Mathmech Deck #766445 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck pressure: Link and Xyz boss monsters (Firewall Dragon Darkfluid, Enigmaster Packbit, Transcode Talker, Accesscode Talker, Cyberse Desavewurm) reached through Cyberse and Mathmech starter chains; Mathmech Circular and Mathmech Superfactorial recursion into Synchro or Xyz follow-ups
• Turn 1 (going first): Open a Level 4 or lower Cyberse starter (Mathmech Circular, Backup @Ignister, Pikari @Ignister, Achichi @Ignister) or a searcher (Cynet Mining, A.I. Connect, Small World), reach a Link or Xyz boss, and keep Ash Blossom and Infinite Impermanence up for the opponent's response
• Turn 2 (going second): Use Droll & Lock Bird, Ash Blossom, Ghost Ogre & Snow Rabbit, Maxx C or Infinite Impermanence to break the opponent's board, then rebuild from the graveyard through Mathmech Superfactorial or Mathmech Multiplication
• Recovery: Mathmech Circular and Mulcharmy Fuwalos draw and reload from the Deck; Mathmech Superfactorial can resummon from the graveyard; Cynet Mining and Small World refill the hand
• After siding: No side deck is registered (side_count 0), so there is no post-side plan; any adjustment must come from the main deck

Why it scores here

The deck is scored as a system: a Cyberse starter layer (Circular, Backup, Pikari, Achichi, Micro Coder) and searchers (Cynet Mining, A.I. Meet You, Small World) feed a full 15-card Extra Deck of Link, Xyz and Synchro bosses. Starter access looks reasonable (hypergeometric P(at least one searcher in 5 cards) ≈ 0.87, Inferred), but only 10 of 41 main cards are exact Mathmech, so engine coherence is split across the Ignister, Code Talker and PSY-Frame lines. Interaction is the deck's clearest strength: 11 hand traps plus Cynet Conflict and the Extra Deck negations give a P(at least one hand trap in 6 cards going second) ≈ 0.87, which supports resilience and going-second play. No combos were supplied, so floor, median and ceiling are text-only inferences and the ceiling is not used as the average. Popularity and the guide mentions were not credited as strength; the score comes from consistency, interaction and Extra Deck coverage, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: approximately 85 Midrange / 15 Toolbox (Toolbox weighting used only as a tie-break on interaction and tech density). Structural ≈ 62, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Engine conflict across sub-archetypes (-2); Off-archetype dilution (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · 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

• Eleven hand traps plus Crossout Designator and Cynet Conflict give broad interaction (Verified card text, Inferred conversion)
• Full 15-card Extra Deck of Link, Xyz and Synchro bosses with ATK up to 3000 (Verified stats)
• Multiple Cyberse starters and searchers give high starter density (Inferred from probability)
• Legal in Master Duel with no copy-limit violations (Verified legality)

Weaknesses

• Only 10 exact Mathmech cards; the deck mixes Ignister, Code Talker, PSY-Frame and Firewall lines (Verified composition)
• No side deck and no post-side plan (Verified legality data)
• No combo boards, so floor and median output are unmeasured (Verified absence)
• 17 singletons and 13 tech cards increase the chance of a dead draw (Inferred)

Critical choke points

• Cyberse starter access (Circular, Backup, Pikari, Achichi, Micro Coder) is required to reach Extra Deck material
• Ash Blossom, Infinite Impermanence and Droll & Lock Bird must be held for the opponent's response, so using them early leaves the board open

Recommended changes

Evidence & confidence

• Verified: Deck is legal for Master Duel with 41 main, 15 extra and 0 side; Limited and Semi-Limited copy counts are within their caps; Exact Mathmech purity is 17.9%; Extra Deck contains 10 Link, 2 Xyz, 2 Synchro and 1 Fusion monster; Guides exist for Mathmech (titles and snippets only)
• Inferred: Starter access about 0.87 for at least one searcher in an opening hand; Interaction density is high from hand-trap and negation text; Going-second hand-trap availability about 0.87; Ceiling from Extra Deck boss ATK
• Provisional: Meta Power and D13 matchup fit, with no dated metagame sample; Side-deck adaptability, with no side deck
• Data gaps: no combos supplied: floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is provisional without a dated metagame sample usage_statistics compares only the Main Deck: Firewall Saber Dragon, Linguriboh and other Extra Deck cards that this deck runs are marked in_this_deck false, so missing_core (12 of 25 present) overstates the gap deck title is null
