Trap Jammer — Power Evaluation
Final Score: 49 ± 6 · Confidence: Medium
- Intrinsic: 49.3 · Deck: 48.6 · Meta: provisional
- Primary role: Removal / Negation
Why it scores here
Trap Jammer is a narrow, reactive negation: it only answers a Trap Card activated during the Battle Phase, and its value is the negate-and-destroy trade against that one trap. Its 35-deck sample across 20 archetypes (1.34 copies average, mostly one copy) confirms it is a practical, cheap-to-run slot, and it is played alongside broad backrow staples such as Infinite Impermanence and Mirror Force. The card has no combo evidence and no usage statistics, so its combo and conversion scores stay low. High deck counts were not allowed to raise the score: its breadth reflects generic utility, not stronger power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Reached as a set backrow card with no searcher or draw route in the evidence; live in the backrow once set (verified text, no combo stat) (inferred). |
| Combo & Conversion | 15 | No combos are supplied and the card builds nothing by itself; conversion is text-only inference (inferred). |
| Resource Economy | 50 | A one-for-one trade: it spends itself to negate and destroy one Trap activation, with no refuel or card advantage (verified text) (inferred). |
| Effect & Interaction | 45 | Negates and destroys a Trap activation, but only during the Battle Phase and only against Traps, which is situational (verified text). |
| Material Utility | 5 | It is not a monster and cannot be used as material (verified card type) (verified). |
| Resilience & Flexibility | 35 | Sits in the backrow where it can be destroyed or bypassed, and it covers a single timing window (inferred from text). |
| Deck-Building Efficiency | 60 | Costs one slot at about 1.34 copies on average, with no garnet or lock restriction in the evidence (observed from deck sample). |
Calculation
Weight profile: Removal / Negation profile; no secondary role blend. Intrinsic ≈ 49.3, Deck ≈ 48.6, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean, reliable negate-and-destroy trade against a Trap in the Battle Phase
- Cheap and easy to run, with about 1.34 copies per deck on average
- Spread across 20 archetypes and several gameplay types, so it has many homes
Weaknesses
- Narrow timing window: it only answers Trap activations during the Battle Phase
- Does not answer Spells, Monsters, or Trap effects outside the Battle Phase
- Has no combo or conversion value, and no usage statistics support it
Counters / choke points
- Trap-destruction and backrow removal that clears it before it is needed
- Opponent plays that avoid Trap activations during the Battle Phase
Best use
Situational Battle Phase negation of Trap activations. Decks: Decks that run Trap-heavy backrow interaction (such as Infinite Impermanence and Mirror Force shells). Suggested copies: 1.
Evidence & gaps
- Verified: Text: negates a Trap activation during the Battle Phase and destroys it if it does so; Card type is Trap Card, so it cannot be material; Run in 35 of the sampled decks across 20 archetypes at 1.34 copies on average
- Observed: Most frequent partners are backrow staples (Infinite Impermanence 42.9%, Mirror Force 37.1%); Gameplay spread: 42.9% in gameplay type 6, 37.1% in type 7
- Inferred: Narrow Battle Phase window limits its practical reach; Roughly a one-for-one trade in resources
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no banlist token — assumed 3 copies (unlimited)
