Updated deck with the release of Feather Duster. Feather Duster itself is situational, but the combos in this deck can shut down any deck. Feather Storm is the best card in this deck, able to completely shut down hand traps and opponent's big boards in one card. Going first is always optimal. The board is made the moment you're able to get any 4 harpies on the board. Then you go into this combo for Infinite Negates:
Link 2 into Romulus
Search and Equip Lance
Equip and Summon Phalanx
Link Harpie and Phalanx into Union Carrier
Link Romulus and Final Harpie into Simorgh
Equip Simorgh with Thunderbird via Carrier
Summon Avian in End phase via Simorgh
If you go 2nd, then you want to make a board aiming for Aggressive plays dependent on opponents board:
Heavy Backrow: Search for Hunting Grounds and start popping backrow.
Dragun: Bait out negate from Dragun then drop feather storm from hand with normal summoned harpie. Then go into Zerofyne to wipe effects
Golden Lord/Infernobles: Use Cyber Slash to bounce to hand/Extra Deck rather than send to GY.
