K9 Deck #774305 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz and Link pressure from K9 and Vanquish Soul monsters (K9-17 Ripper, Rock of the Vanquisher, Vanquish Soul Caesar Valius, Heavy Borger, Lupis) built off a Vanquish Soul or K9 starter; Hand-trap-supported board preservation with Ash Blossom, Ghost Belle and Maxx "C" to protect the first summon
• Turn 1 (going first): Open a searcher (Vanquish Soul Dr. Mad Love, "A Case for K9", K9-17 Izuna, Mulcharmy Fuwalos) and hand-summon a Vanquish Soul or K9 monster, then Xyz or Link into a Vanquish Soul/K9 body
• Turn 2 (going second): Use Ash Blossom, Ghost Belle and Maxx "C" (six hand-trap copies) to interrupt the opponent's turn-1 board, then rebuild through hand-summons and Izuna or Jokul
• Recovery: Searcher density (16 cards) and Vanquish Soul hand-revival effects refill the hand; Stake your Soul! and Vanquish Soul, Start! provide a second route
• After siding: Not applicable: Master Duel ladder format has no side deck (side count 0)

Why it scores here

The deck reliably opens a functional plan: the archetype core is present in 26 cards (about 99.7% chance of at least one in a 5-card opening hand per the proxy), and 16 searcher-text cards give about 93.5% odds of at least one searcher in the opening hand. Its six hand-trap copies (Ash Blossom, Ghost Belle, Maxx "C") give interaction on the opponent's turn, which is where most of the score comes from, and the going-second hand-trap probability of about 65% supports that. Conversion into pressure relies on Xyz and Link extra-deck monsters, but with no recorded boards the ceiling and median are text-based inference and are scored conservatively. Popularity and the K9 usage stats confirm the list is real and accessible; they did not add points on their own, and the score is not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.7, Going First ≈ 58, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: banlist_exposure (-1); split_archetype_engine (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta null/provisional)

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

• Archetype core and searchers are redundant, so the opening hand is rarely dead
• Six hand-traps give going-second interaction and protection for the first summon
• Strong board-breaking and attacking Extra Deck options (Ripper, Rock, Valius, Borger, Dogoran)

Weaknesses

• Two archetype engines (K9 and Vanquish Soul) dilute exact-name coherence
• Hand-summon and revival conditions raise sequencing complexity
• No recorded board data to confirm the ceiling

Critical choke points

• Turn-1 hand-trap or starter-summon sequencing when the opponent holds a hand-trap of their own
• Dependence on the Vanquish Soul/K9 monster in hand for Special Summon routes

Recommended changes

Evidence & confidence

• Verified: Legal main 40 / extra 15 / side 0 for Master Duel (size rules 40-60 / 0-15); All five restricted cards run at their legal copy limits; Archetype composition and copy histogram from the deck list; Card text for the cards listed in evidence
• Observed: Archetype usage stats: K9 core inclusion rates and typical copies
• Inferred: Opening-hand consistency from hypergeometric odds; Going-second hand-trap odds; Ceiling and interaction read from card text; Going-first/second power estimates
• Provisional: Meta power (no dated sample); Matchup and format fit (no tournament link); Side adaptability (no side in Master Duel)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first/second, matchup and brick rates are Inferred Meta Power is provisional unless a dated metagame sample is supplied
