Ancient Gears Deck #761102 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ancient Gear board (Golem fusion and Xyz/Link extenders) into high-ATK Train and Ancient Gear beaters such as Gustav Rocket, Ultimate Ancient Gear Golem and Chaos Ancient Gear Giant; Mulcharmy and Train draw and search engines grinding card advantage while the Extra Deck threatens a late-game finish
• Turn 1 (going first): Normal Summon an Ancient Gear monster (Statue, Commander or Wyvern) or Ancient Gear Advance to search the next Ancient Gear piece, then build toward a Fusion or Xyz threat with Ancient Gear Fusion or Duel
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird and Dominus Purge to break the opponent's draw or search turn, then transition into the Ancient Gear board through Commander or Dark Golem
• Recovery: Recover through Ancient Gear Box and Night Train Blue Traveler searches and Geartown or Catapult recursion from the Graveyard
• After siding: Not assessable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens the Ancient Gear core: the proxy estimate says about 95% of opening hands (5 cards) contain at least one of the 24 archetype-core copies, and the 3-copy Ancient Gear staples give the deck a repeatable first turn (Inferred). Its interaction package (Ash Blossom, Droll & Lock Bird, Dominus Purge, Forbidden Droplet, Ancient Gear Duel, Lightning Storm, Harpie's Feather Duster) is dense and is the main source of its structural strength (Inferred from card text). Closing power is credible through several 4000+ ATK Extra Deck threats with piercing or direct-damage text. Weak points are the absence of any recorded boards, so the floor, median and ceiling are text-only inferences, and a 15-card Extra Deck spread across Xyz, Link, Fusion and Synchro with no Side Deck and a mixed sub-archetype spread (Ancient Gear 23, Train 12, Mulcharmy 6, Dominus 3, Forbidden 3, Cyber Dragon 2, Cyclone 2). The score was not produced from card popularity or usage share, and card scores were not averaged. Because the list is Illegal (Called by the Grave is Forbidden and Droll & Lock Bird is over its Limited cap), the normal Final Contextual formula is capped and this result is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 52, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); multi_subarchetype_split (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + Modifiers = 0.80*54.7 + 0.20*45 - 10 = 42.8, then capped at 35 because legality is Illegal (theoretical/structural-only, not a normal Final score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense interaction package across monsters, Spells and Traps (Ash Blossom, Droll & Lock Bird, Dominus Purge, Forbidden Droplet, Ancient Gear Duel, Lightning Storm, Harpie's Feather Duster)
• Large archetype core (24 copies) gives a high proxy probability of a functional opening hand
• Multiple high-ATK Extra Deck closers with piercing or direct-damage text
• Recursion and search engines (Geartown, Catapult, Ancient Gear Box, Night Train Blue Traveler) support recovery after disruption

Weaknesses

• Illegal as built: Called by the Grave (Forbidden) and 2x Droll & Lock Bird (Limited) break the OCG banlist
• No Side Deck, so the deck has no post-side plan and no adaptability
• No recorded boards, so combo floor, median and ceiling are unmeasured
• Sub-archetype split (Train, Mulcharmy, Dominus, Forbidden, Cyclone) lowers engine coherence
• 28 Spells with several narrow or conditional answers increase brick and dead-draw risk

Critical choke points

• Ancient Gear monsters and Golem-linked Fusion routes depend on a few copies, so losing the Commander or Dark Golem line leaves a thin rebuild
• Ash Blossom and Droll & Lock Bird are the main going-second answers and are single-point defenses if the opponent plays through them

Evidence & confidence

• Verified: Legality: Illegal (Called by the Grave Forbidden, 1 copy; Droll & Lock Bird Limited, 2 copies); Size: Main 55 (40-60), Extra 15 (max 15), Side 0 (max 15); Archetype spread: Ancient Gear 23, Train 12, Mulcharmy 6, Dominus 3, Forbidden 3, Cyber Dragon 2, Cyclone 2; Role-tag counts: hand_trap 3, tech 10, searcher_text 15, negation_text 12, removal_text 13; Usage stats: 28 rows; 15 of 24 core cards present (62.5%)
• Inferred: Opening-hand proxy: P(>=1 archetype-core card in hand5) = 0.951; 3-copy staples = 0.253 each; Going-second hand-trap access: P(>=1 of 3 hand traps in hand6) = 0.298; Interaction density is high from text roles (negation 12, removal 13) and dedicated answers; Extra-Deck closers reach 4000+ ATK with piercing or direct damage from card text; Going-first and going-second estimates from text and probabilities only
• Provisional: Meta Power (null) and matchup fit (D13) need a dated metagame sample; Tournament reliability is estimated from consistency and interaction, not from results
• 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 are absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck in the list, so the post-side plan cannot be assessed Illegal list: the normal Final Contextual formula does not apply; score is capped and theoretical
