Can someone plz help with my blackwing deck?

this is a mediocer blackwing deck. it will play well, but only if you have access to the synhros. you dont even play plaguespreader zombie. he is a must in this deck. and if you want to make this deck even more playable, get 3 vayus ($40 a pop), 2 foolish burials and 2 dark grephers, then it will be pretty darn good. i would take out the 2 dark eruptions, 2 threatening roars, darklord zerato, dark creator, and cyber dragon to make these changes. those changes will move it into the range of a tier 1.5 deck. as your deck stands now its a lower tier 1.5, most likely closer to a tier 2 deck.
