D/D/D Deck #750644 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±7 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Blind-Second/OTK
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Extra Deck D/D/D boss summons (Deus Machinex, Bright Armageddon, Arc Crisis) enabled by Pendulum-zone setup and Dark Contract recursion; Negation and hand-trap led control that converts into a going-second board break and OTK
• Turn 1 (going first): Open a starter, search a second Pendulum monster with Dark Contract with the Gate, Pendulum Summon, then Extra Deck boss summon
• Turn 2 (going second): Use hand traps (Ash Blossom, Effect Veiler, Dominus Impulse) to stop the opponent's first summon, then rebuild the D/D engine through the board
• Recovery: Dark Contract recursion, Necro Slime and Lance Soldier from the GY, and Orthros from the hand to re-establish Pendulum and Extra summons
• After siding: Not applicable: Master Duel export has no side deck, so no post-side plan is scored

Why it scores here

The deck opens reliably: 12 searcher-text cards put at least one into a 5-card opening hand about 85% of the time, and the archetype-core group gives roughly 96% of hands at least one D/D card (Inferred, hypergeometric). Its ceiling is high because the Extra Deck carries boss-level summons (Deus Machinex 3000, Wave High King Caesar 2800, Bright Armageddon 3500, Arc Crisis 4000 ATK) and the negation density (Ash, Veiler, Dominus Impulse, Siegfried) lets it break an established board, especially going second. The score is held back by the absence of any recorded boards, so the median and floor are text-only inference, by conditional tech (Triple Tactics, Small World, Spirit's Mastery) that is often dead, by Mulcharmy draws that want an empty field, and by 1000-damage life costs. Popularity in the guides and the presence of usage statistics confirm a real, accessible list but earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 67.8, Going First ≈ 70, Going Second ≈ 73, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: engine conflict (Mulcharmy) (-2); life-point burn (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*67.8 + 0.20*57 = 65.7, then modifiers -3 = 62.7, rounded to 63

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Two-card bootstrap: 12 searcher-text cards put one in the opening 5 about 85% of the time (Inferred)
• Extra boss ceiling: Arc Crisis 4000, Armageddon 3500, Deus Machinex 3000 ATK (Verified card text)
• Negation density: Ash x3, Veiler x2, Impulse x3, Siegfried, Wave High Caesar (Inferred, semantic)

Weaknesses

• No recorded boards, so median and floor are unmeasured (Observed absence)
• Conditional tech (Triple Tactics, Small World, Spirit's Mastery, Forbidden Crown) can be dead in hand (Inferred)
• Mulcharmy draws conflict with the Pendulum-zone plan (Inferred)
• No side deck to adapt between games (Verified)

Critical choke points

• Dark Contract with the Gate (3 copies) is the main searcher into the D/D monster set (Inferred)
• Extra Deck summon routes need Pendulum or Dark Contract setup; a single disruption to the Pendulum zones can drop the line (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legal: 40 main (range 40-60), 15 extra (range 0-15), 0 side (range 0-15), no violations, no Limited or Forbidden cards; Card text and ATK/DEF values from the export; usage_statistics present (32 rows)
• Observed: No recorded boards exist in combos_evidence (0 boards)
• Inferred: Opening-hand consistency from hypergeometric draw tables; Ceiling, going-second and interaction reads from card text; Off-archetype and conditional tech conflicts from text
• Provisional: Meta Power (no dated sample); D12 side adaptability (no side list); D13 matchup and format fit (no tournament context)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No side list in the Master Duel export, so D12 is unmeasured usage_statistics in_this_deck flags are false for Extra Deck cards the deck does run (Deus Machinex x2, Wave High King Caesar x1, Gilgamesh x2, Sky King Zeus x1, Arc Crisis x1, Clovis x1, Tell x1, Solomon x1, Siegfried x1, Alfred x1, Genghis x1, Bright Armageddon x1), so core_present_pct 40 is understated; treat as an export defect No win-rate telemetry exists in YGOVN Guides are prose snippets with no sections
