K9 Deck #701092 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Board pressure from K9 and Vanquish Soul monsters (K9-17 Izuna, K9-66b Lantern, Vanquish Soul Heavy Borger, Vanquish Soul Caesar Valius) converted into Xyz/Link extra-deck attacks; no recorded boards to confirm the conversion.; Hand-trap-supported disruption (Ash Blossom, Ghost Belle, Nibiru, Droll & Lock Bird) that slows the opponent while the K9/Vanquish Soul engine develops.
• Turn 1 (going first): Open with Vanquish Soul and K9 searchers and a Normal Summon of a K9 monster without Tribute (requires opponent to hold 2+ cards), then extend into a Xyz or Link extra-deck monster; the T1 plan depends on an archetype starter being in the opening hand (about 0.91 at least one of 20 core cards in a 5-card hand, Inferred).
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Nibiru and Droll & Lock Bird to answer the opponent's first summon or search, then convert the surviving board into a Xyz or Link play.
• Recovery: Recycle through Mulcharmy Fuwalos and Mulcharmy Purulia draw effects and Vanquish Soul searchers, rebuilding hand size after an interruption.
• After siding: Not evaluable: the deck has no Side Deck (side_count 0), so no post-side plan exists.

Why it scores here

The deck's main engine (20 K9/Vanquish Soul core copies) has about a 0.91 chance of at least one copy in a 5-card opening hand, so it reliably opens a plan on paper. Conversion is the weak link: no parseable recorded boards exist, so the ceiling and median are text-only inferences and score low. Interaction is the strongest area, with 15 hand traps and 9 negation-text cards covering both going-first and going-second. The list is illegal (Forbidden K9-04 Noroi, Dimension Shifter and Saryuja Skull Dread, plus several cards over their copy limits), which caps the score; this is a structural read only. Popularity and archetype usage do not earn points, and the score was built from the system, not by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun secondary not blended, weights used as Midrange only. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); illegal list cap (-7). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 45.6, then modifiers -10 = 35.6, capped to 28 because the list is Illegal (theoretical/structural read only)

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

• Core archetype engine (K9 + Vanquish Soul) is reachable in most opening hands
• Large hand-trap and negation suite covers both turn orders
• Extra Deck carries 11 Xyz and 4 Link closers

Weaknesses

• Illegal list: three Forbidden cards and several copy-limit overages
• No recorded boards, so the conversion ceiling and median are unverified
• No Side Deck
• Low archetype purity (14%); many generic and tech slots dilute the engine

Critical choke points

• A single K9 or Vanquish Soul starter in hand is required for the line; without it the deck depends on generic draw
• Forbidden K9-04 Noroi and Saryuja Skull Dread are central pieces that cannot be legally run

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3 Forbidden cards and 7 over-limit entries; Main 55 / Extra 15 / Side 0 sizes are within format rules; Archetype purity 14.3%; composition counts
• Inferred: Archetype-core opening-hand probability about 0.91; Hand-trap interaction breadth; Engine accessibility and recovery estimates
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry for this deck Meta Power is Provisional unless a dated metagame sample is supplied
