rates); those signals are Inferred or Unknown No side deck; post-side plan and D12 cannot be scored from data Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
