Railway Deck #433552 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 72/100 (±5 · Confidence: Medium)

• Primary strategy: Blind-Second / OTK
• Secondary strategies: Midrange
• Format: master-duel

Legality

Main 40 / Extra 8 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Summon a high‑ATK XYZ monster (e.g., Number 81) for OTK; Control the board with hand traps and board‑wipe spells
• Turn 1 (going first): Deploy hand traps (Effect Veiler, Infinite Impermanence, Red Reboot) and board‑wipe spells (Raigeki, Dark Hole, Harpie's Feather Duster, Heavy Storm) to survive and set up turn‑2 engine
• Turn 2 (going second): Use searchers (Urgent Schedule, Revolving Switchyard, Flying Pegasus) to fetch Level‑10 Machine monsters, Xyz‑summon a big body, then attack for OTK
• Recovery: Draw engines (Tokusano Shinkyojin, Pot of Desires), Monster Reborn, and hand traps to regain resources after disruption
• After siding: No side deck; rely on hand traps and flexible main‑deck options to adapt

Why it scores here

The deck reliably opens with at least one core Level‑10 Machine monster in 96 % of opening hands, giving a solid starter. It can quickly establish a defensive wall using seven hand traps and board‑wipe spells, then on turn 2 use its searchers to summon a high‑ATK XYZ monster such as Number 81 for a potential OTK. Resource recovery is supported by draw engines and limited draw cards, though the main deck is heavy with off‑archetype filler, reducing efficiency. Lack of a side deck limits adaptability, and the deck’s success hinges on assembling the big XYZ body, making it moderately error‑tolerant. Overall the system’s consistency and second‑player pressure drive a score around the low‑70s.

Dimension scores

How the score was computed

Strategy profile: Blind-Second / OTK. Structural ≈ 72.1, Going First ≈ 65, Going Second ≈ 80, Meta = provisional, Tournament Reliability ≈ 70. Modifiers: Low archetype purity (-2); No side deck (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Very high opening‑hand consistency for core engine
• Strong OTK potential with big XYZ bodies
• Robust hand‑trap suite and board‑wipe options

Weaknesses

• Low archetype purity; many off‑archetype filler cards
• No side deck limits post‑side adaptability
• Reliance on drawing specific Level‑10 Machine and XYZ pieces

Critical choke points

• Missing a Level‑10 Machine or XYZ summon stalls OTK
• Limited draw cards (Harpy's Feather Duster, Heavy Storm, Monster Reborn, Pot of Desires) can be dead draws

Recommended changes

Evidence & confidence

• Verified: hand trap count 7 from role counts; side deck count 0 from composition
• Inferred: core starter probability 0.96 from archetype core; hand trap group probability 0.71 from hand_trap_group; engine ceiling based on XYZ OTK potential; median output based on typical turn‑2 board without big XYZ; resource recovery from draw/search cards; interaction density from role counts; going‑second pressure from hand trap probability and OTK engine; closing power from XYZ ATK values; main deck efficiency from copy_histogram and archetype purity; extra deck coverage from Extra Deck breakdown; pilotability from decision points in card texts
• Provisional: matchup coverage lacking tournament data
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
