Railway Deck #773390 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Train Level 10 Xyz bosses (Superdreadnought Rail Cannon Gustav Rocket 5000 ATK, Juggernaut Liebe 4000 ATK, Flying Launcher 3800 ATK) built through Night Train and Babeldecker Level 10 starters (Inferred); Gustav Max direct damage, Varudras and Jizukiru 3300 ATK bodies (Inferred)
• Turn 1 (going first): Open a Level 10 Train starter (Babeldecker normal summon or Night Train search), hold Forbidden Droplet or Urgent Schedule for the opponent's first summon, and accept some dead Mulcharmy draws (Inferred)
• Turn 2 (going second): Use Forbidden Droplet, Forbidden Crown, Urgent Schedule and Lightning Storm to clear or negate the opponent's board, then land a Level 10 Xyz boss; guide text describes the deck as stronger going second (Inferred, guide-supported)
• Recovery: Night Train Blue Traveler recursion from the GY, Revolving Switchyard, Exceptional Schedule searches and Mulcharmy draws to refill the hand (Inferred)
• After siding: Not applicable: Side Deck size is 0 and no post-side data exists for this format (Provisional)

Why it scores here

The deck reliably opens a Train starter path through two Night Train Blue Traveler, one Heavy Armored Knight Babeldecker and the searcher text (about 78% chance of at least one searcher-text card in a 5-card opening hand, Inferred). Its real strength is the system on the back end: a 15-card Extra Deck with 14 distinct Level 10 Train Xyz and Link bosses, plus a broad negation and destruction suite (Forbidden Droplet, Forbidden Crown, Urgent Schedule, Lightning Storm, Heavy Storm, Feather Duster, Maxx C). Conversion and closing reach are high on the card text, but no recorded boards exist, so the ceiling is Inferred and the median is unmeasured. The deck loses points for six Mulcharmy copies and three Pot of Sloth copies that are conditional or board-dependent, and for about 25 non-Train archetype copies that dilute the engine. Popularity and the guide text did not earn points on their own, and the score was not derived by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: 80/20. Structural ≈ 63.3, Going First ≈ 58, Going Second ≈ 72, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Mulcharmy and Pot dead-draw burden (-2); Off-archetype dilution (-1); Redundant boss options (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• Heavy Level 10 Train Xyz boss density with 14 distinct Extra cards, all slots used
• Broad negation and destruction suite (Forbidden Droplet x3, Forbidden Crown x2, Urgent Schedule x2, Lightning Storm, Heavy Storm, Feather Duster, Maxx C)
• Strong closing power with Gustav Rocket 5000 ATK and Juggernaut Liebe 4000 ATK
• Redundant boss options via two Gustav Max copies and several Level 10 Train bodies

Weaknesses

• Six Mulcharmy and three Pot of Sloth copies are conditional or board-dependent
• Only two Night Train and one Babeldecker as reliable Level 10 Train starters
• About 25 non-Train archetype copies dilute the engine
• No recorded combos, so floor and median are unmeasured

Critical choke points

• Level 10 EARTH Machine Train starters (Night Train x2, Babeldecker x1) are the main early engine
• Gustav Max (x2) as the Xyz bridge into the Rocket and Liebe bosses

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 within master-duel size rules; no violations; Harpie's Feather Duster, Heavy Storm and Maxx C are Limited at 1 copy each, which is legal; Card text and stats for all listed cards; Hypergeometric probabilities for the main deck
• Inferred: Engine consistency and brick estimates; Going-first and going-second plans; Boss conversion and ceiling from text; Interaction quality from card text
• Provisional: Meta power is null; no dated metagame sample; Side deck adaptability and matchup fit are neutral placeholders because no side deck or tournament data exists
• 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 No win-rate telemetry for going-first, going-second, matchup, brick or OTK rates Usage statistics flag in this deck as false for Gustav Max, Gangaridai, Super Dora, Flying Launcher, Gustav Rocket, Juggernaut Liebe, Divine Arsenal, Qliphort Genius, Pentestag, Double Headed Anger Knuckle, Ancient Gear Ballista, S:P Little Knight and Clockwork Knight, although they are in the Extra Deck; core-card presence of 40 is an artifact of counting main-deck cards only Archetype label is Railway but card archetypes are Train, so exact-name purity reads 0 Master Duel side deck is not used in the evidence, so post-side plans are not evaluable
