K9 Deck #770599 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Stun
• Format: tcg

Legality

Main 47 / Extra 20 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Xyz pressure from K9 Xyz monsters (K9-X Ripper, K9-66X Jacks, K9-X Werewolf is not run) backed by Number-series and Link boards in the Extra Deck; Disruption-led attrition: hand traps and Xyz-material negation grind the opponent while the Dark Time Wizard engine supplies bodies
• Turn 1 (going first): Open a searcher (Alligator's Dragon Knight, Dark Time Wizard, K9-66a Jokul or A Case for K9) to reach a K9 Xyz, then hold Ash Blossom and Droll for the opponent's first activation
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit) to answer the opponent's board, then Xyz into a 2000+ ATK K9 on the next turn
• Recovery: Rebuild from Dark Time Wizard and Foolish Graverobber recursion plus K9-X Forced Release to re-Xyz from the Extra Deck
• After siding: Not evaluable: the deck runs no Side Deck (0 cards) and best-of-3 side plans cannot be assessed

Why it scores here

The deck reliably finds a starter: the K9 core group gives about 0.91 odds of at least one core card in a 5-card opening hand and the searcher group about 0.89 (Inferred from hypergeometric estimates). Its interaction suite (Ash Blossom, Droll and Lock Bird, Ghost Ogre and Snow Rabbit, plus Xyz-material negation from Number 104 and Number C104) gives it breadth against the opponent's board, which supports the Midrange profile. Conversion to pressure runs through K9 Xyz monsters and Number-series boards, but no recorded combos exist, so ceiling and median are text-only reads with low confidence. The deck is illegal in the TCG format: it runs three copies each of two Semi-Limited cards, two copies of a Limited card, one copy of a Forbidden card, and an Extra Deck of 20 against a maximum of 15. Under the rubric this caps the score as a theoretical, structural-only read. Popularity did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun-leaning interaction read as a qualitative secondary; no weights changed. Structural ≈ 54.6, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); dependence on Extra Deck Xyz (-2). Final formula: Illegal list: theoretical cap. Uncapped 0.80*54.6 + 0.20*40 + modifiers (-8) is about 45; capped to 25 for the TCG legality violations. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• Searcher density (16) and the K9 core group make a starter likely in the opening hand
• Six hand traps and Xyz-material negation give layered interaction against both turns
• K9 Xyz and Number-series end-boards reach 2500 to 3000 ATK

Weaknesses

• Illegal in TCG: copy-limit violations on four cards and an Extra Deck of 20 against a limit of 15
• Low exact-archetype purity (17.9%) means many dead or redundant cards in hand
• No Side Deck, so no best-of-3 adaptation
• No recorded combos, so ceiling and median are unverified

Critical choke points

• K9 Xyz monsters require a Level 5 or matching material base; a hand without a searcher or core starter stalls
• Forbidden and Limited restrictions remove pieces that a legal list would need to replace

Recommended changes

Evidence & confidence

• Verified: Main 47 (within 40-60), Extra 20 (over 15), Side 0; Copy-limit violations on Ash Blossom, K9-17 Izuna, Droll and Lock Bird, Called by the Grave; Exact-name K9 purity 17.9%; archetype core copies 17 in the Main Deck
• Observed: K9 core inclusion across the 20 archetype stat rows (K9-17 Izuna 93%, Ash Blossom 97%)
• Inferred: Starter access about 0.91 and searcher access about 0.89 from hypergeometric estimates; Interaction breadth from card text (Ash Blossom, Droll, Ghost Ogre, Number 104, Number C104); Midrange strategy classification from text and composition
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• 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 are absent No win-rate telemetry; going-first, going-second and matchup rates are unknown No Side Deck registered; post-side plan cannot be assessed Meta Power is provisional without a dated metagame sample
