Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Tempo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Rank 5 Xyz and Link board pressure from K9 and Vanquish Soul summons, closed by 2400-3000 ATK boss monsters; Hand-trap-supported grind through repeated searches and recursion
• Turn 1 (going first): Open on a searcher or Lv5 summoner (Dr. Mad Love, K9-17 Izuna, Mulcharmy) and chain hand summons into a Rank 5 Xyz such as Ripper or Jacks
• Turn 2 (going second): Use Ash Blossom, Maxx C or Droll & Lock Bird on the opponent's first engine, then follow up with the Xyz line
• Recovery: Revealed-hand Vanquish Soul summons, Stake your Soul! and Heavy Borger returning to hand
• After siding: No side deck is registered and Master Duel play gives no post-side data; no post-side plan can be assessed (Provisional)

Why it scores here

The deck reliably opens on a searcher or Lv5 summoner, with the searcher-text group at about 0.94 for at least one card in a five-card hand and several hand-summon routes (Vanquish Soul, K9 no-tribute) feeding the Xyz engine. Its interaction layer is the strongest part: three Ash Blossom, Maxx C and Droll & Lock Bird give five hand traps, backed by Masquerade, Umbral Horror and Arc Rebellion negates and Jacks and Forced Release destruction, so it can answer a first engine on either turn order. Conversion is held back because there are no recorded boards, so the ceiling and median are text-only inference, and three extra-deck monsters (K9-X Werewolf, Divine Arsenal ZEUS, Super Starslayer TY-PHON) appear to need Level 9 or Level 12 materials that the list does not contain. The K9 usage data shows the core is standard, which confirms the list is real and accessible but earns no power points, and the score comes from the system's consistency, interaction and resilience rather than from averaging card scores. Side deck and meta fit carry no data, so they are scored neutrally or low and excluded from the structural total.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63.6, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Unrecoverable dead extra slots (-2); Engine conflicts (-1); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers; Meta provisional; D13 dropped from Structural and weights re-normalized over 95 (sum of weighted scores / 95 = 63.6); 0.80*63.6 + 0.20*60 = 62.9, then modifiers -4 = 58.9, rounded to 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Five hand traps (Ash Blossom x3, Maxx C, Droll & Lock Bird) give strong going-first and going-second interaction
• Searcher density (16 cards) gives about 0.94 probability of at least one search source in a five-card hand
• Two independent summon families (K9 no-tribute summons and Vanquish Soul hand summons) provide route redundancy
• Legal at all copy limits; all restricted cards run within legal copies

Weaknesses

• No recorded boards, so combo ceiling and median are text-only inference
• Three extra-deck Xyz (K9-X Werewolf, Divine Arsenal ZEUS, Super Starslayer TY-PHON) appear to lack level-matching materials
• Off-archetype threads (Mulcharmy, Bystial, Kaiju) dilute the engine
• No side deck, so no post-side adaptation
• Several conditional summons (Izuna, Hollie Sue, Druiswurm, Magnamhut) add pilot load and dead-draw risk

Critical choke points

• Rank 5 Xyz access depends on hand summons and Lv5 monsters; if the starter is stopped, the Xyz line has few direct alternatives
• Hand-trap usage against the first engine is a one-shot resource: Ash/Maxx/Droll spent early leave no response to the second threat

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 within Master Duel size rules; All six restricted cards within legal copy limits; Copy histogram and type/attribute/level spreads match the card list; Hand-trap group P(>=1 in going-second hand of 6) = 0.5771
• Observed: K9 usage statistics show the archetype core inclusion (verified as a usage stat, not as power)
• Inferred: Engine consistency (D1) from hypergeometric starter odds and text-based summon routes; Brick estimate and dead-draw risk (D2); Combo ceiling from text only (D3); median unavailable (D4); Interaction density from card text (D7); Level 9/12 material gap for three extra-deck Xyz
• Provisional: Meta Power (null); Matchup coverage and format fit (D13, excluded from Structural); Side deck adaptability (D12) and post-side plan
• 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 absent usage_statistics in_this_deck flags contradict the cards array for 9 extra-deck cards (e.g., K9-17 Ripper, K9-66X Jacks, Rock of the Vanquisher, Number 104: Masquerade); the cards array was trusted for copy counts No win-rate telemetry: going-first/second, matchup, brick and starter rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so post-side performance cannot be assessed
