Why it scores here
Sea Koala earns its value almost entirely as a searchable Level 2 EARTH Beast body, not as a threat: its 100 ATK and its once-per-turn ATK-to-0 effect are both marginal. Deck evidence shows it riding Rescue Cat (92.3% co-deck) and Melffy shells, where it is a clean material piece rather than a card that does anything on its own. Its temporary, activation-gated ATK reduction is soft battle-based removal that requires an established Beast board, so it contributes little interaction or card economy. Because there is no combo data, its combo and conversion scores are text-only inferences and stay modest.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | It is reachable via Rescue Cat (co-deck 92.3%), Melffy Hide-and-Seek (84.6%) and Ayers Rock Sunrise (76.9%), though it still needs one of those specific enablers rather than being live on its own (observed). |
| Combo & Conversion | 36 | With 100 ATK and no combo entries it builds nothing alone; the 0 combo appearances mean any conversion to a board is a text-only inference from being a Level 2 Beast (inferred). |
| Resource Economy | 30 | It generates no card advantage, offers no search or GY refuel, and typically leaves the field as a material, so it is roughly a neutral-to-negative investment (verified). |
| Effect & Interaction | 32 | The effect only sets one opponent monster's ATK to 0 until the end of the turn and requires controlling another Beast-Type, making it situational battle-based softening rather than hard removal (verified). |
| Material Utility | 68 | As a Level 2 EARTH Beast it is clean generic Xyz/Synchro fodder and a legal Rescue Cat target, converting even when its effect is blanked (verified). |
| Resilience & Flexibility | 34 | A 100/1600 body with no protection and a Beast-only activation condition means any interaction removes it and it is dead outside Beast decks (inferred). |
| Deck-Building Efficiency | 40 | It is cheap to slot (avg 1.23 copies, mostly 1-of) but functions as a near-garnet you rarely want to hard-draw, capping its efficiency (observed). |
Calculation
Weight profile: 0.7 Material body + 0.3 Utility/Removal. Intrinsic ≈ 52, Deck ≈ 51, Meta = provisional. Modifiers: Garnet risk (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Level 2 EARTH Beast is clean generic Xyz/Synchro material and a legal Rescue Cat target
- Reachable through multiple Beast engines (Rescue Cat, Melffy Hide-and-Seek, Ayers Rock Sunrise)
- Cheap slot cost: appears at an average of 1.23 copies, mostly as a 1-of
Weaknesses
- 100 ATK / 1600 DEF body is irrelevant in combat and dies to any interaction
- Effect requires controlling another Beast-Type monster to activate and resolve
- ATK-to-0 lasts only until the end of the turn and destroys nothing
- Does nothing on its own without a Beast engine to summon or search it
Counters / choke points
- Any removal or negation on the Beast board blanks the ATK-to-0 effect
- Ash Blossom & Joyous Spring or similar stops the Rescue Cat route that summons it
- Droll & Lock Bird / hand-trap chains cut the search lines that fetch it
- Decks not built around Beast-Type monsters cannot use it at all
Best use
Searchable Level 2 Beast material / Rescue Cat target. Decks: Melffy, Scareclaw, Visas Starfrost Beast shells, Beast toolbox. Suggested copies: 1.
Evidence & gaps
- Verified: Sea Koala is a Level 2 EARTH Beast-Type Effect Monster with 100 ATK and 1600 DEF.; Its effect is once per turn, targets one opponent monster, sets its ATK to 0 until the end of the turn, and requires controlling another Beast-Type monster to activate and resolve.
- Observed: 13 sampled decks run Sea Koala, spread over 8 archetypes, mostly in Melffy/Scareclaw/Visas Starfrost Beast shells.; Rescue Cat co-occurs in 92.3% of those decks, Melffy Hide-and-Seek in 84.6%, and Ayers Rock Sunrise in 76.9%.; Average copies per deck is 1.23 (10 decks run 1, 3 decks run 2).
- Inferred: Sea Koala is used as a searchable Level 2 Beast material for Beast/Rank 2 combos rather than as a standalone threat.; The ATK-to-0 effect functions as soft, temporary battle support that requires an already-established Beast board.; Its value collapses in any deck that cannot field Beast-Type monsters or reach it via Rescue Cat.
- Data gaps: 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 no metagame sample, so meta_power is null and the final score is provisional
