Earth Machine Deck #198101 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link/Synchro bosses (Knightmare Unicorn, Saryuja Skull Dread, Therion King Regulus, Baronne de Fleur) pressing with 2800-3000 ATK once a 2-monster link line is live; Backrow-protected board (Mirror Force x3, Mirror Force Launcher x3, Starlight Road x2) that trades for the opponent's attack or activation and lets the link line keep going
• Turn 1 (going first): Open a monster and a second monster (about 53% of going-first 5-card hands) to Link or Normal Summon into a Link-2 engine; hold Mirror Force for the first attack
• Turn 2 (going second): Use Mirror Force, Mirror Force Launcher, Harpie's Feather Duster or Starlight Road to clear the opponent's first board, then rebuild with Quillbolt Hedgehog or Deskbot 001 recursion from the GY
• Recovery: Special Summon Quillbolt Hedgehog or Deskbot 001 from the GY, use Machina Overdrive from the GY, and search the next starter with Metaverse, Sacred Scrolls or Foolish Burial
• After siding: No side deck is registered (side 0) and Master Duel ranked play is single-game, so there is no post-side plan; D12 is scored structurally low

Why it scores here

This list opens a live engine only about half the time: with 13 main-deck monsters in 40 cards, P(at least 2 monsters in a 5-card going-first hand) is about 0.53, rising to about 0.65 going second, which is the bottleneck for the 12 Link and 3 Synchro extra-deck cards. Its strength is on the system, not the cards: 27 spell/trap cards, 6 negation-text cards, and 19 removal-text cards give the deck a layered, mid-to-long-game interaction package that holds up against a first board better than it closes. Consistency is held back by 3 Lava Golem that need two opposing monsters to Special Summon, by only 3 Tuners in the main deck (for 3 Synchro extras), and by a list that shares only 2 of the archetype's 25 standard core cards, so the usage statistics confirm this is a real build but not the archetype-standard one. Popularity and archetype share did not earn points, no tournament or meta data is present, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 46.2, Going First ≈ 46, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Engine conflicts and thin monster count (-3); Archetype core absence (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample): 0.80*46.2 + 0.20*38 - 5 = 39.6, rounded to 40

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered backrow and negation package (Mirror Force x3, Mirror Force Launcher x3, Starlight Road x2, Harpie's Feather Duster)
• Link-2 flexibility across Progleo, Spright Elf, Pentestag and Knightmare Cerberus
• Strong boss ceiling (Link and Synchro bosses at 2200-3000 ATK)
• Complete, legal list with all restricted cards at one copy

Weaknesses

• Only 13 main-deck monsters for a link-heavy extra deck
• 27 spell/trap cards and 3 Imperial Iron Wall lower brick-free consistency
• 3 Lava Golem need the opponent to control 2 monsters
• Structurally off the archetype's standard core (2 of 25 cards)
• No side deck

Critical choke points

• Reaching the first 2-monster Link material on going-first hands (about 53%)
• Having a main-deck Tuner available for Synchro and Quillbolt recursion (3 Deskbot only)

Recommended changes

Evidence & confidence

• Verified: Legal: 40 main, 15 extra, 0 side within size rules; 3 Limited cards at one copy each; Card text for all listed cards from evidence; Archetype usage: 2 of 25 core cards present
• Inferred: Hypergeometric draw rates: 0.88 at least one monster, 0.53 at least two monsters in going-first hand; Engine and brick assessment from composition; Recursion and interaction density read from card text
• Provisional: Meta and format fit (D13); Tournament reliability inputs without tournament data
• Data gaps: Deck title is null No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry: going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample No side deck, so post-side adaptability is unmeasured
