Mathmech Deck #792407 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 41 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Link Summon a board of Cyberse Link Monsters (Firewall Dragon Singularity, Perfectron Hydradrive Dragon, Allied Code Talker @Ignister) and close with large ATK and removal from Link-points-linked monsters.; Hand-trap-supported Cyberse beatdown: stop the opponent's interaction and push Nibiru or the Link ATK line through an open board.
• Turn 1 (going first): Open a Cyberse starter (Backup @Ignister, Mulcharmy Fuwalos, Firewall Defenser or Cynet Mining to search one), Normal or Special Summon into a Link-2 or Link-3 engine, then Link Summon a big Link Monster; keep Ash Blossom and Maxx C up for the opponent's first answer.
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Maxx C and Nibiru to strip the opponent's first Summon or search, then rebuild with Cynet Mining or Lady Debug and Link Summon through the remaining space.
• Recovery: Recover from a broken first turn by searching again (Cynet Mining, Lady Debug, Backup @Ignister, Cyberse Code Magician via Cynet Ritual) and by using Mulcharmy Fuwalos draw effects; the deck has many searchers but only one or two real Link engines in the Extra Deck.
• After siding: No side deck is registered, so there is no post-side plan; this is a structural limitation in the list, not a played matchup adjustment.

Why it scores here

The deck reliably opens a Cyberse starter in most hands: there are 13 searcher or core cards and the archetype-core group has about an 87% chance of at least one copy in a five-card opening hand (Inferred). It has real interaction for a Stun-leaning shell, with two Ash Blossom, Droll & Lock Bird, Maxx C, Nibiru and Crossout Designator giving about five hand-trap or negation answers, and its Link ceiling (Firewall Dragon Singularity, Perfectron Hydradrive Dragon) is high. The score is held down because the list is illegal: two Forbidden cards (Link Decoder and Protectcode Talker) and a Limited card run over its limit, so the list cannot be played as built. No recorded boards exist, so conversion and median output are text-only estimates, and the deck has no side deck, which limits its post-side plan. Popularity of the Mathmech name was not credited, and the score was not built by averaging card scores; only 5 of 56 copies carry the exact Mathmech name, so cohesion rests on a Cyberse Link shell rather than the archetype.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 49, Going First ≈ 42, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal list: Forbidden cards in deck (-6); Copy limit exceeded (Mathmech Circular, Limited) (-2); No side deck (-2); Illegal cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*49 + 0.20*35 = 46.2; context modifiers total -10 give 36.2; Illegal legality caps the final score at 30 (theoretical / structural only)

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

• Reliable access to a Cyberse starter in opening hands (about 87% for the core group)
• Layered interaction: two Ash Blossom, Droll & Lock Bird, Maxx C, Nibiru and Crossout Designator
• High Link ATK ceiling in the Extra Deck (Perfectron Hydradrive Dragon, Firewall Dragon Singularity)
• Many searchers (13) that help recover from a broken first turn

Weaknesses

• Illegal as built: two Forbidden cards and one Limited card over its copy limit
• No side deck, so no post-side plan at all
• Low archetype purity (5 of 56 copies carry the exact Mathmech name); the engine is a mixed Cyberse shell
• No recorded boards, so the combo ceiling and median output cannot be confirmed

Critical choke points

• Link Decoder and Protectcode Talker are Forbidden; without removing them the Extra Deck cannot be built legally
• The single copies of the strongest Link Monsters (Perfectron Hydradrive Dragon, Firewall Dragon Singularity) mean one removal or hand trap can end the engine

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal (Forbidden cards and a Limited copy overrun) from the export; Main 41, Extra 15, Side 0; Copy histogram and type/attribute/race spread; Banlist status of each restricted card
• Observed: Usage data shows the Mathmech core is common (Mathmech Sigma and Mathmech Addition at 90% inclusion), which confirms the archetype is real but not that this list is strong
• Inferred: Opening-hand starter access estimate of about 0.87; Interaction density from the card text of the 7 negation and 11 removal cards; Link ceiling from Extra Deck card text; Structural score built from the Combo weight profile
• Provisional: Meta Power (null, no dated meta sample); Matchup and format fit (no tournament record)
• Data gaps: No recorded boards, so the combo ceiling, median and floor are text-only inference No tournament link, so meta-share and per-pilot record are absent No side deck list, so post-side performance is unknown No win-rate or matchup telemetry exists in the platform
