D/D/D Deck #750614 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±7 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Control
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Pendulum-based D/D engine into Extra Deck bosses (D/D/D Duo-Dawn King Kali Yuga, D/D/D Deviser King Deus Machinex, D/D/D/D Dimensional King Arc Crisis) that close through negation and high ATK; Recursion of D/D monsters from the Graveyard via Necro Slime, Dimensional King and Dark Contract effects, extending the board over several turns
• Turn 1 (going first): Open with a Pendulum set (Kepler, Gryphon, Surveyor) and a Dark Contract with the Gate search, then build a Pendulum extension toward a Level 8 or higher boss; Ash Blossom and Maxx C stay up as interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Maxx C, Dominus Impulse, Dominus Spark) to break the opponent's starter, then recover a Pendulum engine from the Graveyard
• Recovery: Rebuild from Graveyard D/D monsters (Necro Slime, Dimensional King Arc Crisis effects) and the Pendulum Zone, keeping hand-trap redundancy for the next opponent turn
• After siding: No side deck is registered; the list has 15 side slots available and currently runs none, so no post-side plan can be evaluated from the evidence

Why it scores here

The deck scores as a connected Pendulum system rather than from its card powers: three copies each of the Pendulum starters and the Dark Contract searcher give a reasonable chance of a live engine on turns 1 and 2, with a 0.34 chance of at least one Dark Contract in a 5-card opening hand (Inferred). Interaction is dense for a combo deck, with nine hand traps and 14 negation-text cards, and that layering is what carries the going-second and interruption scores. The recorded combo evidence is one board with a power index of 23, so the floor and median are scored low and the Extra Deck boss ceiling is credited only as an inference from card text. Archetype usage shows this is the standard D/D/D core, but popularity earns no points by itself, and there is no tournament or win-rate data, so the Meta and matchup dimensions stay provisional at neutral. No side deck is registered, which costs side adaptability and tournament reliability.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60, Going First ≈ 62, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*60 + 0.20*48 - 1 = 56.6, rounded to 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex 23, median 23, board-per-starter 0
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Pendulum engine: 16 Pendulum monsters in the Main Deck with 3-copy starters
• Nine hand traps and 14 negation-text cards give layered interaction for going second
• Extra Deck covers Link, Xyz, Synchro and Fusion with several 3000+ ATK closers
• Legal for Master Duel: 40 Main, 15 Extra, all copy limits respected

Weaknesses

• Recorded combo evidence is a single board (power index 23), so the median is unsupported
• No side deck registered despite 15 slots available
• Ten single-copy Main Deck cards reduce redundancy of the engine
• Dark Contract with the Zero King and Dark Contract with the Gate both cost self-damage on Standby

Critical choke points

• Dark Contract with the Gate (3 copies) is the main D/D searcher; losing it to hand traps limits the line
• Pendulum scale pairs (Kepler at 10 with Gryphon or Copernicus at 1) must both be present to Pendulum Summon

Recommended changes

Evidence & confidence

• Verified: Legal for Master Duel: 40 Main, 15 Extra, 0 Side, no violations; Restricted cards at legal copy count: Maxx C (1), Crossout Designator (1), Droll & Lock Bird (2); Card text and stats for all 36 distinct cards; Archetype usage shows the D/D/D core is standard
• Observed: Single recorded board with power index 23 and starter diversity of 1
• Inferred: P(>=1 Dark Contract with the Gate in opening 5) = 0.34 from hypergeometric estimate; Consistency, brick and interaction reads derived from card text and role tags; Extra Deck boss ceiling inferred from stats and text
• Provisional: Meta power (null); Matchup and format fit at neutral 50; Tournament reliability is provisional without a tournament link
• Data gaps: Usage statistics join only matches the Main Deck: Kali Yuga, Caesar, Tell, Solomon, Siegfried, Clovis, Arc Crisis, Alfred, Genghis, Zeus, Gilgamesh and Deus Machinex are in the Extra Deck list but are reported as in_this_deck false, so core_present_pct (52) understates the list Only one recorded combo, so median and floor are not measured No side deck, so post-side performance is absent No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates)
