Diamond Dust — Power Evaluation
Final Score: 53 ± 8 · Confidence: Medium
- Intrinsic: 53 · Deck: 53 · Meta: provisional
- Primary role: Board breaker · Secondary: Removal
Why it scores here
Diamond Dust converts a board full of WATER monsters into a sweep plus 500 damage per destroyed WATER monster, so its power depends on how many WATER monsters are on the field when it resolves. The text does not limit the destruction to the opponent's side, so it can also hit the player's own WATER monsters. The card is run in 21 of the sampled decks across 12 archetypes, which confirms it is a live, portable card, but that inclusion is not treated as proof of strength. No combo evidence exists, so combo conversion and resource economy are scored from text only and kept modest.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Live as a set trap in 21 decks with about 2.24 copies each, but no searcher or search route is evidenced (observed deck count; no searched-for role data). |
| Combo & Conversion | 35 | Text-only: the damage scales with WATER monsters on the field, and no combo boards record it as a starter or payoff (inference from text; no combo evidence). |
| Resource Economy | 40 | Sweeps many cards for one trap, but it has no draw or refuel and can cost the player their own WATER monsters (inferred from text). |
| Effect & Interaction | 60 | Strong mass removal that is hard to play around when WATER monsters are present, but it is a negatable trap and works only against one attribute (verified from text, inferred for the strength). |
| Material Utility | 5 | A trap card cannot serve as material, so this axis is near zero (verified from card type). |
| Resilience & Flexibility | 40 | Set-based and negatable, with no redundancy evidence; it is useful across zones only when WATER monsters are present (inferred from text). |
| Deck-Building Efficiency | 70 | Restricted to 1-3 copies with no garnet or self-lock noted, and it appears across 21 decks in 12 archetypes (observed deck evidence; restriction inferred from text). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Removal. Intrinsic ≈ 53, Deck ≈ 53, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Mass removal across the whole field, not only the opponent's side (verified from text)
- Damage adds a finishing component after the sweep (verified from text)
- Portable across 12 archetypes and 2 gameplay types (observed from deck evidence)
Weaknesses
- Only hits WATER monsters, so it is dead against non-WATER boards (verified from text)
- Can destroy the player's own WATER monsters (verified from text)
- Set trap that can be negated (inferred from card type)
Counters / choke points
- Negation of the trap before it resolves (inferred from card type)
- Boards with few or no WATER monsters (inferred from text)

Evidence & gaps
- Verified: Text: destroys as many WATER monsters on the field as possible, then 500 damage per WATER monster destroyed and sent to the Graveyard by this effect; Card type is Trap (cannot be material); Formats: TCG, OCG, MasterDuel, DuelLinks
- Observed: Present in 21 of the sampled decks (avg 2.24 copies), 12 archetypes; Top partners: Abyss Dweller 66.7%, Effect Veiler 52.4%
- Inferred: Set trap that can be negated; Strength depends on WATER monsters on the field; Can hit the player's own WATER monsters
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies (unlimited) is assumed no usage statistics (StatisticsCard), so archetype inclusion % comes from the deck sample only
