2 Level 2 monsters While this card has an Xyz Material attached that was originally WATER, it cannot be destroyed by battle. Once per turn, during either player's turn: You can detach 1 Xyz Material from this card, then target 1 Rank 4 or lower Xyz Monster you control; its ATK and DEF each become double its original ATK and DEF until the end of this turn.
Cat Shark — Power Evaluation
Final Score: 46 ± 8 · Confidence: Medium
- Intrinsic: 46 · Deck: 46 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Cat Shark is a Rank 2 Xyz whose real value is a conditional ATK doubling of a Rank 4 or lower Xyz once per turn, paid by detaching a material, plus battle protection only while it holds a WATER material. Its 500 ATK and 500 DEF earn nothing. It has no effect-based protection, no negation or removal, and no recorded combo evidence, so the score sits near the middle of the range. The breadth of its deck sample (55 archetypes) supports portability, but that breadth is conditional on the card already being in the deck, so it does not raise the score beyond the rubric's cap.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Reachable through Xyz summons from Level 2 monsters, which the sampled Spright-family decks supply (inferred; no combo starter or searched data, so only partly confirmed). |
| Combo & Conversion | 40 | The ATK doubling can turn an existing Rank 4 or lower Xyz into a lethal attacker, but no recorded boards confirm this (verified text, inferred impact). |
| Resource Economy | 30 | Its only effect costs a material and returns no card or advantage (verified text). |
| Effect & Interaction | 10 | It has no negation, removal, or hand-trap effect in its text (verified text). |
| Material Utility | 30 | As an Xyz it is not a generic material body and its effect consumes its own materials, so it converts poorly as material (verified text, inferred). |
| Resilience & Flexibility | 35 | Battle protection depends on a WATER material remaining attached, and nothing protects it from effects (verified text). |
| Deck-Building Efficiency | 60 | One Extra Deck slot at 1 copy in 389 of 400 sampled decks, with no garnet or lock restriction (observed; the sample is conditional on the card being present). |
Calculation
Weight profile: Utility / no clear role default (no dominant combo role). Intrinsic ≈ 46, Deck ≈ 46, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck (decks present, combos absent, meta unknown)
Strengths
- Two Level 2 monsters summon it, so it is an accessible Rank 2 Xyz
- Once-per-turn ATK and DEF doubling of a Rank 4 or lower Xyz can produce a lethal attack
- Battle protection while a WATER material is attached
- Appears in 400 sampled decks across 55 archetypes
Weaknesses
- 500 ATK/DEF body with no board presence on its own
- Its effect costs one material and returns no advantage
- No protection from effects, and no negation or removal
- No recorded combo boards to confirm its conversion value
Counters / choke points
- Negating its effect, which stops the ATK doubling (inferred from text)
- Removing its WATER material, which ends battle protection (inferred from text)
Best use
Utility Rank 2 Xyz that supplies a conditional ATK-doubling finisher. Decks: Spright-family Xyz builds, Nimble and Frog Xyz lists in the sample. Suggested copies: 1.
Evidence & gaps
- Verified: Text: two Level 2 monsters as material; Text: once-per-turn detach to double a Rank 4 or lower Xyz's ATK and DEF; Text: battle protection while a WATER material is attached; Sample: 400 decks, 55 archetypes, 1 copy in 389 decks
- Observed: 76.8% of decks are gameplay type 7; Gigantic Spright co-occurs in 85.8% of sampled decks; Usage statistics: 60% inclusion in Subterror and Nimble (gameplay 4)
- Inferred: Accessible through Level 2 monsters from Spright-family decks; ATK doubling acts as a finisher when a Rank 4 or lower Xyz is present; Role is Utility, with a secondary Material body reading
- Data gaps: No combos supplied, so combo conversion is text-only inference No banlist or legal_copies token; assumed 3 copies Deck sample is conditional on the card being present, so decks_running_main 400/400 and partner percentages are not an inclusion rate Partner percentages are inflated by shared archetype membership Usage statistics cover only two archetypes No rulings or guide detail on the ATK-doubling targeting in practice
