K9 Deck #773433 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Tempo
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Level 5 Vanquish Soul and K9 board pressure converted by high-ATK extra-deck boss monsters (Caesar Valius 3000, K9-X Werewolf 3300, K9-X Ripper/M 3100, Arc Rebellion 3000); Xyz and Link extra-deck pressure from Jacks, Ripper and Rock of the Vanquisher, plus hand-trap disruption of opposing lines
• Turn 1 (going first): Open on a searcher (Vanquish Soul Start, A Case for K9, K9-66a Jokul or Lantern) and a Level 5 starter, then convert through a Xyz or Vanquish Soul revival (Inferred)
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Maxx C, Droll and Lock Bird) to break the opponent's first line, then rebuild through searchers and K9 summons (Inferred)
• Recovery: Recover through Vanquish Soul hand-revealing effects and K9 Forced Release or Noroi re-summons from the Graveyard (Inferred from card text)
• After siding: No side deck is registered, so no post-side plan exists in the export

Why it scores here

The deck reliably opens a functional starter: the hypergeometric estimate gives about a 92% chance of at least one searcher in a 5-card opening hand, and the 15 searcher-text cards make the first line dependable (Inferred). Its conversion is judged on the system, not on the average of its cards: two sub-engines (Vanquish Soul and K9) share the Level 5 and DARK/EARTH/FIRE space and create some conflict, which is why the score is capped near the mid-60s. Interruption resilience is supported by 7 hand traps (about 71% to have one in a 6-card going-second hand) and by Graveyard recovery through K9 and Vanquish Soul effects. No combo boards, tournament link, or meta sample were supplied, so the ceiling and floor are text-only inferences and Meta Power stays null. Popularity was not credited: the archetype usage data confirms a real list but does not raise the score, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Balanced (D13 dropped and renormalized over 93, since no meta sample exists). Structural ≈ 61.7, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: engine conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, D13 dropped, renormalized): 0.80*61.7 + 0.20*56 - 3 = 57.6 -> 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Dense searcher density (15 searcher-text cards) gives a reliable first line
• Seven hand traps give strong going-second interaction
• Several 2500-3300 ATK bosses and removal support closing

Weaknesses

• Two sub-archetypes share the Level 5 and attribute space, creating engine conflict
• No side deck registered
• Extra Deck Xyz requirements limit access to some bosses

Critical choke points

• Level 5 monster access for both K9 and Vanquish Soul lines
• Single-copy staples such as Vanquish Soul Start and Reinforcement of the Army are not redundant

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel with 40 main and 15 extra, 0 side; All restricted cards run within legal copy limits; Copy histogram sums to 40 main and 15 extra
• Inferred: Searcher and hand-trap hypergeometric consistency estimates; Engine conflict between Vanquish Soul and K9; Going-second hand-trap density
• Provisional: Matchup and format fit (no dated meta); Side deck adaptability (no side deck)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent usage statistics in this deck flags disagree with the cards array for several Extra Deck cards (Werewolf, Jacks, Ripper, Number 104, Umbral Horror Masquerade); the cards array was trusted no side deck registered no win-rate telemetry exists in YGOVN — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
