Wattkey

Wattkey — Power Evaluation

Final Score: 27 ± 6 · Confidence: Medium

• Intrinsic: 27 · Deck: — · Meta: provisional
• Primary role: Utility · Secondary: Combo enabler

Why it scores here

Wattkey is a one-line Normal Spell that lets face-up "Watt" monsters attack directly for a turn, so its value is real but entirely conditional: it does something only once a Watt board already exists, and it builds nothing by itself. It supplies no card advantage, no search, and no interaction with the opponent, so this score comes almost entirely from the damage it can convert, not from any stat, rarity, or popularity signal. With zero deck, combo, and guide records in the supplied sample, the evaluation rests on card text alone and is explicitly provisional; the lethal-swing ceiling earns some credit, but the requirement for a pre-existing archetype board plus the one-shot nature caps the card.

Axis scores

Calculation

Weight profile: 0.7 Utility (default) + 0.3 Starter/Combo enabler. Intrinsic ≈ 27, Deck ≈ —, Meta = provisional. Modifiers: none. Final formula: Final = Intrinsic (no decks and no combos supplied; Deck = null)

Strengths

• Grants direct attacks to every face-up "Watt" monster for the turn, converting an existing board into a damage burst (verified text).
• Simple, unambiguous Normal Spell text with no cost, no lock, and no timing ambiguity (verified).
• Occupies a single deck slot and can be held for the turn it is needed, so it does not interfere with the main engine (inferred).

Weaknesses

• Completely dead without face-up "Watt" monsters; it cannot start, extend, or rebuild a board (verified text).
• Provides no card advantage or search - it is a straight -1 that adds only battle damage (verified).
• Offers no interaction with the opponent's board, hand, or Graveyard (verified).
• One-shot, Battle-Phase-only effect with no recovery or reuse (verified).
• Archetype-locked: it has no application outside a Watt build (verified).

Counters / choke points

• Negating the Spell's activation (generic Spell/Trap negation) makes it a wasted card.
• Removing the face-up "Watt" monsters before the Battle Phase blanks the effect entirely.
• Battle Phase disruption or cards that end the Battle Phase stop the direct-attack swing.
• Defensive boards or damage-prevention effects that absorb direct attacks blunt the payoff.

Best use

Finisher - direct-attack enabler to close games with an established Watt board. Decks: Watt. Suggested copies: 1.

Evidence & gaps

• Verified: Card text: face-up "Watt" monsters you control can attack your opponent directly this turn.; It is a Normal Spell Card in the "Watt" archetype, legal in TCG, OCG, and Master Duel.; The card has 0 ATK/0 DEF and no monster body, Level, Attribute, or Link value.; The supplied sample contains 0 decks, 0 combos, and 0 guides for this card, and usage_statistics is unavailable.
• Observed: Measured sample values are all zero: total_decks = 0, total_combos = 0, appearance_pct = 0, total_guides = 0.
• Inferred: Because it grants direct attacks to all face-up Watt monsters, it converts an existing Watt board into a lethal or near-lethal combat turn.; It is a dead card whenever the controller has no face-up Watt monsters, and it cannot create that board state itself.; It contributes nothing defensively - no removal, negation, or floodgate effect - so it is purely a damage-race finisher.; Its best deployment is as a low-count finisher in a Watt deck rather than a core engine piece.
• 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
