Ancient Gears Deck #775093 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz beatdown through the Train Xyz line (Superdreadnought Rail Cannon Gustav Rocket, Flying Launcher, Super Dora, Juggernaut Liebe) supported by Machine/Train searchers and EARTH Machine recursion (Inferred from card text).; Infinitrack River Stormer and Link/Xyz follow-ups (Infinitrack Goliath, Qliphort Genius, Number 77 / Number 35 as alternate boards). Inferred from text only.
• Turn 1 (going first): Search or Special Summon EARTH Machine starters (Ancient Gear Box, Night Express/Night Train routes, Infinitrack Harvester, Ancient Gear) into Level 10 or Level 5 Machine bodies and a Train Xyz, protected by Infinite Impermanence, Ash Blossom and Effect Veiler where possible. Inferred from text.
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle, Effect Veiler, Droll & Lock Bird) to break the opponent's first summon, then Raigeki / Harpie's Feather Duster / Solemn Strike for board or backrow control and rebuild through Train GY effects. Inferred from text.
• Recovery: Recover from GY through Night Train Blue Traveler, Infinitrack Tunneller (banish, shuffle 5 EARTH Machines, draw 2), Ruffian Railcar, Infinitrack Crab Crane and Ancient Gear Box searches. Inferred from text.
• After siding: None: the deck runs 0 side cards, so there is no post-side adaptation path.

Why it scores here

The deck reliably opens a searcher line: P(at least one searcher-text card in a 5-card opening hand) is about 0.89, and the 11-copy archetype core gives about a 0.65 chance of at least one core card in hand (Inferred). Its interaction package is broad (12 hand-trap-flagged cards plus Raigeki, Harpie's Feather Duster, Solemn Strike and Infinite Impermanence), so it can contest both the first summon and the board. Its closing power comes from the Train Xyz ceiling (Gustav Rocket at 5000 ATK, Flying Launcher at 3800, Liebe at 4000). The score is not driven by Ancient Gears popularity or by averaging card scores: archetype purity is 0% exact-name, the list is split across Train, Infinitrack and generic Machines, and there are no recorded boards to measure a median. The deck is Illegal (16 Extra Deck cards against an OCG cap of 15), so the Final score is capped to a theoretical, structural-only value, and it has no side deck to adapt after a loss.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 56, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-2); dilution across sub-archetypes (-1). Final formula: Illegal (Extra 16 > 15): normal formula 0.80*Structural(54) + 0.20*TournamentReliability(45) + modifiers(-3) = 49.2, then capped to 35 as a theoretical/structural-only score. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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 (21 searcher-text cards) gives a high chance of finding a starter
• Broad, redundant interaction: Raigeki, Harpie's Feather Duster, Solemn Strike, Impermanence, Ash Blossom, Effect Veiler, Ghost Ogre and Ghost Belle
• High-ceiling Xyz finishers (Gustav Rocket 5000 ATK, Liebe 4000 ATK, Flying Launcher 3800 ATK)
• GY recursion routes give some resilience after disruption

Weaknesses

• Illegal as submitted: Extra Deck has 16 cards against a maximum of 15
• No side deck (0 cards), so no adaptation across a best-of-3
• Split archetype base (0% exact-name purity) weakens the single engine
• Tribute-dependent Level 10 and Level 5 starters create brick risk and need careful Extra Deck trimming
• Limited and Semi-Limited copies constrain legal builds

Critical choke points

• EARTH Machine tribute: many starters need one, so a hand without a Machine body is dead
• Single-copy Limited Xyz finishers (Gustav Max) and Droll & Lock Bird
• Extra Deck over the cap until one card is removed

Recommended changes

Evidence & confidence

• Verified: Extra Deck 16 cards exceeds the OCG maximum of 15 (size_warnings); Zero side deck cards; Limited/Semi-Limited copy counts are within legal limits; Main deck 60 cards within 40–60; Hypergeometric draw estimates from the evidence file
• Inferred: Midrange profile with Tempo/Toolbox secondaries from card text and composition; Consistency and brick estimates (D1, D2); Ceiling and closing power from card text (D3, D9); Interaction quality from role flags and text (D7); Going-first and going-second plans from text
• Provisional: Meta Power (null) and matchup fit (D13); Median output (D4) without recorded boards
• Data gaps: No recorded combos (total combos 0): floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record unavailable No win-rate, going-first/second split, matchup or brick-rate telemetry Meta Power is provisional without a dated metagame sample No guides attached (guide data total 0) Deck title is null
