The Tripper Mercury — Power Evaluation
Final Score: 48 ± 8 · Confidence: Medium
- Intrinsic: 48 · Deck: 48 · Meta: provisional
- Primary role: Boss / End-board · Secondary: Board breaker
Why it scores here
The Tripper Mercury converts a 3-monster Tribute Summon into a 2000-ATK body that makes every opposing monster lose ATK equal to its original ATK while it stays on the field, plus a second attack per Battle Phase. The ATK-loss effect is what earns the points: it is a board-wide effect that can blank high-ATK opposing monsters, not the 2000 ATK itself. The Tribute cost, the single-copy use, and the fact that the card is a one-card Dinomist-shell finisher with no recorded combo boards keep the score in the middle range. High deck inclusion inside Dinomist confirms the card is practical there, but it does not raise the score by itself.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Only reachable by Tributing 3 monsters, and the evidence has no searcher or recursion route; it is in 19 of 21 sampled Dinomist decks at 1.1 copies on average (observed, decks; Tribute cost is verified from text). |
| Combo & Conversion | 45 | No recorded combo boards (combo data.appearances = 0), so the conversion rating is text-only: one summon that changes battle positions and debuffs the opponent's whole field (inferred). |
| Resource Economy | 15 | Tributing 3 monsters is a steep card cost with no refuel, banish or search in the text (verified, card text). |
| Effect & Interaction | 60 | The ATK-loss effect is a strong, board-wide debuff against opposing monsters while it is on the field, though it depends on the card surviving (verified, card text; strength is inferred). |
| Material Utility | 45 | Level 8 Water Aqua effect monster, a plausible material body if it is ever sent off the field; no recorded material use in combos (inferred). |
| Resilience & Flexibility | 40 | Once on the field it is a single 2000-DEF body that loses its debuff to any removal; no redundancy or second route in the evidence (inferred). |
| Deck-Building Efficiency | 55 | Single-copy slot in a deck built around its own shell (observed, decks: avg 1.1 copies), with no garnet or lock recorded; the Tribute cost limits how often it can be played (verified, decks). |
Calculation
Weight profile: 0.7 Boss/End-board + 0.3 Board breaker. Intrinsic ≈ 48, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Board-wide ATK loss on opposing monsters while on the field (verified, card text)
- Second attack in each Battle Phase adds pressure after the summon (verified, card text)
- Found in 19 of 21 sampled Dinomist decks, so it has a live home (observed, decks)
Weaknesses
- Requires 3 monsters to Tribute, so it is slow to reach (verified, card text)
- No searcher, recursion or refuel route in the evidence (verified, evidence gaps)
- The ATK-loss effect is lost when the card leaves the field (verified, card text)
Counters / choke points
- Removal or send-to-GY effects that end the ATK-loss effect (inferred)
- Monsters with an original ATK low enough that the debuff matters little (inferred)
Best use
Tribute Summon finisher that blanks opposing monsters and attacks twice. Decks: Dinomist. Suggested copies: 1.
Evidence & gaps
- Verified: Tribute Summon requires 3 monsters, and it cannot be Set (card text); Opposing monsters lose ATK equal to original ATK while it is on the field (card text); Can attack a second time in each Battle Phase (card text); Appears in 19 of 21 sampled decks, with 1.1 copies on average (deck data)
- Observed: Dinomist is the dominant home (19 of 21 decks), with consistent Dinomist partners (deck data.top partners)
- Inferred: Its ATK-loss effect is a strong board-wide interaction (text-based judgement); Its Level 8 Water Aqua body is a plausible material (text-based judgement); It is a one-card finisher, not a combo starter (no combo evidence; text-based judgement)
- Data gaps: no combos supplied: combo conversion is text-only inference no banlist token: assumed 3 copies (unlimited) no usage statistics (StatisticsCard): inclusion % inferred from the deck sample only guide mention is about the Trap Monster deck in general, not this card specifically
