K9 Deck #772321 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: K9 and Cyber Dragon boards with Chimeratech and Link/Xyz finishers, supported by Bystial and Cyberdark extenders (theoretical, not verified by combo data); Non-engine beatdown from Nibiru, Chaos Angel and Bystial bodies after interaction clears the way
• Turn 1 (going first): Open a searcher or Cyber Dragon starter, hold Ash Blossom / Infinite Impermanence / Droll as hand interaction, and extend through K9 Normal Summons
• Turn 2 (going second): Use hand traps (Ash, Droll, Ghost Belle, Ghost Ogre) to answer the opponent's first summon, then reach a K9 or Cyber Dragon board from the remaining hand
• Recovery: Recover through Cyberdark Claw, Mulcharmy draw effects and Cyber Dragon Herz / Nachster searches from the Deck and GY
• After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists in the evidence

Why it scores here

The deck's score comes from the system it forms, not from averaging its card scores. Its interaction suite (Ash Blossom, Droll & Lock Bird, Infinite Impermanence, Ghost Belle, Ghost Ogre, Lightning Storm, Harpie's Feather Duster) gives a good chance of answering a first summon or a set backrow, and the searchers and hand traps keep it from stalling badly. The K9 core is present at 53% of the archetype's standard core cards, and only 11.4% of the Main Deck uses the exact K9 archetype name, so the engine is split across Cyber Dragon, Cyberdark, Mulcharmy and other sub-archetypes; that split costs points on conversion and consistency. No recorded boards exist, so the combo ceiling and median are text-based inferences and stay low. Popularity was not a factor, and the score is capped because the list is illegal: three copies of two Semi-Limited cards plus an unresolved passcode.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary weights not applied; Midrange profile used as-is. Structural ≈ 53, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_and_copy_limit_violation (-10); no Side Deck (-2). Final formula: Illegal: theoretical/structural-only. Formula 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*53 + 0.20*40 - 12 = 38.4, capped to 30 by the illegal-deck rule. Meta Power is null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.75 · 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 hand-trap and negation suite (14 hand traps, 14 negation-text cards)
• Multiple searchers (21 searcher-text cards) give consistent access to key pieces
• Several high-ATK Extra Deck and Main Deck finishers (Chaos Angel, Nibiru, Bystial)

Weaknesses

• Illegal as built: two cards at 3 copies where OCG limit is 2
• Split engine: only 11.4% exact-name K9 purity across Cyber Dragon, Cyberdark, Mulcharmy and others
• No Side Deck, so no post-side plan
• Unresolved passcode in the Main Deck means the list cannot be fully verified

Critical choke points

• Reliance on Ash Blossom / Droll-style interaction to answer the opponent's first summon
• Dependence on the K9 archetype core (K9-66a Jokul, K9-66b Lantern, Lupis) that is only partly present

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom and K9-17 Izuna at 3 copies, legal limit 2; Main 56 / Extra 14 / Side 0 counts within OCG size rules (Main 40-60, Extra 0-15); Archetype core inclusion 74.8% in hand 5 (hypergeometric); Card stats for Nibiru, Chaos Angel, Bystial Druiswurm, Bystial Magnamhut
• Inferred: Engine consistency P(starter) and brick estimates; Interaction quality from card text; Going-second and going-first estimates
• Provisional: Meta Power null; matchup fit D13 without a dated sample
• 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 One passcode (10443957) in CardIDList could not be resolved and was counted as Main No win-rate telemetry exists, so going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
