Black Sonic — Power Evaluation
Final Score: 58 ± 8 · Confidence: Medium
- Intrinsic: 56 · Deck: 59 · Meta: provisional
- Primary role: Board breaker · Secondary: Hand trap
Why it scores here
Black Sonic is a reactive trap: when an opponent's monster attacks a Blackwing you control, it banishes every face-up Attack Position monster the opponent controls, which is a one-card multi-body answer. Its strength is that it converts a single attack declaration into a large board swing, and it can also be activated from hand when you control exactly three Blackwing monsters and nothing else. High view count and the 116-deck sample did not earn points; they only confirm the card is consistently played inside the Blackwing shell. The score is held back by the attack-trigger and Attack Position conditions and by the absence of combo or guide data.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Runs in 116 of 116 sampled decks at 1.78 copies on average and sits alongside Black Whirlwind in 96.6% of them, but the hand activation needs an exact Blackwing board (verified from text; deck presence observed). |
| Combo & Conversion | 35 | No recorded combo boards, so the conversion is read from text alone: it turns an opponent attack into a mass banish, not a build-out (inferred). |
| Resource Economy | 55 | Banishing several Attack Position monsters at once is a large card-advantage swing with no refuel or recursion (verified from text; no measured netCardAdvantage). |
| Effect & Interaction | 65 | Mass banish of Attack Position monsters on an attack on a Blackwing is strong interaction, bounded by its trigger and position limits (verified from text). |
| Material Utility | 5 | It is a trap card and cannot be used as material or as a name/level/attribute provider (verified from card type). |
| Resilience & Flexibility | 45 | A single trap that a generic negation can stop, with no redundant body or recursion; copies provide some redundancy across 1.78 average copies (inferred from text and deck stats). |
| Deck-Building Efficiency | 70 | Runs as a single-copy-friendly trap inside a deck whose archetype is already Blackwing, so the restriction is mild and copies are cheap (observed from deck stats). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Hand trap. Intrinsic ≈ 56, Deck ≈ 59, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Banishes all face-up Attack Position monsters the opponent controls in one activation
- Live in 116 of 116 sampled decks, typically at 2 copies
- Can be activated from hand when the Blackwing board is exactly three Blackwing monsters
Weaknesses
- Trigger requires the opponent to attack a Blackwing you control
- Only hits Attack Position monsters, so Defense Position boards are unaffected
- No combo, guide or usage-statistics data to measure how often it lands
Counters / choke points
- Generic negation of the trap or of the attack declaration (inferred; no specific counter cards appear in the evidence)
- Opponent keeping monsters in Defense Position or not attacking Blackwing monsters (inferred from the text)
Best use
Board breaker and hand trap in Blackwing shells. Decks: Blackwings, Tri-Brigade. Suggested copies: 2.
Evidence & gaps
- Verified: Trap card; banishes all face-up Attack Position monsters the opponent controls when an opponent's monster attacks a Blackwing you control; Can be activated from hand when you control exactly 3 Blackwing monsters and no other monsters; Present in 116 of 116 sampled decks, average 1.78 copies
- Observed: Co-occurs with Black Whirlwind in 112 decks (96.6%) and several other Blackwing monsters at 87.9–94%; Gameplay type 7 in 75% of decks
- Inferred: Hand activation is a niche board-state gate rather than a routine play; Reactive value depends on the opponent attacking into a Blackwing board
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only Archetype names repeat across several Blackwings archetype IDs; the evidence does not resolve whether they are distinct homes
