Sea Lord's Amulet — Power Evaluation
Final Score: 43 ± 6 · Confidence: Medium
- Intrinsic: 43 · Deck: 44 · Meta: provisional
- Primary role: Floodgate/Control · Secondary: Utility
Why it scores here
Sea Lord's Amulet is a cheap continuous protection spell: it makes every WATER monster you control immune to destruction by the opponent's card effects, and it shows up in 13 recent decks (mainly Shark). It converts into a defensive overlay that can shield Xyz bodies like Bahamut Shark and Number 101, but it advances nothing on its own and self-destructs on the opponent's 3rd End Phase after activation. Because it is WATER-locked and stops only destruction (not banish, bounce, or negation) while being removable itself, its value stays modest and situational. There are no ATK/DEF stats to reward here — it is a bodiless Spell, so the score comes entirely from accessibility and passive defensive utility.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 48 | A main-deck Continuous Spell appearing in 13 recent decks across 5 archetypes (mostly Shark), but with no search route in the evidence, so it is drawn rather than tutored (observed). |
| Combo & Conversion | 15 | combo data shows 0 appearances and no starter/material/payoff role, so it builds nothing from a realistic start (observed). |
| Resource Economy | 36 | It is roughly a -1 (one card spent for a passive effect) that only returns value if it actually saves a WATER monster from destruction (inferred). |
| Effect & Interaction | 36 | Its only interaction is defensive: it blocks destruction by the opponent's card effects, with no negation, removal, or disruption of the opponent's plays (verified). |
| Material Utility | 5 | As a Continuous Spell it provides no body, level, attribute, or material value, so it converts to nothing as material (verified). |
| Resilience & Flexibility | 45 | It shields your WATER monsters across turns until it self-destructs on the opponent's 3rd End Phase, but is itself vulnerable to Spell/Trap removal and stops only destruction (verified). |
| Deck-Building Efficiency | 55 | A 1-2 copy tech with no garnet and no lock, though it is WATER-only and therefore not splashable outside WATER decks (observed). |
Calculation
Weight profile: Floodgate/Control primary (no blend). Intrinsic ≈ 43, Deck ≈ 44, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Blanket destruction protection for all WATER monsters you control, including Xyz bosses.
- Cheap to run: 1-2 copies, no garnet, no self-locking restriction.
- Confirmed real role in 13 recent decks, predominantly Shark, with observed partners like Bahamut Shark and Buzzsaw Shark.
- Lasting multi-turn effect that keeps protecting until the opponent's 3rd End Phase after activation.
Weaknesses
- Only affects WATER monsters, so it is unusable outside WATER decks.
- Protects against destruction only — not banish, bounce, negation, or battle.
- Provides no board development, no card advantage, and no disruption of the opponent.
- Self-destructs on the opponent's 3rd End Phase after activation, capping its duration.
- Itself removable by Spell/Trap removal, which removes the protection layer.
Counters / choke points
- Cosmic Cyclone / Twin Twisters / Mystical Space Typhoon (Spell/Trap removal)
- Non-destruction removal such as banishing or returning monsters to hand or Deck
- Effect negation aimed at the WATER monster before the protection resolves
- Battle-based removal, since the effect only stops destruction by card effects
Best use
Defensive protection for WATER monsters and Xyz bosses. Decks: Shark. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: WATER monsters you control cannot be destroyed by your opponent's card effects.; Card text: send this card to the Graveyard during your opponent's 3rd End Phase after activation.; It is a Continuous Spell with 0 ATK / 0 DEF and no body.
- Observed: Appears in 13 recent decks, all main deck, average 1.46 copies (range 1-2).; Archetypes: Shark (7 decks, 53.8%; another Shark id 3 decks, 23.1%), plus Sky Striker, Plunder Patroll, Gishki at 7.7% each.; Observed partners include Bahamut Shark (84.6%), Buzzsaw Shark (76.9%), Number 101: Silent Honor ARK (69.2%).; combo data: 0 appearances with no starter/material/payoff roles.
- Inferred: The WATER-only clause restricts the card to WATER decks, limiting its generic utility.; Protection is purely defensive and stops only destruction, not banish, bounce, or negation.; As a Spell it provides no material/level/attribute value.
- 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 dated metagame sample, so meta power is null
