K9 Deck #750783 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz and Link boards from K9 and Vanquish Soul starters (K9-X Werewolf and K9-66X Jacks are not in the list; Number and Vanquish Soul Link boards carry the pressure); Vanquish Soul Caesar Valius and Heavy Borger as large Main Deck beaters
• Turn 1 (going first): Open on K9 and Vanquish Soul searchers (Dr. Mad Love, Razen, Jiaolong, A Case for K9), go to Xyz or Link, and protect with Ash Blossom and Maxx C
• Turn 2 (going second): Hand traps (Ash Blossom, Droll and Lock Bird, Maxx C, the Forbidden Dimension Shifter) plus Normal Summoned K9 monsters to contest the board
• Recovery: Rebuild from the 17 searcher-text cards and the Vanquish Soul revive loop (Stake your Soul, Vanquish Soul Start)
• After siding: No Side Deck is registered (0 cards), so no post-side plan exists in this list

Why it scores here

The deck reliably reaches a live engine on the opening hand: the 25-copy archetype core has a hypergeometric P(at least one in a 5-card hand) of about 0.995, and 17 searcher-text cards add redundancy. Its interaction suite is layered, with Ash Blossom, Droll and Lock Bird, Maxx C and removal text on Vanquish Soul and K9 monsters, which supports the structural score on interaction and resilience. The score is pulled down by two engines that share few cards (K9 16 copies, Vanquish Soul 18 copies, exact-name purity 29.1 percent), by no recorded boards (combo ceiling and median are text-only inference), and by a Forbidden card run at 1 copy, which makes the list illegal as built. Popularity and archetype usage do not earn points here, and the score was not built by averaging the individual card scores; the Illegal status caps the Final score at 35 and it is theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (Forbidden card in list) (-10); engine conflict (-4). Final formula: Structural 56.8 (Midrange profile) → 0.80*56.8 + 0.20*48 = 55.2, then -14 modifiers = 41.2, then Illegal cap applied → 35 (theoretical/structural-only, no normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core present in almost every opening hand
• Layered hand-trap and removal-text interaction
• Redundant searchers (17 searcher-text cards)

Weaknesses

• Two engines (K9 and Vanquish Soul) with low exact-name purity (29.1 percent)
• Forbidden Dimension Shifter run at 1 copy, so the list is illegal
• No Side Deck, so no post-side adaptation
• Two core Extra cards (K9-X Werewolf, K9-66X Jacks) are not run, while off-archetype Extra slots are used

Critical choke points

• Dimension Shifter must come out before the list is playable
• Extra-Deck slots are full (15/15), so any core swap has to remove an off-plan Extra card

Recommended changes

Evidence & confidence

• Verified: Dimension Shifter is Forbidden and run at 1 copy (legality); Main 40 and Extra 15 meet the master-duel size rules; K9-X Werewolf and K9-66X Jacks are 100 percent archetype core and not in the list; Archetype purity is 29.1 percent exact-name
• Inferred: Opening-hand consistency from hypergeometric probabilities; Brick and conflict estimates; Interaction density from text hints; Going-first and going-second estimates
• Provisional: Meta power (no dated sample); Matchup fit and side adaptability (no data)
• 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 records are absent no win-rate telemetry, so going-first, going-second and matchup rates are unknown deck title is null no Side Deck registered Meta Power is provisional unless a dated metagame sample is supplied
