Are Blackwings the New Meta???

To answer the question, no.  Blackwings never were and never will be Tier 1.  They do however have some new support to make them an interesting rogue deck.

Since we got Black Sonic and Gale back to 3, people have been testing some variations of the deck in the current meta.  The overall conclusion is that it's really bad, but fortunately we just got some new cards in PG2 that give it a slimmer of hope.

Let's start with the effect monsters: we've got two of them, Kris the Crack of Dawn and Pinaki the Waxing Moon.  Kris is great: like Bora and Gale, he special summons himself if you have another blackwing, but he's got an additional effect; although you can only special summon him once that way each turn, he can't be destroyed by your opponent's card effects once per turn.  Not amazing, but definitely a lot more consistent than most blackwings.  He's also a 1900 atk beater, so if you normal him, you can pretty much search anything short of Sirocco with Black Whirlwind.

Pinaki is interesting; he's pretty much Blackwings' own Harpie Harpist.  During the end phase of the turn he's sent to the grave from the field, you add any Blackwing from your deck to your hand, so you can use him as synchro material, then search with him during the end phase.  Like Kris, on his own he isn't amazing, but he definitely adds consistency and search power to the deck.

I think the best additions to the deck are the two new synchro monsters we got: Nothung the Starlight and Blackwing Tamer - Obsidian Hawk Joe.  Nothung is a level 6 that completely takes advantage of Black Whirlwind.  When he's summoned, he inflicts 800 burn to your opponent, then decreases the attack of one monster your opponent controls by 800.  His big effect however, is that while he's on the field you can normal summon an additional Blackwing each turn, which works very well indeed with Black Whirlwind.  It effectively lets you make multiple plays each turn.

Hawk Joe is absolutely amazing.  He's a level 7 with two great effects.  While he's live, he has a quick effect that lets you redirect your opponent's attacks or card effects that target him to another blackwing once per turn.  In addition, he lets you special summon any level 5 or higher blackwing from your grave once a turn.  So...any blackwing synchro that's dead, or Sirocco.  Oh wait, if you have an Armor Master or another Hawk Joe in your grave, that's an instant Big Eye, or Dracossack.  Yeah, he's pretty much amazing late-game.

So to summarize, blackwings aren't and never will be top tier, but they have new support that gives the deck more combos and makes it really fun to play.  That being said, I certainly don't expect to see a blackwing deck top in anything higher than perhaps regionals.
