The Tyrant Neptune — Power Evaluation
Final Score: 41 ± 8 · Confidence: Medium
- Intrinsic: 41.5 · Deck: 41.1 · Meta: provisional
- Primary role: Utility · Secondary: Boss/End-board
Why it scores here
The Tyrant Neptune converts a tributed monster in the Graveyard into a copy of that monster's name and effects, so its value depends on what is in the GY and on paying a monster for the Tribute Summon. The text describes a flexible copy route, but there is no combo or searcher evidence to show it reliably reaches a strong board. Its 5 recorded decks across 4 archetypes show it is playable, not that it is powerful, so the level-10 body and the 0-ATK/DEF stats earn nothing by themselves.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 40 | The card is a hand-only Tribute Summon with no searcher, and it is run as one copy in 5 decks, so access is conditional on a tribute and a GY target (inference, with observed deck counts). |
| Combo & Conversion | 45 | The copy effect can turn a GY monster into a stronger effect body, but no combo boards were supplied, so conversion is text-only inference. |
| Resource Economy | 30 | Tributing a monster is a cost paid for the summon and the card gains no refuel or card advantage from the text (verified from card text). |
| Effect & Interaction | 15 | The text contains no negation, removal, or hand-trap effect, so opponent interaction is effectively absent (verified from card text). |
| Material Utility | 35 | It is a Level-10 Reptile WATER body that is not a clean generic material, and the tribute route consumes a monster rather than creating material value (inference from text). |
| Resilience & Flexibility | 35 | Its single targeted effect depends on one GY monster and no redundancy or multi-turn value is shown in the evidence (inference from text). |
| Deck-Building Efficiency | 55 | It is a single-copy card with no garnet or lock restriction in the evidence, though the tribute requirement adds a slot cost (observed deck counts with text inference). |
Calculation
Weight profile: 0.7 Utility + 0.3 Boss/End-board. Intrinsic ≈ 41.5, Deck ≈ 41.1, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Copy-effect route can take on a useful GY monster's effect after a Tribute Summon
- Playable across 4 distinct archetypes in the deck sample
Weaknesses
- No interaction or negation in the text
- Requires a tribute and a suitable GY target, so access is conditional
- No recorded combo boards to confirm a reliable line
Best use
Flexible copy body that depends on the Graveyard. Suggested copies: 1.
Evidence & gaps
- Verified: Cannot be Special Summoned and requires a Tribute Summon by tributing 1 monster; Gains the original ATK and DEF of the tributed monster(s); On Tribute Summon, copies the name and effects of a tributed effect monster in the Graveyard; Run as one copy in 5 of 5 sampled decks
- Observed: Appears in 5 decks across 4 archetypes, with 3 Kaiju partners in the top list; No combo boards recorded, so combo appearance is 0%
- Inferred: Access depends on having a monster to tribute and a Graveyard target; Its utility is mainly as a copy body rather than as interaction or a searcher
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard), so archetype inclusion is inferred from the 5-deck sample only
