Train Deck #32623 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, 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 Xyz and Link pressure from Super Dora, Gustav Max, Liebe, Super Express Bullet Train, Night Express Knight and Heavy Freight Train Derricrane; Galaxy Destroyer and Great Magnus as high-ATK finishers once the Train engine has produced board presence
• Turn 1 (going first): Open a Train starter (Ruffian Railcar, Flying Pegasus Railroad Stampede or Super Express Bullet Train) that reaches a Level 10 Machine, then Xyz or Link into the Extra Deck boss while holding Ash Blossom or Infinite Impermanence
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence and Twin Twisters to stop the opponent's setup, then rebuild the Train board through graveyard special summons from Railcar, Derricrane and Pegasus
• Recovery: Recurse Level 10 Machines and Train monsters from the graveyard with Ruffian Railcar's effect and Flying Pegasus Railroad Stampede, and use Revolving Switchyard for a battle-damage shield and an extra Level 4 Earth Machine
• After siding: No side deck is registered (0 cards), so there is no post-side plan to evaluate. Adding one would be the first change to make if the list is brought into a legal state

Why it scores here

The deck's consistency rests on a six-card Train engine run at three copies each, plus a three-copy searcher and two-copy hand traps. Starter access is good: the probability of at least one searcher-text card in a going-first opening hand is about 0.85, and each three-copy starter is about 0.34 on its own (Inferred). Pressure is the deck's strongest area, because its Extra Deck holds several 3000+ ATK Level 10 bosses and Galaxy Destroyer at 5000 ATK. Interaction is real but thin, with hand traps and spell/trap removal that depend on the opponent's line. The score comes from the deck as a system: engine access, recursion and closing power, not from averaging card strengths or from the archetype's popularity. Recorded boards are absent, so the floor, median and ceiling are text-based inference, and the legality failures cap the final result at a theoretical level.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-10); key card limited status (-2). Final formula: No reliable metagame, so Meta is provisional: 0.80*Structural(59) + 0.20*TournamentReliability(52) = 57.6; context modifiers -12 = 45.6; Illegal-list cap applied, final = 30 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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

• Six Train engine cards at three copies each give strong starter access
• Extra Deck bosses reach 3000+ ATK and Galaxy Destroyer reaches 5000 ATK
• Graveyard recursion from Railcar, Derricrane and Pegasus supports recovery

Weaknesses

• Illegal list: Terraforming is Forbidden and Maxx C is over the copy limit
• No side deck, so there is no best-of-three adaptation
• Core archetype coverage is low (2 of 25 standard core cards present)

Critical choke points

• Dependence on a Level 10 Machine to start the Xyz and Link chains
• Night Express Knight cannot be Special Summoned from the Deck, so it is a normal-summon-only card

Recommended changes

Evidence & confidence

• Verified: Legality: 40 main, 15 extra, 0 side; Terraforming Forbidden with 1 copy; Maxx C Limited with 3 copies; Card text and stats for the Train engine, Extra Deck bosses and hand traps; Archetype spread: 29 of 40 main and Extra cards exact Train
• Inferred: Starter probabilities (hypergeometric from the Main Deck); Going-first and going-second power estimates; Interaction and recursion quality from card text
• Provisional: Matchup fit and format fit (no tournament link or dated meta sample); Meta Power (null)
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match records are absent No win-rate telemetry exists for going-first, going-second, matchups or brick rates Meta Power is provisional unless a dated metagame sample is supplied No guides attached for the archetype No side deck registered
