Mask of Weakness — Power Evaluation
Final Score: 30 ± 6 · Confidence: Medium
- Intrinsic: 36 · Deck: 32 · Meta: provisional
- Primary role: Board breaker / Going-second
Why it scores here
Mask of Weakness is a narrow, reactive trap that addresses only attacking monsters. While its ATK reduction provides soft disruption on the opponent's turn, the effect is modest (700 ATK affects few meta threats decisively) and requires specific board state to function. It appears in only 4 decks, mostly Amazoness, with no observed combo interactions or guides endorsing broader use. The card trades a deck slot for situational mitigation without generating advantage or enabling win conditions.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Requires both a set trap and an opponent's attacking monster to function, making it conditional and narrow (verified) |
| Combo & Conversion | 15 | Does not build boards, extend combos, or generate card advantage as a purely defensive reactive card (verified) |
| Resource Economy | 20 | Consumes one deck slot with no return, refuel, or search capability (verified) |
| Effect & Interaction | 45 | Reduces attacking monster ATK by 700, a modest and soft form of disruption that does not prevent effects (verified) |
| Material Utility | 5 | Trap Card with no stats, level, or type synergy for material-based play (verified) |
| Resilience & Flexibility | 25 | Can survive until the opponent's turn as a set trap but only functions against attacking monsters, limiting its application window (inferred) |
| Deck-Building Efficiency | 35 | Appears in only 4 decks (2 Amazoness, 2 misc) as a 1-of, indicating low adoption and niche applicability (observed) |
Calculation
Weight profile: Board breaker / Going-second primary role. Intrinsic ≈ 36, Deck ≈ 32, Meta = provisional. Modifiers: Narrow application scope (-2); Minimal deck representation (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clear, unambiguous card text with no complex timing interactions
- Can be set and activated reactively from the hand
- Provides mitigation against high-ATK attackers in defense-focused strategies
Weaknesses
- Extremely narrow trigger condition: only works on attacking monsters
- Modest effect: 700 ATK reduction is insufficient against many meta threats (1500+ ATK bodies)
- No card advantage or deck acceleration; pure −1 resource
- Dead card against non-attacking boards or defensive meta strategies
- No synergy with modern combo-driven decks; only appears in Amazoness and misc
Counters / choke points
- Decks that don't attack (control/stall strategies)
- High-ATK monsters where 700 reduction is irrelevant (3000+ ATK bodies)
Best use
Defensive anti-attack tech in go-second strategies. Decks: Amazoness, Fusion-focused Mask decks. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: 'Target 1 attacking monster; that target loses 700 ATK until the end of this turn'; Appears in 4 total decks (2 Amazoness, 2 misc); 1 copy per deck in all observed instances; No combos recorded in evidence
- Observed: 50% deck representation split between Amazoness and unarchetype'd strategies; Polymerization is top partner (75% co-deck rate), suggesting Fusion-focused decks; Limited adoption across only 4 decks from 2023–2026
- Inferred: Reactive trap functioning as a going-second defensive tool; 700 ATK reduction is modest mitigation (insufficient against 1500+ ATK threats); No self-searching or deck-thinning capability; Designed for Mask archetype synergy (per name and archetype tag)
- Data gaps: No combos supplied — trap card interaction is purely text-based; cannot verify combo conversion empirically No guides supplied — no authoritative deck-building context available No usage statistics (StatisticsCard) — deck sample is minimal (4 total); archetype inclusion % is estimate-only No banlist token — assumed unlimited (3 copies) across all formats
