D/D/D Deck #766334 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Deck D/D/D boss monsters (Deus Machinex x2, Arc Crisis, Kali Yuga, Gilgamesh x2, Siegfried, Caesar) summoned off a Pendulum-zone and Graveyard setup (Inferred from card text); Dark Contract standby damage and direct Extra Deck pressure from Link and Xyz bosses (Inferred from card text)
• Turn 1 (going first): Set two D/D Pendulum monsters (Kepler, Gryphon, Surveyor, Copernicus) to open the Pendulum zones, search with Dark Contract with the Gate or Surveyor, then Pendulum Summon into a boss (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C, Ghost Ogre and Dominus Impulse to answer the opponent's summons, then rebuild from the Graveyard with Necro Slime, Lance Soldier and Clovis (Inferred)
• Recovery: Graveyard recursion: Necro Slime fuses from the GY, Lance Soldier revives from the GY via a Dark Contract, Genghis and Clovis re-summon D/D monsters (card text)
• After siding: None: the deck runs a 0-card Side Deck, so there is no post-side plan (verified from legality)

Why it scores here

The deck's score comes from how the system behaves: it reliably finds a D/D starter (11 searchers give P(at least one in a 5-card opening hand) ≈ 0.82, and the 22-card archetype core gives ≈ 0.99 for at least one core card), it carries a dense interaction suite (Ash, Droll x2, Maxx C, Ghost Ogre, Dominus Impulse, Crossout, plus negate effects on Siegfried, Zeus, Caesar and Kali Yuga), and its Extra Deck has high-end closing bosses. Those are the strengths the score rewards. Popularity and archetype usage did not earn points: the usage-statistics join marks all 12 Extra Deck core cards as absent even though the card list contains them, so that result was not used as a power signal. Card scores were not averaged, and the 5 Mulcharmy copies, which need an empty field, were penalised as an engine conflict. No combo records, tournament data or win-rate telemetry exist, so the combo, meta and matchup dimensions are Inferred or Provisional and the band is wide.

Dimension scores

How the score was computed

Strategy profile: Combo (D13 dropped and re-normalised over 97, because Matchup is Provisional). Structural ≈ 68.6, Going First ≈ 70, Going Second ≈ 71, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: Engine conflict (-2); Weak post-side plan (-2); Full archetype core present (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural 68.6 = 6652/97 with D13 dropped; TR 54; modifiers -2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Full 25-card archetype core is present in the list (verified against cards list, despite the usage-statistics join bug)
• Dense interaction: 7 hand-trap-flagged cards plus Dominus Impulse, Crossout Designator and negate or destroy effects on Siegfried, Zeus, Caesar and Kali Yuga
• High-ceiling Extra Deck bosses (Arc Crisis 4000 ATK, Kali Yuga 3500 ATK, Machinex 3000 ATK)
• Searcher density: 11 searcher-text cards, P(≥1 in opening hand) ≈ 0.82

Weaknesses

• Five Mulcharmy copies need an empty field, conflicting with the D/D Pendulum-zone plan
• No side deck: no post-side plan
• Droll x2, Maxx C and Crossout are situational and can be dead draws
• High pilotability burden with Pendulum-scale state and many once-per-turn constraints

Critical choke points

• Pendulum-zone state: a single D/D Pendulum monster cannot open the Pendulum-zone plan alone
• Dark Contract Standby damage (1000 LP per card on the field) limits how many Dark Contracts can stay out
• Hand-trap dependence on Ash x3 and Droll x2 for going-second disruption

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main, 15 Extra, 0 Side, all restricted cards within legal copies (Crossout 1/1, Maxx C 1/1, Droll 2/2); Card text and stats for all 40 Main and 15 Extra cards from the card list; Archetype core: all 25 usage-statistic core cards appear in the card list; the usage-statistics join is wrong for Extra Deck cards
• Observed: Guide snippets describe D/D/D as a turn-1 disruption deck that relies on Extra Deck monsters (guide text, not measured)
• Inferred: Starter probabilities: P(≥1 3-copy starter in hand5) ≈ 0.34; searcher ≈ 0.82; core ≈ 0.99; brick proxy ≈ 0.013 (hypergeometric); Going-first and going-second plans and combo ceiling from card text; Interaction density and resilience counts from card text
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament context)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference usage_statistics join is wrong for Extra Deck cards: 12 Extra cards that are in the list are marked in_this_deck:false and listed as missing_core; core_present_pct 52 should be 100 no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional without a dated metagame sample deck title is null and the deck was created 2026-10-18, so there is no usage history beyond the archetype
