Blackwing's fly together [written]

[Loleo]

Blackwing- birds of a feather fly together

continuous spell

All "Blackwing" monsters are now treated as WIND and DARK. All "Blackwing" monsters gain 100ATK for each WIND and/or winged beast on either players field and GY. If a "Blackwing" card would be destroyed except during damage calculation, return one "Blackwing" from the field to the hand and negate the card with that effect.

(Improved wording please)

Attribute of "Blackwing" Monsters on the field also treated as WIND they also gain ATK equal to total number of either WIND and/or Winged-beast monster on either players field and GY x100. When "Blackwing" Monster(s) would be destroyed by card effect, its controller can return a "Blackwing" he/she control instead.

Idk this is the wording you want. Your original wording pretty vague. 

As the (temporary) review i dont think blackwing really want this even sizable stat boost it offer. while its fun to get access to things like Dark Simorgh, the birds has its own way to pay its advantage with decent bosses (heck they have a god card with that latest Armor Master)

Face-up "Blackwing" monsters are also WIND-Attribute.  All "Blackwing" monsters gain 100 ATK for each WIND or Winged-Beast monster on the field.  If a "Blackwing" card would be destroyed by a card effect: You can return 1 "Blackwing" monster you control to the hand, and if you do, negate that effect.

I'm not sure how to interpret the ATK boost (does it gain 200 from a WIND/Winged-Beast, or only 100?), but I tried fixing up the rest of the wording.  As a sidenote: if your opponent was playing Blackwings, this would boost their monsters as well.
