K9 Deck #773043 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Board pressure from K9 and Vanquish Soul Extra Deck monsters (K9-X Jacks, Vanquish Soul Caesar Valius, Umbral Horror Masquerade, K9-ØØ Lupis) backed by searcher-driven setup; Vanquish Soul Rocks and Arc Rebellion Xyz Dragon as Extra Deck closers once the board is established
• Turn 1 (going first): Normal Summon K9 or Vanquish Soul monsters that search (Vanquish Soul Dr. Mad Love, Vanquish Soul Razen, K9-66b Lantern), use Stake your Soul! or Vanquish Soul, Start! to access a second attribute-matched monster, then Xyz Summon from the Extra Deck
• Turn 2 (going second): Hold Ash Blossom & Joyous Spring, Ghost Belle & Haunted Mansion, and Droll & Lock Bird to answer the opponent's first searches or summons, then rebuild the board through Vanquish Soul revive-by-return effects
• Recovery: Searchers (Vanquish Soul, Start!, A Case for K9, Reinforcement of the Army) and Pot of Prosperity recover cards from the Deck; K9-66b Lantern and K9-66a Jokul self-revive K9 Level 5 monsters from the GY
• After siding: Not evaluable: no side deck is supplied, so no post-side plan can be scored

Why it scores here

The deck's consistency rests on a dense searcher layer: 19 searcher-text cards give about 0.97 probability of at least one searcher in a 5-card opening hand, and 14 K9 cards give about 0.90 probability of at least one core card opening, so the engine usually comes online by turn 2 (Inferred). Interaction is the strongest system feature: three copies of Ash Blossom, two Ghost Belle, one Droll & Lock Bird and Number C104 give about 0.65 probability of a hand trap in a 6-card going-second hand (Inferred), which supports the going-second score. Floor and ceiling could not be measured because the export contains no recorded combos, so the combo dimensions are text-based estimates and carry low weight. The score was not reached by averaging card scores or by the archetype's popularity (usage stats show only 61.5% core presence and an exact-name purity of 23.6%), and the illegal copy counts cap the final score at 35 regardless of the structural read.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary; Toolbox weights were not applied separately, the Midrange profile was used as the structural base. Structural ≈ 58, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: No reliable metagame: 0.80*Structural(58) + 0.20*TournamentReliability(52) = 57 uncapped; Illegal list capped to 35 under rubric Step 2 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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 layer gives a high chance of a functional opening hand
• Layered interaction from hand traps and negation text
• Multiple end-board threats in the Extra Deck with independent routes

Weaknesses

• Three cards exceed their copy limits, so the list is illegal as built
• No side deck, so no post-side adaptability
• Low exact-archetype purity (23.6%) suggests a loose engine with Vanquish Soul and generic staples

Critical choke points

• Vanquish Soul Razen (1 legal copy) is a Limited searcher; losing it to a Limited-compliant build removes a key search route
• K9 Level 5 monsters must be live for the K9 Xyz plan, so a single hand-trap answer can stall the engine

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15, legal on size; Three over-limit copies (Ash Blossom, Vanquish Soul Razen, K9-17 Izuna) against banlist limits; Card text and stats from the resolved card list; Usage stats show 61.5% core presence
• Inferred: Hypergeometric opening-hand probabilities for searchers, core K9 and hand traps; Interaction density from negation and removal text; Going-second hand-trap estimate
• Provisional: Median combo output and meta matchup fit; Post-side adaptability
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry in YGOVN for going-first, going-second or matchups Side deck is empty, so post-side plan is unevaluated Meta Power is provisional without a dated metagame sample
