Railway Deck #51395 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Level 10 EARTH Machine Train monsters (Derricrane, Night Express Knight, Super Express Bullet Train) enable Rank 10-11 Xyz bosses (Gustav Max, Super Dora, Liebe) that attack or burn for the win; Kaiju summons (Jizukiru, Gameciel, Gadarla) and Xyz boss pressure
• Turn 1 (going first): Open on a Level 10 Machine starter or searcher, defend with Derricrane / Pegasus bodies and Ash Blossom, then Xyz into a rank 10 boss on turn 2
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Infinite Impermanence, Maxx C) and Kaiju Special Summon to answer the opponent's board, then rebuild a Train Xyz boss
• Recovery: Recycle Train monsters from the Graveyard through Derricrane and Switchyard, and re-Xyz from the remaining Level 10 Machine bodies
• After siding: Not applicable: Master Duel has no Side Deck in this format (Side Deck size 0)

Why it scores here

The deck is scored as a system, not as an average of its cards. Its reliable opening is a Train starter: P(at least one of the nine engine or searcher cards in a 5-card opening hand) is about 0.74 (Inferred), and the Level 10 Machine chain then reaches rank 10 and 11 Xyz bosses (Gustav Max, Super Dora, Liebe) that give it closing power. Interaction is dense for Master Duel, with 18 negation-text and 14 removal-text cards, 10 hand-trap copies, and about 0.85 odds of holding a hand trap as the second player. Median output and the combo ceiling are not measured because the deck has no recorded boards, so both scores are text-based inference. The legality failures (three Maxx C against a limit of one, and two Forbidden Called by the Grave) cap the final score, which is therefore theoretical and structural only. Popularity and the Railway archetype's presence in guides earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange 100% (Stun blend not applied; the Midrange profile fits the Train Xyz body plan). Structural ≈ 55.5, Going First ≈ 58, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*55.5 + 0.20*45 - 12 = 41.4; Illegal cap applied, so the score is set to 35 and labelled theoretical/structural-only

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

• Dense hand-trap and negation package (10 hand traps, 18 negation-text cards)
• Strong Level 10 Machine Xyz boss pool with direct-damage and ATK closing
• Searcher and recycler density reduces starter dependency

Weaknesses

• Illegal in Master Duel: three Maxx C against a limit of one, and two Forbidden Called by the Grave
• Heavy reliance on 3-copy staples and generic cards, which lowers Train engine coherence
• No side deck, so no post-side adaptation

Critical choke points

• Level 10 Machine starter in hand (Derricrane, Night Express Knight, Super Express Bullet Train)
• Rank 10 Xyz boss availability after the first Xyz Summon

Recommended changes

Evidence & confidence

• Verified: Main Deck 40 cards and Extra Deck 15 cards, both within Master Duel size rules; Called by the Grave is Forbidden and Maxx C is Limited (1 copy); Card text for the Train, Kaiju and Xyz boss cards; Hypergeometric draw odds from the resolved Main Deck list
• Inferred: Starter access and brick risk from the hypergeometric draw odds; Interaction density from negation and removal text; Going-second hand-trap availability; Engine coherence and off-archetype weight
• Provisional: Meta Power and format fit (no dated metagame sample); Tournament reliability (no win-rate or match data)
• 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 exists for this deck usage statistics in this deck flags are false for Extra Deck cards that appear in the cards list, so core-presence figures are unreliable for the Extra Deck Meta Power is Provisional unless a dated metagame sample is supplied
