Abyss-scale of the Mizuchi — Power Evaluation
Final Score: 38 ± 8 · Confidence: Medium
- Intrinsic: 39 · Deck: 38 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Utility
Why it scores here
The card's value is a narrow, one-use negation of a Spell effect activated on the opponent's side of the field, which then sends the card to the Graveyard, so it converts one card into one negated effect with no recurring value. Its Equip body only matters while a Mermail monster is on the field, which keeps accessibility at mid-range and caps combo conversion, since there are no recorded boards to show it starting or extending a combo. High deck counts and the Mermail core guide placement confirm it is a real Mermail-line tech, but the 400/400 deck sample is filtered to decks that already contain the card, so that presence says nothing about its inclusion rate and does not raise the score; the 1-copy, 30-archetype spread is a deck-fit signal, not a power signal.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Needs a Mermail monster on the field to equip and has no recorded searcher or starter route; the Mermail guide places it in the CORE section, which supports a live but conditional route (verified text, observed guide placement, inferred route). |
| Combo & Conversion | 25 | Text gives +800 ATK and a negation with no board-building effect, and there are zero combo boards, so conversion is text-only (verified text, inferred). |
| Resource Economy | 40 | Trades itself for one negated Spell effect with no draw, search, or recursion, so it is roughly even at best (verified text, inferred). |
| Effect & Interaction | 35 | Negation only covers Spell effects activated on the opponent's side of the field, a narrow scope that is not hand-trap reach (verified text, inferred). |
| Material Utility | 10 | It is an Equip Spell and not a monster, so it has no material value (verified text). |
| Resilience & Flexibility | 30 | Single-zone, single-use card that is stranded when the equipped monster leaves the field and goes to the GY after one use (verified text, inferred). |
| Deck-Building Efficiency | 45 | One copy per deck with no garnet or lock, but it occupies a Mermail-specific slot in lines that run it (observed deck copies, inferred slot cost). |
Calculation
Weight profile: 0.7 Removal / Negation + 0.3 Utility. Intrinsic ≈ 39, Deck ≈ 38, Meta = provisional. Modifiers: Archetype-locked equip target (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Negates a Spell effect activated on the opponent's side of the field
- Equip gives +800 ATK to a Mermail monster
- Single copy per deck, no garnet or lock cost
- Named in the CORE section of a Mermail guide
Weaknesses
- Requires a Mermail monster on the field to equip
- Negation scope is limited to Spell effects activated on the opponent's side of the field
- Goes to the Graveyard after one use, so no recurring value
- No combo evidence to show it converts into board or advantage
Counters / choke points
- Destroying or banishing the equipped Mermail monster strands the card
- Opponent plays that do not activate a Spell effect on their side of the field are not negated
- Opponent's Spell or Trap removal of the card on the field
Best use
Single-copy Mermail-line negation and ATK equip. Decks: Mermail, Mermail Atlantean, Atlantean. Suggested copies: 1.
Evidence & gaps
- Verified: Equip only to a Mermail monster, gaining 800 ATK; Negates a Spell effect activated on the opponent's side of the field when it resolves, then sends itself to the Graveyard; Card is a Spell Card in formats TCG, OCG, MasterDuel, DuelLinks
- Observed: Appears in all 400 sampled decks at 1 copy on average, all in main deck; Mermail and Atlantean archetypes account for most sampled decks; Mermail guide lists the card in its CORE section
- Inferred: Negation is a one-for-one trade with no recurring value; Accessibility depends on having a Mermail monster on the field
- Data gaps: No combos supplied, so combo conversion is text-only deck data shows 400 of 400 decks running the card, so the sample appears filtered to decks containing it and presence does not measure inclusion rate usage statistics lists only the Ryu-Ge archetype and gives no Mermail or Atlantean inclusion data No banlist token, so 3 copies assumed No rulings on negation timing against opponent responses
