Blackwing

The Blackwing, known as Black Feather in the Japanese version, monsters are an Archetype of DARK Winged Beast-Type monsters making their debut in "Crimson Crisis". In the Yu-Gi-Oh! 5D's anime, they were first shown during the 30th episode by Crow, who is a new character within the series. Most of these monsters have either a tengu or ravenlike appearance.

When Crimson Crisis was released, this Archetype was very unsupported - only 5 cards of Blackwing were released: Gale the Whirlwind, Sirocco the Dawn, Bora the Spear, Armor Master and "Raptor Wing Strike". Later on, with the release of Raging Battle more members and support cards were added.

Playing Style
The Blackwing's effects are focused around Swarming and changing the ATK or the DEF of monsters on the field. Because of that, they're having an aggressive playing style. Also, because of their Swarming capabilities, they are good for using Synchro Summon (Note that their trump cards are Synchro Monsters). Their support cards rely on their swarm abilities such as Delta Crow - Anti Reverse which can be activated from the hand when there are at least 3 Blackwing Monsters. Some of them taking an advantage from Blackwing's swarming abilities and support it such as Jet-Black Whirlwind or "Raptor Wing Strike". Some of them rely on your opponent such as Fake Feather or Blackwing - Blizzard of the North Pole which need a monster in the Graveyard to Special Summon.

Also, since all Blackwing monsters are DARK Winged Beast monsters, you can add Allure of Darkness for drawing power and Icarus Attack for extra card destruction, if you can't get Delta Crow - Anti Reverse. It`s also possible to play Mountain or Harpies' Hunting Ground to boost their ATK and DEF. Their DARK Attribute also qualifies them for DARK support cards from Phantom Darkness. And since a few of the Blackwing monsters require another Blackwing monster for their effects, you can use Phantom of Chaos to copy both the name and the effects.

Weaknesses
Since most Blackwing monsters can be Special Summoned, its swarming capabilities can be hampered by Fossil Dyna Pachycephalo, "Barrier Statue" cards except "Abyss", Royal Oppression, Jowgen the Spiritualist, Special Hurricane, Vanity's Fiend and Vanity's Ruler. This can be countered with Sirocco the Dawn. Using Trap Hole and Bottomless Trap Hole with Summon Limit can also hurt the user, since he/she will have an open field and would have used up their hand to swarm.
