Wall of Disruption — Power Evaluation
Final Score: 58 ± 6 · Confidence: Medium
- Intrinsic: 58.5 · Deck: 56.9 · Meta: provisional
- Primary role: Board breaker / Going-second
Why it scores here
Wall of Disruption converts a single set Trap into a board-wide ATK reduction, but only when the opponent declares an attack, so its value depends on the opponent choosing to attack into it. The effect interaction axis earns most of the score because each attacking Attack Position monster loses 800 ATK per opposing monster, which can stop attacks in battle. Its high deck count and wide archetype spread confirm it is a reliable staple rather than a niche pick, but that frequency is not used to inflate the score, and no combo evidence exists to raise combo conversion. Material utility is near zero because a face-down Trap is never a body.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Present in 201 of the attached decks across 102 archetypes, but it is a set Trap with no searcher or starter route in the evidence, so hand access is inferred (observed; route inferred). |
| Combo & Conversion | 30 | No recorded boards contain it, so conversion rests on the text alone: a reactive attack-triggered ATK drop that only converts when the opponent attacks (inferred). |
| Resource Economy | 40 | A one-for-zero trap that spends itself for a board-wide effect, with no refuel, search or recursion in its text (verified). |
| Effect & Interaction | 70 | Each attacking Attack Position monster loses 800 ATK per opposing monster, which can make attacks fail in battle; it does not stop effects, and its impact is conditional on an attack declaration (verified text; impact inferred). |
| Material Utility | 5 | A Trap card cannot be used as Material or as a body, so the axis is near zero (verified). |
| Resilience & Flexibility | 45 | A single set Trap that one trap negation can stop, but it is spread across many archetypes and copy counts, which gives some redundancy (inferred). |
| Deck-Building Efficiency | 80 | A plain 1 to 3 copy staple with no garnet, lock or self-restriction in its text, so it is cheap to run and easy to splash (verified). |
Calculation
Weight profile: Single primary role, Board breaker / Going-second; no secondary blend. Intrinsic ≈ 58.5, Deck ≈ 56.9, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Attack-triggered board-wide ATK reduction that can stop several attacks in one trigger
- Appears across 102 archetypes with 201 attached decks, so its role is real and practical
- Cheap, generic slot with no garnet or self-lock restriction
Weaknesses
- Only converts when the opponent declares an attack, so it does nothing against a passive board
- Zero recorded combo boards, so its conversion value rests on text inference
- Does not stop effects or card advantage, and gives no resource return
Counters / choke points
- Trap-negating or trap-destroying cards (inferred)
- Opponent not attacking into an Attack Position board (inferred)
Best use
Board breaker / attack punisher. Decks: Odd-Eyes, Harpie, Performapal, Blue-Eyes, Trap Monster. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: attack-triggered 800 ATK loss per opposing monster on Attack Position monsters; Trap card type with no material or summon role; 201 of 201 attached decks run it in main deck
- Observed: 102 distinct archetypes across attached decks; Average 1.68 copies per deck; Guides cite it as a tech card
- Inferred: Hand and board access rely on generic staples rather than a dedicated searcher; Practical impact is strongest against attacking boards
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token; legal copies is empty so 3 copies is assumed usage statistics covers only 2 archetypes no rulings supplied for timing interactions
