The deck is centred around the swarming ability of Blackwings and hitting hard with its Synchros, which can easily access when going second to perform OTKs.
When going first, it has access to half the combo of the Infinite Negates build (Simorgh, Infinity, Apex Avian) which makes a very good 2-Negate 1st turn board.
It is fairly consistent and its easy access to Black Whirldwind and Allure of Darkness helps the situation a lot.
The Deck rarely bricks, but when it does it's an instant loss (the majority of the times).
And it's fragile playstyle does not help either when the player draws bad hands.
Overall, the deck is extremely fun to play but besides the most versatile build, it is definitely not a top contender.
