Train Deck #771464 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ancient Gear beatdown: Golem-named attackers and Fusion/Xyz finishers (Chaos Ancient Gear Giant 4500 ATK, Ultimate Ancient Gear Golem 4400 ATK, Megaton Golem 3300 ATK x2) that stop the opponent's Spell/Trap activations when attacking.; Superdreadnought Rail Cannon Flying Launcher (3800 ATK Xyz) and Howitzer's 1000-damage pings as chip damage.
• Turn 1 (going first): Normal Summon Ancient Gear Wyvern, Dark Golem or Tanker; Dark Golem and Frame search Ancient Gear pieces; Ancient Gear Advance or Statue reaches Ancient Gear Golem, then Fusion Summon a finisher.
• Turn 2 (going second): Tanker and Commander/Catapult remove a blocker; Golem attack-lock and Fortress protect the attacker; Jizukiru and Urgent Schedule provide the only negation.
• Recovery: Tanker and Babeldecker recur from the Graveyard, Schedules and Dark Golem/Box refill the hand from the Deck, and Xyz materials are reused.
• After siding: None: the deck runs zero Side Deck cards, so there is no defined post-side plan (see D12).

Why it scores here

The deck reliably opens a functional start: 9 copies of the three Normal-Summon starters (Wyvern, Dark Golem, Tanker) give an estimated 74% chance of at least one in an opening 5-card hand, and 19 searcher-text cards make a live hand very likely (Inferred). Its Ancient Gear engine is cohesive (31 of 40 Main Deck copies, though exact-name purity is only 21.8%), and multiple searchers and recursion (Tanker, Babeldecker, Schedules) support the resilience and resource scores. Conversion relies on Fusion and Xyz finishers with strong attack and piercing text, but there are no recorded boards, so the ceiling and median are text-based Inference and the floor is not measured. Points are not earned for popularity or for averaging card scores: the deck loses points for the zero Side Deck, a split between Ancient Gear and Train with thin Train core coverage, and a near-dead Extra Deck card.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63, Going First ≈ 62, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: engine_conflict_ancient_gear_vs_train (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 62.8 → 63, TR 58, pre-modifier 61.8, then −3 modifier

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Redundant Ancient Gear starters with heavy search and recursion
• Strong end-board power: Chaos Giant 4500, Ultimate Golem 4400, Launcher 3800
• Battle-phase Spell/Trap lock from Golem, Megaton, Fortress and Frame

Weaknesses

• Zero Side Deck
• Engine split between Ancient Gear and Train; Train core largely absent
• No hand traps; interaction depends on in-hand and in-field effects

Critical choke points

• Ancient Gear Golem is a single copy; Fusion and Golem-material lines depend on Advance, Statue, or Dark Golem's name change
• Seven Sins is effectively dead (needs two Level 12 monsters or a DARK Rank 10/11 Xyz)

Recommended changes

Evidence & confidence

• Verified: Legal OCG 40/15/0 with empty banlist violations; Copy histogram and card text for all 23 main and 12 extra distinct cards; Usage stat: 4 of 15 core cards present (before correction below)
• Inferred: Starter hypergeometric ≈ 0.74; Consistency, brick and interruption resilience readings; Combo ceiling from text, no recorded boards; Extra Deck castability (Seven Sins dead, Dingirsu castable with 2 Level 8)
• Provisional: Meta Power (null) and D13 format fit (neutral 50)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: meta share and pilot record absent No win-rate telemetry for going first/second, matchup, or brick/starter rates Meta Power is Provisional Evidence inconsistency: usage_statistics lists Superdreadnought Rail Cannon Flying Launcher (38354018) as in_this_deck=false, but cards[] shows 2 copies in the Extra Deck; core_cards_present is 4 and should likely be 5. Treated the cards[] list as authoritative. No Side Deck: post-side performance cannot be scored
