Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Extra Deck Xyz/Link beaters (Gustav Rocket, Juggernaut Liebe, Flying Launcher, Machina Ruinforce) reached through Train and Crystron searches; no recorded board confirms a closing line; Gustav Max 2000-damage pings and Ancient Gear Ballista/Goliath-style Link and Xyz chains, none of which are fully supported by the core list
  • Turn 1 (going first): Search with Night Train Blue Traveler or Exceptional Schedule, summon a Level 10 Machine, and go to Xyz/Link; Heat Wave and Subspace Battle are the only non-engine turn-1 options and both cut into the deck's own summons
  • Turn 2 (going second): Hold Ash Blossom, Droll, and Forbidden Droplet for the opponent's first search or Special Summon, then use Harpie's Feather Duster or Called by the Grave to clear backrow; the Ancient Gear core that would make this plan consistent is largely absent
  • Recovery: Recycle Night Train and Infinitrack Tunneller from the Graveyard and rebuild a Level 10 Machine; the list has no reliable recovery for Spell/Trap or monster removal beyond the Graveyard and search effects
  • After siding: Not applicable: the deck has no Side Deck cards, so there is no post-side plan

Why it scores here

This deck is capped low because the list is illegal in OCG: five cards exceed their copy limit, including two Forbidden cards (Called by the Grave and Triple Tactics Talent), so the score is a structural-only estimate and not a normal Final Contextual score. The structural read comes from the system as a whole, not from averaging card scores: the Train engine (Night Train, Exceptional Schedule, Urgent Schedule) and the Ancient Gear and Crystron and Kaiju and Therion lines share a list but do not reinforce each other, and the Ancient Gear core is only 8 of 24 tracked core cards (33%). Interaction is the deck's strongest area, with three Ash Blossom, three Forbidden Droplet, Harpie's Feather Duster, and five hand traps giving a 45% chance of at least one hand trap in a going-second six-card hand, but this is partly offset by Heat Wave, which stops the deck's own Effect Monster summons. Extra Deck threats are high-ceiling but have no recorded boards, and popularity (the archetype stat rows) confirms only that the archetype is real, not that this list is strong. The side deck is empty, so there is no way to adapt after game one.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 40 P(>=1 Night Train or Exceptional Schedule-type starter in 5 cards) is about 0.81 for the searcher group, but the starters split across Train, Crystron, and Kaiju lines (Inferred)
D2 Opening-Hand Quality & Brick Management 35 Heavy 0-level spell count (28 Spells), one copy each of many engine pieces, and a Heat Wave that conflicts with the deck's own summons point to frequent dead hands (Inferred)
D3 Combo Conversion & Ceiling 40 No parseable boards; ceiling is text-only, such as Gustav Max and Liebe Xyz lines and Ballista Link lines (Inferred)
D4 Combo Floor & Median Output 30 No recorded combo distribution; median is unknown and assumed weak given the split engines (Provisional)
D5 Interruption Resilience & Route Redundancy 40 Three independent routes (Train search, Crystron search, Kaiju/Therion summon) give some redundancy, but no route is protected from one broad interruption (Inferred)
D6 Resource Economy, Recovery & Grind 40 Night Train and Infinitrack Tunneller recursion and Carnot/Regulus summons give some grind; no Graveyard-to-board loop is supported (Inferred)
D7 End-Board & Interaction Quality 55 Three Ash Blossom, three Forbidden Droplet, Harpie's Feather Duster, and Droll are strong interaction, but their copy counts are over limit (Verified text, Inferred weight)
D8 Going-Second & Board-Breaking Power 45 Going-second hand trap probability is 0.452 for six cards; no going-second combo data (Inferred)
D9 Offensive Pressure & Closing Power 50 Gustav Rocket (5000), Liebe (4000), and Ruinforce (4600) give closing power, but each is a single copy or over the limit, and no end-board data exists (Verified stats, Inferred)
D10 Main Deck Efficiency & Flexibility 35 31 distinct Main Deck cards with 17 singletons and 28 Spells across mixed sub-archetypes; low compactness and coherence (Verified composition, Inferred)
D11 Extra Deck Efficiency & Coverage 45 15 Extra cards (9 Xyz, 6 Link) with three copies of Gustav Max over the limit and no Ancient Gear Link or Xyz core in place (Verified composition)
D12 Side Deck Adaptability 10 Zero Side Deck cards, so there is no post-side adaptability (Verified composition)
D13 Matchup Coverage & Format Fit 30 No tournament link or dated meta sample; fit is provisional (Provisional)
D14 Pilotability & Error Tolerance 40 Multiple engines and decision points (Level 10 Machine searches, Xyz Summon routing, Heat Wave timing) raise error rate (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 39, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); engine_conflicts (-5). Final formula: Illegal list: structural-only. Unmodified 0.80*39 + 0.20*35 = 38.2, less context modifiers of -11 gives 27, then capped to 20 for illegal copy/banlist violations. Meta Power is null (provisional).

