Number 17: Leviathan Dragon — Power Evaluation
Final Score: 56 ± 5 · Confidence: Medium
- Intrinsic: 58 · Deck: 55 · Meta: provisional
- Primary role: Material body · Secondary: Utility
Why it scores here
Leviathan Dragon scores as a generic, highly splashable Rank 3 Xyz that appears in all 400 sampled decks across 85 distinct archetypes, demonstrating exceptional accessibility and deckbuilding efficiency. However, the card generates no card advantage, builds no combo lines (zero recorded appearances in combo boards), and contributes zero disruption or opponent interaction. It functions as a stepping-stone material body: a 2000 ATK filler Xyz whose ability to detach materials for +500 ATK per turn is merely acceptable when the deck has spare Level 3 monsters, not a power amplifier.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 75 | Summoned from any 2 Level 3 monsters with universal availability; appears in 100% of 400 sampled decks across 85 distinct archetypes (verified: deck data shows 400/400 decks, 85 distinct archetypes). |
| Combo & Conversion | 15 | Card text alone generates no multi-step advantage or board-building; confirmed by zero recorded combo board appearances (verified: combo data shows 0 appearances and 0 example boards). |
| Resource Economy | 25 | Requires 2 monsters to summon (net −1 card) with zero refuel or card-draw effect; detach-for-ATK is a pure stat trade (−1 material for +500 ATK only) (verified: card description contains no advantage clause or draw engine). |
| Effect & Interaction | 5 | Pure offensive self-buff with zero disruption, negation, removal, or opponent interaction; generates no opposing plays countered (verified: card description contains no opponent-facing effects). |
| Material Utility | 60 | 2000 ATK generic WATER Dragon body is usable as Xyz material even when effect is negated; Rank 3 value converts into higher Xyz or Synchro plays (observed: appears as filler in 85 archetypes' extra decks, top deck partners are generic control staples, not synergy cards). |
| Resilience & Flexibility | 35 | No protection or evasion from removal; locked from direct attack when materials are depleted; limited multi-turn utility (inferred: card text restriction removes direct-attack option at 0 materials, no inherent resilience clauses or protection). |
| Deck-Building Efficiency | 85 | Zero self-lock, zero garnet cost, splashable into any deck producing 2 Level 3 monsters; appears as filler Xyz in 85 archetypes without restriction (observed: deck data shows 85 distinct archetypes, 1.12 avg copies, no archetype-specific clustering). |
Calculation
Weight profile: Primary: Material body. Intrinsic ≈ 58, Deck ≈ 55, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Universally splashable: summoned from any 2 Level 3 monsters with no archetype lock or requirement.
- Zero deckbuilding cost: no self-restriction, no garnet liability, redundant copies do not harm deck consistency.
- Survives negation as generic material: 2000 ATK WATER Dragon body remains useful even when effect is blanked.
- Widespread practical accessibility: appears in 400/400 sampled decks and 85 distinct archetypes, confirming it is a live option across diverse strategies.
Weaknesses
- Zero card advantage: requires 2 monsters to summon with no refuel, draw, or recovery effect.
- No opponent interaction: the effect is purely self-buffing (ATK increase) and contributes zero disruption, negation, or removal.
- Vulnerable to removal: no inherent protection; once materials are depleted, locked from direct attack and stranded on board.
- Not a combo driver: zero recorded combo board appearances confirm it neither starts nor amplifies meaningful combo lines.
- Filler role, not engine: top deck partners are generic staples (Mirror Force, Solemn Warning, Dark Hole), indicating it fills deck slots rather than driving strategic synergy.
Counters / choke points
- Spot removal (Raigeki, Dark Hole, Lightning Storm, Evenly Matched).
- Cards that prevent Xyz summons or force detachment of materials before the card stabilizes.
- Effect negation (Infinite Impermanence, Nadir Servant) blanks the ATK-pump effect but leaves a static 2000 ATK body vulnerable.
Best use
Stepping-stone Rank 3 Xyz for converting unused Level 3 monsters into material for higher plays.. Decks: Labrynth, The Agent, Secret Six Samurai, T.G., Any Xyz-heavy archetype. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: 'Once per turn: You can detach 1 Xyz Material from this card; this card gains 500 ATK. If this card has no Xyz Material, it cannot attack your opponent directly.' (from card description); Xyz summon requirement: 2 Level 3 monsters (from card description); Appears in 400/400 recent sampled decks spanning 85 distinct archetypes (from deck data); Included in 88% Type 7 (control-oriented) gameplay decks (from deck data formats); Mentioned in 2 guides as extra deck inclusion (from guide data); Average 1.12 copies per deck (from deck data copies per deck)
- Observed: Top deck partners are control/staple cards: Mirror Force (56.5% co-occurrence), Mystical Space Typhoon (55.8%), Solemn Warning (51%), Dark Hole (49.2%), Monster Reborn (49%) (from deck data top partners); 100% inclusion rate in 2 niche archetypes: Batteryman (2 copies typical) and Ally of Justice (1 copy typical) (from usage statistics); Not ranked as a top card in any format (from top-card data top-card status = false)
- Inferred: Primary role is Material body / Utility: based on simple effect text, zero combos, generic Xyz nature, and partnership with control staples rather than synergy enablers.; Stepping-stone function: summoned when deck has spare Level 3s, then converted into higher Xyz or other plays; not an end-board finisher.; Filler rather than engine card: top deck partners (staple spells and traps) show no synergy signals; card appears in decks because it solves the problem of unused Level 3 monsters, not because it drives strategy.
- Data gaps: No combos supplied: cannot confirm if card appears in real combo lines or powers specific board states; combo_conversion relies on text-only inference. Usage statistics limited to 2 archetypes (Batteryman, Ally of Justice): does not explain presence in 85 other archetypes or suggest which ones rely on it. No banlist information: legal copies per format assumed unlimited (3 copies); actual restrictions unknown. No top-card ranking: generic Xyz may not be tracked in metagame data; does not indicate weakness but limits format-specific metagame confirmation.
