Mermail Abyssteus — Power Evaluation
Final Score: 68 ± 6 · Confidence: Medium
- Intrinsic: 67 · Deck: 68 · Meta: provisional
- Primary role: Extender · Secondary: Searcher/Tutor, Material body
Why it scores here
This card is a core Mermail extender that self-summons from hand via a trivial discard cost, then tutors a follow-up Mermail to chain effects. The self-summon + search provides solid resource economy and fits seamlessly into the archetype's WATER-discard engine, confirmed by near-universal inclusion (100% in pure Mermail/Atlantean decks). However, without recorded combo data, the ceiling of the chains it builds cannot be verified; it scores as a strong enabler rather than a dominant force, trading off resilience against negates and limited multi-turn flexibility.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 85 | The card is naturally live in hand and requires only a trivial discard cost within the WATER-heavy Mermail archetype; 2.54 copies average and 100% inclusion in pure Mermail/Atlantean decks confirm near-free accessibility (verified). |
| Combo & Conversion | 65 | The text shows a clean self-summon + search chain enabling follow-up plays, but no combo examples or end-board data prevent verification of final board scale; the HOPT clause limits repeated chains per turn (inferred). |
| Resource Economy | 75 | The card trades one discard for one field presence plus one tutor, netting +1 advantage while enabling synergy with other Mermail discard effects like Abysspike (verified by card text and 100% co-occurrence observed). |
| Effect & Interaction | 30 | The card provides no direct negation, removal, or disruption to the opponent's board; it enables teammate synergy via discard triggers but does not interact with opponent plays (inferred). |
| Material Utility | 75 | The 7-level WATER Aqua body is clean for Rank 7 Xyz summons and Synchro chains, remaining useful if effect is negated, as evidenced by 99.5% co-occurrence with Mermail Abyssgaios (observed). |
| Resilience & Flexibility | 50 | The card is vulnerable to hand traps stopping the search and negates on the self-summon, but once on field it survives as Xyz or Synchro fodder; no built-in protection limits multi-turn play and the HOPT caps recurrence to once per turn (inferred). |
| Deck-Building Efficiency | 80 | The card runs efficiently in Mermail/Atlantean (self-summons from hand with trivial cost, 2.54 copies average, 67% of decks run 3 copies) with no reported brick or garnet issues (observed). |
Calculation
Weight profile: Primary role: Extender (A=0.18, C=0.22, R=0.14, E=0.08, M=0.14, F=0.14, D=0.10). Intrinsic ≈ 67, Deck ≈ 68, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Core enabler in Mermail/Atlantean archetype with 100% inclusion in pure builds
- Clean resource economy: converts one discard into field presence plus tutor (+1 advantage)
- Self-summon from hand is nearly always live within the archetype
- WATER Aqua body serves as useful Xyz rank-7 or Synchro material
- Runs efficiently at 2-3 copies with no brick or garnet potential
Weaknesses
- No direct board interaction (no negation, removal, or disruption effects)
- Vulnerable to hand traps that interrupt the search effect
- Once-per-turn limitation restricts recurrence of tutoring
- Moderate resilience against negates on the self-summon activation
- Primarily tied to Mermail archetype; limited portability to non-WATER strategies
Counters / choke points
- Ash Blossom & Joyous Spring (stops the search)
- Herald of Oath (negates the self-summon)
- Declared disruptions preventing discard cost payment
- Board wipes offering no protection to the summoned body
Best use
Extender / Combo Enabler. Decks: Mermail, Atlantean, Mermail Atlantean, Deep Sea. Suggested copies: 3.
Evidence & gaps
- Verified: Card is 7-level WATER Aqua Effect Monster (from card properties); Card self-summons from hand by discarding 1 other WATER monster (from description); Card tutors 1 Level 4 or lower Mermail from deck when summoned this way (from description); Card has hard once-per-turn clause on the effect (from description); Card runs 2.54 copies average, max 3 (67% of decks run 3x); Card appears in 400/400 decks (100% of sample); 100% co-occurrence with Mermail Abysspike
- Observed: 100% inclusion in pure Mermail decks (105 decks in sample); 100% inclusion in pure Atlantean decks (105 decks in sample); 92.86% inclusion in Mermail Atlantean decks (57 decks in sample); 60% inclusion in Deep Sea decks (36 decks in sample); Appears in 18 distinct archetypes across 400 decks; 99.5% co-occurrence with Mermail Abyssgaios (Rank 7 Xyz)
- Inferred: Primary role is Extender (self-summon + search = combo chain enabler); Card converts discard cost into field value plus hand value (resource economy); Discard effect synergizes with other Mermail/Atlantean discard-triggered effects; 7-level Aqua body is useful for Rank 7 Xyz and Synchro summons (material utility); Card is resilient as field body after summoning but vulnerable to negates on summon/search
- Data gaps: No combos supplied—combo conversion inferred from text and deck inclusion, not verified from recorded boards No banlist token—assumed 3 copies legal in all formats No Top Card ranking data—cannot assess meta-defining status No OCG-specific deck data—sample may be TCG-heavy No DuelLinks-specific combo data—format representation unclear
