Build

Cube: Like all machine guns; Bastion. Unless you are super unlucky with overload stats and get no max ammunition, in that case run Resilience.

OL Gear: You want 2 good lines of max ammo capacity (or 3 if unlucky with % rolls). After that, focus on Elemental DMG and ATK. You can get crit and hit rate lines as fillers.

Pros & Cons

Synergy with fire Asuka to make her deal even more damage. Staple pick on fire weak raids to put both of them together

She has less voice lines than Makima which is pretty hard to achieve
Damage to shields is a pretty niche mechanic right now that finds no real usage
