Double Shark — Power Evaluation
Final Score: 51 ± 10 · Confidence: Medium
- Intrinsic: 51 · Deck: 50 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Double Shark is a 1200-ATK Level 4 WATER Fish whose only text is a Normal Summon Level-reduction for Level 4 Fish and a second attack. It reliably gives a clean Level 4 WATER body that converts as material even when its effect is negated, and it is cheap to run at 3 copies with no garnet cost. The evidence shows no card advantage, searches, interaction, or recorded combo role, so the score stays in the middle-low range; its 1200 ATK and second-attack text earn no points by themselves.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Appears in 4 of 4 sampled decks at 3 copies each across 4 archetypes, but no searcher or starter route is evidenced (observed; no combo data). |
| Combo & Conversion | 30 | No combo boards were recorded and the text describes no field-building beyond a body, so conversion is text-only inference (inferred). |
| Resource Economy | 40 | No draw, search, or GY refuel in the text; it is roughly one card for one body (verified from text). |
| Effect & Interaction | 10 | No negation, removal, or hand-trap effect in the text; the Level-reduction is not disruption (verified from text). |
| Material Utility | 60 | Level 4 WATER Fish is a clean generic material and the body stays a Level 4 Fish even if the effect is negated (inferred from text). |
| Resilience & Flexibility | 45 | Four archetypes and 3 copies per deck give some redundancy, but a single body with no protection is easy to lose (observed deck spread; inferred fragility). |
| Deck-Building Efficiency | 70 | 3 copies, no garnet or self-lock in the text, and a generic Level 4 body make it cheap to run (verified from text and deck data). |
Calculation
Weight profile: 0.7 Utility (default) + 0.3 Material body blend. Intrinsic ≈ 51, Deck ≈ 50, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean Level 4 WATER Fish body that remains usable as material when its effect is negated
- Plays in 4 of 4 sampled decks across 4 archetypes at 3 copies each
- Cheap to run with no garnet or self-lock
Weaknesses
- No card advantage, search, or recursion in the text
- No negation or removal, so it does not interact with the opponent
- Level-reduction effect is narrow (Level 4 Fish only) and situational
- Combo evidence is absent, so its conversion value is unproven
Counters / choke points
- Standard negates and card-based removal would end the body; the text gives it no protection
Best use
Level 4 WATER material body and a second-attack body in Fish-based shells. Decks: Shark, Tachyon, Ryzeal, Deep Sea. Suggested copies: 3.
Evidence & gaps
- Verified: Text: Normal Summon Level-reduction for Level 4 Fish; second attack in Battle Phase; Level 4 WATER Fish, 1200 ATK, 4 of 4 sampled decks at 3 copies
- Observed: Appears in 4 of 4 sampled decks across 4 archetypes; Co-occurs with Surfacing Big Jaws, Drake Shark, Seventh Ascension in 4 of 4 decks
- Inferred: Body stays a Level 4 material when the effect is negated; Narrow Level-reduction has situational value only
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only deck sample is only 4 decks — accessibility and resilience confidence is thin no banlist token — assumed 3 copies (unlimited)
