Earth Machine Deck #770376 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: master-duel

Legality

Main 60 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Train/Machine Xyz or Link OTK: Night Train Blue Traveler and Exceptional Schedule enable Level 10 EARTH Machines, which feed Superdreadnought Rail Cannon Gustav Max and Gustav Rocket for direct damage and board-clearing pressure.; Machina and Infinitrack board pressure (Machina Ruinforce, Machina Citadel, Infinitrack River Stormer) when the Train line is disrupted.
• Turn 1 (going first): Turn 1 Heavy Forward or Machina Redeployment to search a Level 10 EARTH Machine or Train enabler, then Night Train or Heavy Armored Knight Babeldecker into a Level 10 Train Xyz.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, and Maxx C to answer the opponent's first summon or search, then rebuild the Train line from the GY through Night Train and Vernusylph recursion.
• Recovery: Vernusylph and Infinitrack recursion (Road Roller, Trencher, Tunneller) plus Night Train from the GY to rebuild Level 10 EARTH Machine material.
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot change its matchup plan between games.

Why it scores here

The deck reliably opens a Level 10 EARTH Machine line: P(at least one searcher-text card in a 5-card opening hand) is about 0.96, and Night Train, Exceptional Schedule, Heavy Forward, Harvester and Redeployment each carry three copies. Its conversion ceiling is high because the 15-card Extra Deck has Gustav Max, Gustav Rocket, Liebe, Super Dora and AA-ZEUS, which together produce 3000 to 5000 ATK pressure, and the 5 hand traps give it real interaction on both turns. It is held back by a sprawling four-archetype build (Train 22, generic 16, Infinitrack 13, Machina 8, Vernusylph 6 copies off the Earth Machine name), 21 singletons and several dead-in-hand spells, which lower brick management and median output. It has no side deck, so it earns nothing for post-side adaptability. Popularity in the archetype's usage statistics confirms the list is real and accessible but did not add points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64.4, Going First ≈ 66, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Engine conflicts across sub-archetypes (-3); No side deck (-2); Limited banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*64.4 + 0.20*50 - 6 = 55.5, rounded to 56

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Multiple 3-copy starters (Night Train, Exceptional Schedule, Heavy Forward, Harvester, Redeployment) give high first-hand access.
• A full 15-card Extra Deck of high-ATK Train and Machina Xyz/Link threats with direct-damage and board-clearing options.
• Five hand traps and layered negation text cover both turns of play.

Weaknesses

• Four sub-archetypes (Train, Infinitrack, Machina, Vernusylph) with 75 off-name copies dilute the engine and raise brick risk.
• Roughly ten dead-in-hand or off-plan spells (Thrust, Talent, Subspace Battle, Clockwork Night, Grass Looks Greener) lower consistency.
• No side deck means there is no post-side plan.

Critical choke points

• Level 10 EARTH Machine material: Night Train and Gustav Max both depend on having a Level 10 EARTH Machine in hand or GY, so losing that body to a single removal or Ash Blossom line stops the Train plan.
• Limited and Semi-Limited staples (Maxx C, Crossout Designator, Droll & Lock Bird) cap how much hand-trap redundancy the deck can carry.

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 60 Main, 15 Extra, 0 Side; four restricted cards within their limits (Crossout Designator, Maxx C, That Grass Looks Greener, Droll & Lock Bird).; Card text, ATK/DEF and Level for all 60 Main and 15 Extra cards, from the resolved card list.; Copy histogram (21 singletons, 12 doubles, 5 triples) and the Extra Deck split of 9 Xyz and 6 Link.
• Inferred: P(at least one searcher-text card in hand5) ≈ 0.96 and P(full brick) ≈ 0.06.; Strategy is Combo (Train Xyz OTK) with Midrange and Toolbox secondaries, from Extra Deck structure and card text.; Ceiling and median ratings based on text-only reads of the Level 10 Train and Machina lines.; Interaction quality and going-second board breaking from card text.
• Provisional: Meta power is null; no dated metagame sample exists.; Matchup and format fit rely only on guide text, not on tournament results.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. usage_statistics.in_this_deck is false for 11 core cards that appear in the Extra Deck list (Flying Launcher, Double Headed Anger Knuckle, Gustav Rocket, Juggernaut Liebe, Super Dora, Qliphort Genius, Clockwork Knight, River Stormer, AA-ZEUS, Ancient Gear Ballista, Gustav Max). The usage matcher appears to check only the Main Deck, so the core_present_pct of 56 understates the real coverage; this evaluation uses the card list. No tournament link: archetype meta-share and per-pilot match record are absent. No win-rate telemetry: going-first/second, matchup, brick and OTK rates are unknown or Inferred. No side deck, so post-side performance cannot be scored. Meta Power is provisional unless a dated metagame sample is supplied.
