Here are my picks:
Wonder Woman - The public face of the League and the in-field leader
Barbara Gordon - The woman in the chair, tech support, coordinator from base
Black Canary - The heart of the team
Huntress - The one ready for a good fight, will keep on fighting no matter what
Zatanna - Their expert in all things magic
Starfire - An alien powerhouse with a constant upbeat attitude
Miss Martian - The one who will defend her team, no matter what
Power Girl
Batgirl (Barabra Gordon)
Zatanna
Jessica Cruz
Jesse Quick

Those are both incredible squads!!!
My squad is built with females who’ll go there if necessary (Huntress, Catwoman, Cheshire, even Zatanna (Identity Crisis)-& some level headed world beaters.
