K9 Deck #750703 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Vanquish Soul and K9 Xyz/Link boards: Vanquish Soul Caesar Valius, Heavy Borger and Jiaolong pressure, converted through K9-66X Jacks, K9-X Forced Release and Divine Arsenal-style Xyz lines (text-only read, no recorded boards); Hand-trap-supported disruption into Xyz/Link extra-deck summons (Ash Blossom, Maxx C, Vanquish Soul Hollie Sue control steal)
• Turn 1 (going first): Open on a Vanquish Soul or K9 starter, search a second Vanquish/K9 piece (Vanquish Soul Start, Dr. Mad Love, A Case for K9), and Normal Summon K9 monsters without Tribute when the opponent holds 2+ cards
• Turn 2 (going second): Hold Ash Blossom, Maxx C and Vanquish Soul Hollie Sue for the opponent's first summon or starter, then rebuild the board from hand-revive and searchers
• Recovery: Vanquish Soul revive effects from hand (Hollie Sue, Jiaolong, Heavy Borger) plus K9 searches rebuild a board after one interruption; Mulcharmy draw effects add card flow
• 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 is Illegal: Dimension Shifter is Forbidden in master-duel and is run once, so the Final score is capped and the evaluation is structural-only. Structurally it is a K9 and Vanquish Soul hybrid whose core cards are present at 3 copies, with the archetype core group giving about 99% chance of at least one core card in a 5-card opening hand (Inferred). Its searcher density (15 searcher-text cards, about 92% chance of one in hand) and five hand traps give it a reasonable opening and interruption profile. The score does not come from popularity or meta-share, which are absent here, and it does not average the individual card scores; it reflects the system's consistency and disruption read. The Xyz and Link extra-deck coverage is broad, but with no recorded boards the conversion ceiling and median are text-only inferences and are weakly supported. The deck has no Side Deck, so post-side adaptability is minimal.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8); no side deck (-2); engine split (-2). Final formula: Illegal cap: 0.80*Structural(57) + 0.20*TournamentReliability(50) = 55.6; modifiers -12 gives 43.6; capped to 30 for an Illegal deck (structural-only, no normal Final score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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 cards at 3 copies give high opening access
• Dense searcher text (15 cards) supports consistent T1-T2 starts
• Five hand traps and hand-revive effects give several interruption routes
• Broad Xyz/Link extra-deck coverage

Weaknesses

• Illegal: Dimension Shifter is Forbidden in master-duel
• Mixed sub-archetype engine (Vanquish Soul, K9, Mulcharmy, splash) with only 25.5% exact-name purity
• No recorded boards, so combo conversion and median output are unmeasured
• No Side Deck, so no post-side plan

Critical choke points

• Dimension Shifter must be removed before the deck is legal to play
• Single-copy K9-X Forced Release and Stake your Soul are the only ways to access some engine steps; losing them removes a route

Recommended changes

Evidence & confidence

• Verified: Dimension Shifter is Forbidden in master-duel, 1 copy run (illegal); Main 40 and Extra 15 are within the master-duel size rules; Exact-name purity 25.5% and archetype spread from composition; Card text for all 40 Main and 15 Extra cards from the evidence pack
• Inferred: Core-group and searcher hypergeometric estimates; Hand-trap going-second estimate; D1-D14 dimension scores from text and composition; Structural score from the Midrange profile
• Provisional: Meta power (null, no dated metagame sample); Matchup fit and tournament reliability (no tournament link); Side-deck adaptability (no Side Deck)
• Data gaps: Illegal list: Final score capped; the evaluation is structural-only No combos supplied: combo floor, median and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot record are absent No win-rate or brick telemetry in YGOVN; brick and starter rates are Inferred No Side Deck in the export Meta power is Provisional without a dated metagame sample
