Watthydra — Power Evaluation
Final Score: 53 ± 8 · Confidence: Medium
- Intrinsic: 52 · Deck: 54 · Meta: provisional
- Primary role: Utility · Secondary: Boss/End-board, Extender
Why it scores here
Watthydra's score comes from its direct-attack trigger, which converts one unblocked hit into a card added from the Deck two Standby Phases later, so its value depends on reaching battle damage. Its 1500 ATK and Level 7 body earn nothing on their own. The Watt-deck evidence (67 decks, 98.5% co-appearance with Watt Tuners) confirms it is reliably accessible in its home, but the absence of combo data keeps the conversion axis moderate.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Synchro-summoned with a Watt Tuner plus a Thunder non-Tuner, and it co-appears with Wattcobra, Wattuna and Wattkyuki in 98.5% of its decks (observed, inferred from text). |
| Combo & Conversion | 55 | Its text turns a successful direct attack into a delayed card, but no combo boards were supplied to confirm how often that happens (inferred). |
| Resource Economy | 65 | One extra card per successful direct attack via a Deck-to-hand add, with no cost shown in the text (verified). |
| Effect & Interaction | 10 | It has no negation, removal or hand-trap reach; the only interaction is the card's own trigger (verified). |
| Material Utility | 25 | As a Level 7 Synchro it is a poor material body, and no material-usage data was supplied (inferred). |
| Resilience & Flexibility | 45 | The effect needs a direct attack to resolve and has no protection against a single interruption, so it is fragile (inferred). |
| Deck-Building Efficiency | 60 | Typically 1 copy per deck, with a cheap home inside the Watt shell and no garnet or lock restriction (observed). |
Calculation
Weight profile: Utility / no clear role default (no single role dominates; Boss/End-board is only a secondary read). Intrinsic ≈ 52, Deck ≈ 54, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Reliable direct-attack card advantage inside the Watt shell
- Cheap to run at 1 copy, with 98.5% partner overlap with core Watt Tuners
- Sustained inclusion across Watt gameplay types
Weaknesses
- Requires a direct attack, so it is dead against a board of blockers
- Delayed (2nd Standby) payoff is slow
- Almost no interaction or material value
Counters / choke points
- Monster-effect negation or hand traps that stop the Synchro summon or the attack (inferred from text)
- Blockers that prevent battle damage, which shuts off the trigger (inferred from text)
Best use
Synchro finisher that adds a card from the Deck after a direct attack. Decks: Watt. Suggested copies: 1.
Evidence & gaps
- Verified: Text: direct-attack trigger adds a Deck card on the 2nd Standby Phase; Level 7 Synchro requiring a Watt Tuner and a Thunder non-Tuner; Attribute LIGHT, Thunder race, Watt archetype
- Observed: 67 of 67 recent decks run it, with 1.25 copies on average; 53.7% of decks are Watt archetype, 9% Kaiju, 7.5% Melodious; usage statistics: 100% inclusion in gameplay 4 and 66.7% in gameplay 7 (1 copy typical)
- Inferred: Accessibility depends on a live Watt Tuner in the opening hand; Direct attack is needed to trigger the effect, so blockers stop it
- Data gaps: no combos supplied, so combo conversion and power index are text-only inference no banlist token, assumed 3 copies (unlimited) no rulings for the delayed 2nd Standby add timing Tuner status of Wattcobra, Wattuna and Wattkyuki is not in the evidence
