Equip only to a Cyberse monster. If the equipped monster battles an opponent's monster, during damage calculation: You can send 1 "Mathmech" monster from your Deck to the GY; the equipped monster gains ATK equal to the sent monster's ATK, until the end of this turn (even if this card leaves the field). If this card is sent from the Spell & Trap Zone to the GY: You can target 1 "Mathmech" card in your GY, except "Mathmech Billionblade Nayuta"; add it to your hand. You can only use each effect of "Mathmech Billionblade Nayuta" once per turn.
Mathmech Billionblade Nayuta — Power Evaluation
Final Score: 48 ± 6 · Confidence: Medium
- Intrinsic: 46 · Deck: 49 · Meta: provisional
- Primary role: Recovery/Recursion · Secondary: Utility
Why it scores here
Mathmech Billionblade Nayuta is a Mathmech-focused recursion support card that recycles GY resources when sent there, fitting cleanly into the archetype's established resource engine. Despite appearing in high-power Mathmech combos (average power index 89), its combo role details are empty, indicating it functions as a supporting piece rather than a combo enabler or driver. The ATK boost effect is situational and rarely the primary value source, explaining its mid-range score despite strong deck consistency.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Consistently included in 188 decks at 1.26 copies average with searchable access through Mathmech tutors, though not self-accessible as a spell card (observed). |
| Combo & Conversion | 25 | Plays no explicitly recorded role in 3 combo appearances (all role_in_combo arrays empty); present in high-power combos as a supporting piece rather than enabler (observed). |
| Resource Economy | 60 | Effect 2 provides GY recursion of Mathmech cards for roughly neutral card economy but enables resource cycling and deck thinning (verified). |
| Effect & Interaction | 5 | Purely a support card with no opponent interaction, negation, removal, or hand-trap capability; no disruptive value (verified). |
| Material Utility | 20 | As an equip spell with no body itself, provides no independent material value; the equipped monster's material use is not unique to this card (inferred). |
| Resilience & Flexibility | 45 | Functions across multiple turns as an equip with contingent recursion on any GY send, but limited to Cyberse monsters and requires being sent to GY to trigger full value (verified). |
| Deck-Building Efficiency | 70 | Minimal deck cost with no brick risk; 1-2 copies standard in Mathmech and Cyberse restriction does not burden archetype building (observed). |
Calculation
Weight profile: 0.7 Recovery/Recursion + 0.3 Utility. Intrinsic ≈ 46, Deck ≈ 49, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Enables resource cycling and GY recursion within Mathmech's established game plan
- Exceptional 96%+ co-inclusion with core Mathmech cards (Diameter, Sigma, Final Sigma) shows tight archetype integration
- Appears consistently in high-power Mathmech combo lines (average power index 89)
- Zero brick risk; clean 1-2 copy inclusion pattern across 188 decks
- Recursion effect triggers off any GY send, providing flexibility beyond just this card's own effect resolution
Weaknesses
- No explicitly recorded role in combo evidence; functions as present-but-passive supporting piece rather than active driver
- ATK boost effect (effect 1) is situational and requires active battle phase opportunity during combo turn, rarely the primary value
- Cyberse-only equip restriction limits splashability despite appearing in 23 distinct archetypes
- Purely support/utility card with zero opponent interaction, disruption, or negation capability
- Combo role details are empty across all 3 recorded appearances; exact synergy value contributions unclear
Counters / choke points
- Negation of card effects prevents both GY recursion and ATK boost
- Removal or destruction of equipped monster ends ATK boost mid-calculation
- Cards that lock or seal the Graveyard prevent recursion engine entirely
Best use
GY recursion engine and resource support. Decks: Mathmech.
Evidence & gaps
- Verified: Equip-only to Cyberse monsters with two once-per-turn effects (damage calculation ATK boost and GY recursion on send); Appears in 188 total decks with 1.26 copies average; 71.8% in Mathmech variants; Appears in 3 recorded combos with power indices of 99, 92, and 76 (average 89); 96%+ co-inclusion with core Mathmech pieces (Diameter, Sigma, Multiplication, Final Sigma); Card text enables GY recursion of any Mathmech card except itself when sent to Graveyard
- Observed: 23 distinct archetypes include this card, but inclusion heavily concentrated in Mathmech (71.8%); All 3 combo role_in_combo arrays are empty; card is present but plays no explicitly tracked role; Average 2.67 starters per combo appearance; requires multiple-card setup; 3727 page view count indicates consistent community interest and awareness; Splashing outside Mathmech is minimal despite 23 archetype appearances; suggests Cyberse restriction is limiting factor
- Inferred: Primary role is GY recursion/resource cycling rather than combo enabling, based on effect text and deck usage patterns; ATK boost effect is secondary and situational; requires battle phase opportunity that doesn't occur during typical combo construction; Cyberse-only restriction significantly limits portability despite appearing in multiple archetype decks; Serves as supporting piece in Mathmech's established resource engine rather than as combo starter or primary enabler; High combo power indices reflect quality of Mathmech decks generally, not this card as a combo driver
- Data gaps: No banlist information provided; assumed 3 copies unlimited across all formats No StatisticsCard data available; archetype inclusion percentage and historical copies inferred from this 188-deck sample only All combo role_in_combo arrays empty; unclear what specific function card serves in the 3 recorded boards Guide coverage minimal (2 guides total, sparse functional detail on card usage) No tournament rankings or top-card context across TCG/OCG/MasterDuel/DuelLinks formats Board state details in combo evidence do not track Nayuta's specific contributions or sequencing No data on whether ATK boost effect is actively utilized in practice versus remaining dormant
