Train Deck #41447 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±8 · Confidence: Low)

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

Legality

Main 49 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Rank 10 and Rank 11 EARTH Machine Xyz beatdown (Superdreadnought Rail Cannon Juggernaut Liebe, Number 81: Super Dora, Gustav Max direct damage) built from Train Machine starters.; Infinitrack Fortress Megaclops and Infinitrack Earth Slicer as board-breaking follow-up through Xyz and Link material routes.
• Turn 1 (going first): Normal Summon a Level 10 Train starter (Heavy Freight Train Derricrane or Night Express Knight), use Revolving Switchyard or Super Express Bullet Train to build toward a Rank 10 Xyz.
• Turn 2 (going second): Hold Ash Blossom and Infinite Impermanence as quick interaction, then use Special Schedule or Monster Reborn style recursion to rebuild a Level 10 Machine board.
• Recovery: Recover Level 10 Machines from the Graveyard with Special Schedule, Infinitrack Tunneller and Infinitrack Brutal Dozer, then rebuild Xyz material.
• After siding: Not applicable: the deck has no side deck, so there is no post-side plan.

Why it scores here

This list has a real Train engine: three copies each of the Level 10 Machine starters give roughly a 28% chance of at least one in a 5-card opening hand, and searchers are dense enough that some starter is reachable in most hands. Its interaction suite (two Ash Blossom, Infinite Impermanence, Solemn Judgment, Mystical Space Typhoon, Raigeki, Harpie's Feather Duster) gives it layered disruption, which is what lifts the structural read. The list is held down by its brick risk, its low exact-name purity (about 45% of cards carry the Train name, with Infinitrack cards filling much of the rest), and the absence of any recorded boards, so the score is built from card text and probability rather than observed play. The Extra Deck holds 18 cards against a Master Duel limit of 15, so the list is illegal as built; the score is therefore a structural, theoretical read capped low, and popularity or archetype usage earned no points. No card scores were averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 52, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal Extra Deck size (-8); Low exact-name purity and engine dilution (-4). Final formula: Illegal (Extra Deck 18 > 15): theoretical structural read only. 0.80*Structural(53) + 0.20*TournamentReliability(45) = 51.4, then modifiers -12 = 39; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.28 · 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 searcher text (15 searchers) makes a starter reachable in most hands
• Layered interaction: two Ash Blossom, Infinite Impermanence, Solemn Judgment, Mystical Space Typhoon, Raigeki
• Strong Rank 10 and Rank 11 Xyz closers with Gustav Max direct damage

Weaknesses

• Extra Deck is over the 15-card limit, so the list is illegal as built
• Low exact-name purity; Train and Infinitrack pieces do not form one engine
• No side deck, so no post-side adaptability
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Level 10 Machine starters are single-copy-dependent for the Rank 10 Xyz route
• Tributes are required for several Summons, so an early Level 10 starter without a second body stalls the turn

Recommended changes

Evidence & confidence

• Verified: Main Deck 49 cards, Extra Deck 18 cards (size violation confirmed); Restricted cards Harpie's Feather Duster, Monster Reborn and Solemn Judgment each run 1 copy, all Limited (legal); Card texts and stats for the deck's core Train and Infinitrack cards
• Inferred: Opening-hand starter and searcher probabilities (hypergeometric estimate); Brick risk from Tribute and Normal Summon sequencing; Structural dimension scores and interaction quality from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: No recorded combos for this deck, so ceiling and median output are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry; going-first and going-second splits are Inferred Archetype usage core list does not match the Train core (lists unrelated cards), so it was not used for core-card judgments Meta Power is Provisional until a dated metagame sample is supplied
