Train Deck #771545 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 41 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Train Extra Deck boss (Superdreadnought Rail Cannon Gustav Rocket / Flying Launcher) and K9-X Ripper/M piercing pressure, reached through Train and K9 searchers; Crystron Eleskeletus and K9-66X Jacks board control and removal
• Turn 1 (going first): Search and summon Train or K9 starters (Night Train Blue Traveler, K9-66b Lantern, Revolving Switchyard), then Xyz into a 9-10 Level boss; not verifiable as a line because no combos were recorded
• Turn 2 (going second): No side deck is present, so the plan depends on hand-trap-free disruption (Forbidden Droplet, Forbidden Crown) that is not reliable through a 6-card hand
• Recovery: Searchers (15 text-tagged) and Crystron recursion; the deck has no recorded recovery line
• After siding: Not applicable: the deck has no side deck (Side Deck size 0)

Why it scores here

This deck is scored as a connected system, not as an average of its cards. It is built from three overlapping engines (Train, K9 and Crystron) with only 11 of 41 main-deck copies in the exact Train archetype, so the engines compete for hand space. Its starters are reachable most of the time through searchers (about 91% for at least one searcher in a 5-card opening hand, Inferred), but any single 3-copy starter is live in only about 33% of opening hands. Interaction is reasonable (17 removal-text and 7 negation-text cards) and the Extra Deck offers strong boss options, but no recorded boards exist, so combo ceiling and median output are text-only inferences. The deck is illegal in OCG as submitted (3 copies of K9-17 Izuna against a limit of 2), so it receives a capped low score and this is structural-only. Popularity or the archetype name did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 44, Going First ≈ 42, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: illegal copy limit (-8); unresolved passcode (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal deck capped low, structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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

• Searcher density (15 text-tagged cards) makes the engine reachable most of the time
• Layered removal and negation (17 removal, 7 negation text cards)
• Extra Deck bosses with high ATK and piercing or direct damage

Weaknesses

• Three archetype families (Train, K9, Crystron) compete for hand space; only 20% exact-name purity
• Illegal copy count (K9-17 Izuna) and one unresolved passcode
• No side deck and no recorded boards to validate any line

Critical choke points

• Single 3-copy starters are live in about 33% of opening hands
• Rank 10 Train Xyz access depends on a small number of materials

Recommended changes

Evidence & confidence

• Verified: Copy-limit violation for K9-17 Izuna (3 vs 2); Banlist status of A Case for K9, K9-66a Jokul, and Superdreadnought Rail Cannon Gustav Max (Limited, 1 copy each); Card text for Gustav Rocket and K9-X Ripper/M; Side deck absent (Side Deck size 0)
• Observed: Usage: Revolving Switchyard (80.8%) and Mulcharmy Fuwalos (69.2%) appear as common core cards in the archetype
• Inferred: Starter access from the hypergeometric estimate; Consistency and brick rates; Interaction density and resilience from text
• Provisional: Meta Power (no dated metagame sample); Matchup fit
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent 1 passcode in CardIDList could not be resolved (counted as main) no win-rate telemetry; going-first, going-second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
