Identity & game plan

Win condition: Train/Xyz beatdown through Superdreadnought Rail Cannon Xyz monsters (Gustav Rocket, Juggernaut Liebe, Flying Launcher, Super Dora) and Crystron/Train board presence (Inferred from card text); Direct damage from Superdreadnought Rail Cannon Gustav Max (2000 damage per detach, limited to one legal copy) (Verified card text)
Turn 1 (going first): Open with Night Train / Exceptional Schedule / Urgent Schedule to reach Train Xyz and Link material; hand traps held for the opponent's first activation (Inferred)
Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Forbidden Droplet to answer the opponent's opening; rebuild through Crystron Inclusion and searchers (Inferred)
Recovery: Searchers (15 copies of searcher text) and Ancient Gear Box / Crystron Inclusion to re-find engine pieces after a disruption (Inferred)
After siding: Not evaluable: the deck has 0 Side Deck cards, so no post-side plan exists (Verified)

Why it scores here

The deck is scored as a system: its Crystron core is thin (6 exact-name Crystron copies, 8.6% purity) and it splits across Train, Infinitrack, Mulcharmy, Scrap and generic spells, so the engine is not one cohesive line. Its closing power is the strongest part, because the Superdreadnought Rail Cannon Xyz monsters reach 3000–5000 ATK and Gustav Max adds direct damage. Interaction is broad on paper (Ash Blossom, Droll, Forbidden Droplet, Harpie's Feather Duster, Heat Wave, Subspace Battle), but the illegal copy counts remove some of the strongest pieces. There is no combo, guide or tournament evidence, and no Side Deck, so the score rests on text and probability inference. Popularity of the archetype did not earn points, and the card scores were not averaged.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	45	Crystron core is 6 exact-name copies with an archetype_core_group P(open ≥1) of 0.92 but a 2-card bootstrap that is unproven; starter P(≥1 in 5) ≈ 0.25 per 3-copy card (Inferred)
D2	Opening-Hand Quality & Brick Management	40	28 Spell Cards and several 0–1 copy tech/hand traps raise brick risk; 10 three-copy cards help consistency (Inferred)
D3	Combo Conversion & Ceiling	35	No parseable boards; ceiling read from Train/Gustav Max and Xyz card text only (Inferred)
D4	Combo Floor & Median Output	30	combos_evidence reports zero boards, so the median is unknown and set low (Provisional)
D5	Interruption Resilience & Route Redundancy	40	5 hand traps plus Ash Blossom and Droll give several independent responses, but Ash and Droll are over the limit (Inferred)
D6	Resource Economy, Recovery & Grind	50	15 searcher-text cards and Crystron Inclusion recycle resources well; Gustav Max's ATK-to-damage conversion costs materials (Inferred)
D7	End-Board & Interaction Quality	50	Harpie's Feather Duster, Heat Wave, Subspace Battle, Forbidden Droplet and Book of Eclipse give layered interaction, but Called by the Grave and Triple Tactics Talent are illegal (Verified card text, Inferred quality)
D8	Going-Second & Board-Breaking Power	42	Going-second board breaking depends on Droll, Ash and Droplet, and Heat Wave is the only broad effect; no going-second split exists (Inferred)
D9	Offensive Pressure & Closing Power	60	Gustav Rocket 5000 ATK, Juggernaut Liebe 4000 ATK and Flying Launcher 3800 ATK provide high end-board pressure (Verified stat)
D10	Main Deck Efficiency & Flexibility	42	55 Main Deck cards across 31 distinct names, with 28 spells and 64 off-archetype copies, lowers coherence (Verified composition)
D11	Extra Deck Efficiency & Coverage	45	Extra Deck runs 15 cards with 9 Xyz and 6 Link, but 3 copies of Gustav Max exceed its legal limit (Verified)
D12	Side Deck Adaptability	5	No Side Deck at all, so post-side adaptability is effectively absent (Verified)
D13	Matchup Coverage & Format Fit	35	No tournament_context and no metagame sample; format fit is Provisional
D14	Pilotability & Error Tolerance	40	Chained Train/Xyz/Link sequencing and multiple hand-trap timing decisions raise the error rate (Inferred)

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (Structural weights taken from Midrange profile; Toolbox adds interaction tech, not separately blended). Structural ≈ 41, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Banlist exposure (-8); Engine conflicts and off-archetype spread (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); illegal-deck cap applied: 39 + modifiers (-12) = 27

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.25 · 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

High-ATK Superdreadnought Rail Cannon Xyz finishers
Layered interaction: hand traps, Heat Wave, Harpie's Feather Duster, Subspace Battle
Searcher density (15) supports resource recovery

Weaknesses

Illegal under OCG banlist (Forbidden and Limited overruns)
Thin Crystron core: 6 exact-name copies, 8.6% purity
No Side Deck
No combo, guide or tournament evidence

Critical choke points

Crystron core starters: too few copies to reliably open the engine
Gustav Max is the main direct-damage route and is limited to one legal copy
Hand-trap timing against the opponent's first activation

Recommended changes

Priority	Remove	Add	Reason
1	Called by the Grave (1) and Triple Tactics Talent (1)	Legal Main Deck replacements that stay in the same role (Forbidden cards cannot be run)	Forbidden cards make the list illegal; this is the blocking fix
2	2 copies of Droll & Lock Bird and 2 copies of Superdreadnought Rail Cannon Gustav Max	One copy of each, with the freed slots spent on Crystron engine cards	Brings the list within copy limits and makes the engine more coherent
3	1 copy of Ash Blossom & Joyous Spring	Legal Main Deck card for the open slot, or a Side Deck of 15 cards	Ash is Semi-Limited at 2 copies; a Side Deck is needed for post-side adaptability

Evidence & confidence

Verified: Illegal status and copy-limit violations (legality block); Forbidden/Limited status of Called by the Grave, Triple Tactics Talent, Droll & Lock Bird, Gustav Max, Ash Blossom; 55 Main / 15 Extra / 0 Side counts; Crystron exact-name purity 8.6%; Card-text effects and ATK/DEF values from the evidence pack
Inferred: Starter probabilities (hypergeometric) and brick risk; Strategy classification as Midrange with Toolbox secondary; Going-first and going-second plans; Interaction quality read from text
Provisional: Meta Power (null); Format fit (D13); Going-first and going-second split (no win-rate telemetry)
Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck has no title and no Side Deck No guides attached to the archetype
