Machina Deck #771463 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, Fusion/Xyz/Synchro
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion, Xyz and Synchro boss monsters (Ultimate Ancient Gear Golem, Chaos Ancient Gear Giant, Ancient Gear Megaton Golem, Superdreadnought Rail Cannon Flying Launcher) built from an Ancient Gear and Train board.; Ancient Gear Howitzer's 1000 direct damage per Main Phase and piercing or direct attacks from the Golem line.
• Turn 1 (going first): Open on a searcher (Ancient Gear Wyvern, Ancient Gear Dark Golem, Ancient Gear Frame, Night Train Blue Traveler or Ancient Gear Advance), search a second Ancient Gear piece, and set up a Fusion or Xyz summon on the following turn.
• Turn 2 (going second): Use the same searcher chain while answering the opponent's board with Ancient Gear Tanker, Ancient Gear Catapult and Jizukiru; no hand traps are present, so the plan depends on field interaction.
• Recovery: Recover Ancient Gear and Train monsters from the Graveyard through Night Train Blue Traveler, Ancient Gear Commander and Ancient Gear Box, and rebuild the Extra Deck boss from the remaining field material.
• After siding: Not evaluable: the deck runs zero Side Deck cards, so there is no defined post-side plan.

Why it scores here

The deck is a mostly Ancient Gear build with a Train sub-engine, and its score comes from how the system opens and converts, not from averaging card scores. Searcher density is high (19 searcher-text cards, about 97% chance of at least one in an opening hand of 5), so the engine is usually reachable on turn 1 or 2. Structural closing power is strong: the Extra Deck holds several 3800-4500 ATK bosses, and Chaos Ancient Gear Giant and Ultimate Ancient Gear Golem both carry attack-ceiling text. The main weaknesses are the absence of combo records (no boards to measure median output), a single copy of Ancient Gear Golem that is a bottleneck for several Fusion lines, zero Side Deck cards, and no hand traps or floodgates, so going-second interaction is thin. Popularity and archetype share were not available, so Meta Power is provisional and no points were given for popularity.

Dimension scores

How the score was computed

Strategy profile: 100% Midrange; Combo noted as secondary but not blended. Structural ≈ 59.5, Going First ≈ 62, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: no side deck (-2); unrecoverable choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional): 0.80*59.5 + 0.20*52 = 58.0, then modifiers -4 = 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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 package (19 searcher-text cards) gives high starter access
• High-ATK Extra Deck bosses with piercing and direct-attack text
• Multiple starters and Graveyard recursion support interruption recovery

Weaknesses

• No recorded combos, so median output and combo conversion are unmeasured
• Zero hand traps and floodgates; weak going-second interaction
• Zero Side Deck cards, so no post-side adaptation
• Off-archetype singletons (Kaiju, Orcust, Samurai, Hieratic, Super Quant) reduce main-deck coherence

Critical choke points

• Single copy of Ancient Gear Golem, required by several Fusion lines
• Fusion summons depend on specific Ancient Gear material in hand or field

Recommended changes

Evidence & confidence

• Verified: Legal in OCG: 40 Main, 15 Extra, 0 Side; no banlist violations; Card text and stats for all listed cards; Boss ATK values from card data; Zero hand traps and zero floodgates in the list
• Observed: Archetype purity: Ancient Gear 31 and Train 12 of the main deck; Usage statistics show only 4 of 19 Machina core cards present
• Inferred: Starter access ~0.97 from the searcher group (hypergeometric); Brick and garnet estimates from copy histogram and spell count; Interaction and resilience read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and format fit (no tournament link)
• Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry for this deck Meta Power is provisional without a dated metagame sample Deck title is null
