Machina Deck #769184 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 44 / Extra 13 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: No single closer. Lines end in Superdreadnought Rail Cannon Gustav Max / Machina Ruinforce / Machina Citadel boards, or Shekhinaga/Winda board pressure, all reached through the Train, Shaddoll and Machina engines in turn.; Shaddoll fusion boards (El Shaddoll Shekhinaga, El Shaddoll Winda) with negation text, plus Night Train Blue Traveler / Heavy Armored Knight Babeldecker Train searches.
• Turn 1 (going first): Search with Exceptional Schedule / Urgent Schedule / Night Train Blue Traveler / Machina Redeployment, then Special Summon an EARTH Machine (Derricrane, Dyna Base, Convex Knight) and build toward Xyz or Fusion. The plan depends on drawing the right engine piece, which is a 3-engine split.
• Turn 2 (going second): Hold Ash Blossom (illegal third copy aside) and Shaddoll Beast / Hedgehog to answer the opposing starter. Then rebuild with Shaddoll Fusion or Shaddoll Schism onto a Shaddoll Fusion monster.
• Recovery: Shaddoll Beast, Shaddoll Hedgehog, Shaddoll Hound and Naelshaddoll Ariel recur from the GY. Night Train Blue Traveler and Double Headed Anger Knuckle recover Train monsters in the GY.
• After siding: No side deck (0 cards). No post-side plan is possible as built.

Why it scores here

The deck runs three engines at once: Train (21 copies), Shaddoll (19) and Machina (5 exact-name copies, 8.8% exact-name purity). Its consistency is limited by that split, so a hand often holds a card from the wrong engine. The starter layer is reasonable: the searcher text group reaches a hand 87% of the time (Inferred), and the archetype-core group opens at least one card about 89% of the time. Recursion (Shaddoll Beast, Hedgehog, Ariel, Night Train) and the 6-Xyz plus 4-Fusion plus 3-Link Extra Deck give real grind and closing power. The deck is Illegal as built because it runs 3 copies of Ash Blossom & Joyous Spring against a limit of 2, so it does not receive a normal Final Contextual score. The rating is capped at 30 and labelled structural-only. No combo data, tournament link or side deck was supplied, so the score rests on text and probability, not measured output. Archetype popularity earned no points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Midrange secondary (structural profile only, no mixing). Structural ≈ 45, Going First ≈ 42, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); engine conflicts (-3); no Side Deck (0). Final formula: Illegal cap: 0.80*Structural(45) + 0.20*TournamentReliability(35) = 43, then modifiers -11 = 32, capped to 30 because the deck is Illegal (structural-only, no normal Final score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · 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

• Searcher density is high (14 searcher-text cards), so a hand usually finds a path.
• Recursion from the GY (Shaddoll Beast, Hedgehog, Hound, Ariel, Night Train) gives grind.
• Extra Deck of 13 offers 6 Xyz, 4 Fusion and 3 Link summon routes for many boards.

Weaknesses

• Illegal as built: 3 copies of Ash Blossom against a limit of 2.
• Three engines in one list (Train 21, Shaddoll 19, Machina 5 exact); only 8.8% exact-name purity.
• No side deck, so no post-side plan.

Critical choke points

• Opening hands that lack a searcher from the engine they need, given the three-engine split.
• Machina Citadel and Ruinforce require Machine monsters in the GY or banish zone, which early disruption can deny.
• Single-copy Shekhinaga/Winda and Gustav Max are the only high-value Extra-Deck finishers in several lines.

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom & Joyous Spring at 3 copies vs OCG Semi-Limited limit of 2; Main 44 and Extra 13 are within OCG size rules; Side is 0; Side deck is empty (0 cards); Searcher-text count 14, negation-text 8, removal-text 11, hand-trap 3 (from card text roles); Exact-name Machina purity 8.8%; archetype spread Train 21 / Shaddoll 19 / Machina 5
• Inferred: P(>=1 searcher-group card in opening 5) about 0.87 (hypergeometric); Three engines reduce consistency and raise brick risk; Shaddoll recursion and Train searches provide resilience; Extra Deck of 13 gives broad summon routes but multi-engine complexity
• Provisional: Meta Power is null and D13 is provisional: no dated metagame sample; Tournament reliability inferred from text only
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only no tournament link, so archetype meta-share and per-pilot match record are absent 1 passcode in CardIDList (20366274) could not be resolved to a card and was counted as main no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power provisional, no dated metagame sample Deck title is null
