Machina Deck #768701 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 45 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck Xyz/Link boards (Superdreadnought Rail Cannon, Machina Citadel) and Train/Infinitrack recursion pressure; Machina Citadel / Machina Fortress board-breaking via Machine-tribe support
• Turn 1 (going first): Search 1 Train or Machina starter (Exceptional Schedule, Heavy Forward, Machina Redeployment) and bring a Level 10 Machine (Night Train Blue Traveler) for Xyz or Link follow-up; the line depends on the 3x Night Train and is not guaranteed.
• Turn 2 (going second): Hold Ash Blossom and Dominus Purge to stop the opponent's search or summon, then recover with Night Train or Mulcharmy Fuwalos draw effects.
• Recovery: Night Train and Heavy Freight Train Derricrane recycle Level 10 EARTH Machines from the GY; Clockwork Night and Ruffian Railcar recover searches.
• After siding: No side deck is registered, so no post-side plan exists (Inferred from the 0-card side count).

Why it scores here

The deck is scored as a system, not as an average of its cards, and it is illegal as submitted, so the Final score is capped and the result is structural only. Its searcher density (25 searcher-text cards; P(at least one searcher in a 5-card hand) about 0.99) makes it reliably open a functional hand, but the engine is split across Train (19), Infinitrack (13), Machina (6) and Mulcharmy (3) cards, with only 6 exact Machina names (10.2% purity), so the starters rarely form one line. Night Train Blue Traveler, the key Level 10 starter, is in the opening hand only about 30% of the time on the first draw. Closing power is strong because the Extra Deck carries several 3000+ ATK Superdreadnought bosses and Machina Citadel. The deck has no recorded boards, no archetype win-rate data, no tournament link and no side deck, so the combo floor and ceiling and the post-side read remain unknown. Popularity was not credited and the three-copy Ash Blossom, which is over the OCG limit, is the largest single deduction.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure_over_limit (-9); no_side_deck (-3). Final formula: Illegal cap applied: Final = 0.80*Structural(53) + 0.20*TournamentReliability(45) + ContextModifiers(-12) = 40, then capped to 30 because the deck is Illegal (theoretical/structural only; Meta Power provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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 text (25 cards) gives high opening-hand access to a starter
• Extra Deck carries several 3000+ ATK bosses with recursion routes
• Several GY recursion effects support grind after a disruption

Weaknesses

• Illegal as listed: Ash Blossom & Joyous Spring over the OCG copy limit
• Low exact archetype purity (10.2%); the engine is split across Train, Infinitrack, Machina and Mulcharmy
• No side deck, so no best-of-3 adaptation

Critical choke points

• Night Train Blue Traveler (3 copies) is the main Level 10 starter; it appears in the opening hand only about 30% of the time on the first draw
• Dependence on Level 10 EARTH Machine monsters for both Extra Deck summons and recovery

Recommended changes

Evidence & confidence

• Verified: Main 45, Extra 14, Side 0 against OCG size rules; Ash Blossom & Joyous Spring: 3 copies vs OCG limit 2 (Semi-Limited); Superdreadnought Rail Cannon Gustav Max is Limited with 1 copy run (legal); Extra Deck card stats and text for listed bosses
• Inferred: Searcher access probability about 0.99 for a 5-card opening hand; Night Train first-draw probability about 0.30; Interaction density (17 removal-text and 10 negation-text cards); Going-first and going-second splits
• Provisional: Meta Power (no dated metagame sample); Tournament reliability (no win-rate or brick telemetry); Matchup and format fit (no tournament link)
• 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 absent no win-rate telemetry (going-first, going-second, matchup, brick and starter rates) no side deck registered, so the post-side plan is unknown Meta Power is provisional without a dated metagame sample
