Train Deck #771976 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Train and Orcust Link/XYZ boards end in a large Extra Deck attacker (Gustav Max/Rocket, Regulus, Bullet Train) pushing damage through hand-trap-protected turns; Orcust recursion through Galatea-I, Longirsu and Dingirsu into repeated board presence
• Turn 1 (going first): Opening Schedule or Night Train searches, Train/Orcust Link or XYZ summon, with hand traps held for the opponent's first interaction
• Turn 2 (going second): Hold Ash Blossom, Droll and Ghost Ogre for the opponent's first starter or boss, then rebuild through Orcust GY effects
• Recovery: Mulcharmy and Scrap Recycler draws plus Orcust GY revival; Night Train from the GY is the main reboot
• After siding: No post-side plan exists: the deck has zero side cards, so every matchup is played with the main deck only

Why it scores here

The deck reliably opens a functional Orcust or Train starter about 86 percent of the time in the opening hand (hypergeometric, Inferred), and the 10 hand-trap and 15 negation-text cards give it real interruption resilience on the going-second turn. Its ceiling comes from Extra Deck boss monsters such as Gustav Rocket and Gustav Max, but no recorded boards exist, so the combo floor and median are text-only inference. Brick risk is high: only 16 of 70 archetype-tagged copies are exact Train, and 24 copies are generic or off-archetype, so many hands are functional on paper but not in the sequence they need. The deck has no side deck, so it has no post-side adaptation, and popularity was not used as evidence of power. The score is computed on the system rather than averaged from card scores, then capped low because the list is illegal.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); no Side Deck (-4). Final formula: Illegal list: theoretical/structural only. Pre-cap 0.80*52 + 0.20*40 = 49.6, then modifiers -10 gives 40, then capped at 30 for the illegal legality status.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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

• Ten hand traps and fifteen negation-text cards give going-second interaction depth
• Extra Deck boss monsters (Gustav Max, Gustav Rocket, Regulus, Bullet Train) provide strong closing power
• Draw and recursion engines (Mulcharmy, Scrap Recycler, Night Train, Orcust GY effects) support resource regrowth

Weaknesses

• Illegal copy count for Ash Blossom & Joyous Spring (3 vs 2)
• Zero side deck, so no post-side adaptation
• Low exact-archetype purity (22.9%) increases brick and conflict risk
• No recorded combo data, so consistency and median output are unverified

Critical choke points

• Night Train and the Schedule searches are the main Train starters; each is about 25 percent to appear in a 5-card hand
• Gustav Max and Gustav Rocket are each single copies, so losing them removes the main closing route
• Orcust recursion depends on Orcust monsters being in the GY, which the Orcust core only partly supplies

Recommended changes

Evidence & confidence

• Verified: Main Deck is 55 and Extra Deck is 15, both within OCG size rules; Ash Blossom & Joyous Spring is over the Semi-Limited copy limit (3 run vs 2 legal); Side Deck is empty (0 cards); Droll & Lock Bird and S:P Little Knight are Limited and run at 1 copy each (legal)
• Inferred: Opening-hand starter probability ~0.86 from hypergeometric draw estimates; Brick risk and conflict rate from archetype-purity and card mix; Interaction depth from hand-trap and negation text; Closing power from Extra Deck ATK values
• Provisional: Format fit (D13) because no dated metagame or tournament data was supplied
• 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 win-rate telemetry exists in YGOVN for going-first, going-second or matchup results Meta Power is provisional unless a dated metagame sample is supplied Side Deck is empty, so post-side performance cannot be assessed
