Why it scores here
Wattcastle is a Field Spell whose only effect is that a monster attacking a Watt monster loses 1000 ATK after damage calculation. It does not stop the attack or its damage, it converts nothing into board, cards, or advantage, and it only matters when a Watt monster is attacked. The score comes from the card's cheap, clean deckbuilding and its persistence as a field card; no deck, combo, or guide evidence was supplied, so the result is provisional and the card's Final score is its Intrinsic score alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 30 | Field Spell in the Watt archetype with no searcher, deck, or combo evidence to confirm how often it is reached (inferred). |
| Combo & Conversion | 15 | Does nothing on its own and builds no board; no combo examples were supplied (verified: card text). |
| Resource Economy | 10 | No draw, search, banish, or recursion; the effect is a post-battle ATK penalty, not card advantage (verified: card text). |
| Effect & Interaction | 25 | Soft, one-sided penalty that applies only after damage calculation and only to attacks on Watt monsters, so it does not prevent damage (verified: card text). |
| Material Utility | 5 | A Spell Card cannot be used as material, so it contributes nothing here (verified: card type). |
| Resilience & Flexibility | 40 | Persists in the Field Zone until destroyed, but no removal or interaction evidence was supplied (inferred). |
| Deck-Building Efficiency | 80 | Single-zone, low-cost card with no garnet or lock restriction; legal copies for each format were not supplied, so 3 copies is assumed (inferred). |
Calculation
Weight profile: Utility / no clear role (default) single-role weights; no secondary blend applied. Intrinsic ≈ 33, Deck ≈ —, Meta = provisional. Modifiers: none. Final formula: Final = Intrinsic (no decks and no combos supplied; provisional; Deck = null)
Strengths
- Cheap, single-copy field card with no garnet or lock restriction
- Persists in the Field Zone and punishes attacks on Watt monsters without costs
- Legal in all four listed formats
Weaknesses
- Does not prevent the attack or its damage; only an ATK reduction after damage calculation
- Only triggers when a Watt monster is attacked, so its value depends on the Watt board
- No card advantage, search, or board creation
- Occupies the Field Zone
Counters / choke points
- Field-spell destruction or Field Zone wipe effects (inferred)
- Attacks aimed at non-Watt monsters or at the player, which the effect does not touch (verified: card text)
Best use
Field-spell deterrent for Watt monsters. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: any monster attacking a Watt monster loses 1000 ATK after damage calculation; Card type: Spell Card, frame spell, race Field; Formats listed: TCG, OCG, MasterDuel, DuelLinks
- Inferred: Field Spell persists until destroyed; Attacks on Watt monsters are the only trigger, so value depends on the Watt board; Legal copies assumed to be 3
- Data gaps: no decks supplied — deck/synergy signals unavailable no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no legal copies supplied per format no searcher or Watt-support evidence supplied role hints all false and not informative
