A Slot for Karla

Hello everyone, as you seen from the title i rolled on this banner and was lucky enough to get a +Atk -Res one. I wanna keep her default kit but im not sure what would work best in her A slot. I wanted some opinions on an alt as i dnt currently have Swift Sparrow or Distant Counter fodder. Currently i have Steady Blow, Sturdy Blow, Darting Blow, Fury all maxed out. I also have Life & Death 2 but not too keen on it since she can already barely take a hit. Suggestions would be greatly appreciated. Thanks
