Aqua Jet — Power Evaluation
Final Score: 42 ± 8 · Confidence: Medium
- Intrinsic: 40 · Deck: 43 · Meta: provisional
- Primary role: Utility · Secondary: Board breaker
Why it scores here
Aqua Jet is a one-for-one Spell that gives +1000 ATK to one face-up Fish, Sea Serpent, or Aqua monster. It converts an existing body into a larger attacker but builds no board, draws nothing, and does not interact with the opponent. The score comes from being cheap and live in 15 recent decks across 5 archetypes, with no combo data to lift it further. Its 1000 ATK gain earns nothing by itself; the target restriction and dependence on an existing body are what hold it back.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Spell in hand with a live target in Shark, Gunkan, and Kaiju/Harpie-adjacent lists; present in 15 of 15 recent decks at about 2 copies each, but there is no combo starter or searched data (decks evidence, observed). |
| Combo & Conversion | 30 | Text only adds 1000 ATK to one monster and does not summon, search, or build a board; no recorded boards include it (verified text, inferred conversion). |
| Resource Economy | 35 | A 1-for-1 Spell with no draw, search, or recursion; it costs a card for a temporary stat gain (verified text). |
| Effect & Interaction | 10 | No negation, removal, or disruption; it is an offensive pump only (verified text). |
| Material Utility | 5 | A Spell can never be Xyz, Synchro, Fusion, or Link material, so this axis is near zero (verified text, inferred). |
| Resilience & Flexibility | 30 | Can be negated on activation and only targets Fish, Sea Serpent, or Aqua monsters, which narrows its live spots; multi-archetype use helps somewhat (decks evidence, inferred). |
| Deck-Building Efficiency | 60 | Cheap, non-garnet, and runs 1 to 3 copies with no lock, but its dead-without-target nature limits how useful extra copies are (decks evidence, inferred). |
Calculation
Weight profile: Utility / no clear role default profile; no blend applied. Intrinsic ≈ 40, Deck ≈ 43, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap, non-garnet spell that is live in hand whenever a valid Fish, Sea Serpent, or Aqua body is out
- Appears in 15 recent decks across Shark, Gunkan, Kaiju, and Harpie lists at about 2 copies each, so it is a practical, not forgotten, pick
- Turns an existing attacker into a bigger one, which can win a battle or push damage
Weaknesses
- Needs a face-up legal target already on the field; no way to create one
- No interaction, card advantage, or board building
- Cannot be used as material, and its effect is narrowed to three type labels
Counters / choke points
- Negation or removal of the target monster in response to activation
- Opponent negating the Spell itself when it is activated
Best use
Utility. Decks: Shark, Gunkan. Suggested copies: 2.
Evidence & gaps
- Verified: Spell that targets 1 face-up Fish, Sea Serpent, or Aqua monster you control and gives it +1000 ATK; Card type is Spell Card with no material or link role
- Observed: Present in 15 of 15 recent decks, 2.07 copies average, distribution 1 to 3 copies; Five archetypes, with Shark and Gunkan at 5 decks each
- Inferred: Offensive pump whose real value depends on a legal target already being on the field; Resilience is limited by the target restriction and by the card being a negatable Spell
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no rulings or legal-format detail beyond the formats list
