Identity & game plan
- Win condition: Train Xyz pressure: Superdreadnought Rail Cannon Gustav Rocket (5000 ATK), Juggernaut Liebe and Flying Launcher, powered by Night Train / Derricrane / Super Express Bullet Train Level 10 EARTH Machine chains; K9 and Infinitrack board pressure, plus Gustav Max direct damage
- Turn 1 (going first): Search with Night Train Blue Traveler and Exceptional Schedule, Normal Summon Babeldecker and Derricrane or Urgent Schedule into a Level 10 Machine line toward the Train Xyz
- Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence and Droll and Lock Bird as hand interaction, then use Regulus or Flying Pegasus negation to break the opponent's board before rebuilding through Train searchers
- Recovery: Recover Level 10 Train monsters from the GY (Night Train, Derricrane, Super Express Bullet Train) and re-enter through Double Wild and Revolving Switchyard
- After siding: Not evaluable: the deck has an empty Side Deck, so there is no post-side plan
Why it scores here
The deck's consistency rests on the searcher layer: Night Train, Exceptional Schedule, Urgent Schedule, Double Wild and Infinitrack Harvester give a probability of at least one searcher in an opening 5 of about 0.91 (Inferred). Its conversion comes from a Level 10 Train chain into Gustav Rocket and Liebe, and the Extra Deck supplies closing power, but no recorded boards exist, so the ceiling is text-only. Hand traps (Ash Blossom, Infinite Impermanence, Droll and Lock Bird) and Regulus give a going-second answer layer, but the deck is spread across Train, Infinitrack, K9, Orcust, Machina and Charmer, with 0 exact-name archetype copies, which weakens engine coherence. The listed Illegal status (three Ash Blossom, 21 Extra Deck cards) caps the score; popularity and archetype usage were not credited, and the card scores were not averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(at least one searcher in hand of 5) about 0.91 and P(Night Train in hand) about 0.27 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 17 singleton slots and a 6-card hand-trap group need a 6-card hand, so brick risk is moderate (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parseable combo boards; ceiling comes from Gustav Rocket 5000 ATK and Train Xyz text only (Inferred) |
| D4 | Combo Floor & Median Output | 45 | median output is not measured because combos_evidence has 0 boards; the score is a text-only estimate (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Train, Infinitrack and K9 offer some route redundancy, but Train is the only deep engine (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Train recursion and float-style searches from Night Train, Ruffian Railcar and Super Express Bullet Train give some grind (Inferred) |
| D7 | End-Board & Interaction Quality | 55 | 6 hand traps and 13 negation-text cards plus Regulus give a broad interaction layer (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 45 | Going-second value rests on hand traps and Droll and Lock Bird, but there is no going-second win data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Gustav Rocket at 5000 ATK, Liebe at 4000 and Flying Launcher at 3800 give strong end-board closing power (Verified card text) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 51 Main Deck cards with 17 singletons and only 0 exact-name archetype copies; off-archetype spread is 72 (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 35 | 21 Extra Deck cards exceed the OCG maximum of 15; the Extra Deck mixes unrelated archetypes (Verified legality) |
| D12 | Side Deck Adaptability | 25 | The Side Deck is empty (0 cards), so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 30 | No tournament link and no dated meta; archetype share is unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Train chains and hand-trap timing need experienced pilots; the decision load is high (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 48, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-4); dependence on one Extra-Deck card (-2); engine conflicts (-2). Final formula: Legal formula 0.80*Structural + 0.20*TournamentReliability + Modifiers = 46.4 - 8 = 38.4, capped at 30 because the list is Illegal (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.91 · 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 layer (19 searcher-text cards) gives a high chance of a functional opening
- Level 10 Train chain has strong Xyz closing power (Gustav Rocket 5000 ATK)
- Six hand traps and Regulus provide a layered going-second answer package
Weaknesses
- Illegal list: Ash Blossom at 3 copies and 21 Extra Deck cards
- Empty Side Deck means no post-side plan
- Off-archetype spread (72 of 72 non-exact copies) weakens engine coherence
Critical choke points
- Night Train or Derricrane must reach the GY to enable the Level 10 chain
- The Gustav Max and Gustav Rocket line depends on a Limited Extra Deck card
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 Ash Blossom & Joyous Spring (3 copies to 2) | Nothing; the deck becomes legal on this card | The OCG copy limit is 2 (Semi-Limited) |
| 2 | 6 Extra Deck cards: Ancient Gear Ballista, Sky Striker Ace - Kaina, Qliphort Genius, I:P Masquerena, Divine Arsenal AA-ZEUS - Sky Thunder, Gaming Gamer GG | Nothing; the Extra Deck reaches 15 | The Extra Deck maximum is 15, and these cards are off-engine for the Train plan |
| 3 | Off-archetype Main Deck slots | A Side Deck of 5 to 15 cards | The deck has no side plan, and the Side Deck is currently empty |
Evidence & confidence
- Verified: Illegal status: Ash Blossom 3 copies vs 2 legal, Extra Deck 21 vs 15; Banlist statuses for Limited and Semi-Limited cards; Card text for Gustav Rocket, Liebe, Night Train, Derricrane and hand traps; Side Deck count is 0
- Inferred: Searcher probability 0.91 in a 5-card hand; Hand-trap probability 0.55 in a 6-card hand; Engine coherence and brick risk
- Provisional: Meta power (no dated sample); Matchup fit and tournament reliability
- Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot results are absent One passcode (10443957) is unresolved and counted as a Main Deck card No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Deck has no title and an empty Side Deck
