Impenetrable Attack — Power Evaluation
Final Score: 38 ± 6 · Confidence: Medium
- Intrinsic: 35 · Deck: 40 · Meta: provisional
- Primary role: Utility
Why it scores here
Impenetrable Attack is a Normal Trap that only works in the Battle Phase: it keeps one monster from being destroyed by battle or card effects, or stops battle damage to you. Its text converts nothing into board, cards or material, and the combo sample is empty, so it earns no conversion or resource points. Its presence in 25 recent decks across 12 archetypes confirms it is a practical, cheap staple, but guardrail 3 means that frequency is not treated as power, and the score stays in the lower-middle range.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 40 | Set-and-hold trap with no searcher in the evidence; it is live only if drawn or kept, and it appears in 25 decks at about 1.4 copies per deck (observed, plus inference that no search route is supplied). |
| Combo & Conversion | 10 | Zero combo appearances and no examples; the card only protects an existing monster and builds nothing on its own (verified text, observed absence). |
| Resource Economy | 10 | No draw, search, refuel or card advantage in the text; it is a one-for-one protective card (verified). |
| Effect & Interaction | 20 | Protective rather than disruptive: it does not negate or remove an opponent's card, so only a narrow Battle Phase defence is provided (verified text, inferred weight). |
| Material Utility | 0 | Spell/Trap card with no material or level value at all, so it contributes nothing once face-up or used (verified). |
| Resilience & Flexibility | 35 | Usable in two modes, but only during the Battle Phase and only as a trap that must survive set-state interaction; activation can be negated (inferred). |
| Deck-Building Efficiency | 60 | One slot at 1-2 copies, no garnets or locks, and easy to splash across archetypes; the cost is a dead-card risk outside the Battle Phase (verified copies, inferred risk). |
Calculation
Weight profile: Utility default weights (no clear primary role); no secondary role blended. Intrinsic ≈ 35, Deck ≈ 40, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Protects one monster from battle and card-effect destruction during the Battle Phase (verified)
- Prevents battle damage to you during the Battle Phase (verified)
- Cheap, flexible one-slot staple across 12 archetypes in the sample (observed)
Weaknesses
- Works only in the Battle Phase; dead outside it (verified)
- No card advantage, board presence or material value (verified)
- Must be set and survive until activation, so it is exposed to set-state interaction (inferred)
Counters / choke points
- Activation-negation effects can stop the trap before it resolves (inferred; Ash Blossom & Joyous Spring appears as a partner in the sample)
- Opponents who keep to non-battle lines simply make the Battle Phase protection irrelevant (inferred)
Best use
Battle Phase protection trap, one copy as a generic staple. Decks: Wind-Up, Utopia, Hole. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Battle Phase only; target 1 monster to be protected from battle and card-effect destruction; or no battle damage to you; 25 of 400 sampled decks run it, 72% in gameplay type 7, average 1.4 copies per deck; 12 distinct archetypes, with top partners Mystical Space Typhoon (15 decks), Monster Reborn (14), Bottomless Trap Hole (13)
- Observed: Zero combo appearances in the supplied combo evidence; Usage statistics show one archetype (Grepher, 100% inclusion, 3 copies) from a very small sample; Not a Top Card in any format
- Inferred: Primary role is a protective Battle Phase trap, which is closest to Utility; Can be negated when activated, and cannot be material; No search route exists in the evidence, so access depends on draw and retention
- Data gaps: no combos supplied: combo conversion is text-only inference no guides supplied no banlist token and legal copies is empty: assumed 3 copies (unlimited) usage statistics cover one archetype only (Grepher), a very small sample no rulings supplied for timing interactions
