Railway Deck #759334 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz/Link/Fusion boss monsters from the Extra Deck (Superdreadnought Rail Cannon Gustav Rocket at 5000 ATK, Juggernaut Liebe, Super Dora) backed by Train-engine searches and Level 10 Machine recursion; Gustav Max direct damage and Mulcharmy card-draw attrition in long games
• Turn 1 (going first): Open Train searchers (Night Train Blue Traveler, Exceptional Schedule, Urgent Schedule) to reach a Level 10 Machine boss; hand-trap backup is limited to Droll & Lock Bird and Maxx "C"
• Turn 2 (going second): Use Droll & Lock Bird, Maxx "C" and Heavy Storm / Harpie's Feather Duster to answer the opponent's first board, then rebuild through Revolving Switchyard and Babeldecker
• Recovery: Night Train Blue Traveler and Mulcharmy draw effects refill the hand; Scrap Recycler and Clockwork-style recursion are only partly present in this list
• After siding: No side deck is registered in the export; post-side adaptation cannot be evaluated

Why it scores here

The deck reliably opens a searcher-based Train engine: P(at least one of the 9 searcher-text cards in a 5-card opening hand) is about 0.74, and two Night Train and two Urgent Schedule copies provide the bridge to Level 10 Machines. Conversion depends on the Extra Deck: Gustav Rocket, Liebe, Super Dora and Flying Launcher give high closing ATK once a Rank 10 or Level 10 base is established. Floor and median output cannot be assessed because no recorded boards exist, so those scores are text-based inferences. Interaction is layered (Droll & Lock Bird, Maxx "C", Heavy Storm, Harpie's Feather Duster, Machina Ruinforce, Gustav Rocket negation) but is spread over several Limited and Semi-Limited cards, and the Fusion section relies on a single enabler and a Dragon requirement the main deck does not meet. The score comes from consistency, closing power and interaction on the system; Railway's archetype popularity earned no points and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (not blended numerically; Combo weights used). Structural ≈ 53.9, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-2); single Extra-Deck enabler and unmet Dragon requirement (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural uses the Combo weight profile

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Searcher density (9 cards) gives a P(≥1 in opening hand) of about 0.74
• High-ATK Extra Deck closers (Gustav Rocket 5000, Liebe 4000, Super Dora 3200)
• Layered hand-trap and backrow interaction (Droll & Lock Bird, Maxx "C", Heavy Storm, Harpie's Feather Duster)

Weaknesses

• No recorded combo boards, so floor and median output are unmeasured
• Nine singleton slots and six Mulcharmy copies add weak or dead-in-hand cards
• Fusion section depends on one enabler and a Dragon requirement the main deck does not meet
• No side deck registered, so post-side play is unassessed

Critical choke points

• Reaching a Level 10 Machine base (Night Train or Babeldecker) to unlock the Extra-Deck boss line
• Super Polymerization as the sole Fusion enabler for the four Fusion cards

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 legal in master-duel; All restricted cards run at or below their legal copy limit; Searcher-text count 9 and hand-trap count 3 from role tags; Extra Deck stats and Extra-Deck breakdown
• Observed: Usage statistics show the archetype core is partly present (10 of 25 core cards)
• Inferred: P(≥1 searcher in opening 5) ≈ 0.74 and per-starter ≈ 0.34; Brick and dead-in-hand risk for Mulcharmy and off-engine cards; Going-first and going-second estimates from interaction counts; Closing power from Extra-Deck ATK and text
• Provisional: Meta Power and matchup fit (no dated metagame sample); Tournament reliability (no win-rate telemetry)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null; archetype is recorded as Railway while most cards carry the Train archetype tag no side deck registered in the export
