Machina Deck #773182 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

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

Identity & game plan

• Win condition: Xyz and Link boards that end in Superdreadnought Rail Cannon Gustav Rocket (5000 ATK) or Juggernaut Liebe, supported by the Train and Machina Machine swarm.; Gustav Max direct damage (2000 per detach) and Machina Ruinforce as a large GY-summoned body.
• Turn 1 (going first): Open a Machine or Train starter (Night Train Blue Traveler, Exceptional Schedule, Mulcharmy Fuwalos, Scrap Recycler), search or recycle through Revolving Switchyard and Ancient Gear Box, then build toward a Level 10 Xyz. Hand traps are held up but are only partly reliable without a going-second draw.
• Turn 2 (going second): Use Ash Blossom and Droll as the first interaction, then rely on Heat Wave or Pot of Sloth to recover the card advantage. The Level 10 Xyz line is the follow-up, but the deck has no real answer to a full opposing board besides the Kaiju and Heavy Armored Knight Babeldecker lines.
• Recovery: Recursion sits in the GY: Night Train, Heavy Armored Knight Babeldecker, Ancient Gear Box, and the Machine Level 10 GY summon routes. Recovery is plausible, but Forbidden and over-limit cards would not be legal to run in a real event.
• After siding: Not assessable. The deck has zero Side Deck cards, so there is no post-side plan at all.

Why it scores here

The score comes from the system, not from the card list or from Machina's popularity. The deck has a real starter base: the archetype-core group gives roughly an 87% chance of at least one core card in a 5-card opening hand, and the Train and generic Machine starters give a playable T1. Its closing power is high, since Gustav Rocket, Juggernaut Liebe and Flying Launcher all reach 3800 ATK or more. Interaction is broad, with 5 hand traps, 13 negation-text cards and 18 removal-text cards, but the Forbidden and over-limit copies make that interaction illegal as built. Floor and median output are unmeasured because no boards were recorded, so the ceiling cannot be trusted as the usual result. The deck has no Side Deck, which removes any post-side plan. The legality failure caps the score at a theoretical value, and no combos, win rates or meta data exist to support a normal Final Contextual score.

Dimension scores

How the score was computed

Strategy profile: primary Midrange, no secondary weighting applied. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 46. Modifiers: Copy-limit violations (-10); Forbidden cards present (-8); No Side Deck (-4). Final formula: Illegal cap applied to 0.80*Structural + 0.20*TournamentReliability (≈52) with -22 modifiers; theoretical/structural-only, Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · key two-card combo ≈ — · full-brick estimate ≈ 0.13 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High chance of a core card in the opening hand
• Strong Level 10 Xyz and Link closing power (Gustav Rocket, Juggernaut Liebe, Flying Launcher)
• Broad negation and removal text across the Main Deck
• Compact Extra Deck coverage between Xyz and Link lines

Weaknesses

• Illegal as built: copy-limit violations and two Forbidden cards
• No Side Deck, so there is no post-side adaptation
• Scattered sub-archetypes (1.4% exact-name purity) weaken engine coherence
• No recorded boards, so median output and combo conversion are unverified

Critical choke points

• The Level 10 Machine Xyz requirement depends on a small number of Machine monsters in the GY and Deck
• Removing Ash Blossom, Droll and Gustav Max to reach legal copy counts would reduce interaction and closing power

Recommended changes

Evidence & confidence

• Verified: Five legality violations against the OCG banlist (Ash Blossom, Droll, Called by the Grave, Triple Tactics Talent, Gustav Max); Main 55 and Extra 15 are within the OCG size rules; Side 0 is legal but gives no post-side plan; Card stats and text for Gustav Rocket, Juggernaut Liebe, Flying Launcher and Gustav Max
• Inferred: Opening-hand starter access ≈ 0.87 from the archetype-core hypergeometric estimate; Brick and interaction estimates from copy histogram and card text; Closing power inferred from Extra Deck ATK and direct-damage text
• Provisional: Format fit and matchup (no tournament link or dated meta sample); Meta Power (null)
• 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 no win-rate telemetry exists in YGOVN — going-first/second, matchup and brick rates are Inferred no Side Deck — post-side performance cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
