Batgirl 
Birds of Prey 
Bat Family 
Weapon Master 
Quantum's Take
Batgirl is a supporter who was out of favor in the meta for quite a while, but has become quite useful in [Bat Family] lineups utilizing Nightwing. She does require some investment to get the full potential from her kit. Fair warning: She's a niche champion at the moment, so make sure you're all-in on [Bat Family] and [Teen Titans] before you commit.
