Magnum Shield — Power Evaluation
Final Score: 42 ± 7 · Confidence: Medium
- Intrinsic: 41 · Deck: 42 · Meta: provisional
- Primary role: Utility
Why it scores here
Magnum Shield serves as a niche stat-boosting equip for Warrior decks, with solid adoption across 27 archetypes including Heroic (21.4%) and War Rock (10%). However, its zero opponent interaction, -1 resource economy, fragility to monster removal, and complete absence from recorded combo lines severely limit its power. The card provides meaningful stat amplification through its swapping effect but lacks the resilience or combo integration that would elevate it beyond an optional tech choice in Warrior mirrors.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Appears in 70 decks across 27 Warrior-focused archetypes with Reinforcement of the Army as a 61.4% partner, showing reliable Warrior-monster access in most homes (observed). |
| Combo & Conversion | 28 | Zero combos recorded and the card text shows it is a stat-boosting equip requiring an already-present Warrior monster, not a combo enabler (observed). |
| Resource Economy | 35 | As an equip spell with no searched, recursion, or refuel effects, it represents a one-time -1 card cost applied to boost an existing body (inferred). |
| Effect & Interaction | 5 | The card text contains no negation, removal, or opponent-facing interaction mechanics (verified). |
| Material Utility | 20 | As an equip spell with no material-providing effects, it relies entirely on an equipped Warrior monster for value and becomes inert if the monster is removed (inferred). |
| Resilience & Flexibility | 28 | As a single-target equip with no recursion or protection, it becomes dead if the equipped Warrior monster is removed or leaves the field (inferred). |
| Deck-Building Efficiency | 60 | Appears at 1.67 copies per deck on average with no archetype restrictions, showing it is an optional tech rather than a core staple (observed). |
Calculation
Weight profile: Utility / no clear role (default). Intrinsic ≈ 41, Deck ≈ 42, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Stat-swapping mechanic efficiently doubles monster offensive or defensive power depending on battle position
- Solid adoption across 27 Warrior archetypes with particularly strong Heroic (21.4%) and War Rock (10%) presence
- Works seamlessly with established Warrior searchers like Reinforcement of the Army (61.4% co-deck rate)
- Optional inclusion with no deck restrictions, locking mechanisms, or garnet risk
Weaknesses
- Zero opponent interaction—provides no negation, removal, disruption, or hand-trapping capability
- Complete absence from recorded combo lines despite being available in 70 decks, indicating limited role in optimal play sequences
- Fragile to monster removal—becomes dead card when the equipped Warrior is destroyed or banished
- Resource-inefficient -1 equip cost with no card advantage generation, recursion, or refuel mechanism
- Optional in all homes—only 70 decks run it and 41 of those use just 1 copy, showing marginal inclusion relative to core archetypes
Counters / choke points
- Equip spell removal (Harpie's Feather Duster, Cosmic Cyclone, Mystical Space Typhoon)
- Monster removal targeting the equipped Warrior monster
- Effect negation or dispel effects targeting the equip spell
Best use
Stat-boosting equip for Warrior mirrors and offensive trades. Decks: Heroic, War Rock, Infernoble Knight, Three Musketeers. Suggested copies: 1.
Evidence & gaps
- Verified: Card is Equip-type, Warrior-exclusive from card text; Zero opponent-facing interaction capability from card text; Used in 70 decks across 27 archetypes from deck data; Top partner Reinforcement of the Army at 61.4% co-deck rate from deck data; Assumed 3 copies unlimited (no banlist restriction) from data gaps
- Observed: 21.4% inclusion in Heroic archetype (15 of 70 decks) from deck data; Average 1.67 copies per deck with distribution: 1 copy (41 decks), 2 copies (11 decks), 3 copies (18 decks) from copies per deck; Appears across 27 distinct Warrior-focused archetypes from deck sample; Mentioned in Heroic guide's 'Vài Engines khác' section from guide data
- Inferred: Combo conversion is minimal due to card being a stat-boost equip with no combo enablement text; Resource economy is -1 (equip spell costs one deck slot with no card advantage generation); Material utility is indirect through equipped Warrior monster, not the equip spell itself; Resilience is low due to fragility to monster removal (equipped monster destroyed equals dead equip); Deckbuilding efficiency is good with no locks, restrictions, or inherent garnet risk
- Data gaps: Zero combos recorded despite 70 decks running the card—combo conversion cannot be empirically verified and is purely text-based inference No StatisticsCard usage data—archetype inclusion percentages inferred from sample of 70 decks only; larger historical sample would clarify consistency across different periods Minimal guide coverage (1 guide, brief mention)—no detailed strategic context or role description provided No banlist token—assumed unlimited to 3 copies per format; actual legal copies and current banlist status unknown
