Ancient Gears Deck #772825 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Deck boss monsters (Superdreadnought Rail Cannon Gustav Rocket 5000 ATK, Chaos Ancient Gear Giant 4500, Ultimate Ancient Gear Golem 4400) built through Fusion, Xyz and Link lines from Ancient Gear and Train monsters; Piercing and direct damage from Ancient Gear Golem and Gustav Max (2000 direct damage per detach), supported by the spell/trap clear suite (Lightning Storm, Feather Duster, Forbidden Droplet)
• Turn 1 (going first): Search and Normal Summon Ancient Gear monsters (Wyvern, Statue, Frame, Tanker) and set up Golem access through Commander or Dark Golem; use Ancient Gear Advance to draw while building toward an extra-deck boss
• Turn 2 (going second): Clear the opponent's spells and traps or negate effects with Feather Duster, Lightning Storm or Forbidden Droplet, then convert through Fusion or Xyz bosses
• Recovery: Searchers (Wyvern, Frame, Ballista, Night Train, Exceptional Schedule) refill the hand; Clockwork Night and Geartown recur from the GY (Inferred)
• After siding: Not evaluable: the export lists no side deck (side_count 0), so there is no post-side plan

Why it scores here

The deck reliably reaches a searcher in its opening hand (P of at least one searcher in 5 cards is about 0.96, a proxy from the searcher-text group), so it usually gets a live Ancient Gear line on turns 1 and 2. Conversion is strong on paper: the Extra Deck holds several 4400 to 5000 ATK bosses and the core Extra cards are present at high inclusion, but there are no recorded boards, so the ceiling is a text-based read and the median is unmeasured. Interaction is broad for a no-hand-trap list (Lightning Storm, Feather Duster, Forbidden Droplet, Regulus, Ballista, Gustav Rocket), but the 25 non-monster main-deck slots and conditional spells (Lightning Storm needs no face-up cards, Triple Tactics needs an opponent activation) cost consistency. The score was built from the system: engine conflicts between Train and Golem tribute lines, single-copy Golem and Fusion pieces, and an empty Side Deck, not from averaging card scores. Archetype popularity and usage-core inclusion confirm the list is real and standard, but did not add points, and the missing side deck and absent meta sample hold the score down.

Dimension scores

How the score was computed

Strategy profile: 0.7 Midrange + 0.3 Toolbox. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 49. Modifiers: Engine conflicts (-3); Single-copy engine pieces (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + context modifiers (Meta provisional, no dated metagame sample): 0.80*56.4 + 0.20*49.3 - 6 = 48.98, rounded to 49

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Legal list at legal copy limits, with the Extra Deck full and matching the usage-standard core
• Searcher density gives high P(at least one searcher in opening 5)
• Extra Deck bosses with 4400 to 5000 ATK and direct or piercing damage
• Broad spell/trap and effect negation suite despite zero hand traps

Weaknesses

• No side deck, so no post-side plan and no best-of-3 adaptability
• 25 non-monster main-deck slots with several conditional spells, which raises brick risk
• Only 15 main-deck monsters, so the Golem and Fusion line rests on few bodies
• Off-archetype main cards (Forbidden, Cyclone, Harpie, Phantasm) dilute the Ancient Gear engine

Critical choke points

• Ancient Gear Golem (1 copy) is needed for the Fusion line and the Golem-based board, and its Normal Summon costs 2 tributes
• Ancient Gear Fusion (1 copy) is the only Fusion spell
• Lightning Storm needs the controller to have no face-up cards, which conflicts with a developed board

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 within size rules (ocg: main 40-60, extra 0-15, side 0-15); All Limited cards (Feather Duster, S:P Little Knight, Gustav Max) at legal copies of 1; Copy histogram and Extra Deck breakdown (6 Link, 6 Xyz, 3 Fusion) match the cards list; Usage-core presence is 23 of 24 when Extra Deck cards are counted; the export's 62.5% counts only main-deck matches
• Observed: Usage statistics show high archetype-core inclusion for Gustav Rocket, Flying Launcher, Ballista, Qliphort Genius and Chaos Giant
• Inferred: Starter reliability and brick risk from hypergeometric draws and card text; Ceiling from card text (Gustav Rocket, Chaos Giant, Ultimate Golem); Engine conflicts between Train and Golem lines; Going-first and going-second splits from text, not from recorded games
• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (no tournament link); D12 side deck adaptability (no side deck exported)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot match record absent No side deck exported (side_count 0), so D12 and any post-side plan are unmeasured Usage-stat in_this_deck flags mark Extra Deck cards (Gustav Rocket, Flying Launcher, Ballista, Chaos Giant, etc.) as missing even though the cards list includes them; the 62.5% core figure is an artifact and the real figure is about 23 of 24 No win-rate telemetry exists in YGOVN; going-first and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
