Water Leviathan @Ignister — Power Evaluation
Final Score: 60 ± 8 · Confidence: Medium
- Intrinsic: 58.1 · Deck: 61.4 · Meta: provisional
- Primary role: Board breaker · Secondary: Removal/Negation
Why it scores here
The card's value comes from its Ritual Summon trigger: it returns every opponent monster with 2300 or less ATK to the hand, which is a real board-clearing effect. It also gives a once-per-turn ATK-0 effect that costs Link monsters from the GY and a once-per-battle ATK halving in damage calculation, so it covers both board and battle interaction. The 2300 ATK body and the 2000 DEF did not earn any points; the score rests on the effects and on deck evidence that it is routinely played alongside A.I.'s Ritual across 24 archetypes, which confirms the role is practical but does not raise its intrinsic power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Summon depends on A.I.'s Ritual plus Level 7 materials; it is observed in 164 decks and co-occurs with A.I.'s Ritual in 68.3% of them, but no combo data confirms starter or searched routes (observed/inferred). |
| Combo & Conversion | 60 | A Ritual Summon bounces all opposing monsters at or below 2300 ATK, a large board effect from one card, but no combo boards were supplied to confirm conversion (verified text, inferred impact). |
| Resource Economy | 35 | The bounce is tempo rather than card advantage, and the ATK-0 effect's GY Link return is a cost with no recovery, so the card nets roughly even (verified text, inferred). |
| Effect & Interaction | 65 | Strong on-summon mass bounce, a quick-effect ATK halving in battle, and an ATK-0 targeting effect give several interaction points; the bounce is gated by the Ritual Summon (verified text). |
| Material Utility | 40 | No material or Tuner information is supplied; as a Level 7 Water Cyberse Ritual body it is a conventional material-to-summon piece, but the text gives no evidence it converts when negated (inferred). |
| Resilience & Flexibility | 45 | Each effect is once per turn or once per battle and the body is a single 2300 ATK monster, so it has limited redundancy and is vulnerable to a summon-negation response (verified text, inferred). |
| Deck-Building Efficiency | 55 | Observed in 155 of 164 decks at one copy each, which is cheap, but it requires a Ritual Spell and specific materials, so it locks the deck into a ritual package (observed/inferred). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Removal/Negation. Intrinsic ≈ 58.1, Deck ≈ 61.4, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- On-summon mass bounce of opposing monsters at or below 2300 ATK (verified text)
- Quick-effect ATK halving during damage calculation, once per battle (verified text)
- Played in 164 recent decks across 24 archetypes, mostly as a single copy (observed)
- Frequently co-occurs with A.I.'s Ritual (68.3%) and other @Ignister support (observed)
Weaknesses
- Requires A.I.'s Ritual and specific Level 7 materials to reach the field (verified text)
- Effects are gated by once-per-turn and once-per-battle limits (verified text)
- No combo evidence to confirm the bounce converts into a winning board (data gap)
- Only a 2300 ATK body, so it is weak to larger monsters outside the bounce threshold (verified text)
Counters / choke points
- Summon negation or interruption of the Ritual Summon (inferred from text; no counter data supplied)
- Opponent monsters above 2300 ATK are not bounced by the effect (verified text)
Best use
Board breaker. Decks: @Ignister, Firewall, Mathmech, Code Talker. Suggested copies: 1.
Evidence & gaps
- Verified: Ritual Summon via A.I.'s Ritual (card text); On Ritual Summon, return opponent monsters with 2300 or less ATK to hand (card text); Once-per-turn ATK-0 effect that returns Link monsters from GY to Extra Deck (card text); Once-per-battle ATK halving in damage calculation (card text)
- Observed: Appears in 164 decks, 155 at one copy (deck evidence); Co-occurs with A.I.'s Ritual in 112 decks (68.3%) (deck evidence); Spread across 24 archetypes (deck evidence)
- Inferred: Bounce is tempo rather than card advantage; Board impact of the bounce is high but unconfirmed by combos; Summon negation would stop the bounce
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no material or Tuner information in text or evidence
