D/D/D Deck #751108 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Deck boss summons (D/D/D Zero Doom Queen Machinex, Deus Machinex, Kali Yuga, Wave High King Caesar, Arc Crisis) enabled by Pendulum setups and Dark Contract searches; Negation-heavy interaction (Ash Blossom, Ghost Belle, Droll, Dominus Impulse, Maxx C, Infinite Impermanence) that protects the board while the deck rebuilds
• Turn 1 (going first): Set the Pendulum Zones with D/D Savant Kepler, D/D Scale Surveyor, D/D Gryphon or D/D Savant Copernicus, use Dark Contract with the Gate to search a D/D monster, then Pendulum or Extra Deck summon toward a boss monster while holding hand traps for the opponent's first response
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Droll and Lock Bird, Maxx C, Dominus Impulse) to negate the opponent's first Special Summon or search, then rebuild a Pendulum setup and Extra Deck boss from the remaining hand
• Recovery: Use Dark Contract cards and D/D monsters in the Graveyard as recursion: D/D Necro Slime can Fusion Summon from the GY, D/D Lance Soldier can be Special Summoned from the GY by destroying a Dark Contract, and Dark Contract with the Gate restocks the hand
• After siding: Not applicable: Master Duel has no side deck (side size 0 is within the format rule of 0-15)

Why it scores here

The deck is scored as a connected system: its Pendulum starters and Dark Contract searches make a D/D/D Extra Deck boss reachable in a usable share of openings (P of at least one 3-copy starter in a 5-card hand is about 0.34, and a searcher is in hand about 0.82 of the time, both Inferred from the hypergeometric draw table). Nine hand traps and about 14 negation-text cards give it real interaction, most of which is strongest going second (P of at least one hand trap in a 6-card hand is about 0.81). The Extra Deck is well stocked with high-ATK bosses (up to 4000 ATK Arc Crisis and 3500 ATK Kali Yuga), which earns closing and Extra Deck points. Recorded combo evidence is thin: the best recorded line is 39 power index against a median of 28, with no board or interaction data, so the ceiling and median are both held down and labeled Inferred. Popularity of the archetype and usage statistics only confirm that the list is real and standard, and they added no points on their own; card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57.6, Going First ≈ 56, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-1); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-3) = 0.80*57.6 + 0.20*52 - 3 = 53.5, rounded to 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex 39, median 28, board-per-starter 0
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense negation and hand-trap suite that is strongest going second
• Extra Deck boss bodies reach 2800 to 4000 ATK with 15 varied Extra slots
• Legal list with all restricted cards at their legal limits

Weaknesses

• Pendulum and Dark Contract dependence creates opening-hand variance
• Recorded combo evidence is thin and has no board data, so the ceiling is hard to confirm
• Several Main Deck cards are situational tech or off-plan at the common opening

Critical choke points

• The first Pendulum setup or the Dark Contract search: a missed setup leaves the hand without a Pendulum plan
• The opponent's first Special Summon or search, which the hand traps must answer

Recommended changes

Evidence & confidence

• Verified: Legal under BanMasterDuel; Limited Maxx C and Crossout Designator at 1 copy, Semi-Limited Droll at 2 copies; Main 40 and Extra 15 are within the Master Duel size rules; Card stats and text excerpts for the listed cards
• Observed: Recorded combo power distribution: min 9, median 28, max 39 over 7 lines
• Inferred: Starter access probabilities from hypergeometric draws; Going-second interaction strength from hand-trap odds; Engine conflict and pilotability reads from card text and sequencing
• Provisional: Meta and format fit (D13); no dated metagame sample; Side-deck adaptability (D12); no side deck in Master Duel
• Data gaps: No tournament link: archetype meta-share and per-pilot match records are absent No win-rate telemetry for going-first, going-second, matchup, brick or starter rates; those signals are Inferred Recorded combos have gameplay 'unknown' and no board data (average interaction density 0, board per starter 0), so ceiling and interaction are weakly evidenced usage statistics in this deck flags conflict with the Extra Deck list: Kali Yuga, Wave High King Caesar, Tell, Solomon, Siegfried, Clovis, Arc Crisis, Alfred, Genghis, Zeus, Gilgamesh and Deus show in this deck=false or copies_in_deck=0 although they are present in extra; the core-presence figure of 52% is unreliable and was not used to score Deck title is null; the deck is identified by archetype only Master Duel has no side deck, so D12 has no real evidence
