Rate/fix my new blackwing deck.?

It's not too good. There's too many useless cards (Elphin, Backlash, Gust, Thunder, etc.) and not enough staples (Icarus Attack, 2 Black Whirlwinds, Gale, etc.). In the end, go for something like this:

3 x Blackwing - Kalut the Moon Shadow

3 x Blackwing - Bora the Spear

3 x Blackwing - Shura the Blue Flame

2 x Blackwing - Vayu the Emblem of Honor

2 x Blackwing - Blizzard the Far North

2 x Blackwing - Sirocco the Dawn

1 x Blackwing - Breeze the Zephyr

1 x Blackwing - Gale the Whirwind

1 x Dark Armed Dragon

1 x Dark Grepher

Spells (11)

2 x Black Whirlwind

2 x Book of Moon 

1 x Allure of Darkness

1 x Cards for Black Feathers

1 x Foolish Burial

1 x Burial from a Different Dimension

1 x Heavy Storm

1 x Mystical Space Typhoon

1 x Brain Control

Traps (10)

3 x Icarus Attack

2 x Bottomless Trap Hole

2 x Royal Oppression

1 x Trap Dustshoot

1 x Solemn Judgment

1 x Torrential Tribute

Synchro Monsters (15)

3 x Blackwing Armor Master

3 x Blackwing Armed Wing

1 x Stardust Dragon

1 x Infernity Doom Dragon

1 x Blackwing - Silverwind the Ascendant

1 x Brionac, Dragon of the Ice Barrier

1 x Magical Android

1 x Colossal Fighter

1 x Black Rose Dragon

1 x Goyo Guardian

Email me if you have any questions.

well this is pretty good but I would have to say you need 2 black whirlwinds and 3 icarus attack and you probably want cards that can deflect traps and spells and effects so I guess you probably have some but ya so here is a list of cards u may need...

x3 icarus attack

1 more black whirlwind

u probably have them but the blackwing sincro monsters

maybe take out fane of the steel chain unless he is used for sincro

x1 gale

1 less book of moon

i think that you got a tough to beat deck being that blackwing monsters can special summon each other, also you have the right spells and traps.
