You cut basics, get 0 cost repose and as many dupes of it as possible, once you get her upgrades her deck becomes literally only draws, and her ballista damage is nothing to scoff at either, I'm hitting for 700~1400 depending on reload/kowalski
As for ballistas Giant>50% chance>others
Go for 4pc passion/2pc atk, and full atk% main stats because she scales harder with her last potential, for subs go for extra attack.
Fun fact the ballista benefits from the 4pc passion effect, but doesn't reduce a count so its unlimited up time if you remove her basics and don't add an attacking neutral
