K9 Deck #765109 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz and Link beatsticks (K9-X Werewolf, K9-X Ripper/M, Vanquish Soul Caesar Valius, K9-66X Jacks) reached through hand-starter chains of K9 and Vanquish Soul Level 5 monsters; Piercing and direct damage from Ripper/M and the Vanquish Soul Stake and Snow Devil damage effects
• Turn 1 (going first): Open a Vanquish Soul or K9 hand starter, use Normal Summon without tribute or Special Summon from hand to reach a Level 5 Xyz, and hold 1 or 2 hand traps for the opponent's first activation
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash Blossom, Infinite Impermanence, Ghost Ogre, Droll and Lock Bird, Maxx C) to stop the opponent's starter, then rebuild the board through K9 and Vanquish Soul summons
• Recovery: Searchers (Vanquish Soul Dr. Mad Love, K9 A Case, Vanquish Soul Start, Razen) plus Mulcharmy draw and K9-X Forced Release refill the hand and reconstitute an Xyz after a board wipe
• After siding: No side deck is registered (side_count 0); post-side plan is not applicable in this format and no sideboard evidence exists

Why it scores here

The deck reliably opens a functional starter: the archetype-core group of 28 copies gives about 0.998 probability of at least one core card in a 5-card opening hand, and 15 searcher-text cards give about 0.91 (Inferred, hypergeometric). Interaction is layered across 11 hand traps, 6 negation-text cards and 8 removal-text cards, so the deck can keep a line alive through a common disruption. Its ceiling is high with multiple Level 9 and 5 Xyz beatsticks, but no recorded boards exist, so floor and median are text-based estimates and carry a wide band. Popularity and archetype usage were not credited; the score comes from the consistency, resilience and interaction of the system, not from an average of card scores. Side deck, matchup fit and Meta Power are provisional or absent in the evidence.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun secondary noted, not blended numerically. Structural ≈ 67.6, Going First ≈ 70, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: engine conflicts (-2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*67.6 + 0.20*62 = 66.5, then context modifiers -3 = 63

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• Core starter access is near-certain in a 5-card hand (about 0.998) with redundant K9 and Vanquish Soul routes
• 11 hand traps plus negation and removal text layer interaction on both turns
• Extra Deck is fully used with Xyz and Link threats of 2600 to 3300 ATK
• Searcher density (15 cards) supports recovery after disruption

Weaknesses

• No recorded boards: floor, median and ceiling are text-based and unverified
• Two Level 5 hand-starter families compete for the same hand slots and attribute reveals
• Hand-trap-heavy main deck risks dead cards when the opponent presents no target
• No sideboard, so post-side adaptability is absent

Critical choke points

• Single-copy Limited cards (Maxx C, Reinforcement of the Army, Stake your Soul!) are one-of lines with no backup
• Turn-1 starter must be a hand card with a Level 5 or Attribute reveal; a hand without any K9 or Vanquish Soul monster stalls the line

Evidence & confidence

• Verified: Legal status; 41 main, 15 extra, 0 side; all restricted cards within legal copy limits; Card stats and text for all 38 distinct cards in the cards array; Hypergeometric probabilities as reported in the evidence
• Observed: No observed boards: combos_evidence total_combos 0
• Inferred: Starter and searcher consistency from probabilities block; Hand-trap interaction density and going-second plan; Recovery and resource economy from text; Ceiling from text, not measured
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (no tournament context); Side deck adaptability (no sideboard)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry for going-first, going-second, matchup, brick or starter rates Meta Power provisional without dated metagame sample usage_statistics in_this_deck flags disagree with cards[]: Ripper, Werewolf, Jacks, TY-PHON, Rock of the Vanquisher, Masquerade, Saryuja and S:P Little Knight are listed as absent but appear in cards[]; cards[] was used as source of truth no sideboard registered, so side-deck scoring is structural only
