Elemental HERO Mariner — Power Evaluation
Final Score: 38 ± 6 · Confidence: Medium
- Intrinsic: 37 · Deck: 38 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Elemental HERO Mariner is a Fusion-only 1400-ATK body whose only extra text is a conditional direct-attack clause while you control a face-down Spell/Trap, so it converts little on its own. Its 1400 ATK and the 170-deck presence earn nothing beyond accessibility and cheap single-copy deck cost, since frequency is not power here. The score is held down by the Fusion-material requirement, the 2-for-1 cost of the summon, and the absence of any combo, search or interaction evidence.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Fusion Summon only and needs two named HERO Fusion materials; it is live in 170 decks, but there are no searcher or starter routes in the evidence (observed). |
| Combo & Conversion | 25 | Text shows only a 1400-ATK body plus a conditional direct attack, and combo data has 0 appearances, so conversion is text-only inference (inferred). |
| Resource Economy | 25 | Two materials become one body with no draw, search or recursion in the text, so net card advantage is about -1 (verified). |
| Effect & Interaction | 5 | The card has no negation, removal or hand-trap effect (verified). |
| Material Utility | 20 | No evidence it is used as material for other cards, and the Fusion-only restriction limits its material role (inferred). |
| Resilience & Flexibility | 30 | Dependent on Extra Deck summon and two field materials, with no multi-zone or multi-turn redundancy shown (inferred). |
| Deck-Building Efficiency | 60 | Single copy in 169 of 170 decks, no garnet or lock text in the evidence, and a Fusion-only restriction that costs Extra Deck space (observed). |
Calculation
Weight profile: 0.7 Utility + 0.3 Material body (blended). Intrinsic ≈ 37, Deck ≈ 38, Meta = provisional. Modifiers: Self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in 170 recent decks across 31 archetypes, so it is practical and not a forgotten pick
- Single copy per deck with no garnet or lock text, so it is cheap to run
- Direct-attack clause gives an alternate finishing route when a face-down Spell/Trap is present
Weaknesses
- Fusion-only summon with two named HERO materials, so it needs setup
- Two cards consumed for one body, a net -1 card advantage
- No recorded combo, search or interaction evidence
- Direct attack is conditional on having a face-down Spell/Trap
Counters / choke points
- No counter evidence in the pack; generic Extra Deck hand and field disruption would stop the summon (inferred)
Best use
Fusion body and direct-attack finisher. Decks: P.U.N.K., Red-Eyes, Blue-Eyes, Heroic, Kashtira. Suggested copies: 1.
Evidence & gaps
- Verified: Must be Fusion Summoned and cannot be Special Summoned by other ways; Direct attack while a face-down card is in your Spell & Trap Card Zones; Ran in 170 decks, 169 with one copy
- Observed: Present in 31 archetypes, led by P.U.N.K. (32.4%); Gameplay types 4 (53.5%) and 7 (41.2%)
- Inferred: Fusion-only restriction limits material and resilience roles; Generic Extra Deck disruption would stop the summon
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only
