Mermail Abyssmegalo — Power Evaluation
Final Score: 70 ± 6 · Confidence: Medium
- Intrinsic: 67 · Deck: 69 · Meta: provisional
- Primary role: Extender · Secondary: Searcher/Tutor
Why it scores here
Mermail Abyssmegalo is a core extender in WATER-focused decks that consistently self-summons via discard cost while searching for spell/trap support, but its power is anchored in deck synergy rather than intrinsic stats. The card's 2400 ATK does not earn points—it is the self-summon efficiency, searchable spell/trap access, and the role it plays within established Mermail and Atlantean shells that drive the evaluation. Without combo evidence to verify how reliably it builds full boards, the score reflects deck-level inclusion and guide confirmation alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 75 | Appears in all 400 sampled decks with average 1.21 copies; supported by Atlantean Dragoons and other WATER searchers as discard outlets (Verified). |
| Combo & Conversion | 68 | Text describes search and attack doubling, but no combo boards supplied to verify synergy depth; score reflects text-only inference (Inferred). |
| Resource Economy | 62 | Discard cost of 2 WATER monsters is offset by the spell/trap search; roughly even trade preserving Normal Summon (Verified). |
| Effect & Interaction | 35 | No direct negation, removal, or hand-trap functionality; disruption is indirect via searched support cards (Verified). |
| Material Utility | 68 | Level 7 WATER attribute fits Xyz and Synchro lines; serviceable body for generic WATER synergy (Observed from top-partner co-deck rates). |
| Resilience & Flexibility | 55 | Self-summon provides summon resilience, but conditional second-attack effect and lack of protection reduce flexibility; single on-summon effect limits follow-up (Inferred). |
| Deck-Building Efficiency | 76 | Average 1.21 copies with 97.2% co-deck rate for Atlantean Dragoons; archetype-specific but very clean within WATER decks (Verified). |
Calculation
Weight profile: 0.7 Extender + 0.3 Searcher/Tutor. Intrinsic ≈ 67, Deck ≈ 69, Meta = provisional. Modifiers: Archetype Synergy Bonus (2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Efficient self-summon mechanism preserves Normal Summon and enables combo starts
- Dual effect (spell/trap search plus conditional double attack) provides flexibility within established decks
- Universal inclusion across 23 distinct archetypes indicates robust portability
- Clean Level 7 WATER specs for Xyz and Synchro material compatibility
- Searchable by Atlantean Dragoons and other core WATER tutors
Weaknesses
- Discard cost of 2 WATER monsters requires dedicated deck construction
- No intrinsic disruption or protection; vulnerable to hand traps once on board
- Second attack effect conditional on available WATER tribute; limits effectiveness
- Lacks combo evidence to confirm actual board-building ceiling
- Dependent on spell/trap search quality for meaningful value
Counters / choke points
- Ash Blossom & Joyous Spring (negates search effect)
- Called by the Grave (disables on-summon effects)
- Negate effects during summon or search resolution
Best use
Extender and spell/trap searcher. Decks: Mermail, Atlantean, Mermail Atlantean, Deep Sea, Icejade.
Evidence & gaps
- Verified: Card text: self-summon via 2 WATER discard, spell/trap search on summon, conditional second attack via WATER tribute; 100% inclusion in all 400 sampled decks (400/400 main); Average 1.21 copies per deck; 335 decks run 1 copy, 45 run 2 copies, 20 run 3 copies; Top partners are core Mermail/Atlantean synergy (Dragoons 97.2%, Abysspike 96%, Heavy Infantry 95.2%); Featured in 3 guides as core/staple in Mermail, Atlantean, and Icejade archetypes; Appears in 23 distinct archetypes (strong portability indicator)
- Observed: Mermail (28%) and Atlantean (28.5%) are dominant homes, with significant secondary presence in Mermail Atlantean (10.8%); Gameplay types: 71.2% Type-7 decks (standard formats), 17.2% Type-6, 11.5% Type-4; Partner synergy: all top 15 partners are WATER monsters (mostly Mermail/Atlantean searchers or Synchro enablers); Consistent inclusion across time period 2024-12 to 2026-09 with no declining trend
- Inferred: Self-summon mechanism enables flexible combo starts (specific lines unconfirmed without combo data); Spell/trap search provides deck consistency benefit; effectiveness depends on Abyss- support card quality; Level 7 WATER body fits Xyz/Synchro material roles in WATER-focused decks; Archetype diversity (23 homes) suggests good splashability within WATER-based strategies; No direct disruption text; interaction is mediated by spell/trap targets of the search
- Data gaps: No combos supplied — cannot verify actual board-building depth, power index, or role distribution (starter vs material vs payoff) No usage statistics (StatisticsCard) — archetype inclusion percentages estimated from 400-deck sample only, not from larger historical dataset No banlist information — assumed unlimited 3 copies No top-card ranking data — competitive meta impact unknown Spell/trap target pool (Abyss- cards) not detailed in evidence; search value depends on external support
