Machina Deck #771532 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±10 · Confidence: Medium)

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

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz Summon Train/Machine boss monsters (Gustav Rocket, Super Dora, Flying Launcher) from a Train and Machina engine and convert with board-breaking effects and attacks; Machina Ruinforce and Machina Citadel as high-ATK Machine boards with removal and negation text
• Turn 1 (going first): Opening-hand Train or Machina searcher (Urgent Schedule, Machina Redeployment, Night Train Blue Traveler) into Heavy Armored Knight Babeldecker or Convex Knight, then Xyz into a 10-Level boss; the 2-card bootstrap is inferred from text only
• Turn 2 (going second): Six-card hand with a Level 10 Machine board-breaker or Ghost Sister hand trap to interrupt the opponent's Summon, then Xyz into a boss through removal text
• Recovery: Rebuild from the GY via Night Train Blue Traveler and Super Express Bullet Train recursion and Finis Terrae, plus searcher text (14 cards) to refill the hand
• After siding: Not assessable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This is a Train and Machina Xyz midrange list whose core Train and Machina searchers give it a reasonable chance to open a live Level 10 engine, but the list is illegal as built: Gustav Max is run at 2 copies against an OCG limit of 1, so the score is theoretical and structural only. Consistency is moderate, with about an 80% chance of at least one archetype-core card in the opening five, but 51 of 93 cards lie outside the exact archetype name and recorded boards are absent. Interaction is thin, with one hand trap, a few negation and removal effects, and no Side Deck to adapt. The deck does not get credit for popularity, usage statistics, or an averaged card score; the cap comes from the copy-limit violation and the Limited-card exposure.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 48.6, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-6); engine_conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list, so score is theoretical/structural only, with modifiers applied

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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 Level 10 Xyz boss options with high ATK
• Searcher text in 14 cards supports hand access
• Recursion through GY Level 10 Machines

Weaknesses

• Illegal: Gustav Max over the copy limit
• Two engines (Train and Machina) compete for slots
• Thin interaction and a single hand trap
• No Side Deck

Critical choke points

• Level 10 monster count gates most Xyz routes
• Gustav Max is Limited and cannot be legally run at 2 copies
• Single hand trap is the only going-second interruption

Recommended changes

Evidence & confidence

• Verified: Gustav Max is Limited with legal copies 1 and 2 copies run; Main 42, Extra 15, Side 0 against OCG size rules; Exact-name Machina purity is 10.5%
• Observed: No recorded combos, boards or tournament data
• Inferred: Opening-hand starter probability about 0.80; Interaction and resilience estimates from card text
• Provisional: Meta and matchup fit (no dated sample)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal, so the score is theoretical and structural only
