Train Deck #768235 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo
• Format: ocg

Legality

Main 51 / Extra 21 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Level 10 Train monsters (Night Train Blue Traveler, Night Express Knight, Super Express Bullet Train) and Rank 10 Superdreadnought Rail Cannon Xyz monsters (Gustav Max, Flying Launcher, Super Dora) overwhelm the board; Machina Citadel and Therion King Regulus as board breakers, with Infinitrack and K9 Xyz lines as alternate pressure
• Turn 1 (going first): Exceptional Schedule or Night Train Blue Traveler searches a Train engine card, Revolving Switchyard or Urgent Schedule supports a Level 10 summon, then Ash Blossom and Infinite Impermanence protect the first Level 10 play
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Infinite Impermanence and Construction Train Signal Red to answer the opponent's first summon, then rebuild a Level 10 board from the Graveyard with Night Train and Super Express
• Recovery: Graveyard recursion through Night Train Blue Traveler, Super Express Bullet Train and Ruffian Railcar, plus Infinitrack Tunneller drawing 2 after 5 Machines return
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan (Inferred)

Why it scores here

The deck reliably opens a Train engine: 19 searcher-text cards and a hypergeometric estimate of about 0.91 for at least one searcher in an opening 5 (Inferred), anchored by three Night Train Blue Traveler and three Exceptional Schedule. Its conversion is a Level 10 board built from Train searchers, Revolving Switchyard, and Rank 10 Superdreadnought Xyz, with 13 negation-text and 6 hand-trap cards covering the opponent's first plays. The score comes from consistency, median output, and interaction read on the whole system; no combo boards were recorded, so the conversion and floor scores are text-based inferences. The deck is Illegal as built (Ash Blossom at 3 copies against a limit of 2, and 21 Extra Deck cards against a maximum of 15), so the Final score is capped to a theoretical, structural-only value. Archetype popularity (Train, 16 core copies, roughly 86% of hands with at least one core card) earned no points by itself, and card scores were not averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-6); engine_compactness (-2). Final formula: No reliable metagame, so Meta is provisional: blend 0.80*Structural(56) + 0.20*TournamentReliability(45) = 54, then the Illegal cap applies (the deck gets no normal Final score) and the score is set to 38, labeled theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Engine density: 19 searcher-text cards and 3 Night Train plus 3 Exceptional Schedule give a high chance of a live starter
• Interaction breadth: 6 hand traps, 13 negation-text cards and Droll & Lock Bird answer both turns
• Recursion: Graveyard Train revival (Night Train, Super Express Bullet Train) can rebuild a board after a clean answer

Weaknesses

• Illegal as built: Ash Blossom copy limit is exceeded and the Extra Deck is 6 cards over the maximum
• Extra Deck bloat: 21 cards with 11 Link and 10 Xyz, many of them unused by the core engine
• No Side Deck, so there is no post-side adaptation
• Loose Main Deck: 17 singleton cards and 14 level-0 spells or traps dilute the Train engine

Critical choke points

• Revolving Switchyard and Night Train are the only searchers that reach the Level 10 engine in a single step
• Ash Blossom x3 removal is the only way to clear an early hand-trap line in the current build, and it is illegal as built

Evidence & confidence

• Verified: Main 51 within 40-60 and Extra 21 above the 15 maximum (legality); Ash Blossom & Joyous Spring: 3 copies run vs 2 legal (Semi-Limited); Limited status: Droll & Lock Bird, S:P Little Knight, Sky Striker Mecha Hornet Drones, Gustav Max; Card text for the 51 Main and 21 Extra cards (resolved except one passcode); Archetype core share 47% present in deck (usage stats)
• Inferred: P(>=1 searcher in hand 5) ~0.91, 14% core brick proxy; Consistency, interaction and recursion reads from card text; Structural 56 using the Midrange profile; Going-first 52 and going-second 58 estimates
• Provisional: Meta Power (null: no dated sample); Tournament Reliability 45 and matchup fit D13 50 (no tournament or meta 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 1 passcode in CardIDList (10443957) could not be resolved to a card and was counted as Main No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional: no dated metagame sample supplied No Side Deck in the export (0 cards)
