Ancient Gears Deck #771461 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Fusion and Xyz beatsticks on a board of Ancient Gear monsters: Chaos Ancient Gear Giant (4500), Ultimate Ancient Gear Golem (4400), Superdreadnought Rail Cannon Flying Launcher (3800), Ancient Gear Megaton Golem (3300) and Jizukiru (3300), with piercing and spell/trap lock from Ancient Gear Golem and Megaton.; Ancient Gear Howitzer's direct damage and Number 77 as a late Xyz; Number 77 is weak because it needs two Level 12 monsters and only Superheavy Samurai Brave Masurawo is Level 12.
• Turn 1 (going first): Search with Ancient Gear Wyvern, Dark Golem, Frame or Box (19 searcher-text cards, P(at least one searcher in opening 5) = 0.97), go to Ancient Gear Golem or Commander, then Fusion or Xyz into a board.
• Turn 2 (going second): Six-card hands with a 0.39 chance of a 3-copy starter; go-second play relies on Urgent Schedule, Ancient Gear Duel and Golem lock, then Chaos Giant or Ultimate Golem to beat the board. The deck has no hand traps.
• Recovery: Tanker and Ancient Gear Box recur from the Graveyard; Geartown and Switchyard give Special Summon routes after a clear; Advance draws.
• After siding: No side deck. Best-of-3 has no post-side plan (D12 scored low).

Why it scores here

The deck opens reliably: 19 searcher-text cards and 24 core Ancient Gear copies give about a 97% chance of a searcher and a 99% chance of an Ancient Gear card in the going-first opening 5 (Inferred from hypergeometric draws). Its ceiling comes from the Golem fusion and Xyz package: Chaos Giant, Ultimate Golem, Launcher, Megaton and Jizukiru are 3300 to 4500 ATK beatsticks, and Golem and Megaton lock spells and traps during attacks. Structural score is driven by consistency, recursion and closing power on the system, not by averaging card scores. The deck has no recorded combos, so median and ceiling are text-based (Inferred). Going second is weaker because a 6-card hand has a 0.39 chance of a 3-copy starter and there are no hand traps. There is no side deck, and no tournament or win-rate data was supplied, so popularity and archetype usage did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63.7, Going First ≈ 70, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: no side deck (-2); split engine (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.8*63.7 + 0.2*56 - 4 = 58.2

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (19) gives near-certain going-first access
• Several 3300 to 4500 ATK finishers with piercing or multi-attack
• Golem and Megaton stop spell/trap responses during attacks
• Multiple independent starters and Graveyard recursion

Weaknesses

• No side deck, so no best-of-3 adjustment
• No hand traps and few negations for going second
• Number 77 needs two Level 12 monsters; only Masurawo is Level 12
• Split engine: 12 Train cards plus Kaiju and Superheavy splashes

Critical choke points

• Ancient Gear Golem is 1 copy and cannot be Special Summoned; Fusion/Xyz lines through Golem depend on Frame, Advance, Commander or Dark Golem to find it
• Level-10 material for Launcher (x2), Chaos Giant and Ultimate Golem depends on Night Train (x2), Babeldecker and Jizukiru

Evidence & confidence

• Verified: Legal OCG 40/15/0 with all cards Unlimited and no violations; All card stats and text excerpts from the evidence pack; Usage stats: 54% core present
• Inferred: Starter access 0.97 and brick rate 0.007 from hypergeometric draws; Going-second weakness from 0.39 starter odds and no hand traps; Structural weights and dimension scores
• Provisional: Meta power null and matchup fit (D13) without 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/second or matchups exact_name_purity_pct reported as 0 is a preprocessing artifact; archetype_spread used instead Deck title is null
