Mathmech Division — Power Evaluation
Final Score: 62 ± 5 · Confidence: Medium
- Intrinsic: 60 · Deck: 64 · Meta: provisional
- Primary role: Extender · Secondary: Removal / Interaction, Material body
Why it scores here
Mathmech Division is a solid extender that converts existing Cyberse presence into deeper combo lines through recursion and field extension, but it is fundamentally a supporting piece, not a combo driver—it does not appear as a starter in the sampled combos and requires a Cyberse already in the Extra Monster Zone to activate. The high ATK/DEF stats earn it no power bonus; the score reflects its reliable searchability within Mathmech (96%+ deck inclusion of Mathmech Sigma), clean Level 4 Cyberse material utility, and consistent deckbuilding footprint. The secondary ATK-halve effect provides only minor interaction when Division reaches the GY.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Mathmech Division is a Normal Summonable Level 4 with high searchability via Mathmech Sigma (96.1% co-deck rate), but it only activates its main effect after a Cyberse is already in the Extra Monster Zone (verified via card text and role analysis). |
| Combo & Conversion | 60 | Division extends established Mathmech plays by tributing one Cyberse to summon another, reaching combos with an average power index of 87.5, but it does not appear as a starter or payoff piece and requires prior board state (observed from combo role data). |
| Resource Economy | 50 | The card tributes one Cyberse to summon one Cyberse for a net-zero card count, with the GY effect providing only minor ATK reduction—roughly neutral resource economy with no inherent card advantage (verified from card text). |
| Effect & Interaction | 35 | Division's secondary effect (halve opponent's ATK until EOT when sent to GY) provides soft, temporary interaction that does not remove threats or prevent plays; the main effect has zero opponent interaction (verified from card text and low effect_interaction axis). |
| Material Utility | 70 | As a Level 4 Cyberse monster with no summon locks, Division is clean material for Cyberse synergies (Geomathmech, Code Talker, @Ignister) and retains value even when its effect is negated (verified from card text and archetype partner overlap). |
| Resilience & Flexibility | 60 | Division relies on a Cyberse in the Extra Monster Zone to activate its main effect, limiting flexibility against EMZ denial; however, the GY effect can trigger on send/discard/destruction regardless of the main effect status (verified from card text and role presence). |
| Deck-Building Efficiency | 72 | Mathmech Division is a Normal Summonable card with no deck lock or restriction, running at an average of 1.63 copies per deck (max 3) with 68.3% inclusion across Mathmech subarchetypes, indicating excellent deckbuilding efficiency in its home archetype (observed from deck distribution data). |
Calculation
Weight profile: 0.7 Extender + 0.3 Removal/Interaction. Intrinsic ≈ 60, Deck ≈ 64, Meta = provisional. Modifiers: none. Final formula: 0.40·Intrinsic + 0.60·Deck
Strengths
- High searchability and consistency within Mathmech via Mathmech Sigma and other tutors
- Clean Level 4 Cyberse body with good material utility for Geomathmech, Code Talker, and @Ignister synergies
- Generates multiple board synergies with core Mathmech pieces (Sigma, Laplacian, Superfactorial, Diameter)
- No deck lock or brick potential; well-distributed across 129+ decks in the sample with average 1.63 copies per deck
Weaknesses
- Main effect requires a Cyberse already in the Extra Monster Zone, making it a supporting extender rather than a combo starter or opener
- Secondary ATK-halve effect is situational and provides minimal disruption (only until end of turn, easily recovered)
- Cyberse-locked archetype severely limits portability; only 6% inclusion in non-Cyberse homes (Code Talker, Fire King, etc.)
- Not a featured role in the sampled combo lines (100% appearance but 0% in all role positions suggests passive support piece, not an engine driver)
Counters / choke points
- Extra Monster Zone denial (e.g., Swordsoul Strategist Longyuan, El Shaddoll Construct effects)
- Negation or removal of Cyberse monsters already on field (prevents the tribute for Division's effect)
- Anti-Cyberse floodgates restricting summons or effects
Best use
Extender / Combo enabler within Cyberse-focused midgame sequences. Decks: Mathmech, Code Talker (Cyberse hybrid), Fire King (Cyberse variant).
Evidence & gaps
- Verified: Card text: 'You can Tribute 1 Cyberse monster you control in the Extra Monster Zone; Special Summon up to 1 Level 4 Cyberse monster each from your hand and GY. If this card is sent to the GY: You can target 1 face-up monster on the field; its ATK becomes halved until the end of this turn.'; Appears in 129 total decks (129 main, 0 side) across TCG, OCG, MasterDuel, and DuelLinks; Unlimited copies in all formats (no banlist restriction); Top partner Mathmech Sigma co-appears in 96.1% of Division-containing decks
- Observed: Average 1.63 copies per deck (range 1–3); distribution: 71 decks with 1 copy, 35 with 2, 23 with 3; 68.3% inclusion across Mathmech subarchetypes (41.1% + 13.2% + 10.9% + 3.1%); 22 distinct archetypes running Division; portability ~6% in non-Cyberse homes; Appears in 100% of sampled combos (2/2) with average power index 87.5; 65.9% of Division-containing decks in gameplay type 7 (primary format)
- Inferred: Primary role: Extender (tributes 1 Cyberse to summon 1 Cyberse; typically after field establishment, not a starter); Secondary role: Weak removal/interaction via ATK halving on GY send; Requires EMZ presence to activate main effect, limiting flexibility vs. EMZ denial; Cyberse-locked effect; only Cyberse decks and Cyberse hybrids can leverage it; High Mathmech cohesion; 96.1% co-inclusion with archetype's primary searcher (Mathmech Sigma)
- Data gaps: Combo role tracking shows 100% appearance but 0% in all position categories (starter/searched/material/payoff/end-board/end-hand), indicating either a data recording limitation or that Division is a passive setup piece not captured by the role system No usage statistics (StatisticsCard) available; archetype inclusion percentage inferred from 129-deck sample only No English-language guide coverage; only 2 Vietnamese Mathmech guides mention the card
