“Blackwing” is an archetype of mostly DARK Winged Beast-Type monsters that focus on swarming the field to then Special Summon powerful Synchro monsters.
If you had high hopes for this archetype, you were probably left disappointed by the contents of Blackstorm Rising: Blackwings were given the tools to swarm the field, but, as of right now, they severely lack options when it comes to the Extra Deck.
Black Whirlwind allows you to continuously replenish your resources by adding “Blackwing” monsters from your Deck to your hand every time a “Blackwing” monster is Normal Summoned to your side of the field.
You can only add to your hand a monster with less ATK than the one you have Normal Summoned with this effect, which means that Blackwing - Mistral the Silver Shield is essentially the only one you don’t want to start with.
If you add Blackwing - Bora the Spear or Harmattan the Dust to your hand with Blackwing Whirlwind’s effect, you will be able to Special Summon them from your hand right away thanks to their effects.
While it’s entirely possible to play this deck without this Continuous Spell, it is definitely a card you want to have multiple copies of: you are forced to run a minimum of 22 cards because of Mark of the Dragon - Tail, so something like Blackwing Whirlwind that is able to progressively thin your Deck is obviously going to help you out.
When Blackwing - Shura the Blue Flame destroys an opponent’s monster by battle and sends it to the Graveyard, you can Special Summon Blackwing - Harmattan the Dust or Blackwing Mistral the Silver Shield from your Deck, but its effects will be negated.
There are a couple cards you can include in your deck to take advantage of Shura the Blue Flame’s effect, but with the limited amount of Synchros we have available and no Main Phase 2, it will mostly not be worth it.
If you Normal Summon Shura the Blue Flame while Whirlwind is active, you will be able to add any of the other “Blackwing” monsters to your hand.
Blackwing - Blizzard the Far North is a great Tuner that, when Normal Summoned, is able Special Summon a Level 4 or lower “Blackwing” monster from your Graveyard in Defense Position.
You can add Blizzard the Far North to your hand with Black Whirlwind and Normal Summoning Blackwing - Shura the Blue Flame or Blackwing - Bora the Spear and then, if they end up being destroyed, you can Special Summon them from the Graveyard and go into a Level 6 Synchro such as Blackwing Armed Wing.
Just like Blackwing - Bora the Spear, Harmattan the Dust can be Special Summoned from your hand if you control a face-up “Blackwing” monster with a different name, it’s a Level 2, which makes it very versatile when it comes to Synchro Summoning, and it is pretty much needed if you want to Summon Blackwing - Silverwind the Ascendant Consistently.
You can add Harmattan the Dust to your hand with Whirlwind and Normal Summoning Blackwing - Blizzard the Far North, Special Summon Bora the Spear or Shura the Black Flame from the Graveyard and then Special Summon Harmattan the Dust from your hand to go into a Level 8 Synchro.
When Harmattan the Dust is Normal or Special Summoned, it can increase its Level by the Level of another “Blackwing” monster you control.
You can use this effect to make Harmattan the Dust a Level 4 monster and then Special Summon Blackwing Armed Wing using Blizzard the Far North or make it a Level 6 by targeting Bora the Spear or Blackwing - Shura the Blue Flame and then Special Summon Stardust Dragon using the Level 2 Tuner.
Blackwing - Mistral the Silver Shield is mainly used for what he is, which is a level-2 Blackwing Tuner, not for his effect. Because of his low attack, he can always be searched by Black Whirlwind as long as you summon any other Blackwing Monster in this deck.
His effect is only useful when you really need to stall. Place him face-down and wait for your opponent to destroy him. The next battle damage you receive that turn will then be reduced to 0.
King's Consonance essentially lets you Synchro Summon during your opponent's turn with monsters from your graveyard as materials. Because King's Consonance requires your opponent to declare an attack before you activate it you might not be able to use this card if you are in a winning position.
Summon Blackwing - Silverwind the Ascendant and use his effect to get rid of your opponent's monsters without affecting your own battle phase.
The Extra Decks
This deck is able to Summon Level 6 Synchros with relative ease, the only issue is that we don’t have that many at all to choose from.
Blackwing Silverwind the Ascendant is a Level 8 Synchro with an extremely powerful effect, but you have to use at least 2 non-Tuner monsters in order to Special Summon it from your Extra Deck.
When Blackwing - Silverwind the Ascendant is Synchro Summoned, it allows you to destroy up to 2 face-up monsters on the field with DEF lower than its ATK, so, while it is not able to naturally get over a Blue-Eyes White Dragon, a Cosmo Brain or a Masked HERO Anki, it can still get rid of them quite easily.
Once per turn, Silverwind Ascendant also prevents your first “Blackwing” monster that would be destroyed from being destroyed by battle or card effect. Silverwind Ascendant would honestly be a great card if it wasn’t for how difficult it is to Summon it.
Since Blackwing - Blizzard the Far North is not available yet in any other way, this is the best Skill you can run with this deck at the moment. If the Level 2 Tuner will be released in a future BOX, Balance might become a decent option.
Getting multiple “Blackwing” monsters on the field is not that big of an issue, as most of them are either able to Special Summon themselves from the hand or at least Special Summon another monster of their own archetype, the real problem is that there is very little you can do afterwards with these monsters.
