Mermail Abysslung — Power Evaluation

Final Score: 50 ± 6 · Confidence: Medium

  • Intrinsic: 52 · Deck: 50 · Meta: provisional
  • Primary role: Utility · Secondary: Material body, Floodgate/Control

Why it scores here

Mermail Abysslung is a soft-protection piece with modest defensive utility and clean deckbuilding that appeals to WATER strategies. It protects allied WATER monsters from opponent attacks while providing a marginal 300-ATK buff, but neither effect generates card advantage or creates board presence independently. Its primary value lies as a Level 4 WATER body for material synergy and as a flexible deck slot in themed homes; without combo synergy or searchable recursion, it performs as a tech filler rather than a core engine piece.

Axis scores

Axis Score Evidence
Accessibility 42 Level 4 WATER bodies are searchable via generic and themed support, but this card runs at exactly 1 copy in all 7 sample decks, indicating a flex/tech slot rather than a critical piece (observed).
Combo & Conversion 32 No combo evidence supplied; the card provides only static board effects without card generation, recursion, or combo amplification on its own (inferred).
Resource Economy 35 Text contains no card draw, tutoring, or recursion; the attack prevention provides soft tempo gain but no card advantage, and the 300-ATK buff is marginal outside dedicated Mermail builds (inferred).
Effect & Interaction 28 Attack prevention is soft interaction that applies only to opponent attacks on WATER targets—opponent can bypass it by attacking this card or using non-attack strategies (inferred).
Material Utility 68 Level 4 WATER Fish is clean generic material for synchro and xyz, with no self-lock, and gains archetype synergy in Mermail and WATER-focused homes (verified).
Resilience & Flexibility 38 Confined to the field; dies to a single removal spell, and the effect provides no protection to itself or recover mechanism if destroyed (inferred).
Deck-Building Efficiency 78 Consistently runs at 1 copy across 4 distinct archetypes (Mermail, Kashtira, Mayakashi Shiranui, Umi Control) with no garnish or lock—a clean flex slot splashable in WATER strategies (observed).

Calculation

Weight profile: 0.7 Utility + 0.3 Material body. Intrinsic ≈ 52, Deck ≈ 50, Meta = provisional. Modifiers: Limited deck sample (-1). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Clean, splashable Level 4 WATER body with no self-locking effects
  • Consistent inclusion across diverse archetypes (Mermail, Kashtira, Umi Control) shows real utility
  • Protects allied WATER monsters while also providing marginal ATK boost in themed homes
  • No garnish or brick risk; 1-copy slot integrates smoothly

Weaknesses

  • No card advantage generation; attack prevention is soft interaction that opponents can easily bypass
  • Dies to a single disruption with no recovery; confined to field only
  • Dependent on WATER synergy—narrow archetype appeal outside dedicated themes
  • Does not function as a combo enabler or board accelerant; more of a flex tech piece
  • Marginal stats (1200 ATK, 1800 DEF) offer limited combat value

Counters / choke points

  • Destruction (MST, Raigeki, Lightning Storm) removes protection and body value
  • Negation (Ash Blossom) prevents activation if treated as an effect
  • Non-attack strategies (burn, combo damage) bypass attack prevention entirely
  • Banishment effects that bypass the graveyard

Best use

Board protection piece and material provider. Decks: Mermail Atlantean (primary home—28.6% inclusion with searchable Level 4 support), Umi Control (thematic fit with WATER-focused control strategy), Kashtira (tech pick—WATER splash for board diversity). Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: attack prevention on opponent's attacks + 300 ATK buff to WATER monsters; Type and attributes: Level 4 WATER Fish (standard synchro/xyz material); Appears in 7 decks across 4 distinct archetypes with consistent 1-copy inclusion
  • Observed: 28.6% inclusion rate in Mermail Atlantean (primary home); 28.6% inclusion rate in Kashtira (tech pick); Paired with generic board wipes and staples, suggesting flexible deck slot role; View count 2,934 indicates moderate page popularity but no Top-Card ranking
  • Inferred: Attack prevention is soft interaction—opponent can attack this card or use non-attack strategy; 300-ATK buff is marginal outside Mermail themes but relevant for their boards; No card advantage engines, recursion, or combo amplification in text; Splashable in WATER strategies due to archetype-agnostic material utility; Does not function as a core combo piece or enabler; primarily a flex tech slot
  • Data gaps: No combos supplied—combo conversion assessment is text-only inference No guides supplied—no human context on deck building or strategy No usage statistics (StatisticsCard available=false)—archetype inclusion % inferred from 7-deck sample only No banlist token—assumed unlimited (3 copies) No top_card ranking—confirms this is not a metagame staple Small deck sample (7 total) limits confidence in deck_synergy and role verification across archetypes
