Ancient Gears Deck #767646 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Extra Deck Xyz/Link boards (Superdreadnought Rail Cannon Gustav Rocket and Flying Launcher, Night Train Blue Traveler / Heavy Armored Knight Babeldecker Level 10 engine) overwhelming the opponent's board; Gustav Max direct damage and recursion into a 5000 ATK Rocket; Ancient Gear Ballista removal
• Turn 1 (going first): Night Train Blue Traveler and Urgent/Exceptional Schedule to fetch Train Level 10 pieces, Babeldecker and Gustav Max Xyz, with Ash Blossom and Droll to protect the first line; the list has no verified starter count, so this is Inferred
• Turn 2 (going second): Hand traps (Ash Blossom, Droll & Lock Bird) and Harpie's Feather Duster or Forbidden Droplet to answer the opponent's board, then Train Xyz/Link summons from the remaining resources
• Recovery: Night Train Blue Traveler and Revolving Switchyard recursion from the GY, Heavy Armored Knight Babeldecker Special Summon, and Infinitrack Tunneller draw from GY Machines
• After siding: Not evaluable: the deck has no Side Deck (side_count 0)

Why it scores here

The list is Illegal under OCG copy limits: it runs 3 Ash Blossom, 2 Droll, 1 Called by the Grave and 1 Triple Tactics Talent (both Forbidden), and 3 Gustav Max, so it is scored structurally only and capped at 20. Its core engine is a Train/Machina-style Level 10 and Xyz/Link package with a reasonable 15-card Extra Deck and roughly 81% hypergeometric odds of at least one archetype-core card in a going-first 5-card hand, which supports a moderate consistency read. Its recorded combo evidence is empty, so ceiling and median output are text-only inference and neither is strong. The deck has no Side Deck, and no tournament or meta data exists, so going-second and matchup scores stay low. Popularity was not used and card scores were not averaged; the score reflects the system's structure and its legality failure.

Dimension scores

How the score was computed

Strategy profile: ~85% Midrange / 15% Toolbox. Structural ≈ 44, Going First ≈ 45, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (copy-limit violations) (-8); No Side Deck (-2); Archetype purity (-2). Final formula: Illegal deck: 0.80*Structural(44) + 0.20*TournamentReliability(35) = 42 before modifiers, then capped at 20 as theoretical/structural-only; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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

• Archetype core group has ≈81% at-least-one in a going-first 5-card hand
• Five hand traps plus Harpie's Feather Duster and Forbidden Droplet give layered interaction
• Level 10 Machine and Xyz pieces (Gustav Rocket, Super Dora, Flying Launcher) provide closing power if reached

Weaknesses

• Illegal under OCG copy limits: 5 cards over limit or Forbidden
• No Side Deck, so no post-side adaptation
• Archetype identity is diluted: exact Ancient Gears purity is 0%
• No recorded combos, so the ceiling and median are unverified

Critical choke points

• Gustav Max and Night Train Level 10 access, since Gustav Max is over-limit and Forbidden or Limited cards must be replaced
• Dependence on hand traps Ash Blossom and Droll, both over the copy limit

Recommended changes

Evidence & confidence

• Verified: Illegal status: 5 copy-limit violations under OCG banlist; Main 55 and Extra 15 are within OCG size rules; Side count is 0; Usage stat: 8 of 24 core cards present (33.3%)
• Inferred: Consistency estimates from hypergeometric draw odds; Going-first and going-second read; Combo and interaction layer read from card text
• Provisional: Meta power and matchup fit: no tournament or dated meta data
• 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 for going-first, going-second, matchups or brick rate Meta Power is Provisional unless a dated metagame sample is supplied
