Mermail Abyssnose — Power Evaluation

Final Score: 42 ± 8 · Confidence: Medium

  • Intrinsic: 43 · Deck: 41 · Meta: provisional

Why it scores here

Mermail Abyssnose is a conditional tutor that searches Mermail monsters from the Deck when it destroys an opponent's monster in battle. While the tutoring effect is clean and the card provides solid Level 4 WATER material, the strict battle requirement severely restricts when the effect triggers, and the zero appearances in recorded combos suggest limited practical conversion in actual games. The card appears as a one-copy tech in Mermail and niche off-archetype builds, indicating it is valuable but not essential within its home archetype.

Axis scores

Axis Score Evidence
Accessibility 35 Requires on-field presence, battle with opponent's monsters, and WATER discard cost; searchable by Mermail support but battle condition creates high activation friction (verified from text).
Combo & Conversion 25 Effect promises to search and summon a Mermail when triggered, extending field presence, but zero combo appearances in evidence despite Mermail being a known archetype indicates low practical trigger rate (observed: combos_evidence.appearances=0).
Resource Economy 55 Discard 1 WATER monster to search and summon 1 Mermail from Deck is roughly even resource exchange; GY discard synergizes with Mermail's archetype strategy (inferred from text and Mermail archetype mechanics).
Effect & Interaction 5 Provides zero opponent interaction—no negation, removal, or disruption of opponent plays (verified from card text).
Material Utility 60 Clean Level 4 WATER Fish body functions as material for Synchro, Xyz, and other summoning methods even when effect is negated or blocked (verified from text and attributes).
Resilience & Flexibility 30 Single-zone, one-time-per-turn effect vulnerable to blocking via walling effects or enemy stat reduction; no built-in recovery or multi-turn presence (inferred from text and battle dependency).
Deck-Building Efficiency 45 Archetype-specific tutor appearing in 1 copy across all observed decks; requires Mermail support infrastructure to maximize value; limited to 2 distinct archetypes in evidence (observed: decks_evidence.archetypes=2, copies_per_deck.distribution={1:5}).

Calculation

Weight profile: 0.7 Extender + 0.3 Searcher/Tutor. Intrinsic ≈ 43, Deck ≈ 41, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Tutors any Mermail from Deck, providing flexible archetype-specific search
  • Clean Level 4 WATER material even when effect is negated
  • Synergizes with Mermail's Graveyard-focused strategy via WATER discard cost
  • Modular within Mermail family—no lock-in, works with all Mermail support

Weaknesses

  • Battle requirement severely limits activation rate; card is dead without attacking successfully
  • Appears only as 1-of in all observed decks, indicating optional/conditional inclusion
  • No opponent interaction or defensive utility
  • Zero recorded combo appearances despite Mermail being an established archetype suggests low practical synergy with combo lines
  • Archetype-specific; not splashable outside Mermail

Counters / choke points

  • Walling effects block battle trigger entirely
  • Stat reduction or negation effects (Ash Blossom, Veiler) disable tutor
  • Opponent's destruction of Abyssnose before attack prevents activation

Best use

Conditional extender and archetype tutor in battle-focused Mermail lines. Decks: Mermail. Suggested copies: 1.

Evidence & gaps

  • Verified: Card text requires destroying opponent's monster in battle and discarding 1 WATER to search Mermail from Deck; Level 4 WATER Fish type confirmed from card attributes; Appears in 5 decks, all running 1 copy; 60% Mermail, 40% Mayakashi Shiranui (from decks_evidence); All top partners are Mermail archetypes except Monster Reborn and Surface (from top_partners)
  • Observed: 100% of 5 observed decks run exactly 1 copy in main deck; 0 side deck appearances (from copies_per_deck); Zero appearances in any recorded combo boards despite being in Mermail decks (from combos_evidence.appearances=0); Not ranked as a top card across any format (from top_card_context.is_top_card=false)
  • Inferred: Battle requirement creates high activation friction in non-aggressive Mermail lines; WATER discard cost aligns with Mermail archetype's Graveyard strategy; Tutors any Mermail from Deck, providing flexible targeting within archetype; Functions as Level 4 WATER material for Synchro, Xyz, and other summons even when effect is blocked; Archetype-specific role; low distinct_archetypes (2) and all-Mermail top partners indicate limited splashability
  • Data gaps: No combos supplied — combo conversion is text-only inference; zero combo appearances is a strong null signal No guides supplied — archetype role and optimal usage context unavailable No banlist token — assumed 3 copies (unlimited); actual status unknown No usage statistics (StatisticsCard) — archetype inclusion percentage inferred from 5-deck sample only Small deck sample (5 total) limits confidence in archetype-wide conclusions; may not reflect full metagame
