Hello all, I'm in need of advice once again. I have been building a budget Blackwing deck for my cousin and I would like your input. Here's what I have so far:

Main (42):
Monsters (25):
3 Blackwing - Blizzard the Far North
3 Blackwing - Bora the Spear
2 Blackwing – Breeze the Zephyr
2 Blackwing – Elphin the Raven
2 Blackwing – Fane the Steel Chain
1 Blackwing - Gale the Whirlwind
1 Blackwing - Kalut the Moon Shadow
3 Blackwing - Shura the Blue Flame
3 Blackwing - Sirocco the Dawn
2 Blackwing - Vayu the Emblem of Honor
1 Dark Armed Dragon
1 Marshmallon
1 Spirit Reaper

Spells (11):
1 Allure of Darkness
1 Black Whirlwind
1 Lightning Vortex
1 Foolish Burial
1 Card Destruction
1 Cards for Black Feathers
1 Gold Sarcophagus
1 Monster Reborn
2 Mystical Space Typhoon
1 Pot of Avarice

Traps (6):
1 Delta Crow - Anti Reverse
2 Icarus Attack
1 Mirror Force
2 Magical Cylinder

Extra Deck ( cool :
1 Red Dragon Archfiend
1 Blackwing - Silverwind the Ascendant
2 Blackwing Armed Wing
2 Blackwing Armor Master
1 Black-Winged Dragon
1 Stardust Dragon

Side Deck (15):
1 Aurkus, Lightsworn Druid
2 Garoth, Lightsworn Warrior
1 Gragonith, Lightsworn Dragon
2 Jain, Lightsworn Palidan
1 Lumina, Lightsworn Summoner
1 Jenis, Lightsworn Mender
1 Ryko, Lightsworn Hunter
1 Shire, Lightsworn Spirit
1 Judgement Dragon
3 Chaos Sorcerer
1 Solar Recharge

Before you say anything, yes I'm aware 2 Elphin and 3 Sirocco is excessive. I was just experimenting. Obviously this build is just for fun, not real competitive play. Let me know what you all think would make this thing better. Thanks in advance!
