Railway Deck #6984 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz and Link beatdown: Train Xyz monsters (Superdreadnought Rail Cannon Gustav Max and Super Dora) plus Jizukiru and Super Express Bullet Train pressure the board. The 2000-damage detach effect of Gustav Max is the reach.; Kaiju Special Summon lines (Gameciel, Jizukiru) and Revolving Switchyard-driven damage prevention with Level 4 EARTH Machine follow-up.
• Turn 1 (going first): Open with Urgent Schedule, Pot of Desires or Heavy Freight Train Derricrane to find an EARTH Machine Train and set up a Xyz or Link board. The deck is built to make a single turn-1 play rather than a full combo.
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Infinite Impermanence and Effect Veiler to stop the opponent's first summon, then use Kaiju or Train monsters to answer the board.
• Recovery: Recover with Pot of Desires and the Train searchers (Super Express Bullet Train, Heavy Armored Train Ironwolf), then rebuild through Xyz Summons from the Extra Deck.
• After siding: Not evaluable. The Side Deck is empty (0 cards), so there is no post-side plan.

Why it scores here

The deck is scored as a Midrange system, not as an average of its cards. Its starter access is moderate: the probability of at least one Train starter (Urgent Schedule, Pot of Desires, Derricrane) in a 5-card opening hand is about 0.34 per 3-copy card, and the archetype core group has about 0.85 odds of at least one piece in hand (Inferred). Interaction is broad, with 16 negation-text and 17 removal-text cards and 9 hand traps, which earns a fair end-board interaction score. Two of its restricted cards are Forbidden in Master Duel (Called by the Grave x2, Apollousa x1) and Maxx C is over its limit, so the list is Illegal and the final score is capped low; the result is theoretical and structural only. No combos, tournament results, win rates or Side Deck exist, so the Floor, Median and Ceiling scores are inference from text. Popularity and archetype familiarity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 43.3, Going First ≈ 40, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); illegal-list cap (-13.6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*43.3 + 0.20*35 - 8 = 33.6, then capped to 20 because the deck is Illegal (3 copy-limit or banlist violations)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Interaction breadth: 9 hand traps and 16 negation-text cards give several answers to the opponent's first summon
• Redundant Train starters at 3 copies each (Urgent Schedule, Pot of Desires, Derricrane, Super Express Bullet Train, Stampede) raise the chance of a turn-1 play
• Strong Extra Deck closers: Gustav Max direct damage and Liebe ATK boost, with Gangaridai and Super Dora as Xyz options

Weaknesses

• Illegal list: Called by the Grave and Apollousa are Forbidden and Maxx C is over its limit
• Empty Side Deck means no post-side adaptation
• Heavy reliance on situational Monster Reborn and Harpie's Feather Duster, with few sources of engine redundancy
• No measured combo or win-rate evidence in YGOVN

Critical choke points

• The turn-1 Train starter: only about one-third of hands with 3 copies of a starter contain one
• Forbidden and over-limit cards in the Main and Extra Deck would have to be removed before the list could be played in Master Duel

Recommended changes

Evidence & confidence

• Verified: Main Deck 40 and Extra Deck 15 cards are within the Master Duel size rule; Called by the Grave (x2) and Apollousa (x1) are Forbidden, and Maxx C (x2) is over its Limited cap of 1; Card text for 20 distinct Main Deck cards and 12 distinct Extra Deck cards is present
• Observed: The usage statistics show that the deck runs 5 of 25 archetype core cards
• Inferred: Starter access and brick estimates come from the hypergeometric probabilities; Interaction quality comes from card text and hand-trap counts; Going-second strength comes from card text and one guide snippet
• Provisional: Meta Power is null, and the matchup and format-fit score (D13) is provisional
• 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 are absent No win-rate telemetry exists for going-first, going-second, matchup or starter rates Meta Power is provisional without a dated metagame sample The Side Deck is empty, so post-side scoring is not possible Data inconsistency: usage statistics lists Superdreadnought Rail Cannon Gustav Max, Number 81 Super Dora and Juggernaut Liebe as missing core cards, yet the cards list shows them in the Extra Deck (x2 each). Core-card presence (20%) may be understated Guide snippets are short Vietnamese excerpts with no section structure and cannot confirm a full line
