K9 Deck #756569 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±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: Vanquish Soul and K9 Xyz/Link boards (Caesar Valius, Heavy Borger, TY-PHON Sky Crisis, Jacks, AA-ZEUS, Vanquish Soul Rocks) reached through searcher-driven summons; Vanquish Soul Hollie Sue / Dr. Mad Love / Jiaolong pressure and Retaliating C / Maxx C disruption into a board
• Turn 1 (going first): Open on a searcher-enabled Normal Summon (K9-17 Izuna or Vanquish Soul Dr. Mad Love / Razen), search a second engine piece, then build an Xyz or Link extension line (Inferred from card text, no recorded boards)
• Turn 2 (going second): Use Ash Blossom / Maxx C / Dimension Shifter (illegal) hand traps against the opponent's first summon, then Special Summon from hand into a Xyz line (Inferred from card text)
• Recovery: Vanquish Soul and K9 searchers (Razen, A Case for K9, Vanquish Soul Start!) rebuild the hand from the Deck; Mulcharmy draw effects refill when the board is empty (Inferred)
• After siding: Not defined: the list has 0 side-deck cards, so there is no post-side plan

Why it scores here

The list is Illegal in Master Duel because Dimension Shifter (Forbidden, 0 legal copies) is run once, so it is capped to a theoretical 25 and its structural read is only indicative. The searcher-dense core (16 searcher-text copies, about 93.5 percent to have at least one in a 5-card hand) makes the engine reliably live, but the 40 slots split across Vanquish Soul, K9 and Mulcharmy with only 25.5 percent exact-name purity, which costs consistency. No recorded boards exist, so floor, median and ceiling are text-only inferences and are kept near neutral rather than credited from any single line. Interaction is reasonable (7 removal-text, 3 negation-text, multiple hand traps), and the Extra Deck carries strong closing bodies, but there is no side deck and no tournament or meta data. The score comes from consistency, interaction and closing power on the system, not from K9 or Vanquish Soul being popular archetypes, and not from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural(57) + 0.20*TournamentReliability(52) + ContextModifiers(-12) = 44; the deck is Illegal (Dimension Shifter over copy limit), so it is capped to 25 and labelled theoretical/structural-only

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

• Searcher-dense core makes the archetype engine almost always live in the opening hand (Inferred)
• Layered interaction: 7 removal-text, 3 negation-text and several hand-trap effects (Inferred)
• Strong Extra Deck closing bodies (Caesar Valius, Heavy Borger, TY-PHON, AA-ZEUS) (Verified stats)

Weaknesses

• Illegal list: Dimension Shifter is Forbidden and run at 1 copy, so the deck cannot be played as built (Verified)
• Low exact-name purity (25.5 percent) across three sub-archetypes weakens engine coherence (Verified composition)
• No side deck: no post-side adaptability (Verified composition)
• No recorded boards or tournament data to confirm any line (Verified absence)

Critical choke points

• Dimension Shifter must be removed before the list is legal; no other single card is a choke point in the evidence (Verified)
• Hand-summon routes depend on revealing monsters from hand, so a hand-disruption interaction could stall the first turn (Inferred)

Recommended changes

Evidence & confidence

• Verified: Dimension Shifter is Forbidden with 0 legal copies and is run at 1 copy, making the list Illegal; Main 40 and Extra 15 are within Master Duel size rules; Side 0 is legal; Exact-name purity 25.5 percent and sub-archetype spread from the composition block; Per-card hypergeometric probabilities from the evidence; Archetype usage stats show the K9 and Vanquish Soul core is standard (confirms real, not strong)
• Inferred: Engine consistency (D1) and brick rate (D2) from hypergeometric and composition reads; Interaction quality from text-role hints and card text; Going-first and going-second plans from card text, with no recorded boards; Closing power from Extra Deck stats and text
• Provisional: Meta Power (no dated metagame sample supplied); Matchup fit and format fit (D13)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record are absent No win-rate telemetry for going-first, going-second, matchup, brick or OTK rates Meta Power is provisional unless a dated metagame sample is supplied No side deck, so post-side performance cannot be assessed
