Block Attack — Power Evaluation
Final Score: 52 ± 8 · Confidence: Medium
- Intrinsic: 52 · Deck: 52 · Meta: provisional
- Primary role: Board breaker / Going-second
Why it scores here
Block Attack reliably does one thing: it turns one face-up Attack Position monster into a Defense Position monster, which blunts an attacker for a turn without removing it. It is a live staple in 24 of 24 sampled decks across 14 archetypes, usually at one copy, with Monster Reborn, Raigeki and Solemn Judgment as frequent partners, so its accessibility and deck cost are good. Its high-value effect is narrow, it creates no board or card advantage, and it has no combo evidence, so the score stays in the mid-50s and does not reflect how popular it is.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | The card is in 24 of 24 sampled decks, mostly at one copy, and has no searcher or combo routes, so it is reliably in hand but not searchable (observed). |
| Combo & Conversion | 25 | The card text only switches one monster's battle position and builds nothing, and no combo boards were supplied, so conversion is text-only inference (inferred). |
| Resource Economy | 15 | The text gives no draw, search, or recovery, and the card is a one-for-one action with no return (verified). |
| Effect & Interaction | 45 | It disrupts attacking monsters by changing battle position, which is soft interaction that does not remove, negate, or destroy anything (verified). |
| Material Utility | 0 | It is a Spell card and cannot be used as material (verified). |
| Resilience & Flexibility | 40 | It is a single-target spell with no recursion, so one negation ends it, and the sample shows no redundancy evidence (inferred). |
| Deck-Building Efficiency | 80 | It costs one main-deck slot at about 1.2 copies on average, with no garnet or self-lock restriction, and the card is cheap to splash (observed). |
Calculation
Weight profile: Board breaker / Going-second profile only; no secondary role blended. Intrinsic ≈ 52, Deck ≈ 52, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in all 24 sampled decks across 14 archetypes, so it has broad homes
- Cheap to run at about one copy with no restrictions
- Answers a standing attacker without needing a monster body or a search
Weaknesses
- Changes battle position only; it does not destroy, negate or remove the monster
- Creates no board, card advantage or recovery
- Vulnerable to a single spell negation, and the sample shows no redundancy
Counters / choke points
- Negation of the spell itself (no specific counter cards are named in the evidence)
- Decks that do not attack, or that set monsters, make it dead
Best use
Single-copy board breaker / battle-position answer in a 1-copy staple slot. Decks: Solemn Judgment / control-style lines, Gravekeeper's, Hole, Gaia The Fierce Knight. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: targets one face-up Attack Position monster the opponent controls and changes it to face-up Defense Position; Card type is Spell, so it cannot be material; Usage at 1.21 copies average, max 3, with 20 of 24 decks at one copy
- Observed: Present in 24 of 24 sampled decks across 14 archetypes; Top partners: Monster Reborn 79.2%, Raigeki 62.5%, Solemn Judgment 62.5%
- Inferred: Battle-position change is a soft board breaker, not removal; Single negation would end its effect
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies assumed (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is from the deck sample only card text gives no timing (Normal vs Quick-Play), so timing-based interaction is unconfirmed
