This is a reupload from a previous deck, using the new synchro and moving some proportions in the deck around.
The objective of the deck is to get 4 harpies on the board. Doing this allows you to do the following combo
Link 2 into Romulus
Equip Divine Lance
Equip and Summon Phalanx
Link Phalanx and 1 Harpie for Union Carrier
Link Romulus and other Harpie for Simorgh
Equip Thunderbird to Simorgh with Carrier
Summon Avian in End Phase off Simorgh
If you can only make 3 Harpies:
Link 2 into Conductor
Link into Simorgh
Summon Avian in end phase
With The new synchro, it's best to use it when you know your opponent is going to have a mix deck of monsters and spells/traps, and is good for bouncing indestructibles(good for golden lord after summoned by own effect)
Also keep in mind that Simorgh protects winged beasts it points to from target effects
