Watthopper — Power Evaluation

Final Score: 47 ± 8 · Confidence: Medium

  • Intrinsic: 44 · Deck: 48 · Meta: provisional
  • Primary role: Utility · Secondary: Material body

Why it scores here

Watthopper is a Level 1 Light Thunder body whose only printed effect protects other face-up Watt monsters from being attacked or targeted by the opponent's card effects. It converts into no card advantage, no searches, and no boards in the evidence, so its score rests on being a cheap, consistently run Watt support piece. Its 3-copy inclusion across all 5 sampled decks and 3 archetypes shows portability, but guardrail 3 means that frequency only confirms it is a practical staple and does not raise its power.

Axis scores

Axis Score Evidence
Accessibility 50 The card is a cheap Level 1 body run at 3 copies in all 5 sampled decks, but no searcher or combo route is recorded (observed/inferred).
Combo & Conversion 20 The text only protects Watt monsters and builds nothing by itself, and there are zero recorded combo boards (verified text, observed absence).
Resource Economy 15 No draw, search, or GY refuel appears in the text, so it is a neutral body (verified).
Effect & Interaction 20 The protection stops opponent attacks and targeting on Watts but does not negate or remove anything (verified text).
Material Utility 40 A Level 1 non-Tuner Thunder body with usable Synchro/Xyz fit but no evidence of material use in boards (inferred).
Resilience & Flexibility 35 The protection depends on a face-up Watt on board and the card is weak after its effect is negated; redundancy is only supported by the 3-copy count (inferred).
Deck-Building Efficiency 80 Cheap, no garnet or lock, and 3 copies are routinely run in the sampled decks (observed).

Calculation

Weight profile: Utility / no clear role default weights (no single role dominates the text); no role blend applied. Intrinsic ≈ 44, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Cheap Level 1 body run at 3 copies in every sampled Watt and Harpie deck
  • Protection effect shields other face-up Watt monsters from attacks and targeted effects
  • Low deckbuilding cost with no garnet or self-lock

Weaknesses

  • No searcher, combo, or card-advantage route in the evidence
  • Protection only applies while another face-up Watt is on the field
  • Zero recorded combo boards, so combo conversion rests on text alone

Counters / choke points

  • Opponent board wipes or non-targeting effects bypass the protection
  • Opponent can remove the protected Watt by effects that ignore targeting

Best use

Utility support body for Watt protection and Level 1 material. Decks: Watt, Harpie. Suggested copies: 3.

Evidence & gaps

  • Verified: Effect text: opponent cannot select another face-up Watt monster as an attack target or target it with card effects; Level 1 Light Thunder Effect Monster, archetype Watt; Formats: TCG, OCG, MasterDuel
  • Observed: Run at 3 copies in 5 of 5 sampled decks; Appears in 3 archetypes (Harpie, Watt, Sự kiện N/R); Partners include Wattcobra and Wattdragonfly in 5 of 5 decks; Guide CORE section lists the card with Watt partners
  • Inferred: Role is a protective Utility body rather than a searcher or starter; Material value is generic for a Level 1 non-Tuner
  • Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
