Train Deck #771533 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Combo, Xyz, Level-10 Machine engine
• Format: ocg

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Level 10 Machine Xyz beats (Superdreadnought Rail Cannon Gustav Rocket 5000 ATK, Superdimensional Robot Galaxy Destroyer 5000 ATK, Number 81 Super Dora) built off the Train Level-10 engine; Direct damage and removal from Superdreadnought Rail Cannon Gustav Max (2000 direct damage per detach) and Skypalace Gangaridai
• Turn 1 (going first): Urgent Schedule or Machina Redeployment to reach Night Train Blue Traveler / Heavy Armored Knight Babeldecker, then Level 10 Machine Xyz summons off the resulting board
• Turn 2 (going second): Answer the opponent's board with Lightning Vortex, Galaxy Destroyer's S/T destruction or Ghost Sister & Spooky Dogwood, then rebuild through Night Train Blue Traveler revival
• Recovery: Night Train Blue Traveler GY revival with another EARTH Machine monster, Machina Redeployment searches, and Revolving Switchyard for Level-10 Machine summons
• After siding: None: the deck runs 0 side cards, so there is no post-side plan (Best-of-3 adaptability is effectively absent)

Why it scores here

This list is Illegal as submitted: Superdreadnought Rail Cannon Gustav Max is run 2 copies against an OCG limit of 1, so the score is capped at 30 and the evaluation is theoretical/structural only. Structurally the deck is a coherent Train/Level-10 Machine Xyz system: a probability-backed starter core (P(at least one Urgent Schedule, Machina Redeployment, Night Train or Babeldecker in a 5-card hand) is roughly 0.90 across the archetype core, Inferred) feeds a dense set of Level 10 Machines that open a high-ceiling Xyz finish (Gustav Rocket, Galaxy Destroyer, Super Dora). Floor and median output cannot be measured because the deck supplied no parseable boards, so those dimensions stay near neutral; interaction is text-read only (7 negation and 11 removal cues, one hand trap). The score was built from consistency, engine cohesion, closing power and the lack of a side deck, not from averaging card scores, and archetype popularity or usage stats were not credited as strength.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-3); side_deck_absent (-3); off_archetype_engine_dilution (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*54.65 + 0.20*45 - 8 = 44.7; Illegal list capped at 30 (theoretical/structural-only); Meta Power provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Probability-backed starter density: archetype core ≈ 0.905 to appear in a 5-card opening hand (Inferred)
• Four independent Level-10 Machine starters create multiple routes into the Xyz finishers
• High closing power from Gustav Rocket and Galaxy Destroyer at 5000 ATK
• Compact Extra Deck with redundant Rank-10 Xyz options

Weaknesses

• Illegal as submitted: Gustav Max copy limit exceeded (2 run, limit 1)
• No side deck, so no post-side adaptation
• Only one hand trap and no floodgate for going-second interaction
• Large off-archetype share (30 of 42 main copies) dilutes engine cohesion
• Complex multi-step summoning sequence lowers pilotability

Critical choke points

• Level-10 Machine presence: many lines require an EARTH Machine Level-10 monster on board, so one clean removal of the starter can end the turn
• Gustav Max must be cut to one copy to be legal, which removes a direct-damage and Rocket-transfer route
• Night Train revival depends on a GY Level-10 EARTH Machine target

Recommended changes

Evidence & confidence

• Verified: Main deck size 42 and Extra deck size 15, both legal for OCG; Superdreadnought Rail Cannon Gustav Max: 2 copies run against an OCG limit of 1 (Limited); Card text for the 25 distinct main cards and 10 distinct Extra cards; Exact-name archetype purity 47.4%
• Inferred: P(at least one archetype-core card in a 5-card opening hand) ≈ 0.905; Interaction, brick and pilotability reads from card text; Combo ceiling is text-only inference: no parseable boards
• Provisional: Meta Power (null) and matchup fit (D13) — no dated metagame sample; Median output (D4) — no recorded boards
• Data gaps: Illegal list: Gustav Max is run 2 copies against an OCG limit of 1; the score is capped and theoretical only No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No side deck: post-side plan cannot be evaluated No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick/starter/OTK rates); those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage statistics ref matching looks inconsistent: Gustav Rocket (92359409), Super Dora (49032236) and Juggernaut Liebe (26096328) are reported in this deck=false even though the cards list shows them in the deck; core-card presence (40) is not trusted until the ref mapping is checked
