Magnetic Field — Power Evaluation
Final Score: 58 ± 5 · Confidence: Medium
- Intrinsic: 59 · Deck: 58 · Meta: provisional
- Primary role: Recovery/Recursion · Secondary: Removal, Utility
Why it scores here
Magnetic Field is a solid support card providing consistent GY recursion for Magnet Warriors and EARTH Rock decks, with broad splashability across 24 archetypes. Its high inclusion rate (275 decks, 42.2% in Magnet Warriors) confirms accessibility and clean deck integration. However, its support role, zero combo appearances, Field Spell fragility, and lack of board-building potential prevent a higher score; it enables decks without driving them.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Highly searchable in Magnet Warriors with 100% co-occurrence with Beta The Electromagnet Warrior and consistent inclusion across 24 archetypes; constrained by Field Zone one-at-a-time limit. (verified) |
| Combo & Conversion | 45 | Provides one GY Magnet Warrior summon plus conditional bounce, with no board inflation or combo initiation; zero recorded combo appearances indicate it serves a support role, not a combo driver. (verified) |
| Resource Economy | 60 | GY recursion of Magnet Warriors combined with soft bounce effect provides modest card advantage in attrition; roughly neutral to slightly positive swing with no net loss. (inferred) |
| Effect & Interaction | 55 | Bounce returns opponent's monster to hand only after a non-destructive battle; soft removal and situational disruption, not hard interaction. (verified) |
| Material Utility | 5 | Field Spell cannot be used as monster material; essentially no material utility whatsoever. (verified) |
| Resilience & Flexibility | 50 | Field Spell persists in Field Zone but is fragile to Field Spell destruction or replacement; Effect 1 activation depends on EARTH Rock Lv4 or lower monster in play. (verified) |
| Deck-Building Efficiency | 78 | Splashable in EARTH Rock decks with no garnet or locking risk; average 1.39 copies per deck (69% run 1, 24% run 2, 7% run 3) confirms clean, flexible inclusion. (observed) |
Calculation
Weight profile: 0.7 Recovery/Recursion + 0.3 Removal. Intrinsic ≈ 59, Deck ≈ 58, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Consistent GY recursion for Magnet Warriors and EARTH Rock decks enables resource extension
- Splashable across 24 distinct archetypes with no deck restrictions or garnet risk
- Clean integration: no locking clauses, no competing activation requirements
- Soft bounce disruption on battles provides additional value against board stress
Weaknesses
- Field Spell vulnerability: one destruction or replacement negates all value
- Effect 1 (GY special summon) requires EARTH Rock Lv4 or lower monster in play; deck-dependent activation
- Bounce is conditional on non-destructive battle; situational disruption with low guaranteed impact
- Not a combo starter or board builder; primarily a support/tutor piece
- Zero combo board appearances in recorded evidence; no evidence of driving combo wins
Counters / choke points
- Field Spell destruction (Cosmic Cyclone, Harpies' Feather Duster, Red Dragon Archfiend)
- Field Spell replacement (MST, competing Field Spells like Swordsoul Strategist Longyuan)
- Opponent battle avoidance if bounce is not strategically beneficial
- Negation on GY summon activation (Ash Blossom & Joyous Spring, Infinite Impermanence)
Best use
Recursion engine with soft battle disruption. Decks: Magnet Warriors, Adamancipator, Fiendsmith, EARTH Rock variants.
Evidence & gaps
- Verified: Card text: GY special summon of Lv4 or lower Magnet Warrior (once per turn) + bounce of unbattled-destroyed monster to hand (once per turn, end of Damage Step); 275 total decks run this card with 42.2% in Magnet Warriors primary archetype; 100% co-occurrence with Beta The Electromagnet Warrior confirms core Magnet Warriors synergy; Field Spell type inherently vulnerable to Field Spell destruction and replacement; Average 1.39 copies per deck; distribution: 69% run 1, 24% run 2, 7% run 3
- Observed: 24 distinct archetypes include this card, indicating splashability beyond Magnet core; Top 5 archetypes are Magnet Warriors (69.1%), Adamancipator (8.7%), Magnet Warrior variants (6.2%), Fiendsmith (2.9%), Naturia (1.8%); Recency: deck inclusion from 2021-11-27 to 2026-09-26 (consistent over 5+ years)
- Inferred: GY recursion enables Magnet Warriors resource loops and maintains board presence through card loss; Bounce provides soft removal and tempo advantage in attrition-based gameplay; Effect 1 activation is conditional on deck composition but reliable when setup is met; Field Spell status makes it searchable via Field Spell searchers native to EARTH Rock decks
- Data gaps: No combos supplied — combo conversion is text-only inference; zero combo appearances limit evidence of actual board initiation or extension power No guides supplied — no human expert context on usage patterns or typical impact in tournament play No banlist token — assumed unlimited (3 copies); no format-specific restrictions confirmed No usage statistics (StatisticsCard) — archetype inclusion rates and typical copies inferred from 275-deck sample only, not historical dataset