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.81 · 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

  • Strong interaction density: three Ash Blossom, three Forbidden Droplet, Harpie's Feather Duster, Droll, and Heat Wave-style effects
  • High searcher density (15 searcher-text copies), so a 5-card going-first hand has about an 81% chance of a search or starter
  • Extra Deck closing power from Gustav Rocket (5000 ATK), Liebe (4000), and Ruinforce (4600)

Weaknesses

  • Illegal list: five copy/banlist violations, including two Forbidden cards
  • Fragmented engines: Train, Crystron, Kaiju, and Therion lines do not share a clear core, and only 33% of the archetype core is present
  • No Side Deck and no recorded boards, so neither adaptation nor combo ceiling can be verified
  • Heat Wave and other self-restrictive cards cut into the deck's own summons

Critical choke points

  • Night Train Blue Traveler and Exceptional Schedule as the only Train searchers; without them the Level 10 Machine and Xyz routes stall
  • Gustav Max as the only Train Xyz bridge, which is over the copy limit as built
Priority Remove Add Reason
1 Called by the Grave and Triple Tactics Talent Legal OCG-playable replacements for the Toolbox slots (for example, one additional searcher or a second hand trap) Forbidden cards make the list illegal; this is a hard requirement before any normal score applies
2 One Superdreadnought Rail Cannon Gustav Max, one Droll & Lock Bird, one Ash Blossom & Joyous Spring Legal copies or a different single-copy card Brings copy counts within the Limited and Semi-Limited limits
3 Heat Wave A card that does not stop the deck's own Effect Monster summons Removes the engine conflict with 24 Effect Monsters
4 None (add Side Deck) A 10-15 card Side Deck for the most common opposing engines A zero-card Side Deck leaves no post-side adaptability (D12 = 10)

Evidence & confidence

  • Verified: Illegal status: five over-limit or Forbidden violations (legality block); Main 55, Extra 15, Side 0; Main within 40-60 and Extra within 0-15 size rules; Core-card presence 8 of 24 (33.3%); exact-name purity 0%; Hypergeometric probabilities as supplied (for example, 0.2529 for 3 copies in hand5, 0.8108 for searcher group, 0.4518 for hand traps in hand6)
  • Observed: Archetype usage stats: 28 rows with Ancient Gear core inclusion percentages (usage_statistics)
  • Inferred: Engine fragmentation across Train, Crystron, Kaiju, and Therion lines; Brick risk from 28 Spells and 17 singletons; Interaction strength from Ash Blossom, Forbidden Droplet, Harpie's Feather Duster, and Droll; Heat Wave self-conflict; Going-first and going-second power estimates
  • Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit
  • 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 are absent No win-rate telemetry; going-first/second, matchup, and brick rates are Inferred or Unknown No guides for the archetype (guides_evidence total 0) Deck title is null, so the list is identified only by its id and archetype
